PART IV: Summary of Comments17-May-10Reviewer Comments Distribution of Ratings■ The cost is reasonable and the products appear to be far-reaching and readily accessible. This looks like a goodinvestment and efficient means to deploy performance information.■ This project is directly related to G05, and involves the development of a safety data portal or clearinghouse. TheStrategic Highway Research Program's Naturalistic Driver Study will produce new information relating to the researchobjectives of G05 and G07, specifically in the areas of outreach and research, which may aid in the future implementationof the National SHSP. It may be useful to wait for SHRP2 results. SHRP2 data will make for a valuable new link toSHSP portal(s) in the future.■ It's time to stop planning to plan and creating documents that end up sitting on the shelf, and starting acting to resolve theproblem. $200K would be better spent elsewhere. Research that supports the SHSP but I believe there is a need in thedissemenation of safety material to the road user.Item #66:E-05Design Methods for Laterally Loaded Piles and PileGroups near Mechanically Stabilized Earth Walls(17)(46)NR 0 1 2 3 4 5SCOR 2 2 7 5 1RAC 2 4 5 7 14 13 4Standing Committee on Research■ This research topic should be put on hold until the results of an ongoing study titled 'Interaction of Integral AbutmentPiling and MSE Walls' are analyzed. The Principal Investigator is Prof. George Filz of Virginia Tech. Final report is duein August 2010.■ need but lower priority■ [Rating: 2] The reviewer is not aware any real concerns or problems of laterally loaded pipes near MSE walls.Research Advisory Committee■ Use of these systems will grow in the future. Also this is a safety issue. Appropriate design is a critical need.■ Potential benefit for shorter stuctures.■ This subject needs to be further investigated and design guidelines developed.■ This Department does not build these types of structures. I have not heard of this being a concern; however, the use ofthis type of structure is not too common in the region. Those in the region may be using structure types (integrals or verysmall cap/bent type abutments) where the lateral demand/resistance is not critical.■ This is relevant, necessary research where integral abutments routinely used. Not currently a nationwide problem.Other■ Related to R02 but R02 is much braoder and is looking at several technologies (40+)Item #67:G-23Advanced Work Zone Traffic Control Using Real Time-Travel Time Data(17)(46)NR 0 1 2 3 4 5SCOR 1 3 1 7 4 1RAC 1 2 7 3 21 11 4Standing Committee on Research■ This project is tied way too closely with one particular technology, the Bluetooth SBIR that FHWA is working on. Thereare many variations of this same basic technology that could be deployed to the same effect. The budget seems to bevery high unless there will be the purchase or rental of a number of work zone ITS devices for the study. The basicconcept of the project is good, but needs to be made more technology neutral in terms of how the travel times aregenerated.■ Problem statement says quite a bit about real time data acquisition, little about how data would be appliedIV-46
PART IV: Summary of Comments17-May-10Reviewer Comments Distribution of Ratings■ The collection of Bluetooth data is supported however, the boundary between DOT SBIR (proprietary) and this NCHRPwork has to be clarified. It may be better to postpone this project until the commercial product resulted from SBIR is fullyavailable and operationable.■ Work will be almost entirely duplicative of projects under way. See attached comments.■ [Rating: 3] Recommend to reduce the scope and focus more on the algorithm development and simulation analysis priorto pushing for field testing of the Bluetooth technology developed in the SBIR project). Recommend reducing thefunding, in line with reducing the scope of work. Suggested funding: $450,000Research Advisory Committee■ The time frame for research is too long. 18 months would be more appropriate. There are other technologies that can beused. We also believe this technology is several years away and therefore not appropriate to study