IntroDUCtIon<br />

<strong>Highway</strong> <strong>Research</strong> <strong>Record</strong> <strong>No</strong>.<strong>39</strong> describes the General Report on Road <strong>Research</strong> Work done in India during the<br />

year 2011-2012. This document has been prepared by compiling the progress of research work reported by 18<br />

<strong>Research</strong> Organisations and Academic Institutions in the country. The names of reporting organizations have been<br />

listed at the end of the report. As the General Report on Road <strong>Research</strong> is intended to provide information on<br />

research works carried out under various research projects, works reported on routine investigations and laboratory/<br />

field testing have been omitted from the document.<br />

As per the classification, the entire material has been divided into four sections, namely, Pavement Engineering<br />

& Paving Materials; Geotechnical Engineering; Bridge Engineering and Traffic & Transportation Engineering. The<br />

projects in each section are further classified into two broad categories namely (i) Projects Reported First Time, i.e.,<br />

New Projects and (ii) Ongoing Projects/ Completed Projects. The research works carried out as a part of Master and<br />

Doctoral thesis in the Academic Institutions have also been reported separately in Section V of the report.<br />

The research work in each section has been reported as per the standard Proforma for the three broad categories of<br />

projects. The proforma along with other related information are given in Appendix.<br />

Each sectional report begins with a brief overview in the form of summary followed by a few salient points towards<br />

channelising the discussions during the presentation of the report in the IRC Annual session.

GENERAl REPORT ON<br />

eXeCUtIVe SUMMarY<br />

In the General Report on Road <strong>Research</strong> Work Done in India for the year 2011-2012, published as <strong>Highway</strong> <strong>Research</strong><br />

<strong>Record</strong> <strong>No</strong>. <strong>39</strong>, the research work done by 18 organisations on various aspects has been reported. The report has<br />

been compiled by CRRI. The R&D work reported under the following four major areas and the research work done<br />

in Academic Institutions related to the thesis work is reported under Section V:<br />

Traffic & Transportation Engineering<br />

1. pavement engineering and paving Materials<br />

1.1 Flexible pavements<br />

The research topics covered in this section include<br />

development of low energy (warm) PMB and CRMB<br />

mixes, half warm emulsion based bituminous mixes,<br />

reclaimed asphalt pavement (RAP), validation of<br />

flexible pavement design procedure, development of<br />

improved materials and mixes for thinner pavements,<br />

utilization of tannery solid waste, plastic waste and<br />

zycosoil in bituminous mixes, resource mapping of<br />

road construction materials, and prevention of reflective<br />

cracking on bituminous overaly using geotextiles.<br />

laboratory performance of polymer modified bitumen<br />

warm asphalt mixes is better than conventional polymer<br />

modified bitumen mixes indicate suitability of these<br />

mixes for road construction under heavy traffic. Half<br />

warm asphalt mixtures manufactured using cationic<br />

bitumen emulsion investigated in laboratory have<br />

properties identical to traditional hot asphalt mixture.<br />

Mechanistic analysis revealed that cumulative damage<br />

in fatigue will be less in modified pavement as compared<br />

to unmodified pavement. Use of Zycosoil resulted in<br />

faster working, good finishing & glossy water repellent<br />

surface.<br />

1.2 rigid pavements<br />

In this section longitudinal cracking of concrete<br />

pavements on National <strong>Highway</strong>s, utilization of foundry<br />

sand as fine aggregates in concrete road construction,<br />

use of CaSO 4 derived from tannery fleshings in cement<br />

formulation has been discussed. Full depth longitudinal<br />

cracking has led to the premature structural failure<br />

of rigid pavements on many National <strong>Highway</strong>s. An<br />

investigation into the possible reasons of such cracks is<br />

reported. Foundry sand, a waste of foundry industries,<br />

is being investigated for its possible use as a partial<br />

replacement of fine aggregate in cement concrete road<br />

construction.<br />

1.3 pavement evaluation<br />

<strong>Research</strong> work reported in this area includes projects<br />

on structural and functional evaluation of pavements<br />

and pre-mature distress / failure investigations for<br />

pavements. On-going projects include development<br />

of management system for maintenance planning<br />

and budgeting of high speed road corridors (supra<br />

institutional project); development of national document/<br />

guideline on the use of weigh-in-motion system for axle<br />

load monitoring.<br />

Projects reported for the first time include evaluation<br />

of NDMC roads / lanes for needed strengthening and<br />

remedial measures; road inventorisation and pavement<br />

condition survey on the selected road stretches using<br />

vehicle mounted digital video imaging system integrated<br />

with GPS; functional and structural evaluations of DND<br />

flyway and Mayur Vihar link Road towards determining<br />

the maintenance and strengthening requirements.<br />

1.4 pavement performance<br />

This sub-section on pavement performance covers<br />

projects related to laboratory characterization of<br />

materials / mixes and design of Stone Matrix Asphalt<br />

(SMA), Microsurfacing and Hot Asphalt Mixes using<br />

waste plastic; construction supervision and quality<br />

checking during execution of road sections laid with<br />

Stone Matrix Asphalt (SMA), Microsurfacing and Waste<br />

Plastic Modified Hot Mix Asphalt and time series Periodic<br />

Performance Monitoring of road sections laid with<br />

SMA, Microsurfacing and Waste Plastic Modified Hot<br />

Mix Asphalt and finally refinement / revision of present<br />

Codes of Practice viz. IRC: SP: 79-2008 for SMA, IRC:<br />

SP: 81-2008 for Microsurfacing and Development<br />

of Specifications for Waste Plastic Modified Hot Mix<br />

Asphalt.<br />

On-going projects reported include application of<br />

Rhinophalt preservative for studying/evaluating<br />

its performance on three toll roads in Rajasthan


and Gujarat states; and design, construction and<br />

performance evaluation of new materials and mixes<br />

towards development and upgradation of standards /<br />

specifications.<br />

2. Geotechnical engineering<br />

The projects reported in the Geotechnical Engineering<br />

area relate to landslide Hazard Mitigation and<br />

Management on <strong>Indian</strong> <strong>Roads</strong> and <strong>Highway</strong>s, Site<br />

Stabilization work, Use of jute geotextiles in PMGSY<br />

roads to study efficacy of Jute Geotextile (JGT) and<br />

utilization of various solid industrial wastes in road works.<br />

Waste materials have been evaluated in the laboratory<br />

as well in the field by constructing experimental test<br />

sections. Performance observations are being taken up.<br />

The issues related with road infrastructure development<br />

in disaster prone areas have also received attention<br />

of researchers. Early warning system for landslides<br />

by simple and economical instrumentation like steel<br />

pedestals and DGPS, design and construction of roads<br />

in submerged/ flood affected areas of Rann of Kutch,<br />

Gujarat, formulation of guidelines for road construction<br />

in such areas have been reported. Design and<br />

construction of embankments in waterlogged areas by<br />

using fly ash, a novel construction methodology involving<br />

back-dumping of pond ash directly into water pond<br />

was also devised. CRRI- GTE Division is developing<br />

a non nuclear, non destructive type of equipment for<br />

determination of dry density of compacted soils.<br />

<strong>Research</strong> work has been performed on soil stabilization<br />

using commercially available materials, use of fly ash,<br />

copper slag, cinder waste, and phosphogypsum in<br />

subgrade and embankment construction. Based on<br />

laboratory data, it was found that in case of all the four<br />

types of soils as mentioned above, the unconfined<br />

compressive strength of soil stabilized with 2, 4 and 6<br />

Per cent cement gives higher strength as compared to<br />

with 2, 4 and 6 Per cent commercial stabiliser for 7, 14<br />

and 28 days curing period. The fly ash, bottom ash and<br />

pond ash samples can be used in embankment and<br />

road works. The study indicated that 10-15 Per cent of<br />

fine aggregate can be replaced by super fine slag. The<br />

optimum bitumen content was obtained as 4.8 Per cent<br />

and 5.5 Per cent respectively for DBM and BC mixes. The<br />

bituminous samples with superfine copper slag satisfied<br />

the design requirements as per MORTH specifications.<br />

A combination of waste recycled products and cinder<br />

can satisfy density requirements of the materials for the<br />

embankment construction. It was observed that both<br />

deflection and roughness characteristics of copper slag<br />

embankment was comparable to soil embankment. By<br />

providing geo-textiles the CBR value of weaker sub<br />

grades could be enhanced. Thereby, the pavement<br />

layer thickness can be considerably reduced and this<br />

facilitates the construction of roads in poor sub-grade<br />

ROAD RESEARCH IN INDIA 2011-12 3<br />

soil areas. SoilTech MK-III- engineered a SSB layer<br />

with much more strength then WMM (a ideal base<br />

course with more than 3000 Mpa strength). SoilTech<br />

MK-III-economized the project substantially. The<br />

ecological contribution of SoilTech MK-III used roads<br />

is excellent and over 50% then the conventional crust<br />

reducing man, machine and material consumption.<br />

3. Bridge engineering<br />

In this Chapter, the projects related to various aspects<br />

of bridges such as structural health monitoring,<br />

techniques for distress diagnostics, effect of corrosion on<br />

performance, remaining life assessment, strengthening<br />

techniques etc. are reported.<br />

Most of these projects are useful for Bridge<br />

Management, consisting of inventorization, condition<br />

assessment of the existing bridge with the help of<br />

inspection or NDTs, distress diagnostics, load carrying<br />

capacity evaluation of existing bridges with the help<br />

of analytical or experimental or a combination of both<br />

considering an appropriate degradation model, loading<br />

and environmental conditions, and choosing a suitable<br />

rehabilitation and strengthening techniques. All these<br />

aspects require in-depth knowledge, expertise as well<br />

as technology for which research is being carried out<br />

at a fast pace. Further, there is an immediate attention<br />

required for effective implementation of BMS in our<br />

country for prioritizing the maintenance of bridges in a<br />

road network.<br />

Indigenous design and development of tool for<br />

inspection of bridges such as Mobile Bridge Inspection<br />

Unit and Creation of Bridge Expansion Joint Test facility<br />

are of great interest to professionals.<br />

Also, the studies to assess the impact of noise and<br />

vibration levels after construction of transportation<br />

structure on built environment, their cause and remedial<br />

measure needs to be well taken at the planning stage<br />

of the infrastructure development.<br />

Network in lavasa to Comply the Pre-Conditions<br />

set by Environmental Impact Assessment Expert<br />

Appraisal Committee, the objective of this study<br />

is to conduct the road safety audit of Dasve road<br />

network in lavasa and suggest the road safety<br />

measures and contingency plans to deal with the<br />

road traffic mishaps/accidents. This study is in<br />

progress.<br />

Measurement of air quality and noise level<br />

at proposed IISER campus at Vithura in<br />

Thiruvananthapuram district was studied and<br />

reported. The aim of the project is to assess the<br />

ambient air quality and noise levels in and around<br />

the proposed IISER construction site as the part<br />

Environmental Impact Assessment (EIA) study.<br />

Study on Micro level Study of Accident Hazards<br />

on National <strong>Highway</strong> <strong>No</strong>. 8 from Amdavad to<br />

Vadodara was reported. This study identified 14<br />

accident prone locations on the stretch and then by<br />

actual site visit of the locations remedial measures<br />

are suggested to minimize the accidents.<br />

Variability in vehicle fuel consumption<br />

under controlled conditions was studied<br />

and reported. In this study variability in<br />

steady speed fuel consumption is up to<br />

8.2 Per cent with the various steady speeds was<br />

identified for both Petrol and Diesel driven light<br />

duty vehicles almost uniform variability in value<br />

of fuel consumption was observed. Optimum fuel<br />

consumption was observed consistently for both<br />

vehicle types to be either at steady speed of 40<br />

or 50 km/h.<br />

Study of <strong>No</strong>n methane hydrocarbons in the<br />

atmospheric environment of Delhi region was<br />

completed. This study shows that the proportion<br />

of propane is highest in traffic area i.e. 98 Per cent<br />

followed by ethane (2 Per cent). Butane shows a<br />

negligible concentration in this area. The study<br />

results show that the only expected source of<br />

propane is traffic in the ambient air. The results


6<br />

show that in residential area also concentration of<br />

ethane is maximum. This could also be attributed<br />

to the lPG leakage in houses. lPG is normally<br />

used in residential areas for cooking purposes.<br />

Residential sampling site like Maharani Bagh<br />

have underground lPG pipelines even any small<br />

leakage during handling and usage can increase<br />

concentration of ethane in ambient air.<br />

5. research Work Done in academic Institutions<br />

related to thesis Work<br />

5.1 pavement engineering and Materials<br />

The research work done under various thesis projects<br />

have concluded the following:<br />

i) Delay in the maintenance application increases<br />

the maintenance cost approximately two times for<br />

every year of delayed maintenance. This leads to<br />

increase in Vehicle operating cost.<br />

ii) Recycled Asphalt Pavement can be partially or<br />

completely reused in fresh construction.<br />

iii) Study of pervious concrete has revealed that<br />

compressive strength of pervious concrete is<br />

<strong>39</strong> Per cent less than normal concrete. Split tensile<br />

strength is 15 Per cent less than normal concrete.<br />

Modulus of rupture of pervious concrete is 22 Per<br />

cent less than normal concrete. The average coefficient<br />

of permeability was found to be 0.155 cm/<br />

sec.<br />

iv) From experiments, Geotextile placed at bottom of<br />

overlay performed better than geotextile placed at<br />

one-third from bottom in the overlay followed by<br />

geotextile placed at middle in the overlay.<br />

v) From the results of aging index, for VG 20 grade<br />

bitumen, lime added at 2 Per cent shows maximum<br />

increase in viscosity after aging process, but<br />

cement added at 1 Per cent has less effect on<br />

viscosity with aging.<br />

vi) For VG 10 grade bitumen, fly ash added at<br />

2 Per cent shows maximum increase in viscosity<br />

after aging process, but lime added at 1.5 Per cent<br />

has less effect on viscosity with aging.<br />

vii) Analysis of the 100 sample database for their<br />

penetration at 25 ºC and viscosity at 60 ºC revealed<br />

that samples having good temperature and shear<br />

susceptibility always had higher penetration for<br />

a given viscosity range. For instance, samples<br />

having R value of 0.9 and above, shows a higher<br />

penetration value of 60 within a viscosity range of<br />

1600-2400.<br />

GENERAl REPORT ON<br />

viii) Fatigue life of SMA mix prepared with PMB 40<br />

was 5.19 Per cent greater than that of SMA mix<br />

prepared with PMB 70.<br />

ix) WMA binder treated with Zycosoil and Densicryl<br />

showed very negligible draindown values. This<br />

indicates that separation of fines and bitumen<br />

noticed during transportation and placing of the<br />

mixture is restricted to a large extent.<br />

x) In pavement design, the application of reliability<br />

methods in pavement design is underutilized,<br />

particularly in codes and design guides that depend<br />

heavily on empirical data and the criterion for<br />

selecting the reliability level is primarily governed<br />

by the importance of the road section. Study<br />

shows the importance of incorporating parametric<br />

uncertainty in the determination of pavement<br />

reliability through the estimation of partial factors,<br />

the drawbacks of assigning such reliability levels<br />

without the explicit consideration of the design<br />

uncertainties is highlighted.<br />

xi) From the lab investigations it was observed that<br />

the temperature of the mix influences the skid<br />

resistance<br />

xii) It was seen that skid resistance under dry and wet<br />

conditions for mixes with added fibers higher than<br />

that of control mix.<br />

xiii) The study shows that although the concept of<br />

perpetual pavements advocates the increase of<br />

HMA thickness to keep the critical strains within the<br />

threshold limits, the provision of a stable foundation<br />

and the high stiffness base materials are equally<br />

significant from a financial perspective.<br />

xiv) The minimum cement content for any pervious<br />

cement concrete is 230 kg/m 3 . Addition of<br />

50 Per cent more cement content resulted<br />

in a minimum of 66 Per cent increase in the<br />

compressive strength. The lowest compressive<br />

strength exhibited is 5.67 N/mm 2 .<br />

xv) By decreasing the height of the soil above the<br />

tunnel, the surcharge pressure coming over the<br />

tunnel decreases, but if a road comes over a tunnel<br />

due to the reduction of soil thickness above the<br />

tunnel, wheel loads has more significance.<br />

•<br />

•<br />

Improvement of available materials and mixes for<br />

various layers of pavements<br />

Determination of mechanistic properties of modified<br />

materials and mixes<br />

Methodology<br />

Firstly various laboratory testing such as fatigue test,<br />

resilient modulus, static creep etc, will be done to see the<br />

improvement in the mechanistic properties of modified<br />

materials and mixes for various layers of pavements.<br />

Based upon above laboratory test results mechanistic<br />

analysis will be performed to check the scope for<br />

reduction of thickness based upon critical strains value.<br />

Finally validation of proposed new structure will be<br />

done with the help of APTF facility and producing the<br />

results in the form of new design templates.<br />

Interim Conclusions/Conclusions/Supporting Data<br />

•<br />

•<br />

•<br />

•<br />

Polymer modified binder improve the tensile<br />

strength of the bituminous mix under dry and moist<br />

conditions. Modified mix also has higher retained<br />

Marshall Stability and tensile strength ratio, which<br />

indicates improved resistance towards moisture<br />

susceptibility.<br />

The Creep Modulus of Modified mix indicates<br />

improved rut resistance of modified pavement<br />

at higher pavement temp. Utilization of modified<br />

bitumen in bituminous layer reduces the permanent<br />

deformation by 45 Per cent, 60.5 Per cent and<br />

74.4 Per cent at 25, 35 and 45°C temperature.<br />

The final rut achieved in slabs made with PMB<br />

40 binder indicates lower rutting susceptibility of<br />

modified mix as compared to unmodified mix made<br />

with VG 30 binder.<br />

The phase angle of unmodified mix is about<br />

20 Per cent higher as that of modified mixture<br />

which leads to more dissipation of energy during<br />

flexural fatigue test and finally less resistance to<br />

fatigue failure.<br />

Scope and Objectives<br />

The scope and objective of the project focuses on the<br />

utilization of tannery solid waste as an ingredient in the<br />

formulation of road construction materials (road). The<br />

main objective includes:<br />

iii Analysis of test results and submission of<br />

research report.<br />

Significance/ utilization Potential<br />

Every 100 tons of leather generate 2.5-3.5 tons of CS<br />

as waste, which is currently under utilized for leather<br />

board making or widely wasted in the name of landfill<br />

which ultimately pollutes the soil as well as ground<br />

water owing to its chromium content. Since, this project<br />

proposes to utilize CS as filler in bituminous mix for<br />

road construction, the disposal problem of CS will be<br />

solved. Secondly, the CS upon mixing with bitumen,<br />

gets embedded or encapsulated and hence its contact<br />

with water is prevented and therefore, the chances of<br />

leachability of chromium is more unlikely.<br />

This apart, the use of CS in bitumen mix replaces the<br />

sand to certain level which to some extent prevents<br />

the sand quarrying and thereby restores the natural<br />

resources. Moreover, the waste material CS, when<br />

finds new application its collection and processing<br />

would provide opportunity for new industry, more<br />

employments. Additionally, the waste would bring<br />

added revenue to the tanning industry. Hence, this<br />

project will have potential impact on the development<br />

of society, economy and environment.<br />

Limitations of Conclusions/ further proposed work<br />

Apart from utilizing waste for social, economic and<br />

environmental benefit, the following outputs are<br />

expected in this project.<br />

i. Publication<br />

present Status and progress<br />

Status : On-going<br />

A comprehensive database with quantum and quality<br />

of the resources available along with their engineering<br />

properties and suitability to various construction<br />

activities are prepared. A detailed database regarding<br />

the resource locations distributed within the district is<br />

prepared with attribute data containing the physical<br />

and engineering properties of the resources, geo<br />

coordinates, photos and bitmaps showing the<br />

accessibility of resource locations. Similar work is being<br />

done for other districts in Kerala.<br />

GENERAl REPORT ON<br />

Further Findings/Conclusions/Supporting Data<br />

In the case of coarse aggregate, most of the samples<br />

tested have desirable values of Specific Gravity, Water<br />

absorption, Bulk density and Aggregate Impact Value.<br />

As regards to the shape of the coarse aggregates, higher<br />

values is obtained for the combined index for majority<br />

of samples showing their unsuitability for construction<br />

purpose when compared with the present MORTH<br />

specifications. This calls for a thought on the need for<br />

revision of the current specification of combined index<br />

values. The properties of the fine aggregate lies within<br />

the values stipulated for construction. For few of the<br />

aggregates, some of the engineering properties are<br />

beyond the desired limits and hence their suitability to<br />

various types of construction works is assessed.<br />

recommendations for further Work<br />

Similar work can be done for other districts within<br />

the state and within the country so that suitability of<br />

the resources and their locations can be determined.<br />

This research work can be extended and stepped to<br />

more resources and their locations so that the use<br />

of locally available materials can be enhanced and a<br />

database can be created on their performance and cost<br />

effectiveness for adoption in road construction in a big<br />

way. <strong>Research</strong> can also be extended to investigate the<br />

possible effects of shape of the aggregates on other<br />

aggregate properties.<br />

Further Findings/ Conclusions/Supporting Data<br />

The careful study of the field data collected during the<br />

periodic observations indicated that the deflection, the<br />

total distress and the serviceability index over a period of<br />

time are minimal in Geotextile test sections as compared<br />

to the control panel. Since all the above parameters are<br />

measure of the performance and structural capacity<br />

of road pavement, the results clearly indicate that the<br />

inclusion of a Geotextile can improve the performance<br />

of the road pavement possibly due to its ability to<br />

reinforce and strengthen the pavement and to control<br />

the degradation of structural behavior of pavement as<br />

compared to pavement without Geotextile.<br />

Significance and utilization potential<br />

ASPHAlTOSEAl is a bitumen pad consisting of a high<br />

strength, heat resistance with reinforcement in APP<br />

Modified Asphalt. The roll is supplied in thickness of<br />

3 mm.<br />

ASPHAlTOSEAl bitumen pad has been specifically<br />

designed to waterproof concrete structures that<br />

utilize and Asphaltic Concrete Wearing Surface<br />

such as on Bridges, overpasses and parking decks.<br />

ASPHAlTOSEAl bitumen pad protects the concrete<br />

structure from the corrosive affects of decicing salts.<br />

ASPHAlTOSEAl bitumen pad has been uniquely<br />

formulated to perform under the most demanding<br />

conditions. The mesh strengthens and reinforces the<br />

system. The mesh and rubberized asphalt interact to<br />

form a tough pad that remains flexible through a wide<br />

range of temperature and substrate movements. The<br />

tacky rubberized asphalt assures quick adhesion to<br />

the concrete deck. Asphaltic concrete will flow into<br />

the mesh when the asphalt mix is compacted on<br />

laid asphalt at the minimum temperature of 135 o C<br />

(275 o F). The asphalt does not require any protection<br />

system when applied under asphalt wearing course.<br />

ASPHAlTOSEAl bitumen pad provides good bonding<br />

and a homogeneous waterproof layer between the<br />

Concrete Deck and the asphaltic concrete overlay.<br />

Full adhesion of the Mastic Pad to the concrete deck<br />

GENERAl REPORT ON<br />

prevents water migration below. ASPHAlTOSEAl is<br />

manufactured to stringent quality standards (ASTM D<br />

622), and is delivered ready to apply by thermofusion.<br />

Another unique advantage is the ability of<br />

ASPHAlTOSEAl to self-seal. The pad can be applied<br />

over active cracks, less than 6 mm in width without<br />

any tapping of the crack or special preparation.<br />

ASPHAlTOSEAl will withstand foot traffic and light<br />

construction traffic immediately after installation. Paving<br />

can commence as soon as ASPHAlTOSEAl is laid.<br />

1. Investigation of Causes of Longitudinal<br />

Cracking in Concrete Pavements on National<br />

<strong>Highway</strong>s<br />

Date of Start : June 2012<br />

Date of completion : March 2013<br />

CSIR – Central Road <strong>Research</strong> Institute, New<br />

Delhi-110 025 (R)<br />

Scope & Objective<br />

Concrete pavements at many locations have been<br />

constructed in the last 8-10 years under NHDP.<br />

These concrete pavements have been designed and<br />

constructed for the design life of 25-30 years. The<br />

structural failure at some of these concrete highways,<br />

for examples Indore By-pass, Kanpur-Allahabad,<br />

Balasore-Orissa, Chittorgarh – Mangalwar, have<br />

occurred because of full depth longitudinal cracking. A<br />

thorough investigation of causes of longitudinal cracking<br />

is urgently required to help built better concrete roads<br />

in future. The objective of the project is to carry out<br />

detailed investigation and possible ways of avoidance<br />

of such cracking.<br />

Methodology<br />

The investigation will be carried out by taking concrete<br />

cores over the longitudinal joints and cracks to measure<br />

the in-situ strength of concrete, to measure the depth of<br />

saw cut and crack. Surface strain gauges will be used to<br />

measure dynamic strain induced at the top of concrete<br />

slabs under traffic loads. Axle load survey and traffic<br />

survey will be conducted and the data will be utilized<br />

for stress – strain analysis.<br />

Significance/ utilization Potential<br />

Premature failure, as has happened at the location of<br />

the proposed project, of concrete pavements which<br />

are expected to provide long lasting durable roads,<br />

is a major concern for the development of such<br />

pavements in the country. The findings of the project<br />

will help the agencies involved in the development of<br />

highways especially that of concrete to take care in<br />

future construction of such pavements that will not fail<br />

prematurely.<br />

2. Utilization of Waste Foundry Sand in Pavement<br />

Quality Concrete and Dry Lean Concrete<br />

Date of Start : August 2012<br />

Date of completion : August 2014<br />

CSIR – Central Road <strong>Research</strong> Institute, New<br />

Delhi-110 025 (R)<br />

Scope & Objective<br />

Foundry sand is a waste of foundry industries. The<br />

objectives of the study are:<br />

I. To evaluate the engineering properties of foundry<br />

sand<br />

II. To evaluate the properties of Pavement Quality<br />

Concrete (PQC) and Dry lean Concrete (DlC)<br />

mixtures prepared with foundry sand as partial<br />

replacement of natural sand.<br />

III. To develop the methodology of possible beneficial<br />

use of foundry sand in PQC and DlC mixes for<br />

road construction.<br />

Methodology<br />

Foundry sand will be collected from metal casting<br />

industries. Engineering properties like gradation,<br />

fineness modulus, water absorption, specific gravity,<br />

strength etc. of all the materials including foundry sand<br />

will be tested in the laboratory. Control concrete mixes<br />

for PQC and DlC will be designed for two-three different<br />

water –cement ratios using natural sand/crushed stone<br />

dust as fine aggregate. Different amounts of foundry<br />

sand then will be used as partial replacement of fine<br />

aggregate used in the control mixes. Samples will be<br />

prepared in the laboratory with different contents of<br />

foundry sand at all the water-cement ration. Samples<br />

will be tested for various properties of concrete like<br />

compressive and flexural strength, drying shrinkage,<br />

abrasion resistance etc. Based upon the analysis of<br />

test results, the feasibility and extent of using foundry<br />

sand in concrete will be determined.<br />

Significance/ utilization Potential<br />

The study will lead to possible innovative utilization of<br />

foundry sand in construction of concrete roads apart<br />

from its present use in land fill application. The use<br />

of waste foundry sand, if could be feasible, will not<br />

only provide for its better utilization but also will help<br />

in conserving the precious natural resource of natural<br />

sand.<br />

II. GEOTECHNICAL ENGINEERING<br />

SUMMarY<br />

The projects reported in the Geotechnical Engineering area relate to landslide hazard mitigation, Guidelines on<br />

landslide Management on <strong>Indian</strong> <strong>Roads</strong> and <strong>Highway</strong>s, Site Stabilisation work, Use of jute geotextiles in PMGSY<br />

roads to study efficacy of Jute Geotextile (JGT) and utilization of various solid industrial wastes in road works. Waste<br />

materials have been evaluated in the laboratory as well in the field by constructing experimental test sections.<br />

Performance observations are being taken up. The issues related with road infrastructure development in disaster<br />

prone areas have also received attention of researchers. Design and construction of roads in submerged/ flood<br />

affected areas of Rann of Kutch, Gujarat, formulation of guidelines for road construction in such areas have been<br />

reported. A project on equipment development for determination of dry density of compacted soils (<strong>No</strong>n nuclear, <strong>No</strong>n<br />

destructive type) has also been reported.<br />

A test section was laid using Jarofix, a waste of zinc metallurgical industry. It has been concluded that mixture<br />

of jarofix and soil can be used for embankment and subgrade construction. Utilization of laterite stone is being<br />

investigated for road construction in Ratnagiri District of Maharashtra. Data management and information system,<br />

landslide mitigation measures, road user cost models and bridge maintenance and management system has been<br />

developed.<br />

<strong>Research</strong> work has been performed on soil stabilization using commercially available materials, use of fly ash, copper<br />

slag, cinder waste, and phosphogypsum in subgrade and embankment construction. Based on laboratory data, it<br />

was found that in case of all the four types of soils as mentioned above, the unconfined compressive strength of soil<br />

stabilized with 2, 4 and 6% cement gives higher strength as compared to with 2, 4 and 6% commercial stabiliser for<br />

7, 14 and 28 days curing period. The fly ash, bottom ash and pond ash samples can be used in embankment and<br />

road Works. The study indicated that 10-15% of fine aggregate can be replaced by super fine slag. The optimum<br />

bitumen content was obtained as 4.8% and 5.5% respectively for DBM and BC mixes. The bituminous samples<br />

with superfine copper slag satisfied the design requirements as per MORTH specifications. A combination of waste<br />

recycled products and cinder can satisfy density requirements of the materials for the embankment construction. It<br />

was observed that both deflection and roughness characteristics of copper slag embankment was comparable to<br />

soil embankment. By providing geo-textiles the CBR value of weaker sub grades could be enhanced. Thereby, the<br />

pavement layer thickness can be considerably reduced and this facilitates the construction of roads in poor subgrade<br />

soil areas. SoilTech MK-III- engineered a SSB layer with much more strength then WMM (a ideal base course<br />

with more than 3000 Mpa strength). SoilTech MK-III-economized the project substantially. The ecological contribution<br />

of SoilTech MK-III used roads is excellent and over 50% then the conventional crust reducing man, machine and<br />

material consumption.<br />

Scope and Objectives<br />

lukhbir slide is located at km 26.8 on NH 31- A.<br />

This landslide is active since 1968. Border <strong>Roads</strong><br />

Organisation sponsored this study undertaken by<br />

CSIR-CRRI for design of suitable remedial measures.<br />

Methodology<br />

The rocks found at lukhbir slide area, are in highly<br />

weathered condition. Although these rocks dip away<br />

in to the hills from the roadway, at an angle of nearly<br />

40-45°, due to highly weathered conditions they are<br />

vulnerable to failure. Sometimes, rocks are found in<br />

the form of powder due to excess overburden pressure<br />

and ingress of moisture. Rocks here occur in very thin<br />

layered form, but seem to be compacted probably again<br />

due to the overburden. There are traces of fractures on<br />

the weathered rock surface in different directions. The<br />

slope has plenty of seepage water which makes the<br />

slope vulnerable to failure.<br />

Interim Conclusions/Conclusions/Supporting Data<br />

For stabilising the downhill slope the following remedial<br />

measures were designed:<br />

•<br />

•<br />

•<br />

•<br />

•<br />

Design of gabion wall on downhill slope<br />

Design of 15m high cantilever wall on downhill<br />

Scope and Objectives<br />

Stabilisation of Hill-Cut Slope at <strong>No</strong>rth Andaman Island<br />

(Near Diglipur) using appropriate landslide remediation<br />

measure<br />

Methodology<br />

The area under the study falls in the <strong>No</strong>rthern Part of<br />

Andaman Islands. Diglipur is the main township of the<br />

<strong>No</strong>rth Andaman Island, which is about 325 km from<br />

Port Blair. Most of the hill ranges in these islands,<br />

show a parallel trend to each other. The Platform was<br />

constructed after cutting two adjoining hillocks. The<br />

hilltop is at an elevation of 148m from mean sea level.<br />

The terrain is fully covered with dense vegetation.<br />

Nearly 3.5 lakhs cubic meters of earth was excavated<br />

to create platforms on the hilltop. Debris excavated from<br />

that area was loosely dumped on side slopes. Berms<br />

were provided on the slope. These hill cut platforms<br />

now face instability problems due to landslides. Heavy<br />

rainfall during monsoon contributes to slope stability<br />

problems in this area. The first landslide was observed in<br />

one side of the hill cut platform during September 2008.<br />

Presently another slide has occurred in the opposite<br />

side of the first slide. MES authorities requested CRRI<br />

to investigate and suggest Slope Stabilisation and<br />

other remedial measures. The field investigations are<br />

in progress.<br />

Interim Conclusions/Conclusions/Supporting Data<br />

The project is presently under progress.<br />

Significance/ Utilisation Potential<br />

The instability problems have occurred mainly due to<br />

(a) Highly weathered and soft nature of rocks in the<br />

ROAD RESEARCH IN INDIA 2011-12 33<br />

area and (b) Creation of additional overburden pressure<br />

due to dumping of hill cut materials (c) High rainfall and<br />

inadequate drainage measures which saturate the<br />

landmass<br />

7. Feasibility Study of a patented Commercial<br />

soil stabiliser<br />

Keywords: Soil stabilisation, silt and Clay<br />

Date of Start: Feb. 2011<br />

Date of Completion: March. 2012<br />

CSIR- Central Road <strong>Research</strong> Institute, New<br />

Delhi (R)<br />

Scope and Objectives<br />

•<br />

•<br />

To investigate the efficacy of a commercial soil<br />

stabiliser for stabilization of different types of soils<br />

used in road construction.<br />

To carry out this study on four types of soils -<br />

Coarse grained soils (Badarpur sand and Granular<br />

sub base soil) and fined grained soils (Delhi silt and<br />

Clayey soil).<br />

Methodology<br />

In order to assess the efficacy of Patented commercial<br />

Stabiliser via-a-vis Cement (a conventional soil<br />

stabilizer), two types of coarse grained soils (Badarpur<br />

sand and Granular sub base material) and two types<br />

of fine grained soils (Delhi silt and Clayey soil) were<br />

stabilized both with cement and commercial soil<br />

stabilizer separately. Strength gain was determined in<br />

terms of Unconfined compressive strength and CBR.<br />

The durability tests were also conducted to assess the<br />

performance of stabilized soils under the wetting and<br />

drying cycles which simulate the environment condition<br />

in field.<br />

Interim Conclusions/Conclusions/Supporting Data<br />

Based on laboratory data, it was found that in case<br />

of all the four types of soils as mentioned above, the<br />

unconfined compressive strength of soil stabilized<br />

with 2, 4 and 6% cement gives higher strength as<br />

compared to with 2, 4 and 6% commercial stabiliser<br />

for 7, 14 and 28 days curing period. The increase in<br />

soaked CBR value with 2%, 4% and 6% cement and<br />

commercial stabiliser was also evaluated. It was found<br />

that CBR values increase significantly with the addition<br />

of both cement as well as commercial stabiliser. From<br />

durability test, it was concluded that silty soil sample<br />

stabilized with 2% Cement as well as commercial<br />

stabiliser failed, indicating necessity for higher dosage<br />

of stabiliser. Accordingly, Delhi silt stabilised with 4 and<br />

6% cement and commercial soil stabilizer, satisfied<br />

durability test criteria as stipulated in ASTM D559 and<br />

in IRC :SP:98-2010. In case of Badarpur sand samples<br />

stabilized with 2%, 4% Cement and 2%, 4% and 6%<br />

commercial stabiliser failed in durability test. However,<br />

Badarpur sand sample stabilized with 6% Cement<br />

ROAD RESEARCH IN INDIA 2011-12 35<br />

could pass the durability test. In case of clayey soil the<br />

samples made with both cement as well as commercial<br />

stabiliser could not satisfy the criterion as stipulated<br />

in ASTM D559 and prescribed by IRC: SP:98-2010.<br />

However in case of Granular soil it was concluded that<br />

soil sample stabilized with 2%, 4% and 6% Cement as<br />

well as 2%, 4% and 6% commercial stabiliser could<br />

pass the durability test.<br />

Significance/ Utilisation Potential<br />

Based on laboratory studies, it was concluded that<br />

Delhi silt treated with both 4 and 6% cement as well<br />

as commercial soil stabilizer, Badarpur sand with 6%<br />

cement only and granular soil with 2%, 4% and 6%<br />

cement as well as commercial soil stabilizer, can be<br />

considered for its use for subgrade improvement as<br />

well as in sub-base layer of a road pavement. However,<br />

before recommending for large scale application, an<br />

experimental section be constructed and monitored<br />

over a period of time to assess the performance of<br />

road.<br />

Scope and Objectives<br />

To assess the suitability of locally available granular<br />

materials, locally known as Tibba sand for the<br />

construction of embankment, sub grade and capillary<br />

cut-off.<br />

Methodology<br />

A stretch of about 4.2 km length of NH-71 near Jhajjar<br />

in Haryana experiences frequent failures due to low<br />

embankment height of the road and presence of an<br />

canal adjacent to this road at this location. The subgrade<br />

soil of this road gets saturated and subsequently it<br />

results in failure. The water from canal saturates the<br />

sub grade layer by capillary action. To rectify this<br />

problem, it was decided that the height of embankment<br />

be raised and a capillary cut-off layer be provided. For<br />

this, locally available materials commonly known as<br />

Tibba sand and GSB materials were investigated for the<br />

construction of embankment, sub grade and capillary<br />

cut-off. It was observed that Tibba sand may be used<br />

for the construction of embankment and a mix of Tibba<br />

sand and soil can be used for sub grade construction.<br />

Interim Conclusions/ Supporting Data<br />

Granular materials, available locally, did not satisfy the<br />

required filter/drainage specifications for capillary cut-<br />

Scope and Objectives<br />

In order to assess suitability of Phosphogypsum as a<br />

road construction material, a laboratory study has been<br />

taken up. The broad scope of work is as follows:<br />

•<br />

•<br />

•<br />

•<br />

Characterization of Phosphogypsum<br />

Characterization of locally available Soil /Fly ash<br />

and Phosphogypsum mixes<br />

Use of Phosphogypsum in concrete roads<br />

Use of Phosphogypsum in Bituminous mixes of<br />

flexible pavements.<br />

Methodology<br />

To carry out the study, Phosphogypsum samples<br />

and locally available soil was collected. The locally<br />

available soil is fine grained soil and clayey in nature.<br />

Since fly ash is available in plentiful nearby, mixes of<br />

phosphogypsum and fly ash at various proportions have<br />

also been characterised. Physical and engineering<br />

properties of phosphogypsum as such and mixes of<br />

Phosphogypsum and soil/ fly ash have been determined<br />

in CRRI laboratory. The properties determined include<br />

specific gravity, particle size distribution, consistency<br />

limits such as liquid limit and Plastic limit, OMC and<br />

MDD, etc. The strength and engineering characteristics


38<br />

of phosphogypsum alone and in combination with local<br />

soil, lime and fly ash, etc were determined in terms of its<br />

Shear strength (c, φ) and California Bearing Ratio (CBR).<br />

In order to assess the efficacy of phosphogypsum for<br />

the purpose of stabilisation, mechanical stabilization<br />

of soil and phosphogypsum and lime stabilization of<br />

phosphogypsum has been carried out separately and<br />

strength gain was determined in terms of Unconfined<br />

Compressive Strength and California Bearing Ratio<br />

(CBR). The durability tests were also conducted to<br />

assess the performance of stabilized soils when<br />

subjected to wetting and drying cycles.<br />

Interim Conclusions/ Supporting Data<br />

Based on laboratory data, it was found that<br />

phosphogypsum as such when compacted at OMC &<br />

MDD, has very good shear strength. The unconfined<br />

compressive strength (UCS) was good enough for<br />

its use in different pavement layers. However when<br />

this sample was soaked in water for the purpose of<br />

durability, it was found to lose some strength but still<br />

it has sufficient strength for use in sub base layer or<br />

as a capping layer. The local soil was stabilized with<br />

different percentages of phosphogypsum going upto<br />

50%. The gain in strength was determined in terms of<br />

Unconfined Compressive Strength. It was found that<br />

with the addition of phosphogypsum, the UCS increased<br />

but only upto 20% of phosphogypsum addition. When<br />

the quantity of phosphogypsum was increased beyond<br />

20%, UCS strength decreased. However, when the<br />

mixes of soil and phosphogypsum, were subjected to<br />

durability tests none of the samples could withstand<br />

the durability test criteria. During the determination of<br />

unconfined compressive strength, it was observed that<br />

compacted specimen of phosphogypsum behaved like<br />

a semi rigid material.<br />

Significance/ Utilisation Potential<br />

Based on laboratory studies, it is concluded that<br />

phosphogypsum as such can be used as a fill material<br />

and in sub-grade/sub-base layer of a road pavement.<br />

However, before recommending for large scale<br />

application, an experimental section be constructed<br />

and monitored over a period of time to assess the<br />

performance of road. Further work is currently under<br />

progress.<br />

copper slag was carried out as per the methodology<br />

developed by CRRI. The embankment was constructed<br />

in the bridge approaches of Madurai-Tuticorin <strong>Highway</strong><br />

(NH-45B). The approaches towards Madurai (200m<br />

on both lanes) were constructed with copper slag<br />

while the approach towards Tuticorin (200m) was<br />

constructed with soil. The maximum height of copper<br />

slag embankment was 4m. Copper slag is sand<br />

sized cohesionless material, hence construction of<br />

embankment using copper clag alone is not feasible.<br />

Hence Copper slag was mixed with locally available<br />

pond ash in equal proportion and embankment was<br />

successfully constructed. Copper slag which was<br />

found suitable as a replacement of fine aggregates in<br />

bituminous construction, was tried for its field usage, by<br />

constructing a 350m length experimental Bituminous<br />

concrete layer. The first performance observation of<br />

experimental test section of copper slag embankment<br />

and bituminous concrete layer has been recorded.<br />

Roughness, rutting and deflection of the test track<br />

was noted using different equipment, viz. Benkelman<br />

beam, dip stick and Total station. Bituminous core was<br />

taken from the surface layer of bituminous concrete<br />

constructed by using copper slag to evaluate its in-situ<br />

density.<br />

Interim Conclusions/ Supporting Data<br />

It was observed that both deflection and roughness<br />

characteristics of copper slag embankment was<br />

comparable to soil embankment.


Significance/ Utilisation potential<br />

Based on laboratory studies, it is concluded that the<br />

copper slag mixed with locally available pond ash by<br />

50 per cent was found suitable as a road construction<br />

material, especially for embankment construction.<br />

Further Findings/ Supporting Data<br />

This project has been taken up as a network project<br />

coordinated by SERC, Chennai. Preparation of<br />

Guidelines for Cyclone prone areas and studies on two<br />

large landslide affected areas were carried out under<br />

this project. Under the second project, two landslides<br />

namely Patalganga and Kaliasaur landslides have<br />

been selected for detailed investigations under this<br />

project.<br />

Work done on Kaliasaur landslide:<br />

1. Base Map Preparation: A total 231.49 Ha area<br />

was covered for the topographical survey with<br />

scale of 1:500. The topographic base map which<br />

was produced with the help of high precision total<br />

station and the DGPS was used to develop a<br />

Digital terrain model and its derivatives maps such<br />

as slope and aspects. The DTM and its derivatives<br />

give opportunity of logical thinking about the<br />

possible influence and activities on the basis of<br />

visual observation on the ground.<br />

Geomorphological Assessment:<br />

Geomorphological studies of the area have been<br />

carried out on the base map of the 1:500 scale.<br />

The morphology of slide has changed regularly<br />

since the slide first appeared. Repeated sliding<br />

of minor magnitude have been occurring from<br />

the main scarp of the slide making the slide<br />

retrogressively moved because the surface of<br />

rupture was extending in the direction opposite the<br />

movement of the displaced material. However, at a<br />

later date the surface of rupture started extending<br />

at the lateral margin as well widening the slide<br />

making it advancing in nature. The cliff, the steep<br />

rupture surface of the top has got enlarged by 40m<br />

since 1984. In 2010 alone it has got enlarged by<br />

20 m during one event of sliding. The cliff between<br />

the crown and displaced material become irregular<br />

because of the numerous gullies. There are many<br />

cracks above the crown part. Below the main scarp<br />

there are a few minor scarp developed, indicating<br />

successive sliding.<br />

Investigating the Role of Geology in Slope<br />

Instability: Detailed geological map of the area<br />

was prepared to find out the role played by<br />

lithology and structures to affect the slope stability.<br />

The independent geology and structural mapping<br />

revealed the fact that structures are formed by<br />

tectonic deformations in past geological times. The<br />

detailed study of major and minor structures was<br />

carried out with an intention of figuring out their role<br />

in inducing instability and causing the slope failures<br />

in the area. In the area of study it has been observed<br />

that contacts between two litho-units (e.g. pink and<br />

white quartzite) are often a fault, i.e. their contact<br />

surface is actually faulted. Prominent foliation of<br />

the area shows that the strata are folded synclinally<br />

and anticlinally. Wedge failure is the most common<br />

mode of failure in highly jointed quartzite rock in<br />

this area.<br />

In a similar manner, Micro-Zonation Analysis Based<br />

on Rock Mass Rating (RMR) and Slope Mass Rating<br />

(SMR), Kinematic Slope Stability Analysis, Microhazard<br />

evaluation has been carried out for this slide.<br />

The landslide activity reactivated during Sep-Oct 2010<br />

and NH 58 had to be closed to traffic and vehicles had to<br />

take a longer detour. CRRI has carried out estimation of<br />

indirect landslide losses due to reactivation of Kaliasaur<br />

landslide using unit cost estimation method.<br />

Detour cost = (Extra operating costs in detouring +<br />

Extra fuel used * Fuel price) * Number of travelers<br />

affected.<br />

The estimation was based on traffic affected due to<br />

detouring due to blockage of National <strong>Highway</strong>–58.


40<br />

The total detouring cost for 45 days during September-<br />

October, 2010 has been estimated to be about Rs. 25<br />

million(approx).<br />

Road construction adjacent to sea – in tidal areas<br />

Methodology<br />

The National Buildings Construction Corporation has<br />

taken up certain road works in Rann of Kutch, Gujarat.<br />

In the Rann of Kutch area, due to flat terrain of the<br />

land, Arabian Sea water transgresses and regresses<br />

frequently leaving inland marshy and swampy, dotted<br />

with small to very large salt water bodies. CRRI team<br />

carried out extensive field work, recording the damages<br />

to embankment and road pavement, site conditions<br />

and after analysis of data, design of erosion control<br />

measures was carried out. The remedial measures<br />

broadly comprise of energy dissipation armour system<br />

of gabions and geotextiles to prevent loss of fill material.<br />

To undertake road embankment construction in<br />

waterlogged stretch, use of granular material has been<br />

suggested. Presently road embankment construction<br />

is under progress using back dumping technique<br />

and granular materials in water. Basal reinforcement<br />

using geogrids has been provided to facilitate road<br />

construction in tidal areas.<br />

Scope and Objectives<br />

The Government of Delhi has entrusted construction<br />

of Signature Bridge and its approaches at Wazirabad<br />

across River Yamuna to Delhi Tourism & Transportation<br />

Development Corporation ltd. (DTTDC). The eastern<br />

approach of this bridge comprises of an embankment of<br />

about 1.8 km length and a flyover over the embankment<br />

at the intersection. During September 2008, flooding<br />

of the Yamuna basin occurred due to torrential rains.<br />

A part of the stretch in which embankment is to be<br />

constructed, was still submerged in water (2 to 2.5 m<br />

deep) even in March 2009. DTTDC approached CRRI<br />

to provide ‘Design and Construction Methodology for<br />

approach embankment in water logged area’. The road<br />

embankment construction is now nearing completion<br />

based on CRRI design and construction methodology.<br />

Methodology<br />

CRRI team carried out detailed field investigations<br />

including static cone penetration (SCP) tests at the<br />

proposed site to obtain a clear picture of sub-soil<br />

strength profile. Samples of proposed fill materials like<br />

pond ash, local soil and Yamuna sand were collected<br />

and these were subjected to various tests to determine<br />

their physical and engineering properties. The stability<br />

analysis for the approach embankment was carried<br />

out using the stability analysis software available in<br />

CRRI. The stability analysis showed that embankment<br />

side slope of 1V:2.5 H with a berm of 4 m width to be<br />

provided at a height of 4 m from ground level would<br />

be the most appropriate choice. A novel construction<br />

methodology involving back-dumping of pond ash<br />

directly into water pond was also devised. DTTDC have<br />

now taken up construction of embankment in water<br />

pond area. Presently the construction of embankment<br />

from chainage0.00m-1000m and guide bund at ch:0.00<br />

is nearing completion.

work has been completed, have now been taken up<br />

for performance monitoring. The objective of the<br />

project is to study efficacy of Jute Geotextile (JGT) for<br />

drainage, erosion control, capillary cut-off and subgrade<br />

improvement and hence performance monitoring<br />

forms an important component of this project. Each<br />

of these PMGSY <strong>Roads</strong>, comprise of several subsections<br />

in which JGT of different varieties (woven,<br />

non woven and open weave), of different strengths<br />

and rot treated as well as non treated varieties have<br />

been laid to study their relative performance. Control<br />

sections without JGT have also been constructed.<br />

A distinguishing feature of these test roads is the<br />

construction of reduced pavement thickness sections<br />

where in JGT as drainage improvement layer has been<br />

laid above subgrade. During last year, Second cycle of<br />

visual condition survey of the test sections, recording<br />

of various types of distress in the pavement, shoulder<br />

obtained with the use of coir geotextiles were found<br />

out. It is proposed to lay test tracks and canal bank<br />

protection using biodegradable geotextiles like coir.<br />

The performance of the same will be monitored and<br />

evaluated.<br />

Further Findings/Conclusions/Supporting Data<br />

By providing geo-textiles the CBR value of weaker sub<br />

grades could be enhanced. Thereby, the pavement<br />

of the pavement, are less than the limiting strain<br />

values given by the performance criteria adopted in the<br />

guidelines. limiting strain criteria have been given in<br />

IRC: 37 for two distresses: - rutting along wheel paths<br />

and fatigue cracking in bituminous layers. <strong>No</strong> separate<br />

criterion is available for rutting in bituminous layers. The<br />

GENERAl REPORT ON<br />

criteria for rutting and fatigue cracking in bituminous<br />

layers are given as Equations 1 and 2 respectively.<br />

There after the highway stretch had been constructed<br />

with an over strength Nano Polymer Base liquid called<br />

SoilTech MK-III, as a composite SSB (Soil Stabilized<br />

Base) layer. While calculating the stress/strain failures<br />

in layer Theory formulated in IRC: 37 for this crust, it<br />

was found the reduced crust itself is more than enough to<br />

take 9 CBR & 6 MSA design over a period of 15 years.<br />

Interim Conclusion<br />

a) The usage of Nano Polymer base SoilTech MK-III<br />

has been optimized at 0.5 to 0.55% by weight of<br />

Mix to be stabilized for cost effective SSB layer. In<br />

case, soil criteria don’t suit, then additional blending<br />

of material recommended.<br />

b) The Geotechnical Characteristics, laboratory<br />

results and field in-situ results of many type of soil<br />

stabilization are available. It is now time to evaluate<br />

the standard of each based on Strength, Durability<br />

and Ease of Application. The outcome results of<br />

SoilTech MK-III is substantially higher than any<br />

other stabilizer and as it is used in OMC Ratio with<br />

water to be pulverized, the ease of application and<br />

misuse in this case is zero.<br />

c) Performance of real time traffic stimulation for<br />

last six (06) month shows that ; this SSB layer in<br />

construction enhances the pavement life and also<br />

minimizes the maintenance cost of pavement.<br />

d) Alternate composite design and pavement save<br />

Time and enable first construction.<br />

e) SoilTech MK-III- Engineered a SSB layer with<br />

much more strength then WMM (A IDEAl<br />

BASE COURSE WITH more than 3000 Mpa<br />

strength). SoilTech MK-III-Economized the project<br />

III. BRIDGE ENGINEERING<br />

SUMMarY<br />

Bridge management consists of inventory, condition assessment with inspection or NDTs, distress diagnostics, load<br />

carrying capacity evaluation of existing bridge, prioritization and strengthening and rehabilitation. All these demand<br />

appropriate knowledge as well as technology for which research in our country is going on in a fast pace. Some of the<br />

research projects reported here in highlight the analytical and experimental studies. Also, in this context, field study<br />

of a PSC girder bridge including the rehabilitation scheme is presented.<br />

Health monitoring using smart materials, damage prognostics and mitigation are also interesting fields of study.<br />

Experimental Modal Analysis is being extensively used worldwide for distress diagnostics. Studies on fatigue remaining<br />

life assessment of bridge structures are also of great interest. Developing theoretical capability and assessing efficacy<br />

of different rehabilitation and strengthening techniques for bridge and its components using external prestressing or<br />

wrap methods (CFRP etc) is also another field of research. Understanding the process of material degradation due<br />

to chloride attack, carbonation, ASR etc, under aggressive environmental condition is ongoing research interest.<br />

Also, establishing the efficacy of mitigating efforts such as steel reinforcement with different anti-corrosive coatings in<br />

normal concrete or use of materials such as HPC with uncoated reinforcement is a need of hour.<br />

The impact of noise and vibration in congested urban built environment is another important issue. For example,<br />

noise and vibrations were enhanced in vicinity of a flyover due to movement of heavy vehicular traffic over it, causing<br />

intolerable conditions for residents in the nearby buildings. Assessment of noise and vibration levels, their cause and<br />

remedial measure is a point of study.<br />

Development of suitable inspection tools such as Mobile Bridge Inspection Unit and test facilities such as for testing<br />

of expansion joints for bridges is of interest to professionals.<br />

A total of 9 projects have been reported out of which four are completed and five are on-going.<br />

UP Public Works Department, Lucknow (S)<br />

Scope and Objective<br />

The objective of this project is distress diagnostics of a<br />

PSC girder bridge and prescription of the rehabilitation<br />

scheme.<br />

Methodology<br />

This 2- lane bridge of 7.5m wide carriageway was built<br />

in 1973-74 and opened to the traffic around that time.<br />

The total length of this bridge is about 120 m arranged<br />

in a four span configuration of 29.0 m, 28.25 m, 28.25<br />

m and 29 m length (approx) resting on three piers<br />

and two abutments, through steel roller-rocker type<br />

bearings and separated by expansion joints. The deck<br />

comprises the slab supported by two PSC girders and<br />

RC cross- girders.<br />

The investigations comprised of identification of causes<br />

of distresses in the girders, assessment of quality of<br />

in-situ concrete in different components of the bridge<br />

through NDT, and load testing of one span of the bridge<br />

to assess the existing load carrying capacity of bridge.<br />

Interim Conclusions/Conclusions/Supporting Data<br />

Based on the investigations it is observed that the<br />

bridge is deficient in load carrying capacity and suitable<br />

scheme for rehabilitation and strengthening of the<br />

bridge are proposed.<br />

Significance/ Utilization Potential<br />

The findings of the study is useful for strengthening of<br />

the bridge<br />

Scope and Objective<br />

To study the noise and vibrations due to movement<br />

of heavy vehicular traffic on the Munirka Flyover, its<br />

impact on the buildings in its vicinity and suggesting<br />

remedial measures for reduction of noise and vibration<br />

levels.<br />

Methodology<br />

The following methodology was adopted:<br />

•<br />

•<br />

•<br />

•<br />

•<br />

Field measurements of parameters such as noise<br />

levels, acceleration and vibration velocity in X, Y &<br />

Z directions at various locations of the flyover and<br />

nearby residential buildings<br />

Measurement of displacement of the flyover<br />

superstructure during the movement of vehicles<br />

Analysis and comparison of field data with respect<br />

to noise and vibration with permissible limits<br />

Identify the cause for noise and vibration<br />

Suggestion of remedial measures to mitigate the<br />

noise and vibration problem of residents of nearby<br />

areas.<br />

Interim Conclusions/Conclusions/Supporting Data<br />

The measured noise levels at many residential buildings<br />

on both sides of the Munirka flyover are found to be high<br />

in night time compared to the CPCB recommended<br />

value of 45 dB by CPCB as the existing noise barriers<br />

was not fully effective in eliminating the airborne noise/<br />

vibrations therefore, suggestions have been given to<br />

modify these noise barriers.<br />

Based on the instrumentation and monitoring of the<br />

flyover and the surrounding buildings it has been<br />

observed that the frequencies of vibration of the flyover<br />

were quite close to the surrounding buildings which may<br />

cause enhancement of the vibratory response of the<br />

buildings particularly in night. However, the buildings<br />

were found to be safe due to traffic induced vibrations<br />

since these are RCC framed buildings.


The measured displacements of bridge superstructure<br />

Studies on damage assessment using<br />

Experimental Modal Analysis<br />

Experimental modal analysis has been carried out<br />

on the reinforced concrete slab strip to study the<br />

effect of damage on vibration characteristics towards<br />

identification of damage. Damage has been induced<br />

on the beam by applying static load in increments<br />

ROAD RESEARCH IN INDIA 2011-12 45<br />

and observed the damage behaviour at pre-yielding,<br />

yielding, post-yielding and ultimate stages. The<br />

reinforcement of the slab was instrumented with strain<br />

gages to get strain response during the static and<br />

dynamic loading. Vibration testing has been carried<br />

out on the slab by exciting with electro dynamic shaker<br />

and instrumented impact hammer. Vibration responses<br />

have been measured using the set of accelerometers<br />

fixed at bottom of the slab. Vibration testing has been<br />

carried out at undamaged as well as after each level of<br />

damage introduced by static loading. Because of limited<br />

number of sensors, roving acceleration testing was<br />

performed using five roving accelerometers with two<br />

reference accelerometers. The roving accelerometer<br />

setup as well as the excitation being applied using<br />

APS400 shaker and impact hammer is shown in Fig.1.<br />

First three bending modes were extracted from the<br />

synchronised roving accelerometer test data using<br />

enhanced frequency domain decomposition technique<br />

after restraining the support vertical displacements.<br />

Based on the signal analysis of the vibration data, two<br />

linear parameters; viz., frequency and damping which<br />

can be used as damage indicators were analysed. The<br />

linear damage indicators which can be immediately<br />

identified are the changes in frequencies and mode<br />

shapes. The frequency changes at different levels<br />

of damages were plotted and from which it can be<br />

observed that reinforced concrete immediately starts<br />

to crack in a continuous process and thus reduces<br />

stiffness and eigen frequencies.<br />

II. Studies on effect of corrosion on static and<br />

dynamic behaviour of rC structures<br />

Experimental investigations were carried out on<br />

post-tensioned prestressed concrete beams of size<br />

150x300x3000mm with M45 grade concrete, to study<br />

the effect of tendon corrosion on the static and dynamic<br />

behaviour of the beam. The prestressing wires used in<br />

the beam have been subjected to predetermined level<br />

of accelerated corrosion. At different corrosion levels,<br />

static and vibration testing of the beams were carried<br />

out to obtain the static and vibration responses which<br />

further were analysed for identifying the corrosion<br />

damage in the beam.<br />

Initial corrosion test was conducted on two prestress<br />

wires to study the change in stress and strain with


46<br />

corrosion. Accelerated corrosion was induced on<br />

two 7mm dia HTS wires, length 600mm to induce<br />

uniform corrosion in the wire as it occurred natural<br />

way and to find reduction in the capacity and diameter<br />

of wire. Measured average weight of metal loss and<br />

final diameter of the corroded bar were 34 grams and<br />

5.6mm, respectively. Tension test on the corroded and<br />

uncorroded bars were conducted. From the tests, it<br />

was found that the ultimate stress of corroded bar was<br />

reduced by 22% compared to that of uncorroded bar.<br />

Ultimate strain of corroded bar was 0.44 times that of<br />

the uncorroded bar.<br />

Static and vibration tests have been conducted on<br />

the beam with and without prestress before the start<br />

of the accelerated corrosion test. Fig.2(a) shows the<br />

experimental test setup of the beam and Fig.2(b)<br />

shows the setup for accelerated corrosion testing. Static<br />

loading was applied up to first cracking stage and the<br />

load deflection curve up to first cracking stage and the<br />

tensile and compressive strains at bottom and top on<br />

concrete surface at mid-span of beam were plotted.<br />

III.<br />

Studies on fatigue remaining life assessment<br />

of bridge structures<br />

Studies were carried out on fatigue remaining life<br />

assessment of a typical plate girder steel bridge.<br />

Different fatigue damage models and Linear Elastic<br />

Fracture Mechanics (LEFM) have been considered for<br />

evaluating the remaining service life of a typical steel<br />

railway bridge. The models were used to evaluate the<br />

reimaging service life of the bridge using the data of<br />

strain-time histories obtained from the experimental<br />

investigations. The strain response (Fig.3) from the<br />

weld due to passage of the train has been considered.<br />

By considering the uncertainties in load model and<br />

model factor obtained from stress analysis, the reliability<br />

index versus fatigue remaining service life curves were<br />

developed. The fatigue remaining life of the girder by<br />

incorporating corrosion effect was also evaluated by<br />

GENERAl REPORT ON<br />

assuming uniform surface corrosion rate of 0.03mm/<br />

year. The reliability index curve was modified to account<br />

for corrosion effect.<br />

recommendations for further Work<br />

In the present project, relative damage assessment<br />

of structural components was carried out by exciting<br />

them with impact hammer / electrodynamic shaker.<br />

Single shaker with multiple outputs (SIMO) is found<br />

to give good estimate of modal information. For large<br />

scale structures, procedure involving multiple shakers<br />

with multiple outputs (MIMO) needs to be developed.<br />

Also, as the sensor technology is improving, a potential<br />

application of dynamic testing is linking this with wireless<br />

communications and GPS (global positioning systems)<br />

which will certainly make dynamic system identification<br />

a possibility for remote health monitoring.<br />

Reinforcement<br />

by Externally Embedded<br />

Date of Start: March 2009<br />

Date of Completion: June 2011<br />

CSIR-Central Road <strong>Research</strong> Institute, New<br />

Delhi (R, I)<br />

Scope and objective<br />

The objective of the project is to study the performance of<br />

rectangular reinforced concrete (RC) beam specimens<br />

strengthened by externally embedded reinforcement.<br />

Also, to study the enhancement of shear capacity in<br />

comparison to standard specimens for field applications<br />

for strengthening of bridge component.<br />

present status and progress<br />

Rectangular reinforced concrete beams of size<br />

150x250x2000 mm were fabricated in the laboratory


48<br />

with different deficiency in shear capacity. The specimen<br />

were strengthened by using near surface mounted<br />

reinforcement such as steel strips and Carbon Fiber<br />

Reinforced plastic (FRP) strips at an inclination of<br />

about 45 degree to the longitudinal axis of the beam.<br />

The strips were embedded after carving out grooves on<br />

the both vertical face of the beam in shear region. The<br />

minimum groove width of the groove was kept 3 times<br />

the thickness of the strip and depth about 1.5 times the<br />

depth of the strip. The specimens were instrumented for<br />

strain measurements and deflection during the testing.<br />

Specimens were tested under three-point loading which<br />

was applied through hydraulic jack<br />

Fig. 1 Failure modes of some of the tested specimens<br />

Further findings/Conclusions/Supporting Data<br />

Strengthening of structures with Near-Surface Mounted<br />

(NSM) –FRP as well as steel reinforcement is an<br />

economical and feasible technique. From the laboratory<br />

study it has been observed that NSM technique<br />

reduced the risk of debonding in comparison to<br />

externally bonded technique due to better bond. Further<br />

it is also observed that the rehabilitation of concrete<br />

structure using externally embedded reinforcement in<br />

the concrete cover (NSM) technique is quite effective<br />

for shear deficient elements. The carbon FRP strips<br />

did not rupture as the recorded strain was less than<br />

the effective strain. The ratio test to theory shear<br />

test thry contribution by NSM strips (V / Vf ) of the NSM<br />

fd<br />

strips obtained was more than one (safety condition) in<br />

all the specimens. The same is the case on considering<br />

the ratio of V u<br />

test and Vu<br />

thry . The NSM shear strengthened<br />

specimens have exhibited a higher stiffness, mainly<br />

after the initiation of the shear crack. The contribution<br />

GENERAl REPORT ON<br />

of FRP for shear strengthening is comparable with the<br />

specimen having internal shear stirrups.<br />

limitations of Conclusions or Interim Conclusions<br />

The study does not cover the behaviour under the<br />

dynamic loading.<br />

recommendations for Further Work<br />

More studies are needed to consider the affect of the<br />

progress:<br />

The objective of this project is to evaluate the corrosion<br />

susceptibility of coated reinforcements embedded in<br />

ordinary concrete against high performance concrete<br />

made with un-coated reinforcement.<br />

The scope of the project consists of study of corrosion<br />

susceptibility of fusion bonded epoxy coated<br />

reinforcement (FBECR), hot-dip galvanized (HDG)<br />

bars, and thermo-mechanically treated (TMT) bars,<br />

embedded in the ordinary concrete with a 28 day<br />

compressive strength of 35 and 40 MPa, and the<br />

high performance concrete (HPC), of similar strength<br />

ranges, embedded with un-coated reinforcement bar.<br />

An Rapid Chloride Permeability Test (RCPT) value of<br />

800 coulombs and 1200 coulombs has been chosen as<br />

requirement for HPC. For the HPC mixes the following<br />

combinations (i) GGBFS + Silica fume, (ii) Fly ash +<br />

Silica fume, (iii) GGBFS + Fly ash + Silica fume have<br />

been selected.<br />

During the reporting period the material properties of<br />

epoxy coated rebars, hot dip galvanized bars and TMT<br />

bars were evaluated prior to their use for casting of<br />

various test specimens.<br />

150 mm, and three nos. of slab moulds of size 100 x<br />

500 x 500 mm were got fabricated in CRRI. Although,<br />

the conventional (carbon) steel was to be used as uncoated<br />

(reference) steel bar in the study, it was noticed<br />

that the same was not available in the market and<br />

only the TMT bars are available. Accordingly, with the<br />

permission from the sponsor, the TMT bars were used<br />

as un-coated reference bars. Accordingly, the TMT<br />

steel bars were purchased, and rebar cages for beams<br />

were fabricated<br />

One set comprising of rebars of different diameters and<br />

lengths (required for rebar cages and other tests) were<br />

sent to a zinc-coating applicator located in Delhi and<br />

got the galvanizing done on the rebars. Fusion bonded<br />

epoxy coated rebars (FBECR), of desired lengths and<br />

diameters in sufficient quantity, were procured from its<br />

manufacturer. Rebar cages of both the above special<br />

types of reinforcement were got fabricated.<br />

Concrete casting was carried out using ready mixed<br />

(conventional) concrete of grades M 35 and M 40.<br />

1. Assessment of Drivers’ Driving Characteristics<br />

Using Advance Driving Simulator.<br />

Date of Start: Sept 2011<br />

Date of Completion: August 2012<br />

CSIR- Central Road <strong>Research</strong> Institute, New<br />

Delhi (R)<br />

Scope and Objectives<br />

The aim of this study was to explore the relationship<br />

between driver distraction level and different distraction<br />

stimuli with the frequency and types of risk taking<br />

practices while driving.<br />

Methodology<br />

Sample: 55 male, female learner and professional<br />

drivers participated in this study.<br />

Process: In the present study participants were<br />

conducted driving tests in both highway and city area<br />

under simulated high traffic conditions. They were<br />

tested by under various distractions levels e.g. using<br />

cell phone dialling and SMS while driving, chatting<br />

to the peer group, listening music, changing CD and<br />

doing hand movements while driving and the number<br />

of correct responses and numbers of errors committed<br />

were measured . The data collected was analysed<br />

on the basis of driver’s age, gender, profession,<br />

qualification and driving experience.<br />

Significance/ Utilization Potential<br />

The study highlights various distraction levels of the<br />

drivers of both genders and pattern of risk associated<br />

with using mobile phones while driving and also<br />

analysis of crash patterns due to the lack of his/her<br />

concentration level while driving.<br />

Conclusions/ Findings<br />

•<br />

•<br />

•<br />

•<br />

Overall percentage of all the sample committed<br />

less errors without distraction<br />

Female drivers performed more safe with and<br />

without distraction<br />

Professional drivers and more experienced drivers<br />

were taking more risks e.g. high speeding, signal<br />

violations as compared to learner and newly<br />

experienced drivers<br />

Male drivers committed more errors while calling<br />

on cell phone while females did more errors while<br />

typing text messages<br />

• Highly professional<br />

drivers were showing false self<br />

perception and over confidence<br />

2. Driving Effect on Visual Fatigue and Blood<br />

Pressure of the Drivers<br />

Date of Start: August 2011<br />

Date of Completion: September 2012<br />

CSIR- Central Road <strong>Research</strong> Institute, New<br />

Delhi (R)<br />

Objective and Scope of the Study<br />

The main purpose behind this study was to test the<br />

physiological status of the drivers before and after<br />

exposure in real traffic environment.<br />

Methodology<br />

Data collected from 15 drivers participated in pilot study<br />

whereas 56 drivers participated in the main study. All<br />

the drivers were aged between 26 to 36 year age group.<br />

The drivers were administered Visual fatigue test after<br />

Blood Pressure monitoring and before starting the on<br />

field driving test and again the same test were repeated<br />

with the blood pressure monitoring after returning from<br />

the driving test (without resting). The data collected<br />

was analysed on the basis of driver’s age, gender,<br />

profession, qualification and driving experience.<br />

Findings<br />

•<br />

•<br />

•<br />

•<br />

Drivers were showing very high BP and showing<br />

hypertension situation before going to field test.<br />

14% drivers had pulse rate before above 92 pulse<br />

rate. Only 36% drivers were showing up to 72 BPM<br />

pulse rate which highlight that the drivers were very<br />

stressful and hyper tensed during the pretesting<br />

conditions<br />

During post trip session only 26% drivers were<br />

having above150 mmhg systolic blood pressure<br />

while other were showing lesser B.P. ; while 68%<br />

driver were having 80 mmhg or below diastolic<br />

blood pressure level which is showing a good sign<br />

of mental relaxation<br />

Data analysis revealed that VF values i.e Visual<br />

Fatigue Values decreased after field test. 4%<br />

drivers and 5% drivers have shown 50-55 Hz and<br />

45-50 Hz VF values i.e. both eyes visual fatigue<br />

values before field test period which is very high<br />

and showing high Visual Fatigue but after field test<br />

i.e. Post test period drivers were somehow relaxed<br />

and shown lesser visual fatigue values on higher


side i.e. 0% at 50-55 Hz for both eyes and 2% for<br />

45-50 Hz.<br />

Significance/Utilization Potential<br />

The findings of this study are significant enough to<br />

address the present working conditions and hours of<br />

working schedule of the professional drivers in India.<br />

As per Motor Vehicle Act 1988, 8 hour is the norm to<br />

be followed in terms of maximum working hours in a<br />

day for the commercial drivers, it is invariably seen<br />

that <strong>Indian</strong> commercial work more than 12 hours which<br />

is not only hazardous for the driver’s health but also<br />

increases the chances of road crashes due to physical<br />

and mental fatigue. It is essential to follow a realistic<br />

work schedules that takes care of the realities of traffic<br />

congestion, needs for breaks and rest periods. This<br />

should be kept in mind to ensure that drivers do not<br />

become the principal victims in absorbing the failures<br />

of the transport system and the workers that bear the<br />

brunt of cost cutting. Drivers should be given longer<br />

breaks and wherever possible breaks that facilitate<br />

adequate rest.<br />

3. Analysis of Driver Behaviour and Crash<br />

Characteristics during Adverse Weather<br />

Conditions<br />

Date of Start: May 2012<br />

Date of Completion: May 2014<br />

CSIR- Central Road <strong>Research</strong> Institute, New<br />

Delhi (R)<br />

Scope and Objectives<br />

•<br />

•<br />

•<br />

To capture drivers visual and measurable fatigue<br />

during fog driving under simulated environment<br />

and realistic setting.<br />

To investigate and analyze drivers’ choice of<br />

headway and speed in fog under simulated<br />

environment and realistic setting.<br />

To investigate if the choice of speed and headway<br />

are affected by the vehicle they drive or follow (under<br />

simulated environment and realistic setting).<br />

Methodology<br />

This study has been conducted in two parts:<br />

a) the observation and analysis of driver’s r.t. and<br />

other behaviour in laboratory setting under foggy<br />

ROAD RESEARCH IN INDIA 2011-12 55<br />

and rainy conditions: During the data collection,<br />

primary focused was on individual reactions to<br />

driving conditions. There was increasing focus on the<br />

behaviour of individual driver’s age, and other factors<br />

like fatigue etc. which impact driver behaviour. In this<br />

part psychophysical tests e.g. visual fatigue test, visual<br />

acuity test along with the driving simulation tests were<br />

conducted to analyze the driver behaviour i.e. crash<br />

characteristics, risk taking practices, reaction time<br />

under rainy and foggy conditions.<br />

b) the observation and analysis of driver’s driving<br />

characteristics in field setting: Field observations<br />

of driver’s speed variations have been measured to<br />

understand how individual drivers respond to certain<br />

stimuli, and how specific categories of drivers respond. In<br />

this part this driver’s characteristic have been measured<br />

with the help of the GPS based instrument Velocity-<br />

Box (V-Box) fitted with the three cameras to measure<br />

driver’s reaction time, behavioural movements and<br />

road assests during the acquisition. First camera was<br />

allowed to monitor of eye movements and other facial<br />

movements. Its field-of-view accommodated drivers of<br />

varying heights and seating positions. Second camera<br />

was providing a wide view of the forward roadway<br />

without substantial distortion. This Camera was located<br />

in the center rear-view mirror and did not obscure any<br />

part of the driver’s view of the roadway or impair his/<br />

her use of the mirror. This camera served to collect<br />

relevant data from the forward scene (e.g. traffic density,<br />

signs and markers, and headway). Third camera was<br />

providing a view of driver’s foot movements which was<br />

stored automatically for measuring the reaction time of<br />

the driver during different traffic conditions.<br />

The study second part will be conducted during extreme<br />

winter foggy conditions (December and January) and<br />

an evaluation of relationships of all drivers’ personality<br />

characteristics. Factor analysis will be conducted<br />

to analyse several at-risk driving behaviours and<br />

a cluster of correlated driving behaviours will be<br />

identified which will share a common characteristic as<br />

aggressive/impatient driving. This correlated cluster<br />

of driving behaviour will provide objective support<br />

for the assumptions of response generalization and<br />

characteristics and driving style will be analysed to find<br />

out the driver’s problem behaviour theory. Results<br />

will be discussed with regard to implications for safe<br />

driving interventions and a suggesting remedial for<br />

problem behaviour syndrome.<br />

Significance/ Utilization Potential<br />

Human factors research is an important element in the<br />

analysis and design of these systems. Significant part<br />

of the project would be obtaining driver behavioural<br />

data at reverse weather conditions. The study will also<br />

focus on crash modelling in fog, which will provide


56<br />

insight about possible damages and injuries in fog<br />

related crashes. The final project report will address<br />

the answers of the four research questions identified<br />

in this study. Specifically there will be findings related<br />

to drivers’ state, and pattern of crashes during rain and<br />

foggy conditions. Based on these findings the research<br />

team will also recommend ways by which frequency<br />

and severity of incidents can be reduced by providing<br />

drivers with enough information about the roadway<br />

and traffic conditions as well as through better traffic<br />

management during adverse weather conditions.<br />

Field observations of decreased speeds and greater<br />

headways can be better understood by observing how<br />

individual drivers respond to certain stimuli, and how<br />

specific categories of drivers respond. This information<br />

is particularly helpful in light of the growing deployment<br />

of ITS technologies. Motorist warning systems that<br />

notify drivers through roadside Dynamic Message<br />

Signs (DMS) about weather-related conditions such<br />

as fog, flooding, or slippery pavement are deployed by<br />

some transportation agencies. The benefits of these<br />

systems can be maximized if agencies can optimize<br />

the location and provide the most effective warning on<br />

the sign itself.<br />

based on various geometric, social and economic<br />

indicators and a priority list of roads which are to be<br />

improved was prepared.<br />

limitations of Conclusions/ recommendations for<br />

further work<br />

The list includes a total of 18 roads (37.32 km), including<br />

to PWD roads. Of this, immediate attention should be


58<br />

given to the PWD roads as they have been found to be<br />

damaged all along its length. Water logging has been<br />

the main reason, causing damage to roads. The two<br />

district Panchayath roads also need to be improved at<br />

the earliest as they will serve a large population and<br />

other societal needs and have adequate Right of Way<br />

for widening. Other roads listed may be improved in<br />

a phase wise manner, taking into consideration of its<br />

weightage values. The roads need to be given priority<br />

those road width having six metres or above. The roads<br />

have a width of eight metres; they could be improved<br />

under some of the centrally sponsored schemes like<br />

8. Route Network Planning of Inland Water<br />

Transport for Kerala – Phase 1 – Central<br />

Kerala<br />

Date of Start: March 2011<br />

Date of Completion: March 2012<br />

National Transportation Planning and <strong>Research</strong><br />

Centre - (R)<br />

Scope and Objectives<br />

To assess the utilization of the waterway network for<br />

transport and to identify new routes for boat trips so as<br />

to establish an efficient and integrated transportation<br />

system for Kerala.<br />

Methodology<br />

The methodology involved a detailed survey of the<br />

waterways in the study area in order to take stock of<br />

the existing condition. The details regarding the boat<br />

operation, no. of trips, no. of passengers, location of<br />

jetties and connectivity to road etc. will be found out<br />

from primary surveys as well as sources like Tourism<br />

Department, Inland Waterways Authority of India,


District Tourism Promotion Council (DTPC), local bodies<br />

and private operators. O-D Survey and questionnaire<br />

survey will be conducted for finding out the travel<br />

demand. An integrated transportation plan will be<br />

prepared for the area including suggestions to develop<br />

the waterways so as to make them fit for navigation,<br />

by provision of navigational aids, jetties, landings and<br />

other infrastructure facilities. Proposals for integration<br />

of the waterways with other modes like road and rail<br />

etc. will be worked out so as to make the transportation<br />

system more efficient. Tourism potential of the area also<br />

will be studied and sustainable improvement proposals<br />

will be prepared.<br />

Significance/Utilisation Potential<br />

The outcome of the study will be an integrated transport<br />

network plan for Central Kerala, which will help the<br />

Govt. as well as private operators in the unorganized<br />

sector to efficiently plan their services. Improved water<br />

transport network will enhance the connectivity as well<br />

as economy of the region as a whole and will also result<br />

in increased tourism revenue.<br />

limitations of Conclusions/ recommendations for<br />

further work<br />

The use of waterways is reduced due to the<br />

construction of new bridges and roads. Waterways are<br />

to be developed for tourism purposes. Central Kerala<br />

including Ernakulam, Kottayam, Alappuzha and Kollam<br />

Districts has a dense network of feeder canals, well<br />

connected with NW-3. Even today, some of the habitats<br />

of Kuttanad region are not connected by all weather<br />

roads. There are other locations which are connected<br />

by road, but closer to canals. Congestion of roads due<br />

to increase in population and industries are another<br />

major concern. Improving navigation across the canal<br />

system will therefore change the very socio- economic<br />

scenario of the region. A comprehensive planning of the<br />

water transport system will help in achieving an efficient<br />

and well integrated transport system for the region.<br />

The cargo potential of the waterway is to be studied and<br />

a strategy for suitable vessel design is to be developed.<br />

Cargo availability is another important aspect to be<br />

studied in detail.<br />

11. Integration of Public Transport - A Case Study<br />

of Thiruvananthapuram City<br />

Date of start : April 2011<br />

Date of completion : March 2012<br />

National Transportation Planning and <strong>Research</strong><br />

Centre (NATPAC) - R<br />

Scope and objectives<br />

The public transport services provided by State<br />

transport undertakings and private operators are<br />

seldom coordinated, causing hardships to travellers<br />

and regular commuters. Although it is possible to<br />

coordinate the transfer of passengers from one mode<br />

of public transport to the other, a holistic attempt has<br />

not been made to integrate public transport services<br />

through optimum utilization of available infrastructure<br />

and services.<br />

The objective of the study is to develop a methodology<br />

for optimizing the public transport services by providing<br />

effective coordination for transfer of passengers arriving<br />

by trains, to reach their destination in and around the<br />

City of Trivandrum.<br />

Towards this the following tasks have been performed:<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

Study the present travel pattern of commuters at<br />

terminals<br />

Identification of data and survey to be conducted<br />

for the study<br />

Arrival and departure pattern of passengers by train<br />

at Trivandrum Central Railway Station between<br />

06.00 hrs – 22.00 hrs<br />

Collection of data on passengers boarding the<br />

existing bus services from the Central Railway<br />

Station to various destinations in the city<br />

Formulation of Objective Function and constraint<br />

equations of linear programming approach for<br />

optimization focusing on minimizing passenger<br />

waiting time, and minimizing operator costs of the<br />

public transport providing the feeder services<br />

Working out an optimal bus frequency schedules<br />

for the feeder services<br />

Methodology<br />

Optimization of passenger waiting time and operator<br />

cost are carried out by linear programming approach.<br />

The objective function and the constrain equation are<br />

formulated. The optimum frequency of buses along


each sub route was computed using a non-linear<br />

optimization model implemented using Solver in<br />

Microsoft Excel. Additionally a sensitivity analysis was<br />

performed for each route separately considering the<br />

effect of bus- frequencies on waiting time, the cost of<br />

waiting time and the bus operating cost.<br />

Rail passenger survey was performed on 1% of the<br />

total passengers arriving at Thiruvananthapuram<br />

Central Railway station from 6am to 10pm. Details<br />

on the preferred mode of travel, and the destinations<br />

were obtained in addition to information on the income<br />

and occupation, economic class, cost to travel to<br />

their destination and the average waiting time. The<br />

data obtained from the survey was used as inputs for<br />

objective function in order to get optimized frequencies<br />

for different routes.<br />

Conclusions<br />

From the traffic survey conducted at Trivandrum Central<br />

Railway Station, the general trend of arrival passengers<br />

during different hours of the day was found. It was<br />

found that the peak hours of travel were 6-8 hrs, 9-12<br />

hrs, and 19-20 hrs, which contributed to 43% of the<br />

total passenger arrivals.<br />

The optimum frequency of buses was derived using<br />

the model for different routes and during different hours<br />

of day. It was observed that travel demand and the<br />

optimum frequency to meet the demand were different<br />

during different hours. Accordingly, the frequencies<br />

should be changed based on the demand rather than<br />

following a fixed schedule throughout the day. It was<br />

also found that the user cost and operator cost involved<br />

could be minimized by changing the frequency of<br />

buses operating along that sub-route. The analyses<br />

conducted proved that the bus-trips could be curtailed<br />

or diverted when the number of passengers along any<br />

route is below the specified limits. Optimization was<br />

done for all the three sub-routes of each route and the<br />

savings obtained when frequency of buses operating<br />

along the sub-routes is varied and the observations are<br />

as follows<br />

The observations on the optimization carried for Route<br />

1<br />

•<br />

The average load factor at peak, mid-peak, and<br />

off-peak hours were found to be 0.857, 0.70, and<br />

0.650 respectively, which were found to be within<br />

the operating load-factor constraints.<br />

• The bus-trips operating at off-peak hours along the<br />

sub-routes A, B, and C, was between 40 and 51%<br />

when compared to buses operating during the peak<br />

hours. This proves that the frequency of buses<br />

operating along the Route 1 could be curtailed by<br />

50% during the off peak hours. This could save a<br />

ROAD RESEARCH IN INDIA 2011-12 61<br />

lot of resources particularly from operator side.<br />

• The bus-trips operating at mid-peak hours along<br />

the sub-routes were between 46% and 90% when<br />

compared to buses operating during the peak<br />

hours.<br />

The observations on the optimization carried for Route<br />

2 are as follows:<br />

•<br />

The average load factor at peak, mid-peak, and<br />

off-peak hours were found to be between 0.50 and<br />

0.70 which were found to be within the operating<br />

load-factor constraints.<br />

• The bus-trips operating at off-peak hours along the<br />

sub-routes A, and B, were about 63%, and 68 %<br />

respectively when compared to buses operating<br />

during the peak hours.<br />

• Similarly, it be seen that bus-trips operating at midpeak<br />

hours along the sub-routes A, and B, were<br />

about 86%, and 77% respectively when compared<br />

to buses operating during the peak hours.<br />

The observations on the optimization carried for Route<br />

3 are as follows:<br />

•<br />

The average load factor at peak, mid-peak, and<br />

off-peak hours were found to be between 0.54 and<br />

0.650 which were found to be within the operating<br />

load-factor constraints.<br />

• The bus-trips operating at off-peak hours along the<br />

sub-routes A, and B, were about 79% and 85%<br />

respectively when compared to buses operating<br />

during the peak hours.<br />

• The bus-trips operating at mid-peak hours along<br />

the sub-routes A, and B, were about 79% and 107%<br />

respectively when compared to buses operating<br />

during the peak hours.<br />

Significance of the study<br />

A methodology was formulated to find the optimum<br />

frequency of buses to meet the travel demand<br />

considering various factors like waiting time, number<br />

of passengers and operator cost. An attempt has been<br />

made to reach at the optimum frequency of buses desired<br />

in each route, which satisfies both the commuters and<br />

operators. Optimized frequencies for different routes<br />

during different time period was generated using the<br />

model. It was observed that for economic operation<br />

of services the number of buses should be changed<br />

as per the demand. The study proves that number of<br />

buses required during the mid peak and off peak hours<br />

is less than those for peak hours. Hence it is suggested<br />

to alter the frequency of buses during different category<br />

of time as per demand.

12. Predictive Accuracy of Urban Transport<br />

Studies –A Case Study of Trivandrum and<br />

Cochin in Kerala<br />

Date of start : Aprl 2011<br />

Date of completion : March 2012<br />

National Transportation Planning and <strong>Research</strong><br />

Centre (NATPAC) - R<br />

Scope and Objectives<br />

The scope of study is confined to selected cities in<br />

Kerala State. A case study of Trivandrum and Kochi<br />

Urban Area were selected to analyze the variations<br />

in the forecasts made. The objectives of the study are<br />

given below:<br />

i.<br />

ii.<br />

iii.<br />

iv.<br />

To undertake an analysis of forecasting of socio-<br />

economic variables, travel behaviour and traffic<br />

flow pattern that has influence on demand<br />

forecasting;<br />

To evaluate the accuracy of forecast variables<br />

by comparing the study forecasts with the actual/<br />

observed data in the selected city;<br />

To critically examine the assumptions made<br />

in forecasts and the cause-effect in predictive<br />

accuracy of these variables;<br />

To prepare general guidelines for realistic<br />

assumption and forecasting of input variables in<br />

such studies.<br />

Methodology<br />

Different organizations have undertaken comprehensive<br />

Traffic and Transportation studies for a number of towns<br />

in Kerala during the last 30 years. Over 35 towns have<br />

been covered under various urban transport studies in<br />

Kerala. Available data from these studies have been<br />

utilized to assess the accuracy of various parameters by<br />

comparing the study forecasts with the actual changes<br />

that have taken place. An evaluation of variations in<br />

planning variable like population growth, employment,<br />

land use, vehicle ownership, traffic volume etc was<br />

performed. The assumptions made in the study were<br />

GENERAl REPORT ON<br />

also critically examined. Based on the evaluation of<br />

predictive accuracy of selected parameters, a general<br />

guideline for realistic assumptions and forecasting of<br />

variables has been recommended.<br />

Major findings and conclusions<br />

Considerable attention has been given, over the last<br />

decade or so, to improve the specification of models<br />

and the estimation of the planning variables, but little<br />

attention has been given to the effect of errors on the<br />

accuracy of the forecast. Data from 19 urban transport<br />

studies of Trivandrum and Kochi cities, undertaken<br />

between 1981 and 2011, were used to evaluate their<br />

predictive accuracy. The comparison of demographic<br />

and socio-economic variables forecast showed a trend<br />

of overestimation while the traffic parameters indicated<br />

a lack of incorporation of fundamental shifts in economic<br />

growth and societal changes.<br />

On an average, demographic variables (population and<br />

employment) of both cities were overestimated by 24<br />

percent for a forecasting period of 10 years. Almost<br />

all forecasts for land use types were overestimated<br />

by an average of <strong>39</strong> per cent in case of Trivandrum<br />

city, whereas for Kochi city, the forecasts were<br />

underestimated by an average of 17 percent. Traffic<br />

parameters like vehicle population and traffic flow were<br />

heavily under estimated for both cities by 13 to 94<br />

percent.<br />

The changes in household income for the horizon year<br />

was not at all foreseen and accounted for in the modelling<br />

process. Thus an important variable like per-capita<br />

income was not forecasted for the horizon year and the<br />

base year value was incrementally taken which further<br />

led to irregularities in predicting the vehicle ownership<br />

levels and the total vehicle population. Therefore, there<br />

occurred a flaw in the traffic flow assignment on the<br />

road network.<br />

Further analysis of the data showed that an assumption<br />

of zero variation from base year situation had mixed<br />

response. Such an assumption would have produced<br />

smaller errors for socio-economic variables like<br />

population, employment in case of Trivandrum City and<br />

larger errors in case of Kochi City. Assumption of zero<br />

variation would have produced larger errors for traffic<br />

parameters.<br />

The traffic forecasts which were highly inaccurate<br />

combined with large standard deviations translate<br />

into large financial and economic risks. But such<br />

risks are typically ignored or downplayed by planners<br />

and decision-makers, to the detriment of social and<br />

economic welfare.

13. Transport Infrastructure Development Plan for<br />

Harippad Town in Alappuzha district, Kerala<br />

Date of start : July 2011<br />

Date of completion : December 2012<br />

National Transportation Planning and <strong>Research</strong><br />

Centre (NATPAC)- R<br />

Scope and Objectives<br />

The aim of the study is to prepare a Transport<br />

Infrastructure Development Plan for Harippad Town<br />

in Kerala. The broad objectives of the study are given<br />

below:<br />

(i)<br />

(ii)<br />

To assess the present level of service of road and<br />

other transportation systems and to identify the<br />

traffic bottlenecks, in the study area;<br />

To collect traffic volume data on major roads and to<br />

assess the extent of shortfall of the road system;<br />

(iii) To assess geometric deficiency of road sections<br />

and requirement of parking and pedestrian facilities<br />

in Harippad;<br />

(iv) To formulate suitable short-term and medium-term<br />

improvement schemes for Harippad town;<br />

(v) To prepare long term Transport Development Plan<br />

for the study region.<br />

Methodology<br />

Keeping the general objectives of the study, the<br />

following tasks were carried out:<br />

i) Review of development proposals;<br />

ii) Collection of data through primary surveys;<br />

iii) Analysis and interpretation of data;<br />

iv) Preparation of improvement proposals and future<br />

development plan.<br />

For forecasting of future travel demand for the study, a<br />

horizon year of 2030 was considered and accordingly<br />

future levels of traffic on the road system were<br />

estimated. Based on the field studies and analysis of<br />

data, shortcomings in the existing road system have<br />

been identified and appropriate improvement proposals<br />

prepared. Improvement proposals are suggested in<br />

ROAD RESEARCH IN INDIA 2011-12 63<br />

two stages namely: (i) Short-term improvements and<br />

(ii) long-term transport development. Short-term<br />

measures are those schemes that involve no land<br />

acquisition which could easily be implemented in the<br />

next six months to one year period. These are intended<br />

to optimise the use of available road space and other<br />

transport facilities at minimum cost with maximum<br />

benefits. These schemes can, effectively, cater to the<br />

needs of Harippad Region the next five to 10 years.<br />

The various short-term schemes suggested are: Traffic<br />

improvement plan for central areas, road signage<br />

plan, parking-lots, provision of pedestrian facilities,<br />

segregated bus bay at selected bus stops and roadway<br />

beautification scheme.<br />

long-term schemes are those that are essentially<br />

required to meet the anticipated traffic demand for the<br />

next 10-20 years period. The suggested proposals<br />

include: widening of existing roads to meet the<br />

required standards, construction of missing links,<br />

and improvement of road connectivity to Harippad<br />

Railway Station, development of off-street parking lots,<br />

integrated bus terminal and Transport Infrastructure<br />

Development Plan for the year 2030. A ring road for the<br />

town has been recommended as a part of long term<br />

road network plan.<br />

14. Traffic Forecasts for Personal Rapid Transit<br />

(PRT) System for Thiruvananthapuram City<br />

Date of start : March 2012<br />

Date of completion : August 2012<br />

I.<br />

II.<br />

National Transportation Planning and <strong>Research</strong><br />

Centre (NATPAC) –R<br />

Infrastructures Kerala Ltd. (INKEL)<br />

Scope and Objectives<br />

Personal Rapid Transit system is a modern, demand<br />

responsive transit which uses automated pod-cars<br />

with battery operations running on elevated guide-way.<br />

Each pod will carry up to 6 passengers and operate<br />

with an average speed up 40 km/hour. It is intended to<br />

provide last mile connectivity to travellers in cities. The<br />

objective of the study is to identify major travel corridors


64<br />

for operating PRT system in Thiruvananthapuram City,<br />

estimate expected ridership between different stations<br />

and forecast ridership for various horizon years.<br />

Methodology<br />

The methodology adopted for the study is split up into<br />

a set of tasks as given below;<br />

a)<br />

b)<br />

c)<br />

d)<br />

e)<br />

f)<br />

Collection of traffic data and other relevant<br />

information both from primary surveys and<br />

secondary sources for arriving at base year travel<br />

demand models;<br />

Generation of base year travel pattern in the form<br />

of O-D matrices;<br />

Development of transit networks and validation of<br />

trips through traffic assignment;<br />

Calibration of base year travel demand models;<br />

Forecasting of transit ridership on selected routes<br />

of PRT network for a concession period taking into<br />

account of various alternative scenarios and fare<br />

sensitivity;<br />

Conducting fare sensitivity and risk analysis with<br />

respect to projected ridership.<br />

Conclusions<br />

It has been estimated that more than 8 lakh person trips<br />

were performed in a day in the study region, of which,<br />

almost 80 per cent of the movement had either origin<br />

or destination outside Thiruvananthapuram city region.<br />

The expected ridership for PRT system in the base<br />

year (2012) works out to 1.42 lakh person trips. The<br />

potential users of PRT system would include 46% of<br />

existing two wheeler users, 27% of bus users, 17% from<br />

among the car users and the rest of demand come from<br />

intermediate public transport modes like auto rickshaw<br />

and taxi users. The ridership would increase to 1.80<br />

lakh trips if adequate parking facilities are provided at<br />

major transfer points and the time of operation of the<br />

system is enhanced to 20 hours a day.<br />

It is estimated that the ridership for PRT system would<br />

increase to 2.88 lakhs in the year 2020, and further<br />

increase to 8.45 lakh trips by 2045. The fare elasticity<br />

of travel demand is worked out as -0.81 implying that an<br />

increase of 10% fare level will result in 8.1% decrease<br />

in travel demand.<br />

Considering the anticipated passenger demand on<br />

different corridors of the proposed PRT network,<br />

a phased programme for implementation has<br />

been recommended for a distance of 12.5 Km in<br />

Thiruvananthapuram city.<br />

GENERAl REPORT ON<br />

Phase - 1: East Fort – Thampanoor - Palayam with a<br />

connection to Govt. Secretariat. (Distance 3.8 Km.)<br />

Phase - 2: Palayam –Museum -Vellayambalam -<br />

Kowdiar Square (Raj Bhavan) and also a connection to<br />

Vellayambalam via Vazhuthacaud. (Distance 5.0 Km.)<br />

Phase - 3: East Fort –Sreekandeswaram - Vanchiyoor<br />

– General Hospital – Kerala University and Palayam<br />

(Distance 3.5 Km.)<br />

The traffic demand estimated for the base year as<br />

well as for different horizon years justifies the guide<br />

way based pod-car operation in selected corridors of<br />

Thiruvananthapuram city. The proposed PRT System<br />

will serve as feeder transit service, providing last mile<br />

connectivity to Bus/Railway Stations, Govt. Secretariat<br />

and various activity centres in the city. With the<br />

introduction of PRT system, a substantial reduction of<br />

journeys by private vehicles and auto/ taxis would be<br />

possible, thereby resulting in significant reduction of<br />

traffic congestion in Thiruvananthapuram city.<br />

Scope and Objectives<br />

Objectives:<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

To identify and implement ITS tools in the area<br />

of urban speed management, applicable to<br />

Tiruchirappalli city traffic conditions.<br />

To explore the use of ANPR cameras for vehicle<br />

identification and speed detection of individual<br />

vehicles.<br />

To identify and propose the technology for providing<br />

appropriate speed warnings to those users violating<br />

speed limits and to study the influence of such<br />

warnings on the speed pattern.<br />

To explore the use of image processing technique<br />

in estimating speed of moving vehicles.<br />

To evolve guidelines and best practices for<br />

maintaining proper speed management.<br />

To develop human resources by training planners,<br />

traffic enforcement personnel and road users.<br />

Scope:<br />

The scope of the study is to implement an efficient<br />

traffic regulatory and management system to regulate<br />

speed and in turn reduce the number of accidents as a<br />

result of increased speed through an efficient ITS tool<br />

and ensure safe and efficient travel in the study area,<br />

Tiruchirappalli City.<br />

Methodology<br />

Stage I: Identifying the required tools and locations for<br />

installing the tools<br />

The tools identified for the urban traffic speed<br />

management study are ANPR cameras that would<br />

capture images (of number plates of vehicles), at<br />

suitable resolution and frame rate; and RADAR/lIDAR<br />

speed meter and identifying the locations for installing<br />

the tools, based on traffic characteristics, accident<br />

data etc. The data collected would be transferred to<br />

a computer setup at a suitable location via long cable<br />

wires or Wi-Fi systems.<br />

Stage II: Analysing Urban Traffic Speed<br />

Using video detection technology the speed of vehicles<br />

is estimated using the ANPR cameras. The speed and<br />

the number plate of the vehicle extracted is transferred<br />

to a database for further operation.<br />

Stage III: Dissemination/utilization of information<br />

It is then proposed to utilize the information obtained on<br />

speed profiles estimated using both the technologies<br />

for managing the traffic by providing suitable driver<br />

GENERAl REPORT ON<br />

feedback signs of the over speeding vehicles using<br />

VMS, Voice messages, Image display systems and<br />

studying the effect of speed warnings on the speed<br />

pattern.<br />

Stage IV: Implementation of the ITS technologies<br />

considered and assessing their suitability<br />

The chosen technologies have to be tried out on an<br />

experimental basis and in collaboration with City<br />

Corporation and Traffic Police of Tiruchirappalli city.<br />

The results of the implementation will be evaluated and<br />

compared with experiences in Delhi, Mumbai, etc.<br />

Conclusions<br />

•<br />

•<br />

•<br />

Cars contribute around 50% of excess speed on<br />

Bharathidasan road, while on rest of the road excess<br />

speed is mainly contributed by two wheelers.<br />

There has been a significant variation of speed<br />

along previous non-accident zones following the<br />

accident zones.<br />

Speed prediction models were developed for roads<br />

with and without median. linear and generalized<br />

linear models were used for developing models.<br />

3. To carry<br />

out necessary techno-economic evaluations<br />

for selecting the most feasible alignment for the<br />

above green field road.<br />

The scope of the study covers only the preliminary<br />

technical aspects of identifying all possible alignments,<br />

assessment of existing land uses, traffic demand,<br />

and evaluation of alternative alignments, preliminary<br />

(conceptual) alignment drawings and preliminary<br />

design and preparation of rough cost estimate.<br />

by conducting reconnaissance, inventory and GPS<br />

Surveys and verification with topo sheets;<br />

Preparation of preliminary (conceptual) drawings<br />

and designs;<br />

Preparation of rough cost estimate;<br />

Interim Conclusions/Conclusions<br />

Although Kochi is well connected to other regions<br />

with rail, road and air linkages, the quality of transport<br />

infrastructure and mobility standards are far from<br />

satisfactory. The vertical growth and land use expansion<br />

in and around Kochi are bound to generate and attract<br />

heavy commuter and goods traffic which the existing<br />

transport network system cannot handle. Government of<br />

Kerala and Government of India are evolving many new<br />

schemes to improve the existing transport infrastructure<br />

of Kochi and adjoining region substantially. The concept<br />

of Kochi Metro and constructing a new Greenfield road<br />

between Kundannur, Vytila and Nedumbassery has<br />

emerged as a result of this thinking.<br />

6. The estimate on cost of road construction is made<br />

for two lane or four lane road standards based<br />

on the unit rates available for each items of civil<br />

works.<br />

Significance of the study<br />

The Malabar region remains undeveloped as compared<br />

to other regions in the State. The Government of Kerala<br />

intends to provide the much needed connectivity to the<br />

Malabar region especially along the coastal belt. The<br />

coastal belt of Ponnani-Vengalam region in Malabar<br />

mostly depends on the existing Tippu Sultan road for<br />

connection to the hinterland. This road was constructed<br />

centuries ago and does not meet the required standards<br />

and also not well-maintained.<br />

limitations<br />

Based on the analysis of secondary data and reports<br />

of other agencies, detailed field reconnaissances were<br />

conducted by NATPAC on the proposed coastal highway<br />

alignment. The report contains the brief features of the<br />

selected alignment, its economical and social impacts,<br />

pavement design, updated cost estimates, economic<br />

analysis and other relevant engineering features. It is<br />

proved beyond doubt that the new coastal highway<br />

between Ponnani and Vengali in Malabar region will go<br />

a long way for the overall economic development of the<br />

State.<br />

Conclusions<br />

With reference to Road Safety Cell, NHAI, Dwarka,<br />

New Delhi and Project Director (PIU, Gandhidham)<br />

regarding the study in view of the frequent accidents<br />

on Palanpur- Bhildi section of NH-14 covering the three<br />

locations at Chadotar (Km. 353/000), Chandisar (Km.<br />

357/000) and Bhildi (Km. <strong>39</strong>7/000). The CRRI study<br />

team visited the site in the month of April – May 2012<br />

and identified methodology to conduct the traffic studies<br />

and the following are the observations from the study<br />

•<br />

•<br />

•<br />

•<br />

•<br />

The analysis of above traffic studies clearly<br />

indicating that as per the IRC norms the required<br />

traffic volume is not exisitng to propose any grade<br />

seperated facility. However the pedestraina studies,<br />

spot spott studies and accidents stuides reveal that<br />

accidents are occuring mainly due to mix of local<br />

traffic travelling about 15-20 kmph with high speed<br />

naitonal highway traffic travelling with average<br />

speeds above 65 Kmph.<br />

In addition to this, the highway traffic also mixing<br />

up with local <strong>No</strong>n-motorized and Pedestrain traffic.<br />

Further the accidents stuides on this streatch<br />

clearly indicates that these three locations has very<br />

high potential for the accidents.<br />

In view of all these, the Vehicualr Underpass ( VUP)<br />

at the two locations i.e. at Chatodar (Km. 353/000)<br />

and Chandisar (Km. 357/000) and Pedesstrain<br />

Underpass (PUP) at Bhildi in recommded.<br />

Further it is mentioned that desining of these<br />

intersections as staggered intersections are not<br />

recommeded considering the high speeds on<br />

the national highway which in turn creates more<br />

problems to the local as well as national highway<br />

traffic.<br />

Provision of the VUP and PUP at the respective<br />

lcoations will ehnace the safety of local traffic well<br />

GENERAl REPORT ON<br />

as national highway traffic. Since these locations<br />

are situiated very proximitly to the urban settlements<br />

Comprehensive Traffic and Transportation<br />

Studies of Goa.<br />

Date of Start: Sep 2010<br />

Date of Completion : Oct 2012<br />

CSIR- Central Road <strong>Research</strong> Institute, New<br />

Delhi<br />

Scope and Objectives<br />

The study would be conducted in two phases namely<br />

short term (Phase-I) and long term (Phase II).<br />

The scope of the study in Phase-I encompasses<br />

conducting field studies for the preparation of Traffic<br />

System Management Plans for all the five traffic circles.<br />

Study of major intersections on national highways<br />

corridors in addition to the other major roads. On the<br />

basis of set of traffic surveys proposed to be conducted<br />

on the identified road network of the city, short term<br />

traffic improvement plans would be recommended.<br />

Comprehensive road network plan such as multi-modal<br />

transport system considering transport requirements<br />

of existing and future travel demands is to prepare in<br />

Phase II. In the long term study under phase II, the<br />

household travel characteristics and establishment<br />

surveys will form the basis for recommending transport<br />

plan for the horizon years.<br />

Methodology<br />

The short term solutions will provide relief to the<br />

congestion and chaotic situations of traffic. To achieve<br />

perceivable relief certain minimum required structural<br />

changes and mandatory controls will have to be devised.<br />

These changes may be in the form of geometric design<br />

of intersections and provision of signals to control the<br />

movements at intersections by allocating the right of


way. Besides this, the parking characteristics would be<br />

analyzed and polices for parking regulations in terms<br />

of time rationing, physical restrictions, designing and<br />

control of off-street facilities will be undertaken. Safety<br />

measures at some accident prone zones along the<br />

National <strong>Highway</strong>s passing through the Goa cities to<br />

be recommended.<br />

The parking needs of the central business area will be<br />

assessed at more detailed level to work out regulatory<br />

steps which might include physical and fiscal measures.<br />

Pedestrian facilities will be recommended on the basis<br />

of scientific study of pedestrian counts along the roads<br />

and across the roads.<br />

long term solutions are aimed at developing the<br />

transport infrastructure and related system in a scientific<br />

manner by considering the planned growth of the city<br />

and estimating the future travel demand. This shall be<br />

accomplished by systematically conducting the primary<br />

surveys to assess the transport demand of passenger<br />

and goods as existing and evolve transport models<br />

to project this demands for the horizon years. On the<br />

basis of estimating demands the master plans of roads<br />

with appropriate hierarchical set-up will be prepared.<br />

Efforts will also be made to identify the phase wise<br />

development of this proposed master plan:<br />

Significance/ Utilization Potential<br />

The recommendations were made to implement the<br />

action plan on ground expecting to reduce traffic,<br />

parking problems and pedestrian problems. And Phase<br />

wise development of road network would immensely<br />

help to reduce the congestion as well as accidents on<br />

road network of Goa.<br />

Status: Completed<br />

Year of Last Report: 2012<br />

progress: Completed. This project is one of the CSIr-<br />

eMpoWer Scheme Project<br />

Further Findings/Conclusions<br />

The variation of Travel Time was investigated under<br />

the influence of various uncertainties from the Supply<br />

and Demand side of the Transportation system with the<br />

help of Micro simulation techniques<br />

Travel distributions Observed Vs Simulated<br />

•<br />

•<br />

•<br />

•<br />

Travel time obtained by simulation model is well<br />

distributed between 7 minutes and 25 minutes<br />

which is closely follows observed travel time<br />

distribution<br />

The error in observed and estimated travel time is<br />

about 7%.<br />

The average Planing Time Index value for the peak<br />

hour is about 4.25 for the observed travel time and<br />

it is 3.9 for simulated travel time<br />

Micro simulation models are capable to analyze<br />

the behavior of uncertain variable and better than<br />

the other aggregated models<br />

Influence of Demand Side Variation on Travel Time<br />

•<br />

•<br />

•<br />

•<br />

•<br />

The influence of traffic flow on travel time is<br />

estimated for 50 % increasing and 50 % decrease<br />

to the existing traffic demand<br />

If 50% traffic demand situation arises, road users<br />

should plan their travel for about 5.5 times of travel<br />

time as against free flow travel time.<br />

If the demand reduced by 50%, the PTI also<br />

reduced to 2.3.<br />

PTI value are as high as around 7.4 was observed<br />

for the period between 9.45 AM to 10:00 AM during<br />

the peak hour period.<br />

Whereas in the case of 50% less demand, PTI<br />

value is 2.6 for the period between 9:15 AM to 9:30<br />

AM<br />

Influence of Supply Side Variation on Travel Time<br />

•<br />

•<br />

Road under working are defined in the VISSIM as<br />

an event that effect or impeded the normal traffic<br />

flow at identified location (considered 200 mts)<br />

If the one lane is blocked for 30 minutes during the<br />

peak hour, road users should plan about 6 times of<br />

travel time as against free flow travel time.


72<br />

•<br />

If extra one lane is provided for the entire corridor,<br />

road users should plan about 3 times of travel time<br />

as against free flow travel time<br />

Influence of Signal Failure on Travel Time<br />

•<br />

With Signal the average Travel time is 17.51 minutes<br />

and if the signal is failure, the average travel time is<br />

about 25 minutes for the study corridor<br />

Further Findings/Conclusions/Supporting Data<br />

As per the Cost model, the fixed cost for ordinary bus<br />

per day is 2685/- to be assigned to 957 passengers<br />

travelling in ordinary buses per day, which comes to<br />

2.78/-. The variable cost of operation is estimated as `<br />

0.54 per passenger kilometer. Thus the total fare rate<br />

for a distance of 5 km (first fare stage) works out as ` 5.<br />

This can be rounded as ` 5.50 and fixed as rate for the<br />

minimum fare. On an average 717 passengers are found<br />

to be travelling in intercity fast/express bus services per<br />

day per bus. The average occupancy is found as 40.<br />

The fare for travelling minimum 10 kilometres works<br />

to be 7.28. Hence it is recommended that a minimum<br />

fare of 7.00 can be fixed for fast services and 10.00 for<br />

express services.<br />

Scope and Objective<br />

Plastic products used in Road safety Barrier like traffic<br />

delineators, safety barriers, cones etc. need to be<br />

specified in terms of capacity, dimensions, raw material<br />

specification, thickness, approx. weight etc. so as to<br />

avoid monopolistic approach and to protect the usage<br />

of sub-standard raw material, lookalike light weight<br />

products etc. This shall also determine no compromise<br />

at quality front & would be in the best interest of<br />

civic society. There also emerges the strong need<br />

to locate temporary road safety barriers on highway<br />

under construction, 4 lane to 6 lane conversions and<br />

Rural roads which could offer road safety to the<br />

satisfaction.<br />

The main of this study are<br />

•<br />

•<br />

To attract the kind attention of key decision makers<br />

to specify, standardize the technical specification<br />

of Road Safety Barrier (Plastic) prior deployment<br />

on road sites, study & underline the salient features<br />

to draw differential benefits<br />

Quick temporary arrangement to offer road safety<br />

on new highway projects to replace efficiently<br />

the use of traditional mud/soil filled sacs as per<br />

contemporary safety solution<br />

• To work on standardization of effective temporary<br />

road safety plastic barrier systems.<br />

•<br />

To place the Crash Tested Road Safety Plastic<br />

Barrier System on heavy traffic zone for performance<br />

assessment, the suitability of system under varying<br />

climate conditions<br />

Interim Conclusions/Conclusions/Supporting Data<br />

The traditional safety options are insufficient for such<br />

roads which deploy no other traditional means whether it<br />

is latest technology for road development, Engineering,<br />

Enforcement etc. is concerned. The increasing traffic<br />

congestion has made it requisite to seriously look into<br />

ROAD RESEARCH IN INDIA 2011-12 77<br />

temporary road safety solutions for <strong>Highway</strong>s & Rural-<br />

Urban <strong>Roads</strong>. Performance evaluation of barrier system<br />

was carried out through Crash Test on a trial stretch<br />

at Badhkal Circle, Faridabad as a temporary median<br />

adjoining NH-2. The errant vehicle crashed with the<br />

water filled crash tested barrier system and following<br />

observations were noted:<br />

eValUatIon CrIterIa reSUltS aCHeIVeD<br />

Crash barrier shall contain &<br />

redirect the vehicle. the vehicle<br />

shall not penetrate, under ride<br />

or override the installation.<br />

Controlled lateral deflection of<br />

plastic barrier is acceptable.<br />

Detached elements or debris<br />

from the plastic barrier should<br />

not penetrate or show potential<br />

for penetrating the occupant<br />

compartment.<br />

Shall not present an undue hazard<br />

to other traffic, pedestrians<br />

or personnel in a work zone.<br />

The vehicle should remain upright<br />

during & after collision.<br />

After collision it is preferable<br />

that the vehicle’s trajectory<br />

not intrude into adjacent traffic<br />

lanes.<br />

Significance/Utilization Potential<br />

Vehicle contained & redirected.<br />

Almost nil lateral deflection.<br />

<strong>No</strong> evidence of any potential<br />

of intrusion of<br />

detached article was<br />

found.<br />

<strong>No</strong> undue hazard was<br />

found to the other traffic,<br />

pedestrians or personnel<br />

in a work zone.<br />

Vehicle remained upright.<br />

Vehicle came to rest<br />

close to the barrier. <strong>No</strong><br />

potential of intruding into<br />

adjacent traffic lanes.<br />

There is a significant application to introduce such<br />

temporary barrier systems on highways as well which<br />

could render support to preclude the accident injuries<br />

and fatalities involved.<br />

In fact, to motivate & promote standard code of<br />

practices, all the present temporary barricading system<br />

like cones, plastic barricades etc. should have material,<br />

properties, dimensions, color, approx. weight, water<br />

capacity, level indicator to ensure the product behavior<br />

as road safety product and it needs to be redefined.<br />

This shall bring a pause to sub-standard utilization<br />

of raw material, practices & protect the compromises<br />

made if any in terms of quality of road safety products.<br />

The huge utilization potential is evident & need no<br />

introduction in present scenario. We see the huge scope<br />

of remedial actions to be yet taken at the forefront of<br />

introducing these temporary road safety contemporary<br />

measures on rural & urban highways/roads under<br />

development or near future projects of Central & State<br />

owned planned developments.<br />

On above lines, we installed our crash tested water<br />

filled road safety plastic barrier system in conjunction


78<br />

with Traffic Police Department, Faridabad at an<br />

identified location which has serious requirement of<br />

placing some temporary road safety barrier system<br />

as a median to stop the infiltration of either side traffic<br />

while without compromising the road safety aspects.<br />

This traffic junction is critical since the traffic load is<br />

pretty heavy & accident chances are prominent<br />

The results are astonishing, the demarcation is great,<br />

accident occurred but the injuries were nil, system<br />

debris was nil, clear traffic movement continued post<br />

accident, vehicle dents were reduced, occupants were<br />

safe etc. This is significant & establishes that such<br />

systems are to be ideally encouraged & proposed for<br />

all traffic applications whether it is traffic delineation or<br />

excavated road site protection on highways, urban &<br />

rural areas.<br />

The wide usage of traditional woven sacks filled<br />

with sand as temporary marking of work under<br />

progress or light weight plastic cones / light weight<br />

water ballasted other plastic barricades has also<br />

imposed limitations during project execution.<br />

The Cosmos Crash Tested Barrier installed at<br />

Badhkal Circle as median has demonstrated only<br />

a piece of application; the appropriate application<br />

is highway roads with work under progress where<br />

we wish to carry it for road safety application in our<br />

further work.<br />

Recommended to be installed at all work zones<br />

where road development projects are to be initiated,<br />

are in full swing, semi-finished road sites, gaps<br />

created on medians, exposed excavated roads on<br />

highways, V.I.P pockets for temporary diversions,<br />

Consulates, Airports etc.<br />

Development of standard code of practices for all<br />

the temporary barricading system like cones, plastic<br />

barricades, crash tested barriers etc. should have<br />

material, properties, dimensions, color, approx.<br />

weight, water capacity, level indicator to ensure<br />

that product meets the specific definition of road<br />

safety product.<br />

To study the accident trend in Kerala.<br />

To analyse the accidents pertaining to K.S.R.T.C.,<br />

private, and institutional buses.<br />

To study safety practices of different type of public<br />

transport buses.<br />

To analyse the safety attitude of bus drivers and<br />

To study the bus condition with respect to safety of<br />

passengers.<br />

Methodology<br />

i.<br />

i.<br />

ii.<br />

Primary and Secondary data are to be collected<br />

to study the accident situation in Kerala. It is also<br />

required to study the part of buses in accidents.<br />

Interview of bus drivers are to be conducted to<br />

understand the road safety awareness of them and<br />

their attitude towards it.<br />

Sample Survey of Buses is to be conducted in<br />

order to realize the operational condition of buses<br />

like age and other aspects.<br />

Interim Conclusions/Conclusions/Supporting Data<br />

Public transportation services are the way to transport<br />

large number of passengers at a relatively low cost on<br />

a relatively fixed route at scheduled times. The public<br />

transportation system in Kerala includes Road, Rail,<br />

Air, and Water transportation. Road transportation<br />

is one of the major modes among these. Buses, the<br />

mode of Public transportation system through roads<br />

comprise two types: Stage carriages and Contract<br />

carriages. Stage carriages like K.S.R. T. C buses and<br />

private buses are having an important role in road<br />

transportation. Institutional buses are coming under<br />

contract carriages. While going through the overall<br />

accident data and matters relating to that in Kerala,<br />

it is clear that the buses are having an unavoidable<br />

role. So, it is required to study the causes and related<br />

factors of bus accidents in detail. Safety aspects of bus<br />

passengers are also need to be studied.<br />

<strong>No</strong>w the study is conducted for Thiruvananthapuram<br />

and Kozhikode districts. Through this study, the present<br />

condition of buses, bus depots, bus stops, driver and<br />

conductor behaviours etc. revealed. According to


study, the condition of most of the buses and bus stops<br />

are very bad. They are not having adequate facilities.<br />

Most of the bus accidents occur due to brake failure<br />

and axle breakdown, so mechanical condition of buses<br />

should also be considered. There should be methods<br />

to assess the suitability of bus crew by means of their<br />

mental and physical ability. Proper training also should<br />

be given to the crew members.<br />

Centre - (R)<br />

Scope and Objectives<br />

a)<br />

b)<br />

c)<br />

d)<br />

To collect the accident details pertaining to the past<br />

three to four years.<br />

To analyze the accident causative factors.<br />

To evolve a suitable methodology to confine the<br />

accident prone locations.<br />

To carry out a micro- level analysis of the accident<br />

prone locations under safety auditing.<br />

Methodology<br />

Road accidents have occurred due to the increase<br />

in motor vehicles and the corresponding inadequacy<br />

of road infrastructure developments. Therefore a<br />

practical solution is necessary by identifying the facts<br />

as it featured alignment drawbacks too.Accident data<br />

has a prominent role in establishing the factors causing<br />

accidents and in order to control, regulate and manage<br />

the problem, an effective support relied on the matters<br />

of previous occurrences are found extremely helpful<br />

to substantiate the proximity towards accidents at the<br />

locations identified.<br />

ROAD RESEARCH IN INDIA 2011-12 79<br />

Data Collections: Three types of data such as Accident<br />

frequency and characteristics, Geometric features of<br />

the road and traffic data have been collected.<br />

By using the data following methods have been applied<br />

to determine accident prone locations.<br />

•<br />

•<br />

•<br />

Quantum of Accident Method was adopted i.e.<br />

higher the number of accidents on any stretch,<br />

higher would be the accident proneness of that<br />

stretch.<br />

Two accidents in a year may be due to minor<br />

design defect while three or more accidents in<br />

a year definitely indicate serious deficiencies in<br />

Geometrics of the road stretch.<br />

Estimated Accident Risk Index (ARI) consisting of<br />

Consistency, Tendency and level of accidents.<br />

The three components of accidents have been formed<br />

into groups with assigned scores based on number of<br />

accidents occurring in a year. later identified stretches<br />

of one kilometre were put under a Road Safety<br />

Auditing.<br />

Interim Conclusions/Conclusions<br />

Identification of accident prone locations and<br />

improvement measure packages will be useful to<br />

Public Works Department and local authorities<br />

including District Administration, Police, Motor Vehicle<br />

Department and Stakeholders in road safety.<br />

Analysis of Driver Behaviour and Crash<br />

Characteristics<br />

Conditions<br />

during Adverse Weather<br />

Date of Start: May 2012<br />

Date of Completion: May 2014<br />

CSIR- Central Road <strong>Research</strong> Institute, New<br />

Delhi (R)


80<br />

Scope and Objectives<br />

•<br />

•<br />

•<br />

To capture drivers visual and measurable fatigue<br />

during fog driving under simulated environment<br />

and realistic setting.<br />

To investigate and analyze drivers’ choice of<br />

headway and speed in fog under simulated<br />

environment and realistic setting.<br />

To investigate if the choice of speed and headway<br />

are affected by the vehicle they drive or follow (under<br />

simulated environment and realistic setting).<br />

Methodology<br />

This study will be conducted in two parts<br />

a)<br />

b)<br />

The observation and analysis of driver’s R.T. and<br />

other behaviour in laboratory setting: In this part<br />

different psycho physical tests along with the<br />

skill tests will be conducted in driving simulator<br />

to analyze in simulated rainy and fog condition<br />

the driver’s behaviour e.g. crash characteristics,<br />

risk taking practices, reaction time etc The driving<br />

simulator will be used to obtain behavioural data<br />

from the drivers of different age groups under<br />

simulated adverse weather condition.<br />

The observation and analysis of driver’s R.T.<br />

and other behaviour in field setting (in adverse<br />

weather): In this part of the test will be conducted<br />

during rainy seasons and in the winter settings<br />

under fog condition to observe the driver behaviour.<br />

In continuation of this driver’s characteristic will be<br />

measured with the help of the V-Box and with the<br />

three cameras to measure driver’s reaction time,<br />

behavioural movements and road assests during<br />

the acquisition.<br />

Finally Real World Data will be processed for modelling<br />

during the all seasons. An evaluation of relationships<br />

between age, personality and driving style will reveal<br />

the relationship between the driver age and type A<br />

or B personality characteristics and which type of<br />

personality is a good predictor of vehicle speed and<br />

following distance. A factor analysis of several at-risk<br />

driving behaviours will be identified a cluster of correlated<br />

driving behaviours that appeared to share a common<br />

characteristic identified as aggressive/impatient driving.<br />

This correlated cluster of driving behaviour will provide<br />

objective support for the assumptions of response<br />

generalization and problem behaviour theory. Results<br />

will be discussed with regard to implications for safe<br />

driving interventions and a suggesting remedial for<br />

problem behaviour syndrome.<br />

Significance/ Utilization Potential<br />

Significant part of the project would be obtaining driver<br />

behavioural data at reverse weather conditions. The<br />

GENERAl REPORT ON<br />

study will also focus on crash modelling in fog, which<br />

will provide insight about possible damages and<br />

injuries in fog related crashes. The final project report<br />

will address the answers of the four research questions<br />

identified in this study. Specifically there will be findings<br />

related to drivers’ state, their car following behaviour<br />

as well as type and pattern of crashes in fog. Based on<br />

these findings the research team will also recommend<br />

ways by which frequency and severity of incidents<br />

can be reduced by providing drivers with enough<br />

information about the roadway and traffic conditions as<br />

well as through better traffic management in fog. Study<br />

is under progress.<br />

Scope and Objectives<br />

•<br />

The aim of the project is to assess the ambient air<br />

quality and noise levels in and around the proposed<br />

IISER construction site as the part Environmental<br />

Impact Assessment (EIA) study.<br />

ROAD RESEARCH IN INDIA 2011-12 81<br />

Methodology<br />

•<br />

•<br />

Measure the concentration of air pollutants such as<br />

particulate matter, Nitrogen dioxide (NO ), lead (Pb),<br />

2<br />

Carbon Monoxide (CO) and Ammonia (NH ) at five<br />

3<br />

locations at proposed IISER Campus as per CPCB<br />

guidelines with varying number of anthropogenic<br />

sources. The measurement will be done in four<br />

seasons such as Season I (June-August), Season<br />

II (September-<strong>No</strong>vember), Season III (December-<br />

February) and Season IV (March-May).<br />

Measure the <strong>No</strong>ise level at five locations during<br />

four seasons in and around IISER Campus with<br />

the guidelines of International Electro Technical<br />

Commission (IEC).<br />

Interim Conclusions/Conclusions/Supporting Data<br />

The concentration of particulate matter and carbon<br />

monoxide at two sampling stations namely Physical<br />

Science Building and Main Plant are closer to the<br />

prescribed limit of CPCB standards may be due to the<br />

continues operation of concrete mixture plant, Diesel<br />

Power Generator and vehicular movement. But the<br />

overall result shows that the pollutant levels are within<br />

the permissible limit.<br />

Significance/Utilisation Potential<br />

After construction, the air quality and noise levels will<br />

be under the prescribed standards. The green belt of<br />

Ponmudi hills will serve as the best absorbent of both<br />

air and noise pollution in this area.<br />

Limitations of Conclusions/ further proposed work<br />

The construction of IISER campus is under progress.<br />

It is suggested that the monitoring of air pollution and<br />

noise levels should be monitored until the completion<br />

of the construction work.<br />

Conclusions<br />

The study findings and appropriate recommendations<br />

evolved in this study are briefly summarized below:<br />

•<br />

•<br />

•<br />

The monorail alignment proposed from Technocity<br />

(Pallipuram) to Neyyattinkara.The total distance<br />

of the proposed project stretch is about 41.8 km.<br />

The route of alignment is “Pallipuram (Technocity)<br />

– Kazhakoottam – Ulloor- Kesavadasapuram –<br />

Pattom – lMS- Palayam – Statue – Overbridge<br />

–Thampanoor – Killipalam – Karamana –<br />

Pappanamcode – Balaramapuram – Neyyattinkara”<br />

and is proposed to be implemented in two phases.<br />

The Financial Internal Rate of Return (FIRR) has<br />

been computed by using the revenue and cost<br />

streams with a conservative and optimum fare<br />

structure. Financial analysis shows that FIRR<br />

varies from 7% to 13% depends on the various<br />

scenarios adopted for the feasibility study<br />

The economic evaluation of the project corridor<br />

has been carried out by applying the Social Cost-<br />

Benefit Analysis Technique. The technique uses the<br />

incremental costs and benefits under the ‘with’ and


‘without’ project scenarios. The Economic Internal<br />

Rate of Return (EIRR) for the project computed<br />

using Discounted Cash Flow technique showed<br />

the value of 12.6%.<br />

Scope & Objectives<br />

The night accidents are the results of the fact that<br />

headlights are involved in its occurrence directly or<br />

indirectly. Thus most of the fatal and serious injuries<br />

are sustained by drivers at night. This leads to the<br />

conclusion that an Anti Glare Barrier can go a long way<br />

towards safety enhancement and thus in reducing the<br />

fatality rate on roads at night. An Anti Glare Barrier will<br />

improve visibility by minimizing glare, a major cause<br />

of momentary loss of vision. The realization of the<br />

ultimate goal of total road safety through creating ideal<br />

Further findings/conclusions/supporting data<br />

M/s Ambuja Cements limited requested CSIR-Central<br />

Road <strong>Research</strong> Institute to carry out air pollution and<br />

traffic studies to predict the impact on air quality of the<br />

road network in the influence area which are likely to<br />

be affected due to the expansion of one of its cement<br />

plant at village Rauri, Darlaghat (H.P) (clinker capacity<br />

increasing from 1.8 MTPA to 2.6 MTPA) and a new<br />

grinding unit at village Panjehra in Nalagarh (H.P)<br />

which is situated at a distance of about 20 km from its<br />

existing grinding plant at Ropar (Punjab).<br />

Air pollution measurement and traffic flow studies were<br />

carried out in order to evaluate the influence on air<br />

quality, air dispersion modelling (CAlINE 4 model) was<br />

attempted to obtain the base line information for the<br />

same. In addition, vehicular emission loads of CO, HC,<br />

NO x and PM at selected locations were estimated.<br />

Continuous measurements were carried out for these<br />

air pollutants at each of the selected locations on 24-hr<br />

basis by using CRRI’s sophisticated state-of-art mobile<br />

air pollution laboratory equipped with pollutant-specific<br />

automatic analyzers. To predict the CO concentrations<br />

along the road corridor(s), vehicular pollution modelling<br />

was carried out using CAlINE 4 model. The vehicular<br />

emission loads of CO, HC, NO x and PM) at selected<br />

locations (sites) were estimated for base year 2009<br />

and projected year 2012.<br />

ROAD RESEARCH IN INDIA 2011-12 85<br />

The Concentrations of most of the air pollutants<br />

at almost all the locations except for CO and PM at<br />

Nalagarh (Panjehra) did not exceed the ambient air<br />

quality standards as specified by CPCB. The CO<br />

prediction using CAlINE 4 model was carried out for all<br />

four pre-identified road corridors. The modelling results<br />

indicated that the predicted CO concentrations for the<br />

year 2012 were slightly higher as compared to the base<br />

year 2009. That was due to natural growth in the traffic<br />

volume and additional trucks that have increased after<br />

the capacity expansion of the plant were added for the<br />

projected year 2012.<br />

Vehicular emission load along the road corridors were<br />

calculated for CO, HC, NO x and PM. Vehicular emission<br />

loads were calculated for both the base year (2009)<br />

as well as for the projected year 2012. <strong>No</strong> significant<br />

change in total emission load and contribution from<br />

individual pollutant(s) in the projected year 2012 visà-vis<br />

base year 2009 was observed due to improved<br />

engine technology in the vehicles and fuel quality<br />

Study of <strong>No</strong>n methane hydrocarbons in the<br />

atmospheric environment of Delhi region<br />

Date of Start : Dec 2007<br />

Date of Completion : Jan 2012<br />

CSIR- Central Road <strong>Research</strong> Institute, New<br />

Delhi (R)<br />

present Status and progress<br />

Status: Completed<br />

The present study shows the following results. The<br />

proportion of propane is highest in traffic area i.e. 98%<br />

followed by ethane (2%). Butane shows a negligible<br />

concentration in this area. The results show that the<br />

only expected source of propane is traffic in the ambient<br />

air. Traffic congestion is the main problem which<br />

leads to increased concentration of propane. First<br />

Traffic sampling site, i.e. Ashram intersection shows<br />

the highest and abnormal concentration of propane.<br />

The probable reason is the traffic congestion on the<br />

intersection area. Most of the time vehicle is in idling<br />

mode and in this condition there are more chances to<br />

get an incomplete combustion of CNG (Compressed<br />

Natural Gas) yielding plethora of propane.<br />

In the second traffic sampling site, i.e. Dhaula Kuan<br />

there was a moving traffic and least congestion was<br />

present at the time of sampling which is reflected in the<br />

results. So it was concluded that the high concentration<br />

of propane may be attributed to the incomplete<br />

combustion of CNG in the internal combustion engine.<br />

The pattern of the NMHCs is more or less similar in<br />

commercial area and residential area. The probable<br />

reason of this could be the close proximities of<br />

commercial and residential areas in Delhi.In commercial<br />

area the shopkeepers usually uses petromax for lighting<br />

GENERAl REPORT ON<br />

in case of power failures. These petromax are not very<br />

well maintained and so there is always a probability of<br />

leakage during usage, also the filling of these petromax<br />

is usually done from lPG cylinders which results in<br />

leakage of lPG in atmosphere. This lPG could be<br />

the probable source of high concentration of ethane<br />

in these commercial areas. Commercial sampling site<br />

(C2) had a restaurant in the vicinity of sampling place<br />

which uses lPG.<br />

The results show that in residential area also<br />

concentration of ethane is maximum. This could also<br />

be attributed to the lPG leakage in houses. lPG is<br />

normally used in residential areas for cooking purposes.<br />

Residential sampling site like Maharani Bagh have<br />

underground lPG pipelines even any small leakage<br />

during handling and usage can increase concentration<br />

of ethane in ambient air.<br />

The maximum contribution of butane comes from<br />

industrial areas i.e. 47% and also if individual results<br />

for distribution of NMHCs in industrial areas are<br />

speculated it was observed that ethane shows a<br />

maximum contribution. This scene could be realized if<br />

the various industrial activities like welding, usage of<br />

solvents etc. are taken into account.<br />

Satyam Puram, Jharoda Kalan Border which was taken<br />

as a background area is nearly undeveloped rural area<br />

which has no industrial or commercial activities going<br />

on nearby. Since it is a rural area not very good traffic<br />

facilities are present. All these conditions made this<br />

zone a completely pollution free area which is reflected<br />

in the results thereby proving a very good background.<br />

Further findings/conclusions/supporting data<br />

The study dealing with NMHCs in Ambient Air<br />

described above is concluded on the following<br />

grounds The concentrations of NMHCs in Commercial,<br />

Residential, and industrial Area shows a similar order<br />

Ethane>Propane>Butane even though the butane is<br />

contributed to a maximum extent by Industrial Areas<br />

(47%) followed by Residential Areas (29%), Commercial<br />

Areas (14%) and Traffic Area (7%). A different pattern<br />

is observed for distribution of Ethane with following<br />

percentage composition viz. Residential Areas (40%),<br />

Industrial Areas (<strong>39</strong>%), Commercial Areas (14%) and<br />

Traffic Area (10%). Propane showed a monopoly in<br />

the Traffic Areas with a negligible contribution in other<br />

areas.<br />

recommendation for further work<br />

We propose the following which can be done in this<br />

regard<br />

•<br />

Altitudinal profiling of NMHCs in the various areas<br />

viz. Traffic Areas, Residential Areas, Commercial<br />

Areas, and industrial Area.

V. RESEARCH PROJECTS RELATED TO THESIS FOR<br />

POST- GRADUATION/ Ph.D<br />

a. paVeMent enGIneerInG anD MaterIalS<br />

SUMMarY<br />

The various research topics related to thesis work include pavement management and maintenance systems for<br />

highways and rural roads, deterioration models, design analysis for composite layered pavements, pervious concrete<br />

pavements, use of RBI grade 81and coir geo-textiles for improving performance of pavements, and development of<br />

rutting model for bituminous pavements.<br />

It has been concluded that 25mm SDBC overlay at an earlier stage is better than 40mm BM at a later stage. Network<br />

level Pavement Maintenance Management Using Road Network Evaluation Tool (Ronet) has revealed that the<br />

maximum benefits are obtained if higher threshold standards and thicker overlays are selected to ensure that the<br />

selected road network always remains in good condition.<br />

In case of low volume rural roads the clustering can be used in categorizing the pavement sections for efficient<br />

rural road maintenance management. From the optimisation results, it is seen that in the necessary fund model, the<br />

minimum budget required to keep the pavements in a specified threshold level is less for the clustered pavement<br />

sections than that for the unclustered sections.<br />

Investigating the role of Activity Characteristics, Spatial Variation and Timing Dimension in Trip and Tour Frequency<br />

Models, it has been observed that Activity based trip frequency models perform better than the conventional trip<br />

frequency models. Trips were found to vary across the different zones. Incorporating spatial effect increased the<br />

goodness-of-fit of the trip frequency models significantly.<br />

Study of pervious concrete has revealed that compressive strength of pervious concrete is <strong>39</strong>% less than normal<br />

concrete. Split tensile strength is 15% less than normal concrete. Modulus of rupture of pervious concrete is 22% less<br />

than normal concrete. The average co-efficient of permeability was found to be 0.155 cm/sec<br />

Stabilization of soil with RBI Grade 81, phosphogypsum and ecobase stabilizers resulted in decrease in PI value<br />

and increase in CBR, ultimate tensile strength and fatigue strength of the soil. 400 GSM woven geotextile placed at<br />

bottom position of the overlay specimen showed maximum decrease in rut deformation compare to control specimen.<br />

Geotextile placed at bottom of overlay performed better than geotextile placed at one-third from bottom in the overlay<br />

followed by geotextile placed at middle in the overlay.<br />

The research topics covered in various thesis work are aging behaviour of bitumen with different fillers, Dynamic<br />

Mechanical Analysis and Development of Master Curves for Bitumen Processed in India, Recycled Asphalt<br />

Pavement, Foamed Bitumen, Stone Matrix Asphalt, Bituminous Concrete Using Treated Aggregates, Pavement<br />

Design Evaluation and Back analysis using Markov chain Monte Carlo Simulation, Bituminous Mix with Added Fibres,<br />

life-Cycle Cost Analysis of long lasting Pavements, Evaluation of Flexible Pavement by Kenpave Software for the<br />

Blended Soils, and Mix Design of Pervious Concrete.<br />

It has been concluded that So in terms of aging, for VG 20 grade bitumen, it is better to use cement added at 1%<br />

as filler material and for VG 10 grade bitumen fly ash and lime added at 2 and 1.5% can be used as filler material.<br />

Fatigue life of SMA mix prepared with PMB 40 was 5.19% greater than that of SMA mix prepared with PMB 70.<br />

Stiffness modulus and surface characteristics of bituminous mixes can be enhanced by adding fibers. Bituminous<br />

mix with Coir fiber shows better structural and creep characteristics than mix with other fibers. The study shows that<br />

although the concept of perpetual pavements advocates the increase of HMA thickness to keep the critical strains<br />

within the threshold limits, the provision of a stable foundation and the high stiffness base materials are equally<br />

significant from a financial perspective.

Optimal maintenance option for each project road<br />

section results in low maintenance cost with desired<br />

performance for the design period of 15 years.<br />

Delay in the maintenance application increases<br />

the maintenance cost approximately two times for<br />

every year of delayed maintenance. This leads to<br />

increase in Vehicle operating cost.<br />

Timely application of appropriate maintenance<br />

option controls the roughness, pothole and cracking<br />

progression within the intervention limits, whereas<br />

in case of base alternative, roughness reaches the<br />

maximum limit.<br />

Adopting periodic-preventive maintenance for all<br />

the pavements when they are in good condition<br />

increases the benefits for agency and road users.<br />

Under budget constraint scenario, the suggested<br />

analysis is helpful for the prioritization of the road<br />

projects for maintenance.<br />

Compilation of data: The following data on the road<br />

network is collected and compiled.<br />

Traffic data<br />

Pavement condition data<br />

Roughness data<br />

The extent and severity of various distresses<br />

obtained from the pavement condition data are<br />

combined into an index called the pavement<br />

condition index (PCI) using the deduct value<br />

method.<br />

The network is then classified into homogeneous<br />

sections based on traffic levels, pavement condition<br />

index (PCI) and International Roughness Index<br />

(IRI).<br />

Performance of pavements is predicted using<br />

the Markov method wherein transition probability<br />

matrices are developed for different scenarios.<br />

Various maintenance strategies are identified<br />

based on the IRI threshold levels and the overlay<br />

thicknesses. The costs and benefits for an analysis<br />

period of 20 years at a discount rate of 12% are<br />

computed and compared for all the strategies.<br />

Benefit/cost ratio is used as an economic indicator<br />

to find the optimal strategy that leads to minimization<br />

of any combination between agency costs and<br />

road user costs and the maximization of the whole<br />

network quality or performance subject to annual<br />

budget constraints.


Salient-Findings and Conclusions<br />

The study is conducted to decide an optimal threshold<br />

standard as well as optimal overlay thickness for 1646<br />

km of roads divided based on traffic and pavement<br />

condition. The costs and benefits of various strategies<br />

are computed for 20 year analysis period, discounted<br />

at a rate of 12% and compared.<br />

2.<br />

3.<br />

The maximum benefits are obtained if higher<br />

threshold standards and thicker overlays are<br />

selected to ensure that the selected road network<br />

always remains in good condition. Highest benefits<br />

are obtained if BC overlay of 100 mm thickness<br />

is adopted at very high threshold standard at an<br />

agency cost of Rs. 835crores (167M$).<br />

For an unconstrained budget scenario, adopting a<br />

BC overlay of 75 mm thickness at an agency cost<br />

of Rs.700 crores (140M$) is found to be optimal. A<br />

very high threshold standard is considered for all<br />

traffic classes.<br />

For a constrained budget scenario, the following<br />

strategies can be adopted as per the availability of<br />

funds. For a constrained budget policy, the scenario<br />

with the greatest NPV/cost need to be selected that<br />

gives the highest returns for the amount spent.<br />

•<br />

•<br />

If 75% of Rs. 835 crores (167M$), i.e. Rs. 625<br />

crores (125M$) is only available, adopting<br />

an BC overlay of 40 mm thickness for roads<br />

in good and fair condition and BC overlay of<br />

75 mm thickness for roads in poor condition<br />

at an agency cost of Rs. 595 crores (119M$)<br />

is found to be optimal. The overlay serves as<br />

preventive maintenance for the roads in good<br />

condition and as corrective maintenance for<br />

the roads in fair condition.<br />

If only 50% of Rs. 835crores (167M$), i.e. Rs.<br />

415crores (83M$) is available, adopting a BC<br />

overlay of 25 mm thickness for roads in good<br />

and fair condition and BC overlay of 75 mm<br />

thickness for roads in poor condition at an<br />

agency cost of Rs. <strong>39</strong>0 crores (78M$) is found<br />

to be optimal.<br />

4. A minimum of Rs. 295 crores (59M$) is required to<br />

provide a BC overlay of 25 mm thickness at a very<br />

low threshold level.<br />

5. Decision Support System for Maintenance<br />

Management of Low Volume Rural <strong>Roads</strong><br />

Date of Start and Duration: 20.07.2007<br />

<strong>Indian</strong> Institute of Technology Madras, Chennai<br />

- 600 036<br />

Scope and Objectives<br />

The following objectives are pursued in this research:<br />

•<br />

•<br />

•<br />

•<br />

Formulation of indices for pavement condition<br />

rating using factor analysis<br />

Cluster analysis application in rural road<br />

maintenance management<br />

Development of performance prediction models for<br />

low volume rural roads<br />

Development of a decision support system for<br />

optimal maintenance of low volume rural roads<br />

Proposed Methodology<br />

The management of low volume rural roads in<br />

developing countries presents a range of challenges to


oad designers and managers. Rural roads comprise<br />

over 85 percent of the road network in India and their<br />

being kept in serviceable condition is crucial to rural<br />

economy. The present study aims at developing an<br />

optimum maintenance strategy for the rural roads under<br />

rural road programme namely Pradhan Mantri Gram<br />

Sadak Yojana in Tiruchirappalli District, Tamilnadu in<br />

India. Visual condition survey of the selected roads<br />

which includes condition of shoulders, drains, cross<br />

drainage structures, and camber; and pavement<br />

distresses viz., potholes, crack area, edge break are<br />

collected in 2009, 2010 and 2011. GPS coordinates<br />

and photographic images depicting the condition of the<br />

pavement are taken at every 200 m interval. An index<br />

namely Visual Condition Index is formulated from the<br />

above measured parameters based on factor analysis.<br />

This study also aims at investigating the efficacy of<br />

using cluster analysis as an aiding tool for Pavement<br />

Management System. K-means and latent Class<br />

Clustering were conducted for grouping the pavement<br />

sections into homogeneous clusters. Deterioration<br />

models were development for clusters separately.<br />

linear regression models relating VCR with age<br />

were developed for clustered and unclustered data.<br />

Optimisation of maintenance strategies were done in<br />

GAMS. Both the budget bound and necessary fund<br />

scenarios were considered for optimization with the<br />

models with and without cluster.<br />

Salient-Findings and Conclusions<br />

The results obtained from the work reveals that the<br />

clustering can be used in categorizing the pavement<br />

sections for efficient rural road maintenance<br />

management. From the optimisation results, it is seen<br />

that in the necessary fund model, the minimum budget<br />

required to keep the pavements in a specified threshold<br />

level is less for the clustered pavement sections than<br />

that for the unclustered sections. Also, in budget<br />

bound condition, the total effectiveness (area under<br />

performance curve) are with the clustered modelled<br />

pavement sections.<br />

6. Development of Pavement Deterioration<br />

Model for the Road Networks of Trivandrum<br />

Date of Start: August 2011.<br />

Date of Completion: August 2012.<br />

College of Engineering, Trivandrum (R)<br />

ROAD RESEARCH IN INDIA 2011-12 95<br />

Scope and Objectives<br />

The quality and efficiency of road network affects the<br />

quality of life, the health of the social system, and<br />

the continuity of economic and business activities of<br />

a country. Maintenance and up gradation of such a<br />

large network is a challenging task because of the<br />

logistics and constraints of resources. There is a need<br />

to manage the network more efficiently in a scientific<br />

manner. Pavement Maintenance and Management<br />

System(PMMS) can be defined as a scientific tool<br />

for managing the pavements so as to make the best<br />

possible use of resources available or to maximize<br />

the benefit of society. A well-designed geographic<br />

information system (GIS) provides a platform on<br />

which all aspects of the PMMS process can be built.<br />

A comprehensive GIS includes procedures for data<br />

input, either from maps, aerial photographs, satellites,<br />

surveys or other sources; data storage, retrieval, and<br />

querying; data transformation, analysis, and modelling;<br />

and output generation, including maps, reports, and<br />

plans.<br />

The development of a strong database is the primary<br />

part of any PMMS.The Dynamic Segmentation (DS)<br />

capability of a GIS can be used to enhance PMMS.<br />

Dynamic segmentation has allowed for increased<br />

accuracy of the PMMS as the data can be displayed<br />

to closely reflect the changing condition of a pavement<br />

segment. Application of pavement maintenance<br />

management systems requires the ability of system<br />

to predict future pavement conditions. Modeling of<br />

pavement performance deterioration in terms of riding<br />

comfort or pavement roughness and surface distress is<br />

a critical engineering process in PMMS. As a primary<br />

component of a PMMS, dynamic performance prediction<br />

models are crucial for one or more of the following<br />

analyses: maintenance planning, budgeting, life-cycle<br />

analysis, multi-year optimization of maintenance works<br />

program, and authentication of design alternatives. The<br />

main focus of the study is to develop a dynamic hybrid<br />

pavement deterioration model from the database in<br />

ArcGIS. Four cycles of pavement condition data and the<br />

required inventory data are compiled from the ArcGIS<br />

database. In MATlAB a composite index get developed<br />

for every inspection period by coding. A deterioration<br />

model get developed to determine the pavement<br />

condition for ant time as a function of index of previous<br />

period, axle load, age of pavement, maintenance<br />

history and drainage details. The correlation between<br />

the road roughness and composite index developed<br />

also get determined.<br />

The developed model is illustrated considering the<br />

study corridor in Trivandrum city. The study network<br />

was delineated into homogeneous section of 500m<br />

and the composite index gets developed with respect<br />

to visual rating, riding comfort and free flow speed.

The model was developed to determine the present<br />

and future pavement condition. In this study strategy<br />

analysis is carried by Matlab coding and Hybrid Neural<br />

network. The testing of model with final dataset shows<br />

linear relation between actual and predicted values of<br />

pavement condition.<br />

Development of composite condition indices by<br />

fuzzy logic method and MATlAB Coding<br />

a.<br />

Development of composite index by fuzzy<br />

logic<br />

Fuzzy logic method can be used for<br />

estimating of pavement condition rating<br />

by giving factors as input variables and<br />

deduct value as output variable. Pavement<br />

condition rating is based upon visual<br />

inspection of pavement condition, free flow<br />

speed and by riding comfort. Although the<br />

relationship between pavement condition<br />

and performance is not well defined, there<br />

is a general agreement that the ability of a<br />

pavement to sustain traffic loads in a safe<br />

and smooth manner is adversely affected<br />

by the occurrence of distresses .For the<br />

condition rating by fuzzy logic, a model is<br />

established with input variables as visual<br />

pavement condition rating, riding comfort,<br />

and free flow speed. Visual rating is classified<br />

as excellent, v.good, good, fair, poor and<br />

v.poor. The free flow speed is classified as<br />

v.high, high, medium and low. The riding<br />

comfort is classified as v.good, good fair and<br />

poor. A range is assigned for each class as<br />

there is only crisp value input in fuzzy logic.<br />

Output variable will give the final pavement<br />

condition. Fuzzy logic is a heuristic method<br />

to obtain very good results. In the established<br />

model, triangular membership functions were<br />

trained using existing data.

b. Development<br />

of composite index by MATLAB<br />

coding<br />

The procedure consists of developing<br />

composite index in Matlab consists of giving<br />

input variables, pre processing of data by<br />

normalizing the input values, giving weightage<br />

to each input, sum the condition and finally<br />

post processing of data by normalizing the<br />

output values. Here also the input variables<br />

are visual rating, riding comfort and free<br />

flow speed. The classifications also remain<br />

same. But here the input variables remain as<br />

such i.e. class and crisp values without any<br />

conversion to get the output index.<br />

Development of dynamic hybrid deterioration<br />

model for pavement performance analysis<br />

•<br />

•<br />

•<br />

This module consists of development of<br />

deterioration model by MATlAB coding. The<br />

model get trained and tested in Neural Network<br />

training tool. The model inputs consist of both<br />

class and crisp values. The class input consists<br />

of condition rating such as good, fair etc. The<br />

crisp values are numeric values. Hence both<br />

type of data input is done here, it can be called<br />

as Hybrid Model.<br />

The database gets updated with respect to<br />

inspection period, and this dataset is a direct<br />

input to program, result gets changed with<br />

respect to it. As pavement condition is dynamic<br />

in nature, the result is also dynamic with<br />

respect to the database. Hence it can be called<br />

as dynamic model.<br />

Eventhough the training and testing is<br />

conducted in Neural Network Training tool,<br />

due to the MATlAB coding of direct input of<br />

both class and crisp values, it can be named<br />

as HNN (Hybrid Neural Network) instead of<br />

Artificial Neural Network.<br />

Determination of IRI value from roughness data<br />

The IRI value can be obtained using fifth wheel<br />

bump integrator and MERlIN. Bump Integrator<br />

gives speedily a quantitative integrated evaluation<br />

of surface irregularities on an electromagnetic<br />

counter. It gives the BI counts in cm/km. MERlIN<br />

device can be used for direct measurement of<br />

unevenness usually called Roughness or for<br />

calibrating other instruments like Bump Integrator.<br />

It is get converted to IRI in m/km with the calibration<br />

of MERlIN-D.<br />

Determine the correlation between the composite<br />

index developed and the International Roughness<br />

Index<br />

ROAD RESEARCH IN INDIA 2011-12 97<br />

The composite index for each inspection period can be<br />

developed from fuzzy logic (CI-1) and MATlAB coding<br />

(CI-2). The index values get compared with the IRI<br />

values and the correlation coefficients get determined.<br />

Findings/Conclusions<br />

Following conclusions were drawn<br />

•<br />

•<br />

•<br />

•<br />

•<br />

A strong database is created for pavement<br />

maintenance management of selected road<br />

network of Trivandrum city<br />

From the traffic data, the growth rate was<br />

calculated as 5.7% d VDF as 4.6. Classified traffic<br />

volume count has been noted for entire stretches.<br />

Comparison of pavement condition changes in all<br />

inspection periods has been done. Final pavement<br />

condition rating prove that in the selected network<br />

6% are in excellent ,42% in v.good, 49% in good<br />

and 3% in fair condition finally.<br />

Dynamic segmentation of road network in ArcGIS<br />

has been done by 500 m segmentation<br />

a.<br />

b.<br />

c.<br />

For easy accessibility of data on each segment<br />

of road network by click on to the particular point<br />

on screen. The display of each attribute gives<br />

us a sudden clear picture about its condition<br />

for any time.<br />

It gives the Graphical display of data trends<br />

which is an effective method of communication<br />

between the system and user.<br />

The dynamic segmentation enhancing PMMS<br />

output results more interpretable through<br />

dynamic color coding and sophisticated<br />

visualization techniques<br />

Developed two composite indices for representing<br />

pavement condition as a function of visual rating,<br />

riding comfort and free flow speed by fuzzy logic<br />

and Matlab coding. Two composite indices get<br />

developed by Fuzzy logic approach and BY<br />

MATlAB coding. For large scale database CI-2<br />

proves to be more efficient and effective.CI-1 needs<br />

crisp value inputs and input data for every segment<br />

is a tedious job. For each inspection periods for<br />

each segment we have to give inputs to get the<br />

output. But CI-2 can accommodate both class and<br />

increased from 2% to 49% whereas after addition<br />

of 5% grade 81 RBI the cbr value increased to<br />

59%.<br />

After addition of ecobase stabilizer the ultimate<br />

strength of soil was increased from 2.5 kg/cm2 to 7<br />

kg/cm2 for 3 day cured sample and 13 kg/cm2 for 7<br />

day and 15.9 kg/cm2 for 28 day cured sample.<br />

The strain at failure of specimen is more or less<br />

same even after addition of both stabilizers.<br />

From experimental studies it was found that as<br />

the stress ratio increases the number of repeated<br />

loads for specimen failure is decreasing.

11. Experimental Investigations on Modification<br />

of Subgrade Characteristics by Chemical<br />

Addictives and Effect of Coir Geotextile on<br />

Pavement Distress in Overlays<br />

Date of Start: August 2010.<br />

Date of Completion: August 2011.<br />

College of Engineering, Trivandrum (R)<br />

Scope and Objectives<br />

In today’s world, there is an ever increasing demand<br />

for construction due to population expansion and<br />

shortage of building materials. Utilization of various<br />

industrial wastes such as phosphogypsum not only<br />

solves environmental problems but also provides a<br />

new resource for construction industry. In the present<br />

study, an industrial by-product phosphogypsum has<br />

been used to improve the subgrade for pavement<br />

construction. About 5 tons of phosphogypsum are<br />

generated per ton of phosphoric acid production, and<br />

worldwide phosphogypsum generation is estimated to<br />

be around 100–280 Mt per year.<br />

One of the more serious problems associated with<br />

the use of thin overlays is reflective cracking. Many<br />

pavements, which are considered to be structurally<br />

sound after the construction of an overlay, prematurely<br />

exhibit a cracking pattern similar to that which existed<br />

in the underlying pavement. This propagation of an<br />

existing crack pattern, from discontinuities in the old<br />

pavement, into and through a new overlay is known<br />

as reflective cracking. This movement may be caused<br />

by either traffic loading (tire pressure) or by thermal<br />

loading (expansion and contraction). Because a number<br />

of variables are involved in the nature of reflection<br />

cracking, no solution for the complete prevention<br />

of crack propagation has yet been suggested. Only<br />

retardation of crack progress is the best solution<br />

strategy adopted so far. The commercial finite element<br />

package ABAQUS version 6.9 is used for the stressstrain<br />

analysis.<br />

In this study, an attempt has been made to study the<br />

effects of coir geotextiles reinforcement in asphalt<br />

phosphogypsum on subgrade soil. The objectives of<br />

the study are,<br />

•<br />

part 2<br />

•<br />

to subgrade soil on its properties.<br />

To find the improvement in California Bearing Ratio<br />

(CBR) strength and Unconfined Compressive (UCC)<br />

strength of subgrade soil using phosphogypsum.<br />

To make a comparative study of results obtained<br />

before and after the addition of phosphogypsum.<br />

To conduct laboratory experiments in order to<br />

determine the effects of coir geotextile, in the<br />

behaviour of asphalt overlays.<br />

Proposed Methodology<br />

Proposed methodology of work involves the following<br />

steps:<br />

•<br />

•<br />

•<br />

•<br />

Experimental investigation includes creep and<br />

recovery test, Flow number test, dynamic modulus<br />

test and dry wheel tracker test.<br />

Constitutive modeling of the material response will<br />

be carried out for linear regime in the experimental<br />

data and a non linear modeling will be carried out<br />

to predict the whole creep and recovery data.<br />

Rut prediction will be carried out using Mechanistic<br />

empirical pavement design guide.<br />

A qualitative comparison of the responses predicted<br />

will be carried out with the rut wheel test data.<br />

Salient-Findings and Conclusions<br />

Repeated creep and recovery experiments on<br />

bituminous concrete mixtures resulted in different three<br />

stage creep responses for mixes tested at different<br />

temperatures and confinement conditions. An empirical<br />

approach was used to classify the various stages of<br />

three stage creep curve. Here primary stage was<br />

modeled using a power law, secondary stage using<br />

a straight line and tertiary stage using an exponential<br />

function. Four types of creep curves were observed.<br />

Type I curve has distinct three stages. Type II has both<br />

primary and secondary stage, but the tertiary stage<br />

was not reached within the test duration. Creep curves<br />

having only primary stage till the end of the experiment<br />

duration was named as Type III. Type IV had a primary<br />

stage suddenly going to the tertiary stage without any<br />

distinct secondary stage.<br />

A three stage creep curve was observed for 2 % air<br />

void specimens when tested at both confined and<br />

unconfined condition at 55 o C. A 7 % air void specimen<br />

reached a tertiary stage when tested in the unconfined<br />

condition at 55 o C. However the material did not show<br />

any distinct region of secondary stage. Also, the 7 %<br />

air void specimen tested at confined condition could<br />

not reach a secondary stage in the experimental time.<br />

These observations highlights the requirement of<br />

testing a 7 % air void specimen at sufficiently long time<br />

at confined condition, so that the material response as<br />

experienced in the field can be properly captured.<br />

Aging Behaviour of Paving Grade Bitumen<br />

with Different Filler Material<br />

Date of Start and Duration : June 2011, 10<br />

months<br />

Date of Completion : March 2012<br />

National Institute of Technology Karnataka,<br />

Surathkal<br />

Scope and Objectives<br />

The main purpose of this study was to investigate<br />

the rheological behaviour of virgin and aged asphalt<br />

cement by addition of various filler materials which are<br />

readily available. The objectives of this research work<br />

are as follows:<br />

a)<br />

b)<br />

c)<br />

d)<br />

To obtain mixing and compaction temperatures of<br />

asphalt cement by adding various filler materials.<br />

To study viscosity – temperature behaviour of<br />

asphalt cement by adding various filler materials.<br />

To study aging behaviour of the asphalt cements<br />

with various filler materials.<br />

To study viscosity – temperature susceptibilities<br />

of virgin and aged asphalt cement mixes using<br />

Penetration Index (PI), Pen - Vis Number (PVN)<br />

and Viscosity – Temperature Susceptibility (VTS).<br />

Two plain bitumen of viscosity grade VG 20 and VG<br />

10 (equivalent to penetration grade 60-70 and 80-100<br />

respectively) were used for this research study. Four<br />

materials namely stone dust, cement, lime and fly ash<br />

were used as filler materials. These fillers were added<br />

at different percentages like 1, 1.5 and 2%.<br />

Rotational viscometer (Brookfield viscometer) was<br />

used to obtain viscosity values of bitumen binders at<br />

different temperatures filled with various filler materials.<br />

Viscosity test were conducted at temperatures ranging<br />

from 80 to 180°C. Mixing and compaction temperatures<br />

of different asphalt cement mixes were obtained using<br />

viscosity – temperature graphs .Short term aging<br />

was conducted by using thin film oven test to obtain<br />

aging characteristics of asphalt cement and how such<br />

pavements can be rapidly aged and evaluated in the<br />

laboratory.<br />

The penetration test is conducted at 4°C and 25°C to<br />

measure the consistency of paving asphalt cement.<br />

Penetration values are used to determine the<br />

temperature susceptibility of asphalt cements in terms<br />

of Penetration Index (PI), Pen - Vis Number (PVN) and<br />

Viscosity – Temperature Susceptibility (VTS).


Proposed Methodology<br />

Experimental studies were conducted in laboratory as<br />

mentioned above.<br />

Salient-Findings and Conclusions<br />

Following conclusions are made based on the results<br />

obtained in the present investigation:<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

Both in aged and unaged conditions for VG 10 and<br />

VG 20 grade bitumen, stone dust added at 2% have<br />

maximum mixing and compaction temperature<br />

compared to other filler materials. This is due to<br />

specific surface area of stone dust is lower than<br />

other filler materials.<br />

There is no much difference in mixing and<br />

compaction temperature for both binders, at aged<br />

and unaged conditions.<br />

From the results of retained penetration, for VG<br />

20 grade bitumen, cement added at 1% shows<br />

maximum stability against aging effect while lime<br />

added at 1% shows minimum stability against aging.<br />

Similarly for VG 10 grade bitumen, fly ash added at<br />

2%, shows maximum stability and cement added<br />

at 2%, shows minimum stability against aging.<br />

From the results of aging index, for VG 20 grade<br />

bitumen, lime added at 2% shows maximum<br />

increase in viscosity after aging process, but<br />

cement added at 1% has less effect on viscosity<br />

with aging.<br />

For VG 10 grade bitumen, fly ash added at 2%<br />

shows maximum increase in viscosity after aging<br />

process, but lime added at 1.5% has less effect on<br />

viscosity with aging.<br />

From penetration index value, for VG 20 grade<br />

bitumen, lime added at 2% is highly temperature<br />

susceptible whereas fly ash added at 1% is less<br />

temperature susceptible, at unaged and aged<br />

condition.<br />

From penetration index value, for unaged VG<br />

10 grade bitumen, lime added at 2% is highly<br />

temperature susceptible whereas cement added<br />

at 1% is less temperature susceptible. Similarly<br />

for aged bitumen, fly ash added at 2% is highly<br />

temperature susceptible whereas stone dust added<br />

at 1% is less temperature susceptible.<br />

• From Pen – Vis Number (PVN), for unaged VG<br />

20 grade bitumen, lime added at 2% is highly<br />

temperature susceptible whereas stone dust added<br />

at 2% is less temperature susceptible. Similarly, for<br />

aged VG 20 grade bitumen, fly ash added at 2% is<br />

highly temperature susceptible whereas stone dust<br />

added at 1.5% is less temperature susceptible.<br />

ROAD RESEARCH IN INDIA 2011-12 103<br />

• From Pen – Vis Number (PVN), for unaged VG 10<br />

grade bitumen, cement added at 1.5% is highly<br />

temperature susceptible whereas lime added at<br />

2% is less temperature susceptible. Similarly, for<br />

aged VG 10 grade bitumen, lime added at 2% is<br />

highly temperature susceptible whereas stone dust<br />

added at 1% is less temperature susceptible.<br />

•<br />

•<br />

From Viscosity – Temperature Susceptibility (VTS),<br />

for unaged VG 20 grade bitumen, fly ash added at<br />

1% is highly temperature susceptible whereas stone<br />

dust added at 2% is less temperature susceptible.<br />

Similarly, for aged VG 20 grade bitumen, stone<br />

dust added at 1% is highly temperature susceptible<br />

whereas stone dust added at 2% is less temperature<br />

susceptible.<br />

From Viscosity – Temperature Susceptibility (VTS),<br />

for unaged VG 10 grade bitumen, cement added<br />

at 1% is highly temperature susceptible whereas<br />

lime added at 2% is less temperature susceptible.<br />

Similarly, for aged VG 10 grade bitumen, fly ash<br />

added at 1% is highly temperature susceptible<br />

whereas lime added at 2% is less temperature<br />

susceptible.<br />

recommendations for Dissemination/ revision of<br />

Codes/Specifications<br />

Cement added at 1% showed better resistant to aging<br />

for VG 20 grade bitumen. Similarly, for fly ash and lime<br />

added at 2 and 1.5% respectively showed better results<br />

for VG 10 grade bitumen. So in terms of aging, for VG<br />

20 grade bitumen, it is better to use cement added at<br />

1% as filler material and for VG 10 grade bitumen fly<br />

ash and lime added at 2 and 1.5% can be used as filler<br />

material.<br />

Stone dust and lime added at 2% have less temperature<br />

susceptibility for both binders at aged and unaged<br />

conditions. So in terms of temperature susceptibility, it is<br />

better to use stone dust added at 2% as filler material.<br />

Dynamic Mechanical Analysis and<br />

Development of Master Curves for Bitumen<br />

Processed in India<br />

Date of Start: July 2009<br />

Date of Completion: March 2012


104<br />

<strong>Indian</strong> Institute of Technology Madras, Chennai<br />

- 600 036<br />

Scope and Objectives<br />

•<br />

•<br />

•<br />

To conduct dynamic mechanical analysis of<br />

unmodified binders under unaged and short-term<br />

aged conditions in the temperature range of 25 to<br />

75 ºC<br />

To investigate the thermo-rheological behaviour<br />

and construct master curves under unaged and<br />

short-term aged conditions and<br />

To carry out parametric analysis of the temperature<br />

and shear susceptibility parameters of unaged and<br />

aged bitumen.<br />

Proposed Methodology<br />

The present study focused on unmodified binders<br />

under unaged and short-term aged conditions.<br />

The mechanical characterizations were carried out<br />

using small amplitude oscillatory shear tests using<br />

the Dynamic Shear Rheometer (DSR) in the linear<br />

viscoelastic regime. All the dynamic analysis was<br />

carried out over a temperature range of 25-75 o C and<br />

over a frequency range of 0.5-25.5 Hz. The master<br />

curve model proposed by Dickinson and Witt (1974)<br />

& Christensen and Anderson (1992) were used in the<br />

analysis.<br />

Salient-Findings and Conclusions<br />

•<br />

•<br />

•<br />

•<br />

•<br />

All the samples tested exhibited discontinuity in<br />

the Black diagrams in the 65-75 ºC temperature<br />

range. This was true even under short-term aged<br />

conditions. Hence, the use of time-temperature<br />

superposition for the bitumen samples tested here<br />

is valid only in the temperature range of 25-55 ºC.<br />

The cross-over frequency for all the samples<br />

decreased with the aging condition. However,<br />

one cannot say the same thing about the dynamic<br />

modulus master curve under unaged and shortterm<br />

aged conditions.<br />

Of all the master curve model parameters, the<br />

parameter β as per Dickinson and Witt (1974) and<br />

the parameter R as per Christensen and Anderson<br />

(1992) were quite sensitive to the variability of the<br />

binders tested.<br />

Based on the analysis of β and R, the air blown<br />

samples exhibited better temperature and shear<br />

susceptibility when compared to blended samples<br />

for a given aging conditions.<br />

Aging changes the temperature susceptibility of<br />

the material and such changes are captured by the<br />

master curve model parameters, especially β and<br />

R.<br />

GENERAl REPORT ON<br />

• When compared<br />

with the performance grade<br />

database for all the bitumen samples tested,<br />

samples exhibiting good temperature and shear<br />

susceptibility exhibited a wider performance grade<br />

temperature range.<br />

•<br />

Analysis of the 100 sample database for their<br />

penetration at 25 ºC and viscosity at 60 ºC revealed<br />

that samples having good temperature and shear<br />

susceptibility always had higher penetration for<br />

a given viscosity range. For instance, samples<br />

having R value of 0.9 and above, shows a higher<br />

penetration value of 60 within a viscosity range of<br />

1600-2400.<br />

8 months<br />

Date of Completion: 16.08.2012<br />

<strong>Indian</strong> Institute of Technology Madras, Chennai<br />

- 600 036<br />

Scope and Objectives<br />

1. To characterize the non–Newtonian to Newtonian<br />

transition of asphalt<br />

2. To characterize the viscoelastic fluid to viscoelastic<br />

region of 20 to 160 ºC to identify the transition of asphalt.<br />

Dynamic shear rheometer was used in the temperature<br />

region of 20 to 90 ºC and rotational viscometer was<br />

used in the temperature region of 90 to 160 ºC<br />

Salient-Findings and Conclusions<br />

•<br />

•<br />

Asphalt exhibited non-Newtonian to Newtonian<br />

transition in 100 to 140 ºC<br />

Viscoelastic solid-like to viscoelastic fluid-like<br />

transition occurred in 20 to 50 ºC temperature<br />

region.


• These transition temperature depends on<br />

processing method and aging condition of asphalt.<br />

•<br />

Transition was shifted to higher side on aging<br />

Performance of Stone Matrix Asphalt using<br />

Crumb Rubber Modified Bitumen and Modified<br />

Aggregates<br />

Date of Start and Duration: June 2011, 10<br />

months<br />

Date of Completion: March 2012<br />

National Institute of Technology Karnataka,<br />

Surathkal<br />

Scope and Objectives<br />

The scope of the present work involves the determination<br />

of various physical properties of the bitumen and<br />

aggregates used for SMA Mix. SMA samples are<br />

prepared by varying the binder content in Marshall<br />

Method and Superpave Gyratory Compactor (SGC).<br />

These specimens are analyzed for the density-voids<br />

and stability-flow. The optimum bitumen content for the<br />

mix with CRMB-55 and Terrasil treated aggregates are<br />

determined. The laboratory performances of the SMA<br />

mixes are checked for moisture susceptibility, rutting<br />

and repeated load tests. Drainage test was conducted<br />

to check for the binder drainage. Permeability tests<br />

were conducted to study permeable nature of SMA<br />

mixes with CRMB-55 and treated aggregates. Moisture<br />

susceptibility tests include the evaluation of Indirect<br />

Tensile Strength, Tensile Strength Ratio and boiling test<br />

for stripping. The rutting studies include determination<br />

of rutting depth by using Immersion Wheel Tracking<br />

Device (IWTD). Repeated load tests were carried out on<br />

SMA samples with CRMB-55 and treated aggregates<br />

to determine its fatigue life.<br />

Objectives:<br />

Disposal of waste tires is a serious environmental<br />

concern in many countries. In order to solve this<br />

environmental problem partly and at the same time to<br />

improve the performance of Stone Matrix Asphalt (SMA),<br />

CRMB-55 was used for the investigation. Another<br />

attempt of SMA Mix using an anti-stripping additive<br />

was done. The objective of the present investigation is<br />

given below:<br />

1.<br />

To reduce anti-stripping by treating aggregates<br />

using anti-stripping agents.<br />

GENERAl REPORT ON<br />

2. To study<br />

the characteristics of SMA mixes using<br />

CRMB-55 binders and a mix using treated<br />

aggregates and VG-30.<br />

3.<br />

4.<br />

5.<br />

To evaluate the stability, flow value and volumetric<br />

properties of SMA mixes with CRMB-55 and<br />

treated aggregates by using Marshall Method and<br />

Superpave Gyratory Compactor.<br />

To study the indirect tensile strength, permeability,<br />

rut depth and amount of stripping of SMA mixes<br />

with CRMB-55 and treated aggregates.<br />

To study the performance of SMA mixes with<br />

CRMB-55 and treated aggregates under repeated<br />

loads.<br />

Proposed Methodology<br />

Experimental studies were conducted in laboratory as<br />

mentioned in the Scope.<br />

Salient-Findings and Conclusions<br />

On the basis of analysis of results obtained in the<br />

present investigation, the following conclusions can be<br />

made:<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

The results obtained from Marshall and SGC<br />

method provides similar results. Marginal difference<br />

in density values were observed for SMA samples<br />

prepared by SGC method because of its compactive<br />

effort.<br />

Addition of CRMB-55and modified aggregates<br />

improves the volumetric properties of SMA. The<br />

OBCof the SMA mixes with CRMB-55 and modified<br />

aggregates were 6.2% and 6% using Marshall<br />

and SGC respectively. From the results, it is clear<br />

that there is not much difference in the volumetric<br />

properties of SMA prepared using Marshall and 80<br />

gyrations in SGC.<br />

The SMA mixes were found to be having good<br />

stone-on-stone contact. Addition of CRMB-55 and<br />

modified aggregates decreased the draindown<br />

value and hence the stabilizer additives can be<br />

avoided.<br />

The boiling test proved that there is no stripping in<br />

the SMA mixprepared using modified aggregates<br />

and 10% stripping in the mix with CRMB-55.<br />

TSR was found to be more than 80% for all the SMA<br />

mixes used in the study. Higher TSR is obtained for<br />

SMA mix using modified aggregates which indicate<br />

better cohesive strength of this mix as compared to<br />

SMA mix using CRMB-55.<br />

Test results indicate that the SMA specimen<br />

using CRMB-55 is less susceptible to permanent


•<br />

deformation (rutting) than that with modified<br />

aggregates.<br />

Repeated load test results prove that the fatigue<br />

life of SMA specimen using CRMB-55 was higher<br />

as compared to the fatigue life of SMA specimen<br />

using modified aggregates.<br />

Proposed Methodology<br />

Experimental studies were conducted in laboratory as<br />

mentioned in the Scope.<br />

Salient-Findings and Conclusions<br />

On the basis of analysis of results obtained in the<br />

present investigation, the following conclusions are<br />

drawn:<br />

Marshall Stability<br />

•<br />

Addition of PMB improves the volumetric properties<br />

of SMA.The OBC at 4% air voids was found<br />

to be 6.4% and 6.3% for PMB 70 and PMB 40<br />

respectively. The Marshall Stability value at OBC<br />

for SMA mix prepared with PMB 70 was found to<br />

be 3.05% more than that of SMA mix prepared with<br />

PMB 40.<br />

Superpave Gyratory<br />

•<br />

•<br />

•<br />

•<br />

The OBC at 4% air voids was found to be 6.3% and<br />

6.32% for PMB 70 and PMB 40 respectively. The<br />

SGC Stability value at OBC for SMA mix prepared<br />

with PMB 40 was found to be 5.44% more than that<br />

of SMA mix prepared with PMB 70.<br />

PMB 40 and PMB 70 binder showed very negligible<br />

draindown values. This indicates that separation<br />

of fines and bitumen noticed during transportation<br />

and placing of the mixture is restricted to a large<br />

extent.<br />

The Tensile Strength Ratio was found to be more<br />

than 85%. This shows that addition of PMB increases<br />

the moisture resistivity of the SMA Mix, which is<br />

due to the coating of PMB to the aggregates.<br />

SMA mix modified with PMB was resistant to<br />

stripping even when subjected to worst moisture<br />

conditions.


108<br />

•<br />

•<br />

•<br />

SMA mix modified with PMB showed that the mixes<br />

are impermeable.<br />

PMB modified SMA mixes are less susceptible to<br />

permanent deformation (rutting), as the deformation<br />

obtained was less than 2mm. Use of PMB 70<br />

reduced the total depression depth by 46% less to<br />

that of the mix prepared with PMB 40.<br />

Fatigue life of SMA mix prepared with PMB 40 was<br />

5.19% greater than that of SMA mix prepared with<br />

PMB 70.<br />

2)<br />

3)<br />

4)<br />

5)<br />

To investigate the performance of BC mixes with<br />

treated aggregate compacted by Superpave<br />

Gyratory compactor and Marshall Compactor.<br />

To know the effects on stripping properties on<br />

aggregates after treating aggregate with chemical.<br />

To study the moisture susceptibility characteristics<br />

The scope of the present work involves:<br />

Marshall test: Marshall and Superpave Gyratory<br />

Compactor Specimens were prepared by varying the<br />

binder content, with and without stabilizer and the<br />

Properties such as Stability, flow, unit weight and air<br />

void content of the Bituminous Concrete mixes have<br />

been studied. Optimum Binder Content (OBC) was<br />

GENERAl REPORT ON<br />

found out from these parameters and the next sets of<br />

experiments were carried out on mixes prepared at<br />

OBC.<br />

Moisture susceptibility tests: The loss of adhesion<br />

of bitumen from aggregates has been studied using<br />

retained stability test, boiling test and tensile strength<br />

ratio test. The test results show that the BC mixes with<br />

treated aggregates have better resistance to moisture<br />

damage than the mixes with untreated aggregates.<br />

permanent deformation: Permanent deformation<br />

or rutting potential of mixes has been studies using<br />

Immersion Wheel Tracking Device (IWTD). The test<br />

results show that the BC mixes with treated aggregates<br />

have better resistance to rutting damage than the mixes<br />

with untreated aggregates.<br />

Repeated load test: The repeated load indirect<br />

tensile test has been adopted to study the fatigue life<br />

characteristics of BC mixes. Repeated load tests have<br />

been conducted at three different load levels. The<br />

resilient modulus of elasticity, resilient Poisson’s ratio,<br />

tensile stress, tensile strain etc. has been computed. It<br />

has been observed from the test results that, BC mixes<br />

with treated aggregate offer highest resilient modulus<br />

and fatigue life.<br />

Proposed Methodology (Type of Study, Laboratory/<br />

Field)<br />

Experimental studies were conducted in laboratory as<br />

mentioned in the Scope.<br />

Salient-Findings and Conclusions:<br />

Based on the results and discussions of experimental<br />

investigations carried out on Bituminous Concrete<br />

mixes the following conclusions are drawn:<br />

•<br />

•<br />

•<br />

•<br />

The results obtained from Marshall and SGC<br />

method provides similar results. Marginal difference<br />

in density and stability values were observed for<br />

Bituminous Concrete samples prepared by SGC<br />

method.<br />

The boiling test proved that there is no stripping in<br />

the mix prepared by treated aggregates.<br />

The percentage retained stability obtained is<br />

increased by 11 per cent for the mixes with treated<br />

aggregate as compare to mixes with untreated<br />

aggregate.<br />

When compared to the untreated mixes the ITS<br />

values for unconditioned and conditioned samples<br />

with treated aggregates increased by 6 %, 22 %<br />

respectively.<br />

TSR was found to be<br />

• more than 80% for all the<br />

BC mixes. Higher TSR values are obtained for


•<br />

•<br />

•<br />

mixes using treated aggregates which indicate<br />

better cohesive strength of this mix as compared<br />

to normal mix. This shows that mixes with treated<br />

aggregate are not susceptible to moisture.<br />

Test results indicate that the bituminous mixes with<br />

treated aggregates are less susceptible to rutting<br />

than normal bituminous concrete mixes. It was<br />

observed that total depression depth with mixes<br />

with treated aggregate has reduced by 42% as<br />

compared to normal mixes.<br />

Based on the skid resistance test conducted after<br />

10000 wheel passes it was found that the surface<br />

with treated aggregates has slightly higher skid<br />

resistance value (72) than conventional mix (62).<br />

It was observed that the fatigue life (number of<br />

cycles) for mixes with and without treated aggregate<br />

were 2312 and 2263 respectively. Therefore the<br />

fatigue life of treated aggregate is marginally higher<br />

than the normal mix.<br />

Laboratory Investigation of Warm Mix Asphalt<br />

Using Chemicals and Comparision with Hot<br />

Mix Asphalt (Bituminous Concrete)<br />

Date of Start and Duration: June 2011, 10<br />

months<br />

Date of Completion: March 2012<br />

National Institute of Technology Karnataka,<br />

Surathkal<br />

Scope and Objectives<br />

This study mainly deals about the properties of<br />

bituminous concrete (BC) mix produced using Zydex<br />

Warm Mix Technology and to compare them with that<br />

of HMA.<br />

1.<br />

2.<br />

To compare the properties of WMA to that of HMA<br />

for the BC grade specified by MoRT&H.<br />

To know whether the WMA produced by Zydex<br />

Warm Mix technology meets the requirements and<br />

will it be used as the alternative for HMA.<br />

The primary objective of this research is to find out<br />

whether warm mix asphalt is a viable option for the<br />

paving industry in India. In the process of answering<br />

ROAD RESEARCH IN INDIA 2011-12 109<br />

that question, WMA’s advantages and disadvantages<br />

compared to traditional HMA are explored and the<br />

question of whether WMA is a viable paving option for<br />

cold weather conditions in general is also answered.<br />

The conclusions of this work are primarily drawn from a<br />

literature review that was conducted on warm mix asphalt<br />

to evaluate what is known about its performance.<br />

The Zydex Warm Mix Technology is evaluated using<br />

multiple laboratory tests to determine the effect of this<br />

additive on mixture rutting resistance and moisture<br />

damage resistance. This verification was also used to<br />

determine if the addition of the Zycosoil and Densicryl<br />

had any tangible effect on the compaction of the<br />

mixture. The WMA samples were then tested for Tensile<br />

Strength Ratio (TSR) and Immersion Wheel-Tracking<br />

Tests (IWT) and are compared with that of HMA. The<br />

TSR and IWT can be used to determine a mixture’s<br />

laboratory moisture susceptibility and resistance to<br />

rutting respectively.<br />

Proposed Methodology<br />

Experimental studies were conducted in laboratory as<br />

mentioned above.<br />

Salient-Findings and Conclusions<br />

On the basis of analysis of results obtained in the<br />

present investigation, the following conclusions are<br />

drawn<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

The OBC at 4% air voids was found to be 5.5%<br />

and 5.33% for HMA and WMA respectively as<br />

the addition of chemicals reduces the viscosity of<br />

the binder. Thus making the binder to cover the<br />

aggregates easily. The Marshall Stability value at<br />

OBC for WMA was found to be 9.3% more than<br />

that of HMA.<br />

WMA binder treated with Zycosoil and Densicryl<br />

showed very negligible draindown values. This<br />

indicates that separation of fines and bitumen<br />

noticed during transportation and placing of the<br />

mixture is restricted to a large extent.<br />

The Tensile Strength Ratio was found to be more<br />

than 85% for WMA. This shows that WMA exhibits<br />

better resistance to moisture susceptibility, which is<br />

due to the coating of binder to the aggregates.<br />

WMA mix is highly resistant to stripping even when<br />

subjected to worst moisture conditions.<br />

WMA mixes are impermeable.<br />

WMA mix exhibits lower rutting property compared<br />

to HMA because of the reduced oxidation.<br />

WMA shows slightly better resistance against<br />

fatigue when compared to HMA.

Cost Comparison of WMa and HMa<br />

The use of chemicals in the preparation of WMA resulted<br />

in improved workability that can ensure a higher quality<br />

in road construction. This ensures that a higher level of<br />

compaction can be achieved with fewer roller-passes.<br />

Thus by reducing the operation cost also. The cost of<br />

HMA of BC Grade-1 per m 3 as per latest Schedule of<br />

Rates (SOR) of Public Welfare Department, Karnataka<br />

state is RS 8724.00 /m 3 and the cost of WMA produced<br />

by Zydex Technology is Rs 8479.00. The rates indicate<br />

a large amount of difference in the costs. The WMA<br />

reduces the construction cost by 2.8% when compared<br />

to HMA.<br />

Scope and Objectives<br />

The scope of study will be confined to selected cities<br />

in Kerala State. A case study of Trivandrum and Kochi<br />

Urban Area will be selected to analyse the variations<br />

in the forecasts made. The objectives of the study are<br />

given below:<br />

To undertake an analysis of socio-economic<br />

variables, travel behaviour and traffic flow pattern<br />

that has influence on demand forecasting;<br />

To evaluate the accuracy of selected variables<br />

by comparing the study forecasts with the actual/<br />

observed data in the selected city;<br />

iii) To critically examine the assumptions made<br />

in forecasts and the cause-effect in predictive<br />

accuracy of these variables;<br />

GENERAl REPORT ON<br />

iv) To prepare general guidelines for realistic<br />

assumption and forecasting of input variables in<br />

such studies.<br />

Proposed Methodology<br />

National Transportation Planning and <strong>Research</strong> Centre<br />

(NATPAC) has undertaken Traffic and Transport<br />

studies for a number of towns in Kerala during the last<br />

30 years. This includes five City Corporations namely:<br />

Thiruvananthapuram, Kollam, Cochin, Thrissur and<br />

Kozhikode and over 30 small and medium size towns<br />

in the state. Available data from these studies will be<br />

utilised to assess the accuracy of various parameters by<br />

comparing the study forecasts with the actual changes<br />

that have taken place. An evaluation of variations in<br />

planning variables like population growth, employment,<br />

land use, vehicle ownership, traffic volume etc will be<br />

undertaken. The assumptions made in the study will also<br />

be critically examined and suitable recommendations<br />

will be made. Based on the evaluation of predictive<br />

accuracy of selected parameters, a general guide line<br />

will be prepared for future use.<br />

Salient Findings and Conclusions<br />

Sample data from 19 transport studies of Trivandrum<br />

and Kochi city, undertaken between 1981 and 2011,<br />

were used to evaluate their predictive accuracy.The<br />

comparison of demographic and socio-economic<br />

forecasts shows a trend of overestimation while the<br />

comparison of traffic characteristics indicates a lack<br />

of incorporation of fundamental shifts and societal<br />

changes. On an average, land use input variables<br />

(population and employment) of both cities were<br />

overestimated by 1 to 24 per cent for a forecasting<br />

period of 10 years. Almost all forecasts for land use<br />

types were overestimated by an average of <strong>39</strong> per<br />

cent in case of Trivandrum city where for Kochi city<br />

the forecasts were underestimated by an average of<br />

17 percent. Traffic parameters like expected vehicle<br />

population and traffic flow on corridors were heavily<br />

under estimated for both cities by 13 to 94 per cent.<br />

The average income for the horizon year was not<br />

foreseen and accounted for during the modeling<br />

process. Thus an important variable like per-capita<br />

income was not for forecasted for the horizon year<br />

and the base year value taken which further led to<br />

irregularities in predicting the vehicle ownership levels<br />

and the total vehicle population of the city.This increase<br />

in the vehicle population led to an increase in the number<br />

of trips. Therefore, there occurred a flaw in the traffic<br />

flow assignment on the road network. Parameters like<br />

land use and vehicle population were borrowed from<br />

various governmental departments instead of being<br />

forecasted by the transport planners. The development<br />

of the city and improvement in the economy was not<br />

considered during the planning. This combined with the<br />

rapid motorization that took place in Kerala during the


last two decades, resulted in large number of trips that<br />

was not accounted for during trip assignments.<br />

Further analysis of the data showed that an assumption<br />

of zero variation from base year situation had mixed<br />

response. Such an assumption would have produced<br />

smaller errors for socio-economic variables like<br />

population, employment in case of Trivandrum City and<br />

larger errors in case of Kochi City. Assumption of zero<br />

variation would have produced larger errors for traffic<br />

parameters. However, when the studies were ranked<br />

according to their forecast percentage variations<br />

and observed percentage variations, the rankings by<br />

population and daily traffic volume were found to be<br />

positively correlated. This implied that for these, but<br />

not for other items, transport planners as a whole<br />

were successful in predicting whether the variations or<br />

changes applicable to their own specific areas would<br />

be greater or less than average, but as a group they<br />

tended to overestimate these changes.<br />

Although the results were necessarily based on studies<br />

that started between 1981 and 2000, to allow sufficient<br />

time to have elapsed to test their predictive accuracy,<br />

many of the modeling methods used in those studies<br />

is still in use. However, no evidence could be found<br />

to suggest that the more recent studies or the more<br />

sophisticated of the studies investigated performed<br />

better than the others.<br />

The overriding factor affecting the accuracy of trip<br />

forecasts was over prediction of the growth in variables<br />

such as population, employment and under prediction<br />

of travel costs, household income and economic<br />

growth. So the errors of prediction outweighed the<br />

errors of measurement and model specification. There<br />

was also evidence that transport models used in the<br />

studies contained errors of specification, particularly<br />

in their forecasting of vehicle population and traffic<br />

volume. The possible effect of specification errors was<br />

obscured by the dominating effect of the errors in the<br />

planning input variables.<br />

Measurement of Dynamic Modulus using<br />

Asphalt Mixture Performance Tester (AMPT)<br />

Date of Start and Duration: 02-07-2011, 1 year<br />

Date of Completion: 11-05-2012<br />

<strong>Indian</strong> Institute of Technology Madras, Chennai<br />

- 600 036<br />

ROAD RESEARCH IN INDIA 2011-12 111<br />

Scope and Objectives<br />

Dynamic modulus testing was done on bituminous<br />

concrete mixture (BC G2) using unmodified VG 30<br />

binder. The test was done for six different frequencies<br />

(0.01, 0.1, 1, 5, 10, 25 Hz) at six test temperatures<br />

(5, 15, 25, 35, 45, 55 °C). The tests were done by<br />

conducting amplitude sweeps using AMPT.<br />

Objectives:<br />

1.<br />

2.<br />

3.<br />

4.<br />

To check the efficacy of dynamic modulus testing<br />

procedure provided within AMPT<br />

To evaluate the influence of data quality statistics<br />

on dynamic modulus measurement<br />

To determine the linear viscoelastic (lVE) regime<br />

for dynamic modulus measurement<br />

To construct lissajous Plots for asphalt concrete<br />

mixture<br />

Proposed Methodology<br />

Experimental Studies (Amplitude Sweep Tests) were<br />

conducted using AMPT at different temperatures for<br />

different frequencies. Seven test specimens were used<br />

each having target air voids of 4% with a tolerance of<br />

±0.5 % and 5 % binder content. The specimens were<br />

cylindrical in shape of 165 mm height and 150 mm<br />

diameter. Dynamic Modulus was calculated using two<br />

existing protocols (AASHTO TP: 62 – 07 & AASHTO<br />

TP: 79 – 10) based on a linear summation model. The<br />

maximum amplitudes of stresses and corresponding<br />

strains were obtained using curve fitting of sinusoidal<br />

functions and then dynamic modulus was obtained as<br />

the ratio of maximum stress amplitude to maximum<br />

strain amplitude.<br />

Salient-Findings and Conclusions<br />

Dynamic Modulus is a linear viscoelastic parameter.<br />

Hence when measurement becomes nonlinear, the<br />

dynamic modulus starts depending on applied loads<br />

as well as corresponding strains. linear viscoelastic<br />

regime was determined for asphalt concrete mixture<br />

using AMPT to determine dynamic modulus. The study<br />

was conducted at different temperatures for different<br />

frequencies since dynamic modulus is a function of<br />

temperature and frequency.<br />

Conclusions:<br />

•<br />

•<br />

lVE Regime of asphalt concrete mixtures can be<br />

obtained by conducting stress amplitude sweep<br />

tests on cylindrical specimens using AMPT<br />

The results obtained from study shows that for<br />

asphalt concrete mixtures, the measurement<br />

of dynamic modulus with the existing protocol


112<br />

•<br />

•<br />

(AASHTO TP:79–10) is done within linear<br />

viscoelastic regime for very high temperatures like<br />

55 °C and very low temperatures like 5 ° C<br />

The nonlinear measurement of dynamic modulus<br />

is seen at intermediate temperatures like 15, 25<br />

and 35 ° C. For 15 and 45 ° C, the measurement<br />

of dynamic modulus becomes nonlinear at lower<br />

frequencies<br />

The data quality statistics (dqs) have greater<br />

influence on the measurement of dynamic modulus.<br />

The measured dynamic modulus will not be correct<br />

if the value of data quality statistics obtained is<br />

above the permissible limits<br />

modulus.<br />

The methodology can also be extended to the case<br />

of pavements designed for a specified Factor of<br />

Safety (FOS), wherein the Bayesian back-analysis<br />

Reliability<br />

Models<br />

Analysis of Pavement Rutting<br />

<strong>Indian</strong> Institute of Science, Bangalore<br />

Scope and Objectives<br />

The scope of the study includes an analysis of the<br />

rutting models used in design of asphalt pavements<br />

by mechanistic-empirical method, based on reliability<br />

theory. The objectives can be stated as follows<br />

•<br />

•<br />

To address the need for reliability analysis in<br />

pavement design and to review the rutting models<br />

developed for design of asphalt pavements by<br />

mechanistic-empirical method, at the different<br />

levels of specified reliability.<br />

To consider the effects of the inherent variability of<br />

the input parameters on the pavement performance<br />

and to evaluate the consequence of choosing<br />

different reliability level on the design.<br />

Proposed Methodology<br />

The methodology proposed for the reliability analysis of<br />

the rutting models is a numerical simulation technique


ased on reliability analysis methods including the<br />

First Order Reliability Method (FORM) and load and<br />

Resistance Factor Design (lRFD).<br />

Salient Findings and Conclusions<br />

The findings from the study are as follows:<br />

•<br />

•<br />

The effect of the variability of the design parameters<br />

on the pavement performance was studied through<br />

reliability analysis and it was found that variability<br />

of the thickness of the surface and base layers,<br />

and the subgrade modulus has a significant impact<br />

on the design reliability of pavements.<br />

In pavement design, the application of reliability<br />

methods in pavement design is underutilized,<br />

particularly in codes and design guides that depend<br />

heavily on empirical data and the criterion for<br />

selecting the reliability level is primarily governed<br />

by the importance of the road section. This study<br />

shows the importance of incorporating parametric<br />

uncertainty in the determination of pavement<br />

reliability through the estimation of partial factors,<br />

the drawbacks of assigning such reliability levels<br />

without the explicit consideration of the design<br />

uncertainties is highlighted.<br />

Application of Study on Structural<br />

Characteristics of Bituminous Mix with Added<br />

Fibres<br />

Date of Start: August 2011.<br />

Date of Completion: August 2012.<br />

College of Engineering, Trivandrum (R)<br />

Scope and Objectives<br />

Flexible pavements are the most common pavement<br />

structure. The surface course of the structure is<br />

bituminous mixture, i.e. a mixture of graded aggregates<br />

(either well graded or gap graded) and bitumen<br />

(asphalt cement). Asphalt pavements are a crucial part<br />

of our nation’s strategy for building a high performance<br />

transportation network for the future. Asphalt construction<br />

ROAD RESEARCH IN INDIA 2011-12 113<br />

is fast and relatively simple; it is economical, and the<br />

materials to make it are widely available .Attempts are<br />

constantly made to improve these pavement through<br />

several programmes. As a result of these programmes,<br />

asphalt binder specifications and asphalt concrete<br />

mixture design methods have been completely revised<br />

and combined in a new system known as Superpave,<br />

which stands for superior performing pavements.<br />

Extensive research continues in an attempt to optimize<br />

the superpave system and construct better performing,<br />

long lasting pavements.<br />

Flexible pavements are prone to various distresses such<br />

as ravelling, fatigue crack etc one of the most common<br />

method to reduce these distresses is to reinforce the<br />

bituminous mix. Commonly fibers are used to reinforce<br />

the bituminous mix. Synthetic as well as natural fibers<br />

could be used for reinforcement. Studies on stability,<br />

flow and volumetric properties of FRBC revealed that<br />

by adding fibers showed varied result which is as<br />

follows. Generally, Stability increases because addition<br />

resistance provided by the fibers. Flow decreases<br />

because flow (deformation) was resisted by fibers. Air<br />

voids increases because fibers absorb binder needed<br />

to coat the aggregate there by introduces a air gap<br />

between aggregates.<br />

Present study is to investigate the effect of using fibers<br />

such as Recron fiber, Coir fiber and Polypropylene fiber<br />

on the Structural, Creep, Surface Characteristics of the<br />

bituminous mix.<br />

The objectives of this study are:<br />

•<br />

•<br />

•<br />

•<br />

To develop a mix design for bituminous mix with<br />

added Recron fiber, Coir fiber, and Polypropylene<br />

fiber<br />

To study the creep characteristics of the bituminous<br />

mix with added Recron fiber, Coir fiber and<br />

Polypropylene fiber<br />

To study the skid resistance of the mix with added<br />

Recron fiber, Coir fiber and Polypropylene fiber<br />

To make a comparative study of the results obtained<br />

before and after the addition of Recron fiber, Coir<br />

fiber and Polypropylene fiber<br />

The scope of the work is limited to laboratory<br />

investigations in the bituminous mix with added Recron<br />

fiber, Coir fiber and Polypropylene fiber. The study is<br />

also limited to stress strain characteristic and surface<br />

characteristics of bituminous concrete mix.<br />

•<br />

Stiffness modulus and surface characteristics of<br />

bituminous mixes can be enhanced by adding<br />

that of control mix<br />

As the mix become stiffer the vertical strain are<br />

reduced hence the deflections at various points<br />

are reduced and the stiffness of the mix increases<br />

when the creep strain decreases<br />

Life-Cycle Cost Analysis of Long Lasting<br />

Pavements<br />

<strong>Indian</strong> Institute of Science, Bangalore<br />

Scope and Objectives<br />

The study explores the feasibility of designing longlasting<br />

pavements based on the theory of limiting<br />

structural responses and the economic advantages<br />

of such long-lasting designs was evaluated through a<br />

life Cycle Cost Analysis (lCCA). The objectives of the<br />

study are<br />

•<br />

•<br />

To highlight the effect of increasing the thickness of<br />

the Hot Mix Asphalt (HMA) over the granular layer on<br />

the critical pavement responses and overall design<br />

thickness, by designing pavements according to<br />

the philosophy followed in IRC:37(2012).<br />

To examine the effect of providing stiffer base<br />

materials on the pavement design for conventional


•<br />

pavements (15 years) and long-lasting<br />

pavements.<br />

To design long-lasting pavements and to perform<br />

lCCA for all the design alternatives to highlight<br />

the economic advantages of providing perpetual<br />

pavements over an equivalent conventional<br />

pavement designed according to IRC:37(2012),<br />

over a period of 50 years.<br />

Proposed Methodology<br />

The methodology proposed for the design of long<br />

lasting Pavements employs the concepts of perpetual<br />

pavements, wherein the critical pavement responses<br />

are computed using the pavement analysis software,<br />

KENPAVE and the economic feasibility of the design<br />

is evaluated through a life-cycle cost analysis, using<br />

lCCA Express.<br />

Salient Findings and Conclusions<br />

The study shows that although the concept of perpetual<br />

pavements advocates the increase of HMA thickness<br />

to keep the critical strains within the threshold limits,<br />

the provision of a stable foundation and the high<br />

stiffness base materials are equally significant from<br />

a financial perspective. This can be attributed to the<br />

increasing cost of asphalt in India, with the rising price<br />

of crude oil. Thus, the implementation of long-lasting<br />

pavements in India calls for development in the area of<br />

soil stabilization or the provision of treated subgrade,<br />

and the use of high stiffness base materials.<br />

parameters on the reliability index through a sensitivity/<br />

elasticity analysis. The effect of changing Coefficient Of<br />

Variation (COV) in pavement parameters and varying<br />

traffic load on the Partial Safety Factors were also<br />

analysed.<br />

Proposed Methodology<br />

The probabilistic analysis of the pavement within the<br />

Mechanistic-Empirical framework was carried out<br />

based on the First Order Reliability Method (FORM),<br />

using the software STRUREl which is capable of<br />

determining both component and system reliability.<br />

Salient Findings and Conclusions<br />

The following conclusions were drawn from the study<br />

1)<br />

2)<br />

From the perspective of design reliability, the most<br />

critical parameter was identified as the surface layer<br />

thickness as evaluated from the sensitivity/elasticity<br />

values. The determination of the most significant<br />

parameter is useful in attaining the designs with<br />

a target reliability level or the specified reliability<br />

range since higher levels of reliability can be<br />

achieved with small variations in this parameter.<br />

The study shows that while the Partial Safety Factors<br />

are influenced considerably by the uncertainties in<br />

material properties such as layer thickness and<br />

layer moduli, the variations in the traffic load have<br />

a minimal impact on these factors.<br />

Scope and Objectives<br />

The objective of present study is to design flexible<br />

pavements using finite element method of analysis.


116<br />

The following different pavements subjected to different<br />

conditions have been analyzed effectively using the<br />

available software packages KENPAVE (for flexible<br />

pavements).<br />

The main objective of this research is to improve the<br />

locally available lateritic soil. Due to high silt and clay<br />

content, the soil is blended with sand and quarry dust to<br />

improve its engineering properties (ll≤25%, PI≤ 6%).<br />

The soil is further strengthened by placing a coir mat<br />

geotextile. load-settlement behavior is analysed by<br />

conducting plate load tests. An FEM software package<br />

‘KENPAVE’ is used to study the vertical stress, vertical<br />

displacements and radial stress with respect to different<br />

radial coordinates. The strengthened soil is used as a<br />

modified soil layer above the sub-grade so as to obtain<br />

the modified thickness of pavement as given by IRC<br />

The soil blended with 50% sand and coir mat<br />

can be a substitute for the modified soil and GSB<br />

(Granular Sub Base).<br />

The vertical stress at the interface of modified soil<br />

for S1T3 is 28.09KPa, whereas for conventional<br />

pavement it is 29.21KPa.<br />

By introducing of modified soil layer above the sub<br />

grade, the pavement section thickness is reduced<br />

by 75mm for S1T3 and similar trend is observed for<br />

other combinations of traffic.<br />

The analysis indicates that as the number of axles<br />

increases the stress at interface of all the layers<br />

decreases. Maximum stress values are observed<br />

when a single axle single wheel load is applied .<br />

For pavement thickness of 475mm for S2T6<br />

the vertical stress at the interface of WBM-GSB,<br />

GSB-modified soil and modified soil-subgrade is<br />

119.6KPa, 61.89KPa and 32.<strong>39</strong>KPa respectively.<br />

Whereas for conventional pavement having<br />

thickness of 400mm when GSB is replaced by<br />

modified soil of CBR 45% the vertical stress at the<br />

interface of WBM-modified soil and modified soilsubgrade<br />

is 101.5KPa and 30.6KPa respectively.<br />

For conventional pavement having thickness of<br />

375mm when GSB is replaced by modified soil<br />

of CBR 60% the vertical stress at the interface of<br />

WBM-modified soil and modified soil- subgrade is<br />

98.32KPa and 32.13 KPa respectively.<br />

For pavement thickness of 300mm for S3T4 the<br />

vertical stress at the interface of WBM-GSB and<br />

GSB-subgrade is 220.92KPa and 83.69KPa<br />

respectively. Whereas for conventional pavement<br />

having thickness of 275mm when GSB is replaced<br />

by modified soil of CBR 45% the vertical stress at the

interface of WBM-modified soil and modified soilsubgrade<br />

is 195.4KPa and 75.47KPa respectively.<br />

For conventional pavement having thickness of<br />

275mm when GSB is replaced by modified soil<br />

of CBR 60% the vertical stress at the interface of<br />

WBM-modified soil and modified soil-subgrade is<br />

207.36KPa and 71.29 KPa respectively.<br />

When GSB layer is replaced by modified soil without<br />

changing the thickness of WBM the stresses at<br />

interface of WBM-GSB and GSB-modified soil are<br />

not within the limits. Hence the thickness of WBM<br />

has to be changed when modified soil is replaced<br />

with GSB.<br />

When GSB is replaced by modified soil and<br />

increasing the thickness of WBM the stresses are<br />

within the limits. Therefore, when modified soil is<br />

introduced as sub-base layer, then the thickness of<br />

WBM has to be enhanced(150 to 175mm and 225<br />

to 250mm)<br />

When GSB is replaced by modified soil having<br />

CBR 45 and 60% there is a considerable reduction<br />

in pavement section.<br />

Conclusion for high volume roads<br />

When modulus of elasticity of subgrade, sub-base<br />

and base course are introduced separately in the<br />

analysis for all the cases (case 2a, case 2b, case<br />

2c) there is a reduction in pavement thickness.<br />

When modulus of elasticity values of GSB are<br />

introduced according CBR values (20%, 25%,<br />

30%) the variation in thickness of pavement is<br />

negligible. Therefore by changing GSB grades<br />

(1, 2, 3, 4) the reduction in pavement thickness is<br />

marginal. Hence any grade of GSB recommended<br />

by IRC can be used.<br />

The pavement thickness has reduced when E<br />

values of subgrade, sub-base and base course are<br />

given separately.<br />

For case 1 for subgrade CBR of 2% with 10msa<br />

cumulative traffic with a pavement thickness of<br />

850mm the vertical stresses at interface of DBM-<br />

GB, GB-GSB and GSB-subgrade is 146.29KPa,<br />

56.84KPa and 13.68KPa respectively. For case<br />

2a with pavement thickness of 500mm the vertical<br />

stresses at interface of DBM-GB, GB-GSB and<br />

GSB-subgrade is 136.27KPa, 27.42KPa and<br />

13.46KPa respectively and for case 2b with<br />

pavement thickness of 500mm the vertical stresses<br />

at interface of DBM-GB, GB-GSB and GSBsubgrade<br />

is 1<strong>39</strong>.47KPa, 29.52KPa and 13.23KPa<br />

respectively. For case 2c with pavement thickness<br />

of 500mm the vertical stresses at interface of DBM-<br />

GB, GB-GSB and GSB-subgrade is 142.<strong>39</strong>KPa,<br />

31.44KPa and 13.02KPa respectively. From the<br />

ROAD RESEARCH IN INDIA 2011-12 117<br />

above results it is concluded that if the material<br />

properties (E values) are given independently there<br />

is reduction in pavement thickness.<br />

Experimental Investigation of the Influence<br />

of Coir Geotextiles on Adherence Property of<br />

Bituminous Mixes<br />

Date of Start: January 2011.<br />

Date of Completion: August 2012.<br />

College of Engineering, Trivandrum (R)<br />

Scope and Objectives<br />

The scope of the work is limited to laboratory<br />

investigations by using five types of coir geotextiles<br />

collected from Charankattu Coir Mfg. co. (P). lTD,<br />

Cherthala. The coir geotextiles are cheap and easily<br />

available. The study was limited to finding the adherence<br />

stress between the bituminous concrete mix and coir<br />

geotextiles. The other limitation of this study was that<br />

the effect of variation in temperature, even though an<br />

important factor, was not considered in this study. This<br />

is because all the adherence tests were carried out at<br />

room temperature due to the absence of temperature<br />

controlled cabinet.<br />

The objectives of this study are:<br />

•<br />

•<br />

•<br />

•<br />

To determine the optimum tack coat content for<br />

obtaining the highest adherence stress<br />

To determine the maximum improvement in ultimate<br />

load of a pavement section when using different<br />

types of coir geotextiles<br />

To determine the type of coir geotextile which<br />

gives maximum adherence stress for a particular<br />

displacement<br />

To Model the behavior of pavement structure with<br />

Coir geotextiles as intermediate layer between<br />

existing pavement layer and new overlay using<br />

Regression Model Analysis.<br />

Methodology<br />

For conducting the test, specimens were prepared with<br />

three layers of bituminous mix with two inter layers of


118<br />

coir geotextiles and tack coat content between them.<br />

In this case, a new procedure was used to find the<br />

adherence stress between bituminous mixes and coir<br />

geotextiles. This configuration does not correspond to<br />

the one used in roads. <strong>No</strong> special testing equipment<br />

was required for this test and only a static press is<br />

needed for the testing of samples using UTM. The<br />

Methodology includes<br />

(a)<br />

Selection of mix materials and coir geotextiles.<br />

(b) Determining the properties of coir geotextiles and<br />

mix materials.<br />

(c) Preparation of test specimens with and without coir<br />

geotextiles (control specimen).<br />

(d)<br />

Conducting laboratory experiments.<br />

(e) A comparative study is done by using the results<br />

obtained with and without coir geotextile interface.<br />

(f)<br />

Results were analyzed and modeling is done to<br />

determine interaction between coir geotextiles and<br />

overlay using SPSS software.<br />

Findings/Conclusions<br />

Following conclusions were drawn from the study:<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

Adherence stress between pavement layers was<br />

improved significantly with the coir geotextiles.<br />

The coir geotextiles helps to reduce the displacement<br />

of overlays compared to control specimen.<br />

The optimum tack coat content for obtaining<br />

the highest adherence stress for all types of coir<br />

geotextiles was 0.9Kg/m2 CCM 700 type coir geotextiles showed maximum<br />

improvement in load carrying capacity over control<br />

specimen.<br />

Among the five varieties of coir geotextiles used,<br />

CCM 400 was found to be the best choice for a<br />

particular displacement.<br />

The maximum improvement in adherence stress<br />

was 8.7 times and the minimum improvement<br />

was 3.15 times, control specimen value for a<br />

displacement ratio of 0.02.<br />

Mix Design of Pervious Concrete – An<br />

Experimental Study Using Crushed Stone and<br />

River Sand as Fine Aggregate<br />

Date of Start and Duration: June 2011, 10<br />

months<br />

Date of Completion: March 2012<br />

National Institute of Technology Karnataka,<br />

Surathkal<br />

Scope and Objectives<br />

The main objective of this investigation is to develop a<br />

strong and durable pervious cement concrete (PCC) mix<br />

using different types of fine aggregates with varying the<br />

quantity of fine aggregates. In addition, it is also aimed<br />

to compare the properties of these PCC mixes. In the<br />

present investigation, two types of fine aggregates viz.,<br />

Crushed Stone (CS) and River Sand (RS) are used.<br />

The percentage of fine aggregates used in PCC mix is<br />

15 per cent. The properties of PCC mixes investigated<br />

are compressive strength, flexural strength, abrasion<br />

resistance, permeability and clogging potential.<br />

Proposed Methodology<br />

Experimental studies were conducted in laboratory as<br />

mentioned above.<br />

Salient Findings and Conclusions<br />

The major conclusions drawn based on the findings of<br />

the present investigation are as follows:<br />

•<br />

•<br />

•<br />

•<br />

With the increase in cement and sand content<br />

in the pervious concrete mixes, the compressive<br />

strength, flexural strength and dry unit weight are<br />

increased, where as the coefficient of permeability<br />

and the porosity get decreased.<br />

The minimum cement content for any pervious<br />

cement concrete is 230 Kg/m3. Addition of 50%<br />

more cement content resulted in a minimum of 66%<br />

increase in the compressive strength. The lowest<br />

compressive strength exhibited is 5.67 N/mm2.<br />

The flexural strengths of all the pervious concrete<br />

mixes tested were in the range from 1.83 to 3.8<br />

N/mm2. This necessitates the need for special<br />

methods for design of pervious cement concrete<br />

pavements.<br />

Highly permeable and clog-resistant pervious<br />

concrete mix is the need for the day, to serve the<br />

purpose of pavement surface drainage. All the<br />

mixes tested had permeability in the range from


•<br />

•<br />

•<br />

•<br />

•<br />

14 to 2.42 mm/s (1209 to 210 m/day). When, the<br />

same mixes were subjected to clogging, there was<br />

a reduction in the permeability by 40 to 67%. All<br />

the mixes tested, even after clogging simulation,<br />

exhibited a minimum permeability of 200 m/day.<br />

All the pervious concrete mixes tested had porosity<br />

in the range of 6.75 to 19.23%, irrespective of the<br />

method of computing porosity.<br />

The Cantabro abrasion test performed on all the<br />

pervious concrete mixes indicate that the maximum<br />

abrasion loss recorded did not exceed 19 %. This<br />

is an indication of durable pervious concrete mix.<br />

A variation in the above properties between pervious<br />

concrete mixes containing RS and CS was found<br />

to be insignificant. Curing of concrete had certainly<br />

contributed in terms of gain in strength in the range<br />

of 3.0 to 7.5N/mm2.<br />

Effects of steel fiber on specimens are not<br />

separately discussed. Since the steel fibers are<br />

used, there will be some percentage improvement<br />

in strength parameters.<br />

Steel fibres are incorporated in the pervious<br />

concrete mixes to improve their crack resistance,<br />

ductility, energy absorption and impact resistance<br />

ROAD RESEARCH IN INDIA 2011-12 119<br />

characteristics. Since, the diameter of steel fibre<br />

is 1 mm, there is no much difference in effect of<br />

permeability as only a little percentage amount of<br />

steel fibre is used.<br />

Codes/Specifications<br />

Delatte (2008) presents a set of design tables for<br />

the pervious concrete pavements, having a flexural<br />

strengths 2.1 - 3.1 N/mm 2 , as a part of light-duty<br />

pavement design. Based on the results of the present<br />

investigation, those mixes that have a 28-day flexural<br />

strength more than 2.1 N/mm 2 can be recommended<br />

for the design of light-duty pavements or low-volume<br />

traffic pavements.<br />

National Institute of Technology, Tiruchirappalli<br />

Scope and Objectives<br />

In future development of this area above the tunnel, if it<br />

is a road when vehicles pass through it, loads of those<br />

vehicles may finally acts upon the tunnel. But for the<br />

present stress calculations the tyre load effect is not<br />

considered. The load effect depends upon the height of<br />

the soil above the tunnel. At higher thickness of the soil<br />

above the tunnel, the wheel effect is minimum and at<br />

lower thickness the tyre load plays an important role for<br />

the development of stress in the tunnel lining. So the<br />

effect of wheel load should be taken into consideration.<br />

The objectives are<br />

•<br />

•<br />

To assess the wheel load stress acting over the<br />

pavement, which finally comes to tunnel, by<br />

The model analysis was done by preparing the model,<br />

obtained. Both these results were then compared.<br />

Salient-Findings and conclusion(s)<br />

By decreasing the height of the soil above the tunnel,<br />

the surcharge pressure coming over the tunnel is<br />

decreasing, but if a road comes over a tunnel due to<br />

the reduction of soil thickness above the tunnel, wheel<br />

loads has more significance. The effect of wheel load<br />

changes by various factors like height of soil, pavement<br />

thickness etc. compared to the flexible pavement<br />

the stress value is higher in case of rigid pavement<br />

conditions and while considering the direction of wheel<br />

loading, the wheel load perpendicular to the direction of<br />

major axis of tunnel induce almost double stress than<br />

the parallel loading condition in both rigid and flexible<br />

CSIR-Structural Engineering <strong>Research</strong> Centre,<br />

Chennai<br />

Scope and Objectives<br />

The objective of this research is to develop<br />

experimental techniques and methodologies to assess<br />

the in-situ stress in concrete and prestressed concrete<br />

structural elements under uniaxial- and biaxial- stress<br />

conditions.<br />

Proposed Methodology<br />

laboratory study.<br />

Salient-Findings and Conclusions<br />

Three different techniques namely, concrete coredrilling<br />

technique, concrete core trepanning technique<br />

and concrete core-drilling strain gage technique were<br />

developed to evaluate the in-situ stress under uniaxial<br />

and biaxial stress conditions.<br />

A concrete core-drilling technique was developed<br />

by considering the practical aspects of the strain<br />

gage instrumentation using a special arrangement<br />

of electrical resistance strain gages suitably placed<br />

around the core for assessment of in-situ stress under<br />

uniaxial stress condition. laboratory studies were<br />

conducted to evaluate the reliability of this concrete<br />

core drilling technique. Calibration constants were<br />

evaluated experimentally for the used gage length,<br />

location and configuration. Comparison was also made<br />

with coefficients evaluated theoretically.<br />

Concrete core trepanning technique was developed<br />

to measure in-situ stresses in concrete under bi-axial<br />

stress state. This technique employs a three element<br />

strain gage rosette to measure the strain release<br />

due to core drilling. Numerical analysis was carried<br />

out using finite element method for evaluating the<br />

efficacy of the method. The reliability of this technique<br />

was established in the laboratory, by conducting<br />

experimental investigations on ten concrete specimens<br />

with known stress/strain field.<br />

Core-drilling strain gage (CDSG) technique was<br />

developed by suitable placement of electrical resistance<br />

strain gages around the core for assessment of insitu<br />

stress. Six strain gages were used, where three<br />

strain gages placed radially and the remaining three<br />

placed tangentially to the indented core. Experimental<br />

studies were carried out to assess the existing stresses<br />

with a known stress field using the core-drilling strain<br />

gage technique. Calibration constants were evaluated<br />

experimentally and compared with numerical results<br />

(Finite element method). The applied stresses and<br />

existing stresses obtained from core drilling strain<br />

gage technique using the calibration constants were<br />

matching closely.<br />

From the numerical studies and laboratory experiments<br />

have clearly indicated that the proposed techniques are<br />

efficient in assessing the existing stresses. Hence, these<br />

techniques can be used for in-situ stress evaluation of<br />

in-service structures under uniaxial and biaxial stress<br />

conditions.<br />

2 Application of Pushover Analysis to RC<br />

Bridges<br />

Date of Start and Duration : Jan. 2011<br />

Date of Completion : Jun 2011<br />

Scope and Objectives<br />

Standard pushover analysis using FEMA 356 (2000)<br />

displacement coefficient method and an improved<br />

upper bound pushover analysis method were used to<br />

analyse a bridge structure.<br />

Proposed Methodology<br />

Analytical study.<br />

Salient-Findings and Conclusions<br />

After 2001 Gujarat Earthquake and 2005 Kashmir<br />

Earthquake, there is a nation-wide attention to the<br />

seismic vulnerability assessment of existing buildings<br />

and bridges. The aim of the project was to carry out a<br />

seismic evaluation case study for an existing RC bridge<br />

using nonlinear static (pushover) analysis.<br />

Bridges extend horizontally with its two ends restrained<br />

and that makes the dynamic characteristics of bridges


124<br />

different from building. Modal analysis of a 3D bridge<br />

model reveals that it has many closely-spaced modes.<br />

Participating mass ratio for the higher modes is very<br />

high. Therefore, pushover analysis with single load<br />

pattern may not yield correct results for a bridge<br />

model.<br />

A 12-span existing RC bridge was selected for the<br />

case study. Standard pushover analysis using FEMA<br />

356 (2000) displacement coefficient method and an<br />

improved upper bound pushover analysis method were<br />

used to analyse the structure. Some of the analysis<br />

parameters were suitably modified to use in a bridge<br />

structure. The evaluation results presented here shows<br />

that the selected bridge does not have the capacity to<br />

meet any of the desired performance level.<br />

3 Experimental Study of RC Beams<br />

Strengthened with CFRP Fabric under Pure<br />

Torsion<br />

Date of Start and Duration : August 2010<br />

Date of Completion : : Jun 2011<br />

Scope and Objectives<br />

The objective of the study is to understand the<br />

behaviour of torsion deficient RC rectangular beam<br />

specimens strengthened using carbon fabric in relation<br />

to the reference beam, which is designed for torsion<br />

Also, in this study attempts were made to understand<br />

the complexity of twist angle, torque and ductility of<br />

strengthened beams.<br />

Proposed Methodology<br />

laboratory Study<br />

Salient-Findings and Conclusions<br />

Torsional failure of a RC Beam is an undesirable brittle<br />

failure. In this study, two specimens were tested,<br />

PTR-1 (reference beam designed for torsion ) and<br />

PTT-1 (Beam deficient in torsion). The span and size<br />

of the both the beams were 1.79m and 150 x 250 mm<br />

GENERAl REPORT ON<br />

respectively. The beam- PTT-1 was strengthened using<br />

CFRP fabric strip (400 g/m 2 - Unidirectional, thickness<br />

0.234mm) of U-shaped 50 mm wide with spacing of<br />

75 mm c/c. Electrical strain gauges (120±0.4 Ω) were<br />

provided at quarter, middle and three quarter span<br />

of the beam, on top and bottom of the longitudinal<br />

reinforcement, at the centre of vertical stirrups and on<br />

CFRP-Fabric to measure the strains during testing of<br />

the beam. During the laboratory investigations, it was<br />

seen that the failure of beam PTR-1 was due to crushing<br />

of concrete and yielding tension steel. The specimen<br />

PTT-1 failed due to failure of anchorage, debonding<br />

of the CFRP fabric strips, yielding of reinforcement<br />

provided in compression zone at mid span and finally<br />

due to crushing of the concrete. The torsional capacity<br />

based on the strain recorded in the CFRP fabric during<br />

the experiment shows the good agreement with the<br />

theoretical values. The significant increase of twist<br />

angle of 151% and 44% was observed corresponding<br />

to cracking torque and ultimate torque respectively. The<br />

internal longitudinal steel was observed to be yielded<br />

to both the cases. The torsional capacity of the PTT-1<br />

exhibited 58% enhancement of torsional capacity with<br />

the application of CFRP fabric for strengthening. .<br />

recommendations for Dissemination/ revision of<br />

Codes/Specifications<br />

Based on the study it was concluded that the carbon<br />

FRP wrap could be used for the strengthening of RCC<br />

beams deficient in torsion after exercising proper care<br />

in the design of the rehabilitation scheme<br />

1. Study of Traffic Impacts of Construction Work<br />

Zones Using Simulation<br />

Date of start and duration: February, 2009<br />

Date of completion (Targeted): March, 2013<br />

National Institute of Technology, Tiruchirappalli.<br />

Scope and Objectives<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

The objectives of the study are:<br />

To study the traffic flow Characteristics of work zone<br />

and develop speed-flow, speed-occupancy model<br />

criteria for work zones during different stages of<br />

<strong>Highway</strong> widening under mixed traffic condition.<br />

To study the effect of Speed on length, width and<br />

Surface characteristics of work zones due to lane<br />

closure.<br />

To determine the reduction in Volume due to work<br />

zones and quantify delay associated to speed<br />

reduction in work zones corresponding to lane<br />

closure, length and percentage of heavy vehicles<br />

during different stages of construction.<br />

To develop a simulation model of work zone using<br />

VISSIM software and predict the vehicle throughput,<br />

average speed, travel time, and delay.<br />

To determine the delay road user costs of work<br />

zone.<br />

Methodology<br />

The research methodology is to be carried out in three<br />

Phases:<br />

phase I: work sites were identified and data collected<br />

in four zones (Advance Warning Zone, Approach<br />

transition zone, Work zone and Terminal transition<br />

zone) during three stages of Construction. The traffic<br />

parameters were analysed during three stages and<br />

their inter relationship between speed, flow, occupancy,<br />

headway, carriageway width and composition of traffic<br />

have been established. The surface charactersistics of<br />

the pavement and their relation with the speed reduction<br />

were analyzed and established.<br />

phase II: consists of Simulation modelling of work zone<br />

in VISSIM and its Validation.<br />

phase III: The scenario analysis of the model is to<br />

be done to find the effect of varying width, length,<br />

directional split and the composition of the traffic on<br />

speed, headway and delay during different stages .The<br />

capacity reduction in different stages have to estimated<br />

by the Time headway method and the Volume method<br />

GENERAl REPORT ON<br />

considering 15 min time interval and the above two<br />

methods will be compared with the one obtained<br />

through VISSIM. The monetary value of associated<br />

delay will be calculated.<br />

Salient-Findings and conclusions<br />

•<br />

•<br />

•<br />

•<br />

•<br />

It was observed that there was speed reduction in<br />

different category of vehicles from Stage-I to II due<br />

to the transition zones and newly laid road caused<br />

increase in speeds in stage III.<br />

The speed of the vehicle drops significantly while<br />

entering the construction zone. On the basis of<br />

the results from the study, speed of the vehicle is<br />

more in the advance warning zone and decreases<br />

as it enters the approach transition zone and then<br />

decreases further in the activity zone and increases<br />

again in the terminal transition zone. The average<br />

speed of the vehicles at the transition zone of the<br />

construction area was reduced by 60 % of the<br />

speed at the advance warning area.<br />

A statistical analysis confirms the differences in<br />

mean speeds are statistically significant in the<br />

advance warning zone and terminal transition zone<br />

in all vehicle categories at the 95% confidence level<br />

both in stage II and stage III respectively in spite of<br />

increase in mean speed in stage III.<br />

Average speeds of different categories of vehicle<br />

obtained from the VISSIM model were found<br />

comparable with that obtained experimentally in all<br />

the three stages of construction.<br />

With the increase in length of the work zone, speed<br />

increases and after a certain length of the work<br />

zone, the speed remains constant. This particular<br />

length of the work zone beyond which the speed<br />

remains constant is termed as ‘Critical length’.<br />

The critical lengths of the work zone obtained from<br />

the VISSIM model are 790 m and 780 m for Stage<br />

– II and III respectively which are more than the<br />

ones obtained experimentally (730m and 710 m<br />

respectively).<br />

2. Capacity Analysis of Three Legged Signalized<br />

Intersection using Cellular Automata<br />

Date of Start: August 2010.<br />

Date of Completion: August 2011.<br />

College of Engineering, Trivandrum (R)


Scope and Objectives<br />

The cellular automaton concept is used to simulate the<br />

traffic flow at a three legged signalized intersection.<br />

A Cellular Automata (CA) model is developed for the<br />

movement of the vehicles under heterogeneous traffic<br />

conditions. The stopping of vehicles at the signal<br />

controlled intersection and discharge of vehicles into<br />

the intersection during green time was simulated. The<br />

lane group capacity of the intersection was determined<br />

on each of the intersection approaches. Simulation<br />

results show the ability of the model to capture most<br />

important features of traffic phenomenon.<br />

The present study was undertaken with the following<br />

objectives:<br />

3. Evaluation of Roundabouts versus<br />

Unsignalized and Signalized Intersections in<br />

Trivandrum City<br />

Date of Start: August 2010.<br />

Date of Completion: July 2011.<br />

College of Engineering, Trivandrum (R)<br />

Scope and Objectives<br />

1. To analyse the performance of roundabouts<br />

against an unsignalized and signalized<br />

intersections under varying volumes based on<br />

certain measures of effectiveness.<br />

2. To obtain the traffic volume ranges at which<br />

roundabouts perform better than unsignalized<br />

and signalized intersections.<br />

The performance measures or measures of<br />

effectiveness (MOE’s) are capacity, degree of saturation,<br />

average control delay, 95 th percentile queue length and<br />

emissions (Carbon dioxide (CO2), Hydrocarbons (HC),<br />

Carbon monoxide (CO) and Nitric oxides (NOx).The<br />

present study was limited to 3-legged and 4-legged<br />

roundabouts with 2-lane approach from every direction.<br />

These two types of intersections were selected since<br />

they were the common types observed.<br />

Data collection, which includes geometric<br />

measurements of the existing roundabout<br />

intersection using a measuring tape and video<br />

recording for 5 days of a week to obtain the traffic<br />

details.<br />

Traffic volume with proportion of turning movement<br />

was extracted from the video. The video was played<br />

and the total number of specific type of vehicle in<br />

each direction was obtained manually.<br />

Traffic volume was divided to 15min datasets<br />

(total inlet volume with proportion of each turning<br />

movements). 15min data was inputted into the<br />

SIDRA software. Hence a total of 120 datasets<br />

were obtained<br />

Geometric features measured and extracted traffic<br />

data was the input to the SIDRA software.<br />

Various performance measures were obtained<br />

after analysis from the SIDRA software.<br />

Traffic volume range at which roundabout has better<br />

performance than other types of intersections was<br />

determined.<br />

Findings/Conclusions<br />

•<br />

•<br />

•<br />

•<br />

The capacity of uncontrolled and roundabout<br />

intersections was found to reduce with increasing<br />

inlet volume.<br />

The capacity of a signalized intersection had only<br />

slight variation up to a total inlet volume of 2500vph<br />

and 3500vph for 3-legged and 4-legged roundabout<br />

respectively and thereafter increased rapidly.<br />

The degree of saturation of uncontrolled and<br />

roundabout intersections increased with total inlet<br />

volume.<br />

The degree of saturation of signalized intersection<br />

increased rapidly till total inlet volumes for which<br />

capacity remained unchanged, then decreased<br />

and thereafter remained a constant value.<br />

GENERAl REPORT ON<br />

• The average<br />

control delay at an uncontrolled<br />

intersection was higher than roundabout at all<br />

volumes. Hence based on delay, performance<br />

of roundabout was better than uncontrolled<br />

intersection.<br />

•<br />

•<br />

•<br />

•<br />

The average control delay of signalized intersection<br />

remained unchanged till 2000vph for 3-legged<br />

as well as 4-legged intersection and thereafter<br />

increased gradually.<br />

When the traffic volume was low, vehicles at<br />

uncontrolled intersections produced lesser pollution<br />

than other two types of intersections.<br />

At lower inlet volumes, vehicles at signalized<br />

intersection produced greater emissions compared<br />

to other two types of intersection due to compulsory<br />

stopping of vehicles. But at higher total inlet volumes<br />

vehicles at signalized intersection produced lesser<br />

emissions due to orderly movement of traffic and<br />

due to the absence of frequent acceleration and<br />

deceleration of vehicles.<br />

A 3-legged roundabout with 2-lane approach<br />

was found to perform better than other two types<br />

of intersections at a total inlet volume of 872 to<br />

4143 vph while a 4-legged roundabout with 2-lane<br />

approach performed better at the total inlet volume<br />

range of 1163 to 5524 vph.<br />

on Selected Route Pairs in Trivandrum City<br />

Date of Start: August 2010.<br />

Date of Completion: July 2011.<br />

College of Engineering, Trivandrum (R)<br />

Scope and Objectives<br />

The specific objectives of this study are:<br />

•<br />

•<br />

To compute the Travel Time Reliability indices such<br />

as Buffer Time Index and Planning Time Index of<br />

different routes in a few selected route pairs at<br />

Trivandrum.<br />

To identify the most reliable routes among several<br />

selected routes connecting route pairs by comparing<br />

its reliability indices.


•<br />

•<br />

•<br />

To model congestion on these routes by relating<br />

the reliability indices to congestion.<br />

To study the influence of various geometric and<br />

traffic factors on the variation of travel time and to<br />

model it.<br />

To predict the travel time of these routes using<br />

Artificial Neural Network.<br />

Methodology<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

Selection of study stretch – Two route pairs were<br />

selected in this study which are Ulloor- Pattom<br />

route pair and Thirumala- Vazhuthacaud route pair<br />

Data Collection – Videographic recording and<br />

license plate matching method<br />

Data Extraction – time taken to travel through<br />

different routes in the route pair by car at different<br />

times of the morning peak hours<br />

Calculation of Travel Time Reliability Indices like<br />

Planning Time Index and Buffer Time Index<br />

Comparison of TTR Indices of different routes in the<br />

route pair and finding out the reliable route in the<br />

route pair and reliable times for travelling through<br />

these routes.<br />

The relation between travel time reliability and<br />

congestion was established with Planning Time<br />

Index and Travel Time Index were used as the<br />

indicators for travel time reliability and congestion<br />

respectively.<br />

Travel Time Variability was modelled with Planning<br />

Time Index as the dependent variable and various<br />

geometric and traffic factors as independent<br />

variables.<br />

Travel times on these routes were predicted using<br />

Artificial Neural Network<br />

Findings/ Conclusions<br />

•<br />

•<br />

•<br />

From the comparison of travel time reliability indices<br />

calculated for Ulloor- Pattom route pair, route via<br />

Kesavadasapuram is found to be more reliable<br />

than the other route in the morning peak hours.<br />

For Ulloor- Pattom route pair, route via Medical<br />

College shows a wide variation in travel time<br />

reliability indices on both Monday and Wednesday.<br />

But the variation of travel time reliability indices<br />

for route via Kesavadasapuram on Monday and<br />

Wednesday is almost constant.<br />

From the comparison of travel time reliability indices<br />

calculated for Vazhuthacaud- Thirumala route pair,<br />

route via Pangode is found to be more reliable than<br />

the other route in the morning peak hours.<br />

ROAD RESEARCH IN INDIA 2011-12 131<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

In both the above cases, the driver perception<br />

towards selection of reliable route was due to<br />

shorter length and good surface conditions.<br />

Day wise comparison shows that the travel time on<br />

Monday is unpredictable than that on Wednesday.<br />

The relation between travel time reliability and<br />

congestion is established. From the plot of Planning<br />

Time Index vs Travel Time Index, an upward trend<br />

was found to be existing between the travel time<br />

variability and congestion.<br />

As the traffic volume of the stretch increases,<br />

variability in travel time also increases due to the<br />

uncertainty which results in the reduction of travel<br />

time reliability.<br />

A Multiple linear Regression Model was developed<br />

connecting the Planning Time Index as dependent<br />

variable and different geometric and traffic factors<br />

as independent variables. Travel time variability<br />

decreases with increase in free flow travel time and<br />

average width of the road.<br />

Travel time variability increases with increase in<br />

length of the link, number of secondary intersections,<br />

traffic volume and percentage of cars increases.<br />

ANN is found to be effective in predicting the<br />

travel times on these routes. Travel time prediction<br />

models for considered routes in the route pairs<br />

were developed using Artificial Neural Network<br />

(ANN).<br />

5. Impact of Traffic Composition on PCU Values<br />

of Road Vehicles<br />

Date of Start and Duration: December 2009, 3<br />

years , Date of Completion: on-going<br />

<strong>Indian</strong> Institute of Technology Madras, Chennai<br />

- 600 036<br />

Scope and Objectives<br />

The principal objective of the work proposed here is<br />

to study the possible variation of Passenger Car Unit


132<br />

(PCU) values of different categories of vehicles due to<br />

changes in traffic composition, under heterogeneous<br />

traffic conditions prevailing on <strong>Indian</strong> roads. The<br />

available simulation model will be used to derive<br />

Passenger Car Unit (PCU) values for different types<br />

of vehicles under the prevailing traffic condition. The<br />

effect of variation of traffic composition on PCU value<br />

will be studied by deriving PCU values for the different<br />

types of vehicles for a set of vehicle composition falling<br />

over a wide range.<br />

Proposed Methodology<br />

The PCU values for the different types of vehicles, at<br />

various volume levels and vehicle composition, will be<br />

estimated by taking the average stream speed as the<br />

measure of performance. Accordingly, the stream speed<br />

of the heterogeneous traffic of chosen composition for a<br />

chosen volume and composition will be first determined.<br />

Then certain percentage of cars will be replaced by<br />

the reference vehicle type in the mixed traffic stream,<br />

such that the average stream speed remains the same<br />

as before the introduction of the additional reference<br />

vehicles in the stream. This can be achieved by varying<br />

the number of the reference vehicles introduced to<br />

substitute the removed cars until the original speed<br />

of the traffic is obtained by simulation. Then, the<br />

number of cars removed divided by the number of<br />

introduced reference vehicles will give the PCU value<br />

of that vehicle type. This procedure will be repeated for<br />

different volume levels and vehicle composition falling<br />

over a wide range. A recently developed microscopic<br />

simulation model of highly heterogeneous traffic flow<br />

named HETEROSIM was used for the analysis.<br />

Salient-Findings and Conclusions<br />

It is found that, under heterogeneous traffic conditions,<br />

for a given roadway condition and traffic composition,<br />

the PCU value of vehicles varies significantly with<br />

change in traffic volume and composition. Hence, it<br />

is desirable to treat PCU as dynamic quantity for the<br />

different vehicle categories.<br />

Conclusions and recommendations<br />

Salient-Findings and Conclusions<br />

1. For non-lane-following case, when the volume<br />

is less than or equal to 1500 pCU/h, the traffic<br />

composition does not make much difference on<br />

the delays at the intersection. If the volume is<br />

greater than 2000 pCU/h and if cars composition<br />

is also increasing in traffic the delay of vehicles<br />

are increasing due to more space acquirement<br />

by cars, lower dissipation rate of cars compared<br />

to two wheelers, filtering of two wheelers is lesser<br />

between gaps even if its’ composition is lesser.<br />

2. For vehicles with lane following, when the volume<br />

is less than 1000 pCU the traffic composition don’t<br />

make much difference on the delay of intersection.<br />

3.<br />

4.<br />

5.<br />

For lane following case, if two wheelers composition<br />

is predominant, maximum number of vehicles<br />

crossing the stop line at intersection is 1500 PCU.<br />

For this case, when car composition is increasing<br />

the delay of the intersection is increasing compared<br />

to two wheeler dominant composition.<br />

For lower volume levels, the overall delay of<br />

vehicles is greater in lane following case scenario<br />

compared to non-lane following scenario.<br />

The dissipation of vehicles in PCU per cycle from<br />

field and simulation model is statistically significant<br />

and the percentage of error between field and<br />

simulation is 5%, which shows that the simulation<br />

model reasonably represent the heterogeneous<br />

traffic conditions.<br />

8. Analysing The Relation Between Land Use<br />

And Travel Demand Using 3s Technology.<br />

Date of start and duration 15 th JUlY 2011, .<br />

Date of completion 30 th MAY 2012<br />

National Institute Of Technology,Tiruchirappalli<br />

Scope and Objectives<br />

3S technology is the integration of three technologies.<br />

ie RS (remote sensing), GPS (Global positioning<br />

system) and GIS (geographic information system).The<br />

motivation for incorporating 3S data into travel demand<br />

modelling stems from its apparent relevance to problems<br />

ROAD RESEARCH IN INDIA 2011-12 133<br />

that require large scale and highly dimensional data<br />

analysis.<br />

The objectives are:<br />

• To extract<br />

land use of the wards of Tiruchirappalli<br />

city using RS and GIS.<br />

•<br />

•<br />

•<br />

•<br />

•<br />

To find trip generation and trip attraction of all wards<br />

of Tiruchirappalli city using GIS,<br />

To estimate an origin destination matrix based on<br />

land use status.<br />

To assess the performance by comparing the<br />

assigned traffic volume with the actual traffic<br />

volume based on link volume counts.<br />

To assign the estimated O-D to the existing road<br />

network so that demand for traffic between every<br />

pair of zones is allocated to available routes.<br />

To develop a travel demand model using CUBE and<br />

compare the results of the land use model with the<br />

traditional model developed using the software.<br />

Proposed Methodology (Type of study, Laboratory/<br />

Field)<br />

From the land use extracted, trip production and trip<br />

attraction are calculated by land use method and the<br />

obtained trips are compared with the base year matrix<br />

of 2003 to develop the O-D matrix for 2012. The data<br />

was collected, image classification was done, trip<br />

generation and trip attraction was found and travel<br />

demand was calculated by estimating an O-D matrix<br />

after generating trip generation and trip attraction.<br />

The obtained matrix is validated by link volumes and<br />

compared with the traditional model developed using<br />

CUBE 6.<br />

Salient-Findings and conclusion(s)<br />

• The<br />

O-D matrix of 2012 shows an increase of<br />

almost nine times travel demand compared to the<br />

base year matrix of 2003 and the validated results<br />

shows a RMSE of 5%<br />

•<br />

•<br />

3S technology helps in updating the land use and<br />

hence travel demand estimation will be easier<br />

compared to the traditional method since changes<br />

in land use pattern cannot be easily incorporated in<br />

the traditional model.<br />

The accuracy of estimation of O0D matrix from the<br />

traditional model would have been improved if more<br />

parameters have been included, but collection of<br />

these data are very difficult when compared to the<br />

land use method.

Creation of control hierarchy for FAHP and<br />

network for FANP involving the criteria and sub<br />

criteria.<br />

The fuzzy pair-wise comparison matrices with<br />

fuzzy-ratio judgments were formed according<br />

to the control hierarchy or network developed.<br />

Triangular fuzzy weights were derived from<br />

fuzzy pair-wise comparison matrices.<br />

After calculating the triangular fuzzy weights,<br />

the fuzzy evaluations of the alternative modes<br />

were derived.<br />

The alternative modes were then ordered by<br />

using the maximum membership principle of<br />

defuzzification and the transportation mode<br />

with highest priority was chosen.<br />

Validation of the FAHP model and FANP model<br />

was done by comparing the final results with the<br />

actual mode choice proportion obtained from the<br />

main questionnaire survey<br />

A gap analysis procedure was carried out using the<br />

FAHP model in Expert Choice software to find out the<br />

change in mode choice behaviour and the possible<br />

modal shift from other modes if an ideal mode like<br />

BRTS is introduced.<br />

Findings/Conclusions<br />

Following conclusions were drawn from the preliminary<br />

survey:<br />

•<br />

•<br />

The parameter ‘Route of travel’ is not affecting the<br />

mode choice behaviour of work trip commuters as<br />

most of them are using the same route during the<br />

trips<br />

The parameter ‘Time under which journey is<br />

undertaken’ is also not affecting the mode choice<br />

behaviour of work trip commuters since they are<br />

carrying out the during the morning and evening<br />

peak hours and similar conditions exist during<br />

these hours.<br />

Following conclusions were drawn from the FAHP and<br />

FANP models:<br />

•<br />

•<br />

The fuzzy weights of criteria clusters showed<br />

that the socioeconomic characteristics was more<br />

important than trip and system characteristics while<br />

choosing a mode<br />

Among the socio-economic characteristics, income<br />

and vehicle ownership were the main factors<br />

affecting mode choice


•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

Similarly among trip characteristics, travel distance<br />

and travel cost were affecting mode choice than<br />

travel time<br />

Among system characteristics, comfort &<br />

convenience and reliability were the main factors<br />

affecting mode choice<br />

The results from the FAHP and FANP model<br />

showed that the transportation mode with highest<br />

priority was bus followed by two wheeler and car.<br />

FANP model was more accurate compared to<br />

FAHP model as it was more close to actual mode<br />

choice proportion with lesser RRMSE of 0.425%<br />

The gap analysis using Expert Choice indicate<br />

there is a possible modal shift from existing modes<br />

to an ideal mode like BRTS if an ideal mode is<br />

introduced in the city and it showed that the mode<br />

choice proportion of BRTS will be 0.421<br />

The possible modal shift from bus will be greater<br />

than that from other modes to ideal mode by<br />

Date of completion 30 th MAY 2012<br />

National Institute of Technology, Tiruchirappally<br />

Scope and Objectives:<br />

The main objectives of this project are:<br />

•<br />

To develop speed-flow relationships for construction<br />

work zone<br />

GENERAl REPORT ON<br />

• To estimate the delay caused by the speed<br />

reduction in construction work zone<br />

•<br />

•<br />

•<br />

To estimate the work zone impacts on travel delay<br />

and vehicle operation<br />

To compute the unit cost for each impact<br />

To estimate the road user cost<br />

Proposed Methodology (Type of study, Laboratory/<br />

Field)<br />

The project work started with the pilot study followed<br />

by selection of sites for the actual survey work in rural<br />

and urban areas. Data collection was done using<br />

Registration Number Plate method. Then Speed and<br />

Journey time was determined and Speed-Flow curve<br />

was obtained through which delay through work zone,<br />

impacts on work zone, unit cost on each impact was<br />

found and Road user cost was estimated.<br />

Salient-Findings and conclusions<br />

The conclusions derived from results are<br />

•<br />

•<br />

•<br />

The speed of the vehicles drops significantly while<br />

entering the construction zone. Variation of speed<br />

in the advance warning zone is less compare to<br />

the freeway speed without construction zone. The<br />

average speed of vehicle is more in the advance<br />

warning zone, decreases as it enters the approach<br />

transition zone and work zone and then increases<br />

in terminal zone. The speed of the vehicles at the<br />

transition zone was reduced by 60% compare to<br />

the advance warning area<br />

With the increase in road width, as speed increases<br />

and intern it decreases the road user cost.<br />

Delay cost is the most significant factor in the road<br />

user cost. With the difference of 4 km/hr RUC is<br />

increasing at a rate of 40%. With the increase in<br />

length road user cost is increasing at a constant<br />

rate. The change of length and width of road it<br />

directly affects the travel time and vehicle operating<br />

cost.<br />

12. Impact of Land Use on Trip Generation- A<br />

Case Study<br />

Date of Start: July 2010.<br />

Date of Completion: July 2011.<br />

College of Engineering, Trivandrum (R)


Scope and Objectives<br />

The process of urban development is leading to<br />

highly unsustainable urban sprawl by the migration of<br />

population from rural to urban areas and thus changing<br />

small population centres to large metropolitan cities.<br />

In the urban system, land development generates<br />

travel, and travel generates the need of new facilities,<br />

which in turn increases accessibility and attracts further<br />

development. Hence, there is a constant interrelation<br />

between land use, demography and transportation,<br />

the knowledge of which will be helpful in knowing the<br />

generation of traffic. In the present study, an attempt<br />

was made to assess the land use characteristics of<br />

a semi urban city with the main objective to estimate<br />

the trip generation due to new basic employment.<br />

Future developments will create new employments in<br />

the basic sector which in turn influences the spatial<br />

distribution of the population and service employment.<br />

The effect of new employment on trip generation has to<br />

be studied. The Technopark, a major business centre<br />

in Trivandrum is located at the borders of Kazhakuttom<br />

block. There are plans for the expansion of Technopark.<br />

The impact of such an expansion on transportation has<br />

to be studied. Hence the scope of this work is limited<br />

to Kazhakuttom block in Trivandrum district. The study<br />

area will have to cater to the projected traffic.<br />

The following are the objectives of the study.<br />

•<br />

•<br />

•<br />

•<br />

To study the existing land use of the study area<br />

To analyse the land suitability for the study area<br />

To develop a land Use Model based on Garinlowrys’<br />

concept<br />

To analyse the impact of expansion in basic<br />

employment on trip generation<br />

Methodology<br />

•<br />

•<br />

•<br />

•<br />

Identification of the study area- Kazhakuttom block<br />

in Trivandrum district is selected as the study<br />

area.<br />

Collection of data -Primary data like socio-economic<br />

data, travel characteristics was collected by<br />

conducting interviews and surveys and secondary<br />

data like demographic data, employment data,<br />

existing land use network pattern etc. was also<br />

collected.<br />

Analysing the land suitability of the study area<br />

and development of land use model. By using<br />

the software ArcGIS, the land suitability for the<br />

study area was carried out to analyze suitability of<br />

development.<br />

A program in MATlAB was written to obtain the<br />

generated population and service employment for<br />

new basic employment.<br />

• Estimation of trip generation using TransCAD<br />

software. Category analysis was used for estimating<br />

trip production and regression model was used for<br />

trip attraction.<br />

Findings/Conclusions<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

The majority of land use in the study area is<br />

agricultural which constitutes about 69%. Forest<br />

area constitutes around 0.2% and water body<br />

constitutes around 3.4%. Residential area is about<br />

5% of the total area.<br />

Weighted overlay analysis showed that about 7 %<br />

of the total area is restricted for any development.<br />

The percentage of land which is h i g h l y<br />

suitable was found to be 21%.<br />

The area required for the projected number of<br />

households in the year 2020 was found to be 5.96<br />

sq.km and the area available for development<br />

was19.72 sq km.<br />

The total generated population of the study area<br />

due to a new basic employment is 2, 22, 034 which<br />

was within the maximum holding capacity.<br />

Total trips produced in the study area were 19,1945<br />

trips/day and the total trips attracted to the study<br />

area were found to be 12,7859 trips/day.<br />

It was seen that by 2020, the rate of growth of trip<br />

production is about 15% and the rate of growth of<br />

trip attraction to the study area is 7.5%.<br />

13. Algorithms for Reliability Based Optimal<br />

Routing and Traffic Assignment in Stochastic<br />

Transportation Networks<br />

Date of Start and Duration: 21-06-2007, 5<br />

years<br />

<strong>Indian</strong> Institute of Technology Madras, Chennai<br />

- 600 036<br />

Scope and Objectives<br />

1. Most reliable shortest paths: To characterize the<br />

different measures of reliability at the link/path<br />

level, and


138<br />

a. Formulate the most reliable travel time path<br />

(orp) problem on a network with random and<br />

correlated link travel times, and develop an<br />

algorithm to solve this ORP problem; examine<br />

computational performance of proposed<br />

algorithm on synthetic networks..<br />

b. Application: To model, calibrate and quantify<br />

the distribution of travel times, and apply the<br />

developed ORP algorithm to the Chennai road<br />

network.<br />

2. Robust Shortest paths:<br />

a. To formulate the optimal robust cost path<br />

problem (MRCP) on a network with random<br />

and correlated link travel times and propose/<br />

implement solution algorithms to compute<br />

the optimal robust cost path under various<br />

correlation structures; to examine computational<br />

performance of proposed algorithms on<br />

synthetic networks.<br />

b. Application: To model & calibrate the flow<br />

dependent distribution of link travel times,<br />

& apply the developed optimal robust path<br />

algorithms to the Chennai road network.<br />

3. Robust (Reliability Based) Traffic Assignment<br />

a. To propose a robust traffic assignment<br />

algorithm to compute the link traffic volumes on<br />

the network resulting from individual traveler’s<br />

choice of his/her optimal most robust/reliable<br />

path.<br />

b. To calibrate and validate the robust traffic<br />

assignment model for Chennai City.<br />

Proposed Methodology<br />

To address objective one and two, the various measures<br />

of reliability are first identified from the literature and<br />

their pros/cons are examined. Based on the suitability<br />

of the different measures for the present context, two<br />

measures of reliability, namely probability of on time<br />

arrival (travel time reliability) and robust cost (weighted<br />

combination of mean and variance of path travel time)<br />

are selected. Next, the most reliable path problem<br />

(ORP) and optimal robust cost path (MRCP) problem<br />

are formulated as integer non-linear programming<br />

problems.<br />

Optimality criteria are subsequently established for the<br />

formulated ORP/MRCP problems, based on which,<br />

first, an efficient algorithm combining simulation and<br />

network optimization is developed to compute the ORP<br />

on networks with stochastic correlated link travel times.<br />

The algorithm is illustrated for the case of multivariate<br />

normal and multivariate log normal link travel times.<br />

Next, an algorithm that applies a label correcting<br />

procedure for the multi criteria SP problem is proposed<br />

GENERAl REPORT ON<br />

and implemented to compute the MRCP on networks<br />

with stochastic link travel times under certain correlation<br />

structures. In addition, a pruning strategy within a label<br />

correcting procedure is proposed/ implemented to<br />

relax the previously imposed restrictions on correlation<br />

structure.<br />

After implementation of the solution algorithms,<br />

computational experiments are conducted to study<br />

their performance under different network conditions<br />

and user risk preferences. In addition, the impact of<br />

distributions, variability, correlations and risk attitudes<br />

for different metrics is investigated by studying their<br />

influence on the MRP at varying input levels.<br />

With regard to the tasks involved under objective three,<br />

the robust traffic assignment problem is first formulated<br />

as an equilibrium problem. A solution scheme will then<br />

be proposed that iteratively uses the MRCP algorithm<br />

developed under objective 2a. The developed<br />

algorithm is then applied to the Chennai network and<br />

calibrated suitably using, (1) Secondary travel time<br />

and volume data (2) Primary data from a questionnaire<br />

based stated/revealed preference survey. Suitable<br />

performance measures are to be then identified and<br />

the calibrated model is compared with existing static<br />

assignment models on suitable real world networks.<br />

Salient-Findings and Conclusions<br />

Questionnaire based stated preference route choice<br />

survey conducted (as part of Advanced Traveler<br />

Information Systems Survey) and 400 responses<br />

obtained from workers and non-workers in Chennai<br />

city.<br />

Development of reliability based route choice models<br />

from SP section. The coefficient of risk aversion<br />

was estimated for two wheeler/four wheeler users in<br />

Chennai city, and these estimates will be used in the<br />

empirical application of the robust assignment model.<br />

The coefficient of travel time for cars was found to be<br />

higher than that of 2 wheelers reflecting the fact that<br />

car users accord a higher value to time than 2-wheeler<br />

users. Consequently, car users are less averse to risk<br />

(DORA= 2.36) compared to 2- wheeler users (1.40).<br />

The use of the robust UE model and the significance<br />

of modeling reliability are illustrated using a simple<br />

example of evaluating the effect of an infrastructure<br />

improvement for the Sioux Falls Network. The two<br />

scenarios considered are:<br />

1. Base: Current existing network (Figure 1)<br />

2. Alternate: Existing network + new corridor/<br />

expressway (Infrastructure improvement)<br />

The salient findings from the experiment are summarized<br />

below:


• The results indicate<br />

that for the base scenario the<br />

robust user equilibrium solution has a marginally<br />

lower total system travel time with a reduction of<br />

0.8%<br />

•<br />

•<br />

•<br />

•<br />

On the other hand, the system variance reduces<br />

significantly by 27%.<br />

RUE flow solution as a benchmark improves on<br />

both the mean travel time and travel time reliability<br />

over the corresponding UE solution.<br />

For the alternate scenario, the increase in system<br />

capacity results in a significantly lower variability<br />

reduction at 5% whereas the reduction in mean<br />

travel time increases to 2%.<br />

Thus, in both cases the RUE solution improves<br />

on both the mean travel time and the travel time<br />

variability for the empirically estimated value of the<br />

risk aversion weight w=0.45.<br />

14. Application of Dynamic Traffic Assignment<br />

(DTA) Packages Under <strong>Indian</strong> Traffic<br />

Conditions<br />

Date of Start and Duration: August 3, 2010 - 3<br />

yrs, Date of Completion: Dec 2012<br />

<strong>Indian</strong> Institute of Technology Madras, Chennai -<br />

600 036<br />

Scope and Objectives<br />

In this research work, we propose to demonstrate<br />

detailed application of DTA in <strong>Indian</strong> traffic conditions.<br />

DTA models differ in the implementation of three<br />

components: they are network loading, path adjustment<br />

or traffic assignment, and path update. Most DTA<br />

applications have been developed for homogenous<br />

traffic conditions. However <strong>Indian</strong> traffic conditions<br />

are highly heterogeneous. Therefore the traffic flow<br />

modeling in network loading step of DTA needs to<br />

be suitably calibrated for <strong>Indian</strong> traffic conditions.<br />

Calibrating the network loading step accounting for<br />

mixed traffic conditions will be the primary objective of<br />

the proposed research work.<br />

Proposed Methodology<br />

laboratory<br />

Salient-Findings and Conclusion<br />

Models, after calibration, were able to reproduce<br />

field observed travel times and overall counts within<br />

reasonable accuracy<br />

Scope and Objectives<br />

Objectives:<br />

•<br />

•<br />

•<br />

To propose a system architecture best suited for<br />

heterogeneous traffic conditions.<br />

To study the major traffic components of the system<br />

with the help of field data.<br />

evaluation of ATC systems.<br />

GENERAl REPORT ON<br />

Scope:<br />

Traffic congestion is an ever increasing problem in<br />

towns and cities all over the world. Different approaches<br />

can be used to minimize the traffic problems in which,<br />

control of traffic light signal timings is one of the least<br />

expensive and most effective means of reducing<br />

vehicular congestion in metropolitan road networks.<br />

There is a requirement to optimize the current road<br />

model by properly allocating the time to traffic signals.<br />

Proposed Methodology (Type of study, Laboratory/<br />

Field)<br />

Cycle lengths and phase timings of all the intersections<br />

in the study area were collected from Chennai City<br />

Traffic Police (CCTP). The collected data were analysed<br />

to calculate the traffic load in PCU/12 hour for each<br />

intersection. Using the values of the traffic volumes,<br />

the signal timings were designed. Traffic information<br />

is transmitted to the central computer at the control<br />

centre and is processed to determine optimal signal<br />

timing. SCOOT performs optimization at three levels.<br />

SCOOT measures vehicles at a detector ideally placed<br />

at least eight seconds of travel time upstream from the<br />

stop line. Every second, the central program predicts<br />

the profile of arrivals to the signal based on the profile<br />

measured at the detector. TRANSYT was used in this<br />

study which attempts to model an approach to real-time<br />

control which is very similar to SCOOT.<br />

Salient-Findings and conclusions<br />

•<br />

•<br />

•<br />

The delays could be reduced in the Study<br />

Stretch during peak hours if the signals were<br />

synchronized.<br />

The time savings for the peak hour were multiplied<br />

by peak hour factor and the total number of vehicles<br />

in the stretch for obtaining the overall savings,<br />

which could be extended to the annual savings and<br />

in turn it reduces the road user cost.<br />

By introducing Adaptive Road Traffic Control<br />

system which may react dynamically based on the<br />

situation.<br />

National Institute of Technology, Tiruchirappalli.


Scope and Objectives<br />

Conventional survey and mapping techniques are<br />

expensive and time consuming for the estimation of<br />

urban expansion and such information is not available<br />

for most of the urban centers, especially in developing<br />

countries. As a result, increased research interest is<br />

being directed to the monitoring of urban growth using<br />

GIS and remote sensing techniques. GIS provides a<br />

flexible environment for collecting, storing, displaying<br />

and analyzing digital data necessary for change<br />

detection.<br />

In the past few years, there has been considerable<br />

infrastructural, industrial and transportation network<br />

development in Tiruchirappalli City but up-to-date<br />

information relating to lU/lC are frequently missing<br />

at the Municipal and State level and thus, an attempt<br />

will be made in this study to map out the status of lU/<br />

lC of Tiruchirappalli between 1992 and 2009 so as to<br />

detecting lU/lC changes and predict possible changes<br />

that might take place in the next nine years using both<br />

GIS, and RS data with the help of Markov model.<br />

The objectives of the study are:<br />

•<br />

•<br />

•<br />

•<br />

To quantify the amount of development along the<br />

study area, Tiruchirappalli City, by analysing the<br />

changes in the lU/lC, estimated using IRS and<br />

landsat imageries.<br />

To define the different classes from the images<br />

for the study area based on lU/lC classification<br />

system devised by National Remote Sensing<br />

Agency (NRSA) for <strong>Indian</strong> conditions, by visual<br />

interpretation and by using image processing<br />

software technologies and to find the classification<br />

accuracy.<br />

To estimate quantitatively the spatial and temporal<br />

changes in the lU/lC defined classes using multidated<br />

satellite images.<br />

To forecast the future changes in lU/lC and<br />

integrate in to Transportation Planning.<br />

Proposed Methodology (Type of study,Laboratory/<br />

Field)<br />

The research methodology is divided into 5 sections.<br />

They are collection of data, pre-processing, study area<br />

details; image classification and forecasting of land use<br />

and land cover change. This research addresses lU/<br />

lC changes over a 17 year period of study, 1992 to<br />

2009, in Tiruchirappalli city.<br />

The creation of lU/lC maps of Tiruchirappalli city for<br />

the years 1992 to 2009 were derived from three IRS<br />

images and four multi-temporal landsat TM and ETM+<br />

images. Markov model is used to forecast the lU/lC<br />

changes in Tiruchirappalli city. The image processing<br />

techniques employed in this study were conducted<br />

using ERDAS Imagine 9.1 image processing software.<br />

Methods in Mode Choice Analysis - A Case<br />

Study<br />

Date of Start: August 2011.<br />

Date of Completion: August 2012.<br />

College of Engineering, Trivandrum (R)<br />

Scope and Objectives<br />

<strong>Highway</strong>s constructed and maintained properly play a<br />

major role in nation’s development. Among pavement<br />

components, subgrade soil is considered as an integral<br />

part of pavements as it provides support to the pavement<br />

and hence subgrade soil and its properties are important<br />

in the design of pavement structure. India is a large<br />

country with varying terrain, climatic and environmental<br />

conditions. About 33% of the total land area in India is<br />

the Expansive soils. Most of the places in the district<br />

of Alappuzha in the state of Kerala have pavement<br />

and foundation problems due to the presence of weak<br />

clayey soils that are expansive in nature. Kuttanad<br />

region in Kerala is a unique agricultural area. A major<br />

portion of this area lies below mean sea level and is<br />

submerged under water for more than a month in every<br />

year during rainy season. The soil of Kuttanad region is<br />

entirely different from normal well drained soils in their<br />

morphological, chemical and physical characteristics.<br />

Thus construction of roadbeds on or with soils, which<br />

do not possess sufficient strength to support wheel<br />

loads imposed upon them either in construction or<br />

during the service life of the pavement is a commonly<br />

encountered problem. Such jobs are challenging for<br />

engineers because of the low shear strength of the<br />

foundation soil, which causes excessive consolidation<br />

settlement and bearing capacity failure.<br />

There are plenty of natural materials available such<br />

as jute, coir, sisal, bamboo, wood, palm leaf, coconut<br />

leaf truck, coir dust, cotton and grass, etc., for being<br />

used a soil reinforcement material to improve certain<br />

engineering properties of soil. Many researchers have<br />

explained the effect of coir reinforcement on various<br />

types of soil including expansive soils but only limited<br />

studies have been carried out on the use of sisal fibres,<br />

which is a natural fibre, as soil reinforcement and<br />

hence it will be worthwhile to investigate the efficiency<br />

of reinforcement of Kuttanad clay with sisal fibres, after<br />

lime stabilization. This study is intended to bring out


142<br />

the effectiveness of chemical stabilization and fibre<br />

reinforcement in clayey soils.<br />

The objective of the present study is to experimentally<br />

investigate the reinforcing effect of randomly distributed<br />

sisal fibres in Kuttanad clay. It is proposed to conduct<br />

the study after stabilizing the clay with lime. The<br />

load deformation behaviour of clay gets improved<br />

with surface friction between fibre and soil. Sand is<br />

considered as an efficient tool for the same. In order<br />

to efficiently use the fibres, the optimum fibre content<br />

and optimum fibre length have to be obtained. Detailed<br />

investigation is to be carried out to analyse the effect<br />

of reinforcement on the compaction and hence the<br />

strength characteristics of Kuttanad clay.<br />

The objective of the present study is to study the<br />

effect of chemical and mechanical stabilization on the<br />

properties of Kuttanad for being used as a subgrade.<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

Addition of lime resulted in decrease in MDD and<br />

OMC and an increase in CBR value.<br />

Maximum value of OMC is attained by a sisal fibre<br />

aspect ratio of 120 and fibre content of 1% and<br />

minimum value is attained by a fibre aspect ratio<br />

of 120 and fibre content of 1%, irrespective of sand<br />

content.<br />

Addition of river sand resulted in improvement in<br />

CBR value of Kuttanad clay.<br />

CBR value improves with fibre aspect ratio upto<br />

80 and fibre content of 0.75% and decrease<br />

thereafter.<br />

For a fixed sand content, maximum CBR increase<br />

is about 3 times for fibre content of 0.75% and fibre<br />

aspect ratio of 80 than fibre content of 0.75% and<br />

fibre aspect ratio of 60.<br />

Optimum content and fibre aspect ratio were 0.75%<br />

and 80 respectively.<br />

CBR value improves with increase in sand<br />

percentage. From economical point we can adopt<br />

7.5% as optimum sand content.<br />

Both stabilization and sisal fibre reinforcement<br />

resulted in considerable reduction in Swell<br />

potential.<br />

• Benefits in terms of Construction cost, TBR and N20<br />

shown that sisal fibre reinforcement along with river<br />

19. Impact Of PMGSY <strong>Roads</strong> on Socio-Economic<br />

Aspects and Travel Characteristics – A Case<br />

Study of Tiruchirappalli District<br />

Date of start and duration: 15 th JUlY 2011, 1<br />

year.<br />

Date of completion: 30 th MAY 2012<br />

National Institute Of Technology, Tiruchirappalli<br />

Scope and Objectives<br />

Rural connectivity is a key component of rural<br />

development in India. The Pradhan Mantri Gram<br />

Sadhak Yojana (PMGSY) was launched by the<br />

Government of India to provide rural road connectivity to<br />

the unconnected rural habitations. This study aimed at<br />

assessing the socio-economic and travel characteristic<br />

impact of PMGSY roads through participatory approach.<br />

The objectives of the study were as follows.<br />

•<br />

•<br />

•<br />

•<br />

To assess the overall socio-economic impact on<br />

the lives of the rural people as a result of enhanced<br />

rural connectivity provided through the PMGSY at<br />

the household level and village level.<br />

To assess the impact of the road on the lives of<br />

the villagers in terms of agriculture, employment,<br />

education, health, etc.<br />

To assess the impact of road construction on<br />

financial status and physical capital of the<br />

households.<br />

To assess the impact of road on travel characteristics<br />

of the rural people.<br />

Proposed Methodology (Type of study, Laboratory/<br />

Field)<br />

The methodology used for data analysis is Factor<br />

Analysis, a statistical technique which simplifies a<br />

complex data set by representing the set of variables<br />

in terms of a smaller number of hypothetical variables.<br />

The proposed impact assessment relied primarily on<br />

survey based data collection. The data collection ranged<br />

from traffic density survey to socio economic survey<br />

of households. Within each habitation, 10 randomly<br />

selected households were surveyed using the reflexive<br />

comparison approach. The observed variables were<br />

modelled as linear combination of factors, plus error<br />

ROAD RESEARCH IN INDIA 2011-12 143<br />

terms. Structural Equation Modelling (SEM) was done<br />

to generate a model for the impact study. Analysis of<br />

Moment Structures (AMOS) was used to generate<br />

equation statements to fit the models developed.<br />

Salient-Findings and conclusions<br />

The impact assessment led to the following findings:<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

PMGSY roads have led to an increase in the<br />

income of the households either directly or<br />

indirectly. Improved accessibility and mobility has<br />

ensured better agricultural profit and opened up<br />

new opportunities for employment.<br />

An overall improvement was observed in access to<br />

health facilities especially in case of emergencies.<br />

The reflexive comparison also showed regular<br />

attendance of teachers after connectivity by<br />

PMGSY. Similar trend was also observed in case<br />

of visits by government officials.<br />

Frequency of transport increased by 10 times after<br />

the proper connectivity.<br />

land price increased by 10 times because of the<br />

easy accessibility and subsequent availability of<br />

transport facilities.<br />

The factor analysis extracted four factors. There<br />

appear to be two orthogonal dimensions which<br />

underlie impact of the new connectivity – one<br />

representing lOS of road infrastructure and the<br />

other representing socio economic status of road<br />

user.<br />

City.<br />

Date of start and duration 15 th JUlY 2011, 1<br />

year.<br />

Date of completion 30 th MAY 2012<br />

National Institute Of Technology, Tiruchirappally<br />

Scope and Objectives<br />

The present study aims at finding unsafe bus stops in<br />

Tiruchirappalli city using GIS platform. Bus route from<br />

Thuvakudi to Chathram, Tiruchirappalli city of state<br />

Tamil Nadu has been considered for study. The main<br />

objectives are<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

To identify unsafe bus stop using GIS on a single<br />

bus route in Tiruchirappalli city.<br />

To conduct preliminary survey along the selected<br />

bus route.<br />

To conduct the inventory survey along the selected<br />

bus route.<br />

To identify unsafe bus stops based on number of<br />

pedestrian accidents.<br />

To create logistic regression model, to find the<br />

unsafe bus stop.<br />

To suggest measures to improve the safety of bus<br />

stops in the selected bus route.<br />

Proposed Methodology (Type of study, Laboratory/<br />

Field)<br />

Data were collected and spatial queries were performed<br />

to identify risky bus stops. The tiruchirappalli road<br />

network was obtained from google maps. The location<br />

of bus stop and road intersection were obtained from<br />

the hand held GPS instrument. The attributes such as<br />

the shelter, parking, obstruction and location of bus stop<br />

were obtained from ground survey. The bus route from<br />

Thuvakudi to Chathram was digitised as polyline. The<br />

location of bus stop and road intersection was located<br />

in digitised road network map by Geo referencing. A<br />

buffer zone with a radius of 75 m was created around<br />

each road intersection. The unsafe bus stops were<br />

found using spatial query using ArcGIS.


Salient-Findings and conclusions<br />

The following conclusions were made from the study:<br />

•<br />

•<br />

•<br />

•<br />

Out of the 14 high risk bus stops BHEl boiler and<br />

the Palpannai bus stops are prone to accidents as<br />

they are near to the intersections.<br />

Even though the pedestrian accidents are not high<br />

along the route, facilities should be improved to<br />

overcome the future risk.<br />

Accidents generally occur near the junctions and<br />

intersections. To avoid this sign boards should be<br />

placed.<br />

logistic regression model was created to know<br />

which parameter leads to unsafe bus stops.<br />

The objectives of the study are:<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

To have a preliminary study of the system : toll<br />

collection system<br />

To model the distribution of arrival pattern of the<br />

system<br />

To model the distribution of service time of the<br />

system<br />

To develop a simulation model of the system<br />

To determine the length of influence zone on<br />

upstream of the system<br />

To evaluate the performance of the system and to<br />

determine the users preference on the introduction<br />

of Electronic Toll Collection (ETC)<br />

The study is limited to the toll booth near Akkulam<br />

Bridge, Kazhakuttam- Kovalam NH bypass,<br />

Thiruvananthapuram, Kerala.<br />

ROAD RESEARCH IN INDIA 2011-12 145<br />

Methodology<br />

The toll booth was identified for the study and the<br />

system geometrics were determined. The number of<br />

servers, method of toll collection, whether a barrier is<br />

provided or not, toll collection rate, the peak and off<br />

peak timings at the toll booth were studied.<br />

Video data was collected at peak morning and evening<br />

hours near the toll booth premises to determine the<br />

arrival and service time distribution. Video cameras<br />

were kept at vantage points to record the arrival pattern-<br />

which should be away from the toll booth and service<br />

pattern which should capture the service timings of<br />

vehicle approaching the toll at all the servers.<br />

The video data captured was extracted and the<br />

classified count of vehicle arrival and service time were<br />

determined for every one minute. The distribution of<br />

arrival and service time were determined by checking<br />

for the various available distributions. The number of<br />

arrivals per unit time and the average service time were<br />

determined.<br />

The simulation model of the system was developed<br />

using Queuing ToolPak, version 4, an excel add-in,<br />

based on the arrival and service time distribution and<br />

the average arrival rate and service time. The arrival<br />

rate, service rate, number of servers and queue<br />

capacity were the input data to the model. System<br />

utilization, traffic intensity, average number of vehicles<br />

in the queue and in the system, average time spent<br />

in the queue and in the system, probability of empty,<br />

full and having to wait in the system were obtained as<br />

output.<br />

The output of the simulation model was compared with<br />

that of the data set aside for validation purposes.<br />

The model was used to study the field performance<br />

to optimize the toll booths, the future toll configuration<br />

required for an estimated traffic flow, with change in the<br />

vehicle composition pattern etc. The length of influence<br />

zone of the toll booth for the present condition was<br />

studied and suggestions were given for improving it.<br />

The influence zone length was identified from the<br />

queue length formed from the video data. Optimization<br />

methods were suggested to cope with the future traffic<br />

growth.<br />

The user’s preferences for ETC were collected by<br />

conducting questionnaire survey by sending email<br />

to the travelers using the toll facility. The awareness,<br />

willingness and the rate at which the users were ready<br />

to shift to ETC were determined.<br />

Findings/ Conclusions<br />

The following conclusions were made from the study:<br />

•<br />

From the performance analysis of the system, it is<br />

found that the utilization of the system will hit 100%<br />

in the year 2013


146<br />

• Doubling the number<br />

of servers, re-tracking the<br />

two wheelers and introduction of Electronic Toll<br />

Collection (ETC) is found to<br />

•<br />

•<br />

•<br />

•<br />

•<br />

Drastically reduce the utilization of the system<br />

by 50%, 46% and 63% respectively<br />

Enables the system to run safe till 2021, 2020<br />

and 2026 respectively<br />

Doubling the servers and introduction of ETC<br />

requires change in system configuration; hence<br />

as an immediate solution, re-tracking of the two<br />

wheelers could be implemented from the start of<br />

influence zone to improve the utility<br />

Among the three methods- doubling the servers,<br />

re-tracking of two wheelers and introduction of<br />

ETC, ETC is found to be more effective than the<br />

other two options<br />

From the questionnaire survey, it is found that<br />

the system users have time saving as their main<br />

motive and are willing to shift to ETC, even though<br />

their awareness of ETC is less<br />

The kernel accident density map helped to understand<br />

the spatial distribution of pedestrian accidents in the<br />

Tiruchirappali city.80% of unknown accidents were<br />

happened in NH. Enforcing highway patrol in full swing<br />

and fixing cameras would be helpful to identify the<br />

accused vehicles. The examination of built environment<br />

elements in the hotspot showed that they had lack<br />

of pedestrian infrastructure. Improvement of these<br />

hotspots in terms of modifying the built environment will<br />

make it more pedestrian friendly roadways.<br />

30. Corridor Signal Optimisation under<br />

Heterogeneous Traffic Using Cluster<br />

Analysis<br />

Date of Start: August 2011.<br />

Date of Completion: August 2012.<br />

College of Engineering, Trivandrum (R)<br />

Scope and Objectives<br />

The objectives of this study are:<br />

1. To find the speed, travel time and delay along<br />

the study corridor, thus evaluating the efficiency<br />

of present signal system using GPS SMART<br />

ANTENNATM<br />

2. Determination of most influential cluster using<br />

cluster analysis<br />

3. Determination of ideal offsets from the centroidal<br />

speed of most influential cluster<br />

4. Optimization of the offsets<br />

The scope of the study is restricted to a selected stretch<br />

of corridor consisting of ten signalised intersections in<br />

Thiruvananthapuram city.<br />

Ideal offset determination<br />

Annual offset optimisation<br />

Findings/ Conclusions<br />

Based on the study it may be concluded that<br />

installation of a new signal and retiming of signals<br />

along the corridor has slightly improved the situation.<br />

The present level of service reflects adverse signal<br />

progression and inadequate signal timings along the<br />

corridor. Coordination of signals can further improve the<br />

situation, and hence optimum offsets were arrived at.<br />

Cluster analysis, so far seems to be a realistic solution<br />

to arrive at the cluster speeds for heterogeneous<br />

traffic conditions. From the time space diagram, it<br />

was observed that the delay along the corridor was<br />

reduced by 74% in the up direction down and 84% in<br />

the down direction, when optimum offsets were used.<br />

ROAD RESEARCH IN INDIA 2011-12 149<br />

Thus the objective of minimum delay can be satisfied<br />

using optimum offsets. The optimum offsets obtained in<br />

the study would result in better coordination along the<br />

corridor minimising delay and number of stops. From<br />

the time space diagram it can be observed that, the<br />

efficiency of bandwidth for the up and down directions<br />

were 25 and 29.2% respectively. A bandwidth of 40 to<br />

55% is considered good. Bandwidth is limited because<br />

of the minimum green in the direction of interest. Thus<br />

based on the bandwidth objective, the system needs a<br />

thorough retiming.<br />

Effect of dynamic characteristics of vehicles was<br />

evident from the variation of PCU values.<br />

The increase in proportion of a vehicle type will<br />

certainly increase the level of interaction in the<br />

traffic stream.<br />

The simultaneous equation system automatically<br />

accounts for mutual interaction of vehicles present<br />

in the traffic stream.<br />

The saturation flow model developed can be<br />

used for prediction of flows under identical traffic<br />

Challenged in Rural <strong>Highway</strong>s.<br />

Date of start and duration 15 th JUlY 2011, 1<br />

year.<br />

Date of completion 30 th MAY 2012<br />

National Institute of Technology, Tiruchirappally<br />

Scope and Objectives<br />

The objectives are<br />

•<br />

•<br />

To review guidelines and standards from India and<br />

abroad on pedestrian facilities.<br />

To study the difference in behaviour of different<br />

types of pedestrians.


• To suggest guidelines,<br />

standards and specifications<br />

for the safe path of pedestrians using innovative<br />

techniques.<br />

•<br />

•<br />

To provide guidelines to make it as disabled-friendly<br />

with ramps/ lifts for physically challenged.<br />

To implement inter-disciplinary concepts in<br />

providing lighting and signalization.<br />

Proposed Methodology (Type of study, Laboratory/<br />

Field)<br />

This project deals with the preparation of State of the<br />

Art report on pedestrian facilities. For this, pedestrian<br />

facilities and the guidelines followed in different countries<br />

have been collected. To analyze the crossing behavior<br />

of different types of pedestrians, gap acceptance<br />

behavior of different types of pedestrians was studied.<br />

Pilot survey was conducted in NIT, Tiruchirappalli<br />

Quarters Gate and Electronics Stop along NH-67 to<br />

identify the parameters to be considered. Then video<br />

survey was conducted in BHEl Training Centre and<br />

Ganesha Point considering seven parameters like the<br />

age and gender of pedestrians, walking speed, group<br />

size, gap size, waiting time of the pedestrians and the<br />

type of the approaching vehicle. Binary logit model<br />

was developed to arrive at the probability of accepting a<br />

near or far gap by the pedestrians. Based on the study,<br />

it was found out that pedestrian walking speed, gap<br />

size, age and type of the approaching vehicle should<br />

be considered while selecting a pedestrian facility.<br />

Salient-Findings and conclusions<br />

At NIT, Tiruchirappalli Quarters Gate, the pedestrian<br />

flow is very less and almost all classes of pedestrians<br />

are found there. The 15 th percentile, average and the<br />

85 th percentile walking speeds are 0.9 m/s, 1.1 m/s<br />

and 1.4 m/s. The 15 th percentile, average and the<br />

85 th percentile gap sizes are 10 s, 13s and 14s. At<br />

Electronics Stop, it is mostly the working class using<br />

the facility and their walking speeds are comparatively<br />

higher and the gap acceptance values are less. The<br />

15 th percentile, average and the 85 th percentile walking<br />

speeds are 1.1 m/s, 1.3 m/s and 1.5 m/s. The 15 th<br />

percentile, average and the 85 th percentile gap sizes<br />

are 7 s, 12s and 14 s. At BHEl Training Centre, the<br />

average walking speed was found to be 1.3 m/s.In<br />

BHEl Training Centre, at 10% level of significance<br />

gap and group size were significant and in Ganesha<br />

Point at 10% level of significance walking speed and<br />

age of the pedestrian were significant. Ganesha Point<br />

is a round-about intersection and the BHEl Training<br />

Centre is a four-legged intersection. When the walking<br />

speeds are more, people the probability of accepting a<br />

far gap is more. Similarly, old aged people will accept<br />

ROAD RESEARCH IN INDIA 2011-12 151<br />

far gaps in contrary to young people. When the gap<br />

size is less, people usually go for far gaps and when<br />

the approaching vehicle is one of low PCU, people will<br />

go for far gaps.<br />

33. Development of Fuzzy Logic Based<br />

Performance Evaluation Model for Bus<br />

Transit<br />

Date of Start: August 2011<br />

Date of Completion: August 2012.<br />

College of Engineering, Trivandrum (R)<br />

Scope and Objectives<br />

Public transit is an integral and important component of<br />

local transportation systems. The public transit system<br />

provides a better and safer environment by reducing<br />

congestion, and creating more efficient solution to public<br />

transportation problems. Fuzzy logic is ideally suited<br />

for model development when the exact dynamics of<br />

the system are partly known and understood, but some<br />

vague ideas and expert knowledge are available. Fuzzy<br />

logic can be used effectively in capturing the variability<br />

of the traveller’s appraisal of the different performance<br />

attributes as well as the variability in their perception<br />

to the various attribute levels. The main objective<br />

of this study was to develop a fuzzy logic model for<br />

performance evaluation of the system. This study deals<br />

with the development of rule-based fuzzy logic (RBFl),<br />

commonly used in many traffic and transportation<br />

systems applications. The RBFl uses simple if-then<br />

rules to describe the systems input-output relations.<br />

The objectives of this study are:<br />

•<br />

•<br />

•<br />

•<br />

To identify the factors affecting the performance<br />

of bus transit system and to prioritize these<br />

performance attributes<br />

To analyze the users’ rating of present performance<br />

of bus transit system<br />

To develop a model to estimate the performance<br />

index of bus transit system based on Fuzzy logic<br />

To find out the influence of the performance<br />

attributes on the performance index<br />

The scope of this study is limited to commuters in<br />

Trivandrum city who carry out daily work trips.

36. Congestion Analysis of Heterogeneous Traffic<br />

using GPS-fitted Probe Vehicles<br />

Date of Start and Duration: 01 August 2011, 9<br />

Months<br />

GENERAl REPORT ON<br />

Date of Completion: 01 May 2012<br />

<strong>Indian</strong> Institute of Technology Madras, Chennai<br />

- 600 036<br />

Scope and Objectives<br />

The scope of this project work is limited to analyzing<br />

the influence of vehicle composition, cross roads and<br />

side friction activities on travel times (and congestion<br />

index) through probe vehicles for two selected corridors<br />

in Chennai city. The primary objective of this research<br />

is to analyze travel times and delays in a corridor<br />

using primarily the probe vehicle data, especially for<br />

congested conditions under heterogeneous traffic. The<br />

overall objective is to develop relationships between<br />

travel time/ congestion index and the influencing<br />

factors.<br />

The following lists the specific objectives of the study:<br />

i. To evaluate travel times and delays in the selected<br />

corridors under varying conditions of traffic.<br />

ii. To develop congestion indices for road segments<br />

at different levels of congestion<br />

iii To model the relationship between travel time/<br />

congestion index and the related influencing<br />

factors through regression analysis.<br />

iv. To analyze the travel time characteristics vis-avis<br />

fringe conditions.<br />

Proposed Methodology<br />

Travel time and speed data were collected by using<br />

GPS devices on probe vehicles (two-wheelers, auto<br />

rickshaws and cars). The data on side roads, median<br />

openings and bus-stops without busbays were collected<br />

manually by marking waypoints in the GPS. The data<br />

on side friction was collected by recording the side and<br />

front views using SMARTY which were later analyzed<br />

using PCViewer Software. Analysis of travel times was<br />

done using MACROS and modeling was carried using<br />

SPSS Software.<br />

Salient-Findings and Conclusions<br />

The models provide insights into the variability of travel<br />

times across vehicle types and time periods. The<br />

developed relationships between the two dependent<br />

variables (travel time and congestion index) and the<br />

aforementioned independent variables were generally<br />

logical. The coefficient values and signs were also<br />

logical. The influence of intersections on travel time<br />

was the most significant factor which is evident from<br />

the fact that the variable enters the model in almost all<br />

cases. Further, the model results had improved when<br />

the volume parameter (PCU/ metre of carriageway<br />

width) had been incorporated. The models also explain<br />

the influence the volume on a section of road has on


the individual travel times. It has been shown that side<br />

friction can have effects on performance measures<br />

(travel time, congestion index in this study). This<br />

leads to the recommendation that travel time studies,<br />

particularly in the developing world, can include this<br />

variable. The model that considers the vehicle type<br />

and time period as variables provides insight into<br />

the significance of all the independent variables. The<br />

variations in travel times and congestion index values<br />

by vehicle type are brought out by these models The<br />

ability to utilize the gaps in a congested situation<br />

exhibited by two-wheelers when compared to the other<br />

vehicle types, is highlighted by such models.<br />

recommendations for Dissemination<br />

It is recommended that travel time studies (particularly<br />

developing world) can include this variable. Although<br />

significant results were obtained in modeling travel<br />

times and congestion index from traffic volumes,<br />

roadside friction and other road based parameters,<br />

further work in this area is recommended. The study<br />

is limited only to linearly regressed travel time models.<br />

Other forms of models can be considered for future<br />

work. Also, more cases studies can be considered to<br />

generalize the results.<br />

37. Data Fusion Based Spatial Traffic Parameter<br />

Estimation and Prediction<br />

Date of Completion: 23.04.2012<br />

<strong>Indian</strong> Institute of Technology Madras, Chennai -<br />

Scope and Objectives<br />

The estimation and prediction of traffic parameters<br />

are inevitable in many Intelligent Transportation<br />

Systems (ITS) application such as Advanced Traveler<br />

Information Systems (ATIS). In this study, different<br />

models are proposed to estimate and predict two of<br />

the most important spatial/lagrangian parameters –<br />

density and travel time - that are difficult to measure<br />

from the field. Due to their spatial characteristics, a<br />

single data collection technology cannot measure both<br />

of these parameters simultaneously capturing their<br />

spatial variations. Therefore, a relatively new approach<br />

ROAD RESEARCH IN INDIA 2011-12 155<br />

is explored in this study using data fusion from multiple<br />

sources. The following are the sub-objectives of the<br />

study:<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

Development of models for estimating spatial<br />

parameters based on data fusion approach<br />

Comparison of data fusion model with non-data<br />

fusion or single source model<br />

Validation of data fusion model using field and<br />

simulated data<br />

Sensitivity analysis of the data fusion model using<br />

simulated data<br />

Calibration and validation of simulation software<br />

VISSIM for generating additional data required for<br />

the models<br />

Prediction of density and travel time using time<br />

series analysis<br />

Development and corroboration of models using<br />

simulated data<br />

The models were developed and corroborated using<br />

limited data samples from a small study stretch of<br />

maximum length 1.82 km. For delivering detailed<br />

conclusion, better data sets are required from longer<br />

stretches with varying traffic conditions. The data<br />

fusion model developed used data from two different<br />

sources only. The prediction models were corroborated<br />

using simulated data alone, therefore performance<br />

may vary in real condition. The developed models are<br />

independent of the study stretch characteristics and<br />

can be applied for any stretch of any length.<br />

Proposed Methodology<br />

The following are the different tasks accomplished in<br />

the present study<br />

a) literature review: A detailed literature review<br />

was carried out on different approaches of<br />

estimating and predicting spatial traffic parameters.<br />

Finally, data fusion (using multiple data sources)<br />

approach was adopted for estimation and time<br />

series approach for prediction of parameters.<br />

Data Collection and extraction:<br />

b) The location<br />

data (flow and derived space mean speed) and<br />

spatial data (travel time) were collected using<br />

video cameras and GPS equipped test vehicles<br />

respectively from the selected road stretch in<br />

Chennai. Data were collected on different days<br />

and time for a total of 8.5 hours. Since the field<br />

data collection was laborious, the additional data<br />

required were generated using the simulation<br />

software VISSIM. Before generating the data, the<br />

parameters in VISSIM were calibrated so as to<br />

represent the field conditions.


156<br />

c)<br />

Model Development and Corroboration:<br />

Two models were developed for estimating the<br />

parameters – one using data fusion approach and<br />

the other using data from only one type source.<br />

The data fusion methodology was adopted from<br />

a previous study conducted by Chu, Oh, and<br />

Recker (2005). The data fusion model used<br />

location-specific flow data from video data and<br />

spatial travel time data from GPS to estimate<br />

density. Whereas the single source model<br />

estimated density using the flow and space mean<br />

speed from video data. The density estimation<br />

was carried out using Kalman filter technique.<br />

In both the cases, the average stream travel<br />

time was estimated using this density, based on<br />

fundamental traffic flow relation.<br />

Using the simulated data, time series models were<br />

developed for predicting density and travel time.<br />

The modeling was carried out in a systematic<br />

way following four major steps such as model<br />

identification, selection of model, diagnosis<br />

checking, and validation. The models were<br />

developed in software R in which the parameters<br />

were estimated based on maximum likelihood<br />

approach. The developed models were Seasonal<br />

Auto Regressive Integrated Moving Average<br />

(ARIMA) which were capable of capturing the<br />

seasonality in the data reasonably well.<br />

d) evaluation of Models: The performances of<br />

models were evaluated based on Mean Absolute<br />

Percentage Error (MAPE) and Root Mean Square<br />

Error (RMSE).<br />

Salient-Findings and Conclusions<br />

The following are the major contributions of the study.<br />

Two model based approaches for estimating density<br />

and travel time were discussed and corroborated using<br />

both field and simulated data. From the results it was<br />

observed that the data fusion approach of estimating<br />

parameters performs better than a single source<br />

model. The developed model was physically intuitive<br />

and independent of the data collection technique.<br />

Calibration of VISSIM for the specific location was carried<br />

out before generating required data. These data were<br />

used for sensitivity analysis of the data fusion model<br />

and it showed that the optimum penetration rate for<br />

best density estimate was 4% for the traffic conditions<br />

under consideration. The model performance was<br />

independent of the initial density value assumed for<br />

starting the estimation scheme in Kalman filter.<br />

Models were developed for predicting density and travel<br />

time using time series approach and corroborated using<br />

simulated data. The models captured the seasonal<br />

variations and it was observed that the models were<br />

GENERAl REPORT ON<br />

capable of both short-term and medium-term prediction<br />

with reasonable accuracy. The performance of the<br />

models can be improved if multiple weekdays’ data are<br />

used for developing the model.<br />

College of Engineering, Trivandrum (R)<br />

Scope and Objectives<br />

Intelligent Transportation Systems (ITS) maximise<br />

the capacity of infrastructure, reducing the need to<br />

build additional highway capacity. Advanced traveller<br />

information systems (ATIS) is a subset of intelligent<br />

transportation systems that will be able to provide all<br />

traveller groups the opportunity to minimise trip delays<br />

by delivering accurate on demand real time information<br />

on traffic conditions. Design of ATIS should be based<br />

on information requirements obtained directly from<br />

the end users of the system, to ensure the greatest<br />

chance of influencing their driving behaviour. In a<br />

developing country like India, a properly designed<br />

traveller information system, with the road user in mind<br />

can reduce traffic congestion, improve navigational<br />

performance, decrease the likelihood of an accident,<br />

reduce fuel costs and air pollution and increase driver<br />

efficiency.<br />

The specific objectives of this study are:<br />

a)<br />

b)<br />

c)<br />

To design questionnaire specifically for private<br />

drivers and commercial drivers.<br />

To bring out the information requirements for ATIS<br />

from the targeted road user groups.<br />

To develop mathematical models for predicting<br />

the user preferences and analyze its variation<br />

with respect to demographic and travel patterns<br />

of road users.<br />

Methodology<br />

The population of road users in Thiruvananthapuram<br />

city are classified into private drivers and commercial<br />

drivers. Private motorists include people who commute<br />

to and from work, are business travellers, male and<br />

female drivers over 18 years, who travel for enjoyment<br />

also in both urban and rural settings. Commercial<br />

vehicle drivers are truck drivers and bus drivers are paid<br />

to drive on a regular basis. The survey was conducted<br />

for a sample of 364 private drivers and 250 commercial<br />

drivers. The main aim in the design of the survey was<br />

to bring out the high priority information requirements<br />

of private drivers and commercial drivers for a safe<br />

and efficient travel. Therefore, separate questionnaires<br />

were prepared for the two road user groups. Both the<br />

questionnaires had three main sections on (i) Basic<br />

background information, (ii) Trip characteristics, (iii)<br />

Preferences for ATIS.<br />

Basic background information included questions<br />

regarding gender, age, educational qualification, number<br />

of years of driving experience, etc as it significantly<br />

impacted the route-choice behaviour of the drivers.<br />

Both work trip and recreational trip are considered for<br />

GENERAl REPORT ON<br />

assessing the trip characteristics of drivers. The timings<br />

of to and fro trips, level of congestion experienced<br />

during the trips, percentage use of alternate routes<br />

and reasons for taking alternate routes of both private<br />

and commercial drivers were asked. The drivers<br />

were asked to prioritise the information, which would<br />

assist them to arrive at their destination, in a manner<br />

perceived by the driver as most efficient. In the third<br />

section, respondents were asked for their preference<br />

to use ATIS, prioritise the sections of user services<br />

under ATIS, preferred source of information and time<br />

of information. The feedback from the questionnaire<br />

survey was statistically analyzed and then multinomial<br />

logistic models were developed to predict the user<br />

preferences with respect to the socio economic and<br />

travel characteristics.<br />

Findings/ Conclusions<br />

Though ATIS was a new technology to the road<br />

users, it was accepted by 96.3% of the private drivers<br />

and 99.6% of commercial drivers. It was seen that<br />

information on traffic volume and delay was the most<br />

preferred information for both private and commercial<br />

drivers. Both private and commercial drivers preferred<br />

the section on traffic and road conditions as most<br />

important. Regarding the information delivery units, the<br />

private drivers of Trivandrum city had first preference<br />

for in vehicle units, followed by mobile phones.<br />

Commercial drivers preferred in vehicle units as their<br />

first choice for information delivery units, followed by on<br />

road VMS. Commercial drivers show more preference<br />

to have on road VMS than private drivers, which is the<br />

most suitable form of providing information.<br />

Multinomial logistic regression models are developed<br />

to predict polychotomous dependent variables based<br />

on values of a set of categorical predictor variables.<br />

Here, the user preferences of private and commercial<br />

drivers for advanced traveller information system vary<br />

with respect to their individual socio economic and<br />

travel characteristics. The demographic and travel<br />

characteristics that significantly contributed for the<br />

private driver preferences for ATIS are age, gender,<br />

travel time of trip, mode of transport, familiarity with<br />

residing place, percentage use of alternate routes and<br />

for the commercial driver preferences for ATIS are age,<br />

driving experience, work trip travel time, percentage<br />

use of alternate routes.<br />

The efficiency of a traveller information system for<br />

Trivandrum city can be enhanced by adhering to<br />

these user preferences, so as to influence their travel<br />

behaviour. These trends need to be analyzed regularly,<br />

as technology advances.<br />

40. A Lumped Parameter Model-Based Approach<br />

for Estimation Of Traffic Density<br />

Date of Completion: July 2012<br />

<strong>Indian</strong> Institute of Technology Madras, Chennai<br />

- 600 036<br />

Scope and Objectives<br />

The overall objective of this dissertation was to<br />

develop and implement a model-based scheme for<br />

real-time estimation of traffic density under <strong>Indian</strong><br />

traffic conditions, which will be useful for congestion<br />

management on urban arterials through ITS, using<br />

available information from location based sensors. The<br />

following sub-objectives were pursued to achieve the<br />

overall objective of this study:<br />

•<br />

•<br />

Modification and corroboration of the scheme to<br />

account for certain specific issues associated with<br />

ROAD RESEARCH IN INDIA 2011-12 159<br />

urban arterials in India such as existence of the<br />

non-uniform traffic conditions 0 due to the influence<br />

of traffic signals, un-availability of real time side<br />

road data etc.<br />

The present study corroborates the model based<br />

estimation schemes using data collected from a three<br />

lane urban roadway in the city of Chennai, India.<br />

Only one section at a time is considered here due to<br />

constraints in data collection. Once automated data<br />

collection techniques are available, the methodology<br />

can be extended to estimate density for adjoining<br />

sections simultaneously. The scope of the present<br />

study can be extended to other sections or roadways<br />

if automated flow and speed data are available from<br />

consecutive points in those sections.<br />

Proposed Methodology<br />

The data requirements were identified and data were<br />

collected from the study stretch in Chennai, India using<br />

video recording technique. Data extraction was carried<br />

out manually at every one minute interval. Steady state<br />

speed-flow-density relationships (stream models) were<br />

developed from the collected data. Then a dynamic<br />

macroscopic model was formulated based on the<br />

lumped parameter approach by incorporating the<br />

developed traffic stream models. An estimation scheme<br />

was designed for estimation of traffic density using<br />

the developed dynamic model and extended Kalman<br />

filtering technique (EKF). The developed scheme was<br />

implemented and corroborated using data collected<br />

from sections along the study stretch. The proposed<br />

scheme was later modified to address certain issues<br />

specific to urban arterials in India.<br />

Salient-Findings and Conclusions<br />

Real-time estimation of traffic density is essential for<br />

congestion mitigation applications using ITS. Such<br />

applications for urban arterials in India, which are not<br />

yet equipped with automatic traffic sensors, is an area<br />

almost untouched by most of the researchers due to<br />

limitation in data availability. Hence, methods which are<br />

less demanding in terms of data need to be explored. In<br />

recognition of this need, a simple yet efficient method<br />

of estimating density with minimal data requirement<br />

was presented in this study. This study resulted in a<br />

number of conclusions as listed below:<br />

•<br />

•<br />

The presented model represented an advancement<br />

of the state-of-the-art in macroscopic modeling<br />

of heterogeneous traffic in India and application<br />

of such models in real-time estimation of traffic<br />

density/congestion.<br />

Since there were no exhaustive traffic stream<br />

models developed for the heterogeneous traffic<br />

conditions in India, the developed stream models is


160<br />

•<br />

•<br />

•<br />

•<br />

a valuable contribution towards many applications<br />

in planning, design and effective management of<br />

road systems in India.<br />

The non-continuum dynamic macroscopic model<br />

proposed in this research based on the lumped<br />

parameter approach overcame many limitations<br />

in modeling traffic using microscopic or continuum<br />

approach.<br />

It was found that converting heterogeneous traffic<br />

into a homogeneous equivalent using constant<br />

values of PCU is a good enough representation<br />

in the proposed non-continuum macroscopic<br />

modeling approach, compared to the approaches<br />

of dynamic values of equivalents or explicitly<br />

including the different categories of vehicles in the<br />

model.<br />

The model based scheme based on Kalman filter<br />

is proved to be an adequate tool for the estimation<br />

of traffic density in real-time, making it useful for<br />

congestion analysis through ITS in India.<br />

This research is one of the first exhaustive studies<br />

in the area of real-time estimation of traffic density<br />

under <strong>Indian</strong> traffic conditions and will be useful for<br />

the real time implementation of ITS applications<br />

under <strong>Indian</strong> conditions.<br />

years<br />

Date of Completion: October 2012<br />

<strong>Indian</strong> Institute of Technology Madras, Chennai -<br />

600 036<br />

Scope and Objectives<br />

The following specific objectives have been derived<br />

1) To collect and analyze location based and spatial<br />

traffic data under heterogeneous conditions.<br />

2) To predict spatial traffic parameters such as<br />

travel time, and density using location based<br />

data using a macroscopic traffic flow model for<br />

ITS applications.<br />

3) To predict the travel time and arrival time of public<br />

transit vehicles using data driven and model<br />

based approaches and to validate the same.<br />

GENERAl REPORT ON<br />

4) To develop a model to predict the travel time of<br />

other personal vehicles using the predicted bus<br />

travel time from GPS fitted public transit vehicles<br />

and to validate the same.<br />

5) To quantify congestion under heterogeneous<br />

traffic conditions using the GPS data from public<br />

transit vehicles and to validate the same.<br />

The focus of second objective is to use location based<br />

data alone to predict stream travel time whereas, the<br />

third, fourth and fifth objective aims to use GPS data<br />

from public transit vehicles to predict stream travel<br />

time and quantify congestion. The scope of the present<br />

thesis work is restricted to urban arterials under<br />

heterogeneous traffic conditions. Also, the congestion<br />

quantification will be based on travel time based<br />

measures.<br />

Proposed Methodology<br />

The second objective of predicting spatial traffic<br />

parameters such as travel time, and density using<br />

location based data involve the videotaping of the traffic<br />

conditions at selected study route to get the required<br />

data on flow, density and travel time. The lighthill-<br />

Whitham-Richards (lWR) macroscopic traffic flow model<br />

discretized in both space and time was employed in<br />

the estimation scheme. The resulting partial differential<br />

equations were solved numerically using the ‘forward–<br />

time backward–space’ finite difference formulation.<br />

Both linear and exponential speed-density relations<br />

were considered and incorporated into the macroscopic<br />

model. The estimated density was corroborated with the<br />

density obtained from input-output analysis. The travel<br />

time estimates were compared with both manually<br />

observed travel times and travel time from GPS fitted<br />

probe vehicles. The time series model based on Box-<br />

Jenkins Seasonal ARIMA was developed to predict the<br />

flow values, which will serve as the input for the lWR<br />

macroscopic model.<br />

The third objective of predicting bus travel time and<br />

arrival time involves the automatic vehicle location<br />

(AVl) data of seven public transit buses reporting every<br />

5 sec. from 8 AM to 8 PM using permanently fixed GPS<br />

units over a period of 3 months in route number 5C<br />

connecting Parrys bus depot in the northern part of<br />

Chennai, and the Taramani bus depot in the southern<br />

part of Chennai city. Before developing the bus arrival<br />

time prediction model using data driven and model<br />

based approaches, the first step is the identification<br />

of suitable input data by analyzing trip-wise, daily<br />

and weekly pattern of bus travel time through valid<br />

statistical tests. It is then followed by the development<br />

of accurate bus arrival prediction model using time<br />

series techniques like multiplicative decomposition,<br />

exponential smoothing and exponential smoothing<br />

combined with Kalman filtering technique (KFT).


To satisfy the fourth objective of predicting travel time<br />

of other personal vehicles in the stream using only the<br />

bus travel time, two approaches have been proposed:<br />

one based on the ratio of the section travel times of<br />

public transit to other vehicles and other one based on<br />

the quantifiable relationship between the public transit<br />

and other vehicles section travel times. As the dwell<br />

time at bus stops is a unique characteristic of transit<br />

buses when compared to other vehicles in the stream,<br />

a methodology has been proposed to find the dwell<br />

times based on the approaching and departing speeds<br />

at bus stops.<br />

The final phase of the work is to quantify congestion<br />

by using only the public transit buses as probes. The<br />

congestion index (CI), one of the simple and most widely<br />

used measures to quantify congestion is considered.<br />

The three independent variables considered are bus<br />

CI after removing the dwell time and interpolating the<br />

travel time for the removed portion, lane width and<br />

the presence or absence of a signalized intersection<br />

as a dummy variable. The dependent variable is the<br />

personal vehicle(s) CI. Since there are no bus bays for<br />

buses to stop at bus stops in most part of the urban<br />

roads in India, sometimes there are chances that, during<br />

peak hours, this stopping behavior of buses at bus<br />

stops could cause congestion behind. Hence the dwell<br />

times at bus stops were considered as an additional<br />

independent variable to study its effect on congestion.<br />

In this case, the four independent variables considered<br />

are bus C.I calculated using actual bus travel times<br />

after removing dwell times, dwell time, lane width and<br />

presence/absence of intersection. Regression models<br />

were developed separately for off-peak period, peak<br />

morning and peak evening period while treating three<br />

different modes, namely two-wheeler, auto and car as<br />

categorical variables. Similarly mode-wise regression<br />

models were developed treating off-peak, peak morning<br />

and peak evening period as categorical variables.<br />

Regression model considering all the modes and all<br />

the periods was also developed for three independent<br />

variables case and four independent variables case for<br />

both constant and variable free flow travel time. The<br />

statistical significance of the independent variables<br />

was assessed before validation. The validation involves<br />

the data splitting approach of randomly selecting 75%<br />

of the samples for model development and using the<br />

remaining 25% of samples for validation by comparing<br />

the observed congestion index with the predicted<br />

congestion index of personal vehicles.<br />

Salient-Findings and Conclusions<br />

The travel time and density estimates based on the<br />

exponential speed-density relation are better to that of<br />

the linear speed-density relation. The developed model<br />

requires only the limited location based data to provide<br />

a complete set of spatial parameters such as density<br />

ROAD RESEARCH IN INDIA 2011-12 161<br />

and travel time estimates along the study route. This will<br />

make it possible to estimate these spatial parameters<br />

from limited point based data. Thus, it ultimately be<br />

helpful for the cost effective implementation of ATIS/<br />

ATMS applications under heterogeneous traffic<br />

environment like India with limited automated data<br />

sources. Also, the input flow data for the macroscopic<br />

model can be predicted well in advance using Seasonal<br />

ARIMA models.<br />

The analysis of bus travel time pattern reveals that, the<br />

previous two weeks’ same-day same-time trips and<br />

previous three trips of the same day are most significant<br />

for predicting the next bus arrival time. The results<br />

show that, using significant trips as input, exponential<br />

smoothing combined with KFT shows better performance<br />

when compared to exponential smoothing. In 100 out<br />

of 105 trips, exponential smoothing combined with KFT<br />

method shows lesser MAPE when compared to simple<br />

exponential smoothing alone. The results of bus arrival<br />

time prediction shows that, both the methods was<br />

reasonably able to predict well the bus arrival time with<br />

77% of the times the prediction error within the user<br />

acceptable range of ± 5 minutes and 50% of the times<br />

the deviation within ± 2 minutes. The results show that,<br />

with constraints such as limited data base, technical<br />

understanding, transferability etc., the classical time<br />

series methods such as exponential smoothing may be<br />

considered for real time Advanced Public Transportation<br />

System (APTS) implementations.<br />

The results of stream travel time prediction indicates<br />

that, the second approach based on relationship<br />

between the bus and other vehicles section travel times<br />

performs better when compared to the first approach<br />

which is based on the ratio of the section travel times of<br />

public transit to other vehicles. Also, 95% of the times<br />

the deviation is within ± 4 minutes; 90% of the times, the<br />

deviation is within ± 3 minutes; 76% of the times, within<br />

± 2 minutes and 42% of the times the deviation within<br />

± 1 minute. This clearly shows that, the approach-2<br />

performs better than approach-1 in estimating the other<br />

vehicles travel times.<br />

The four independent variable case for predicting<br />

the personal vehicle C.I shows comparatively better<br />

R-square values when compared to three variables<br />

case. The basic difference between the two cases is<br />

that, in the former one, the dwell time at bus stops with<br />

associated acceleration and deceleration times is treated<br />

as an additional independent variable. It is interesting<br />

to see that, two-wheeler exhibits a low R-square value<br />

when compared to auto and car, and auto exhibits a<br />

low R-square value when compared to car. The two<br />

wheeler being the smallest mode in the stream with<br />

maximum different characteristics from bus, it shows a<br />

relatively less R-square value when compared to auto<br />

and car. lane width exhibits a negative coefficient in all<br />

the cases considered. It is logical that, when lane width


162<br />

reduces, the capacity gets reduced and may result in<br />

an increased travel time and congestion. Intersection<br />

presence/absence (a binary variable which takes the<br />

value of 1 or 0) exhibits a positive regression coefficient<br />

in all the 7 cases considered. It is reasonable that, when<br />

there is a signalized intersection (the value is 1) in a<br />

500m section, the chances of congestion is high due<br />

to signal delays. Based on the scatter plots between<br />

section-wise bus C.I and other vehicles C.I during<br />

off-peak, morning peak and evening peak period, it is<br />

found that, during congestion in peak hours, vehicles<br />

of different categories exhibit different movement types<br />

when compared to bus, for example, two-wheelers and<br />

auto’s can traverse in the available space as the vehicle<br />

size permits them but it is not so with the passenger<br />

cars. The validation involves the data splitting approach<br />

of randomly selecting 75% of the samples for model<br />

development and using the remaining 25% of samples<br />

for validation by comparing the observed congestion<br />

index with the predicted congestion index of personal<br />

vehicles. The process of random selection was made<br />

three different times with different proportions of<br />

samples for model development and validation and the<br />

developed models were assessed for its accuracy. The<br />

results are encouraging and the proposed approach of<br />

predicting other vehicles C.I using only bus C.I along<br />

with the other roadway information such as lane width<br />

and intersection presence/absence could be considered<br />

for real-time display of congestion levels for Advanced<br />

Traveler Information System (AITS) applications.<br />

42. Microsimulation Study of the Effect of<br />

Vulnerable Road Users on Traffic Flow<br />

Characteristics.<br />

Date of start and duration 15 th JUlY 2011, 1<br />

year.<br />

Date of completion 30 th MAY 2012<br />

National Institute of Technology, Tiruchirappally<br />

Scope and Objectives<br />

By keeping in mind the problem in the city, the objectives<br />

are as listed below:<br />

•<br />

To develop a simulation model for an urban road<br />

section.<br />

GENERAl REPORT ON<br />

•<br />

•<br />

To analyse the effect of vulnerable road users in<br />

base case and horizon year traffic performance.<br />

To find out the major problems associated with the<br />

section and search for the alternatives.<br />

Proposed Methodology (Type of study,Laboratory/<br />

Field)<br />

Multirun simulation is carried out with different<br />

composition and volume of the traffic, which provides<br />

the base year and horizon year traffic performance<br />

considering the mean speed and delay of the study<br />

area. Ultimately, it serves for planning and monitoring<br />

of transportation system.<br />

Salient-Findings and conclusions<br />

The following conclusions were made from the study:<br />

•<br />

•<br />

Increase and decrease in MTWs only have less<br />

effect in overall stream speed compare with all the<br />

categories of vehicles due to their accelerating/<br />

decelerating characteristics even in the minimum<br />

lateral clearances and possibility of over taking on<br />

the same day.<br />

The average delay per vehicle (with larger<br />

dimension) increases rapidly with the increase of<br />

all categories of vehicles compared with increase of<br />

MTWs only. The reason behind this is, vehicle with<br />

larger dimensions are having less speed, occupies<br />

the more area on road, and less accelerating/<br />

decelerating rate.<br />

43. Road Safety with Emphasis on <strong>No</strong>n-Motorized<br />

Traffic<br />

Date of start and duration 15 th JUlY 2011, 1<br />

year.<br />

Date of completion 30 th MAY 2012<br />

National Institute Of Technology, Tiruchirappalli<br />

Scope and Objectives<br />

<strong>No</strong>n-motorized transport has been identified as a priority<br />

area at National, Provincial and local Government<br />

levels and has the potential to become a feasible and<br />

sustainable transport mode. <strong>No</strong>n-motorized transport<br />

along with public transport has a significant role to play<br />

in providing a sustainable alternative to the private<br />

motor vehicle, in reducing overall carbon emissions,


improving air quality and reducing congestion. A design<br />

guide is hence essential to make the non-motorized<br />

travel safe and convenient and also to encourage the<br />

use of non-motorized transport.<br />

The objectives of this project are as follows:<br />

•<br />

•<br />

•<br />

•<br />

•<br />

To review the literature on NMT and the guidelines<br />

and specifications for their safe movement on<br />

highways.<br />

To suggest measures for the safe movement of<br />

NMT like traffic calming, street-scape improvement,<br />

vehicle restrictions and road space reallocation.<br />

To suggest measures to reduce the number of<br />

fatalities of vulnerable non-motorized road users<br />

along high speed corridors.<br />

To analyse the various behaviour of NMT and<br />

suggest measures for the safe crossing of NMT at<br />

intersections along highways.<br />

To suggest guidelines and specifications.<br />

Proposed Methodology (Type of study, Laboratory/<br />

Field)<br />

An extensive review of the bicycle safety literature<br />

associated with bicycle hazards, counter measures,<br />

evaluation criteria and prioritization methods was<br />

conducted. In addition to studies conducted by various<br />

state departments of transportation, FHWA, universities<br />

and research institutes, international efforts in bicycle<br />

and pedestrian safety were reviewed. At the end of the<br />

review, general design parameters for separate cycle<br />

lanes and methods for reducing speed of motorized<br />

vehicles were formulated. The gap acceptance and<br />

yielding behaviour of motorists were also studied<br />

at three different locations along a rural National<br />

<strong>Highway</strong>.<br />

Salient-Findings and conclusions<br />

•<br />

•<br />

•<br />

•<br />

In <strong>Indian</strong> <strong>Highway</strong>s the facilities provided for<br />

non-motorized transport is negligible. New and<br />

innovative measures have to be taken for the safety<br />

of non-motorized road users.<br />

The provision of dedicated cycle lanes encourages<br />

cycling and improves road safety even in cities that<br />

did not have high cycling mode shares.<br />

Where separation of different road users is not<br />

possible, ensuring safe conditions for the integrated<br />

use of the shared road space is necessary to<br />

reduce potential conflict.<br />

By analysing the crossing speed of the bicyclists at<br />

three different intersections, the speed distribution<br />

corresponds to normal distribution. The natural log<br />

normal distribution was found to provide a close<br />

ROAD RESEARCH IN INDIA 2011-12 163<br />

•<br />

•<br />

approximation to the distribution of accepted and<br />

rejected gaps by bicyclists. The crossing speed<br />

values are found to be less and critical gap values<br />

are high in rural highways than in sub-urban<br />

highways. This may be due to the high speed of<br />

vehicles along the rural highways.<br />

The yielding percentage varies from 2 to 5% in rural<br />

highways and 12% in sub-urban highways. Hence<br />

in rural highways yielding signs must be made a<br />

must.<br />

Based on inter-disciplinary approach, it has been<br />

suggested to provide a 3 m wide pathway for<br />

bicyclists. Helical type over bridge crossings is also<br />

suggested.<br />

44. Analysis of Road Accidents Based on Accident<br />

Severity Index (ASI) Method and GIS: A Case<br />

Study of Trivandrum City<br />

Date of Start: August 2010.<br />

Date of Completion: August 2011.<br />

College of Engineering, Trivandrum (R)<br />

Scope and Objectives<br />

Accident analysis studies aim at the identification of<br />

high rate accident locations and safety deficient areas.<br />

Usually, the cause of an accident may not be a single<br />

factor. The combination of a set of factors may lead<br />

to an accident. The major contributors to the accident<br />

are population, vehicle ownership, physical features of<br />

the road, speed of vehicle, traffic volume of the road<br />

etc. The Accident Severity Index (ASI) method is used<br />

to identify the most severe road stretches by giving<br />

weightage points to accidents. The Geographical<br />

Information System (GIS) can be used to edit, analyze,<br />

and display geographical information stored in a spatial<br />

data base. Hazardous locations on highway can easily<br />

be identified by using GIS. In this study, an effort<br />

has been taken to identify the accident prone zones<br />

within Trivandrum City, Kerala using GIS and Accident<br />

Severity Index (ASI) method.<br />

The present study was undertaken with the following<br />

objectives:<br />

•<br />

To prioritize the road stretches using Accident<br />

Findings/Conclusions<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

Percentage of grievous injury occurrence is higher<br />

in Trivandrum city (56%) as well as in the accident<br />

prone stretch, Killipalam – Pappanamcode (63%).<br />

The proportion of state highway in Trivandrum city<br />

is only 3 %. The large area of Trivandrum city is<br />

connected with the other roads (80%). So most of<br />

the accidents are occurring in other roads, and it<br />

is 76%. Because of the lower proportion of state<br />

highway in Trivandrum city, the percentage of<br />

accident occurrence is also lower (1%). In NH the<br />

accident rate is 23%.<br />

Accident distribution based on vehicle type shows<br />

that the accident due to heavy vehicle, light<br />

commercial vehicle, 3- wheeler, 4-wheeler, and<br />

2-wheeler is 12%, 4%, 18%, 51% respectively in<br />

Trivandrum city. The accidents due to two wheelers<br />

are higher in the Killipalam- Pappanamcod road<br />

stretch (41%). The pedestrian accidents were also<br />

higher in that area (21%).<br />

Accident caused due to males and females is 81%<br />

and 19% in the Trivandrum city.<br />

More than 70% of the accidents occurred during<br />

day time.<br />

Most of the accidents caused due to the fault of<br />

driver (75%).<br />

45. Studies on Safety Performance of Two-Lane<br />

Rural <strong>Highway</strong>s Under Mixed Traffic<br />

Date of Completion: June 2012<br />

GENERAl REPORT ON<br />

<strong>Indian</strong> Institute of Technology Madras, Chennai -<br />

600 036<br />

Scope and Objectives<br />

The objective of the present study is to develop a<br />

methodology for safety evaluation of <strong>Indian</strong> highways.<br />

The specific tasks identified to achieve this objective<br />

are:<br />

1. To collect road accident, traffic and road<br />

characteristics data, which could be used to<br />

develop APMs for two-lane undivided rural<br />

highways in India.<br />

2. To identify the various explanatory variables,<br />

which significantly influence the occurrence of<br />

accidents on <strong>Indian</strong> highways.<br />

3. To develop APMs for <strong>Indian</strong> highways, through<br />

statistical modelling with the data collected in the<br />

study.<br />

4. To develop a methodology for the safety evaluation<br />

of <strong>Indian</strong> highways, by reducing the APMs to<br />

simpler forms of base models and multiplication<br />

factors, which can be easily employed by road<br />

safety engineers.<br />

The scope of the present study is limited to <strong>Indian</strong> rural<br />

highways, which have undivided two-lane carriageway.<br />

The study considers only those highways, which run<br />

through plain to rolling terrain.<br />

Proposed Methodology<br />

Data collection<br />

The study stretches for data collection were selected<br />

in such a way that maximum possible variations in the<br />

study variables were captured. Over 200 kilometres of<br />

two-lane undivided rural highways in the state of Tamil<br />

Nadu were selected based on this criterion. Road<br />

accident data for three years period were compiled<br />

from police records. Traffic, road geometric and road<br />

environment data were collected through field surveys.<br />

The data, which were recorded for 200 m sub-sections of<br />

the highway stretches, were compiled to form the base<br />

data, giving the number of accidents and corresponding<br />

explanatory variables in each 200 m sub-section, for<br />

three years. <strong>Highway</strong> geometry, which was recorded<br />

using vehicle-mounted GPS, was processed in CAD<br />

and splines were fitted on to the raw data to calculate<br />

radius of curvature of horizontal alignment and gradient<br />

of vertical alignment.<br />

Modeling Approach<br />

The number of road accidents in a given period (or the<br />

frequency of road accidents) can be expected to follow<br />

a discrete probability distribution, such as Poisson<br />

distribution. To select the best model specification for


development of APMs, models were developed for total<br />

accidents in one year and the performance of the five<br />

specifications were compared. Poisson, NB and Poisson<br />

log-normal models are fixed coefficient models, which<br />

assume that the effect of variables remain the same<br />

across all observations. These models were estimated<br />

by maximising the log-likelihood functions (MlE<br />

technique). The random effects Poisson model allows<br />

the error term to vary across corridors and the random<br />

coefficients Poisson model assumes that the effect<br />

of variables vary across observations. The random<br />

effects and the random coefficients models account for<br />

heterogeneity in data across sites/observations. The<br />

random coefficient models result in a likelihood function<br />

which does not have a closed form solution. These<br />

models were estimated through simulation assisted<br />

maximum likelihood estimation (Sll).<br />

Salient-Findings and Conclusions<br />

1. Accident prediction models (APM) were<br />

developed in the present study for two lane<br />

undivided rural highways in India, which operate<br />

under mixed traffic conditions. Road accident,<br />

traffic, road geometric and road environment<br />

data were collected for a representative sample<br />

of two-lane undivided rural highways and APMs<br />

were developed based on this data, through<br />

count data regression modelling.<br />

2. Poisson, Poisson-gamma (negative binomial),<br />

Poisson log-normal, Poisson model with<br />

random effects and Poisson model with random<br />

coefficients were considered to develop the<br />

APMs. A comparison of the model performance<br />

was carried out and Poisson model with random<br />

coefficients was selected as the best model<br />

specification to develop APMs.<br />

3. Many of the explanatory variables were found<br />

to have random coefficients in the APMs,<br />

suggesting that the effect of these variables on<br />

accidents vary across observations/sites. Based<br />

on the parameter estimates for the distribution<br />

of these random coefficients, 95% prediction<br />

intervals were developed, which could be used<br />

to assess the possible variation in the effect of<br />

these explanatory variables on road accidents.<br />

4. APMs were developed for predicting single-vehicle<br />

and multi-vehicle accidents on two-lane undivided<br />

rural highways in India. length of highway<br />

segment, average daily traffic, the percentage<br />

of motorised two-wheelers, the percentage of<br />

heavy goods vehicles, distance to off-shoulder<br />

hazards, number of driveways per km, width of<br />

carriageway, number of horizontal curves per km,<br />

horizontal curvature, number of vertical curves<br />

per km, gradient, number of curves per km with<br />

sight distance deficiency, the percentage length<br />

of highway with traffic signs and the percentage<br />

ROAD RESEARCH IN INDIA 2011-12 165<br />

length of highway with road markings were found<br />

to be the statistically significant explanatory<br />

variables in these APMs.<br />

5. The APMs developed in the study were reduced<br />

to simpler base models with minimal data<br />

requirement, for practical application under limited<br />

availability of data. Accident modification factors<br />

(AMF), which are multiplicative factors, were<br />

developed to improve the base model prediction<br />

for the effect of variation in the explanatory<br />

variables. 95% prediction intervals were<br />

developed for the AMFs, which could be used<br />

to assess the possible variation in the effect of<br />

these explanatory variables on road accidents.<br />

6. Accident severity prediction model was developed<br />

for the total predicted accidents. The model gives<br />

the thresholds for classification of road accidents<br />

into “no injury”, “minor injury”, “grievous injury”<br />

and “fatal” severity. the percentage of motorised<br />

two-wheelers, the percentage of heavy goods<br />

vehicles, the percentage of non-motorised<br />

traffic, distance to off-shoulder hazards, number<br />

of driveways per km, number of accesses per<br />

km, width of paved shoulder, width of unpaved<br />

shoulder, number of horizontal curves, gradient<br />

and the percentage length of road with markings<br />

were found to be the significant explanatory<br />

variables in predicting accident severity.<br />

7. The APMs developed in the present study,<br />

together with the AMFs and accident severity<br />

prediction model, provides a methodology for the<br />

safety evaluation of two-lane undivided highway<br />

in India. The models can be used to predict the<br />

expected number of road accidents on two-lane<br />

undivided highway, by collision type and severity.<br />

The findings from the present study will also help<br />

in arriving at engineering measures to improve<br />

road safety on these highways.<br />

Concentration<br />

Date of Start: July 2010.<br />

Date of Completion: July 2011.<br />

College of Engineering, Trivandrum (R)<br />

Scope and Objectives<br />

Vehicles are now becoming the main source of air<br />

pollution in urban India. Vehicle emission has become<br />

a focus for environmental studies worldwide. The<br />

traffic environmental impact has then become a major


166<br />

concern of policy makers in both developed and<br />

developing countries. To control and alleviate the traffic<br />

environmental impact, policies related to transportation<br />

demand control and environmental protection have<br />

been implemented in various countries. The pollutant<br />

concentration levels are an important indicator of the<br />

effects of these policies. The estimates of the pollutant<br />

concentration near road intersections are the focus of<br />

air pollution regulations. A properly validated line source<br />

model plays an important role in providing information<br />

for better and more efficient air quality management<br />

planning through simulation of the dispersion of<br />

vehicular pollutants near roads. Transportation systems<br />

contribute significantly to carbon monoxide (CO),<br />

nitrogen oxides (NOx), particulate matter (PM), and<br />

hydrocarbon (HC) emissions in urban areas. Nitrogen<br />

oxides collectively known as NOx and include nitrogen<br />

monoxide (NO) and nitrogen dioxide (NO 2 ). The study<br />

is focussing on the following objectives.<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

To predict Carbon monoxide, Nitrogen dioxide,<br />

Respirable suspended particulate matter and<br />

Sulphur dioxide concentration near an intersection<br />

in East Fort and in Vithura of Trivandrum district<br />

using CAlINE4.<br />

To compare the observed values with National<br />

Ambient Air Quality Standards proposed by Central<br />

Pollution Control Board.<br />

To find the possible relationship between<br />

pollutant concentration, traffic and meteorological<br />

parameters by a model.<br />

To evaluate the prediction accuracy of CAlINE4<br />

and the Regression model for all pollutants by<br />

comparing with observed data.<br />

To predict CO concentration with HYROAD and to<br />

compare with CAlINE4, regression model and with<br />

observed data.<br />

To evaluate CAlINE4, HYROAD and the<br />

Regression model based on statistical performance<br />

measures.<br />

Methodology<br />

•<br />

•<br />

•<br />

CAlINE 4 (California line Source) was chosen<br />

to predict roadside Carbon monoxide, Nitrogen<br />

dioxide, Respirable suspended particulate matter<br />

and Sulphur dioxide concentration near an<br />

intersection at single links in Eastfort and Vithura.<br />

The observed ambient pollutant concentration was<br />

compared with limit prescribed by National Ambient<br />

Air Quality Standards.<br />

Regression model was formed for the pollutants,<br />

with observed pollutant concentration as dependent<br />

variable and observed traffic volume, wind speed,<br />

wind direction and temperature as independent<br />

variables using SPSS.<br />

GENERAl REPORT ON<br />

• Finally, the prediction accuracy of CAlINE4,<br />

HYROAD and the regression model was evaluated<br />

by comparing with observed data and using<br />

statistical performance measures.<br />

Findings/ Conclusions<br />

•<br />

CAlINE 4 predictions showed that in Eastfort<br />

CO was overpredicted by 11% and NO was 2<br />

overpredicted by 90%.<br />

• In Vithura CO was underpredicted by 40% and NO2<br />

was overpredicted by 81%.<br />

• In both locations, RSPM and SO2<br />

were<br />

underpredicted.<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

•<br />

In CBD area, two wheelers contributed 31%, three<br />

wheelers 27%, four wheelers 25% and bus 17 %<br />

of CO.<br />

In rural area two wheelers contributed 41%, 3W<br />

23%, 4W 23%, and truck 14 % of CO.<br />

Comparing observed values with NAAQS, only<br />

RSPM in Eastfort (116 μg/m3) is exceeding the limit<br />

prescribed (80 μg/m3 ) by 31%.<br />

Regression model performed better than CAlINE4<br />

in case of all pollutants.<br />

HYROAD gave slight over prediction of CO by<br />

4.5%.<br />

Prediction accuracy of CAlINE4 was found to be<br />

64%, 44%, 46%, & 44.3% for CO, NO , SO , &<br />

2 2<br />

RSPM respectively.<br />

Overall prediction accuracy of CAlINE4 and<br />

Regression model for all pollutants was found to<br />

be 49.6% & 83.6% respectively.<br />

For CO prediction, HYROAD showed 80.8% of<br />

accuracy, Regression model, 79.6% and CAlINE4,<br />

64%.<br />

HYROAD and Regression model was found to<br />

be more preferred models for CO prediction than<br />

CAlINE4.<br />
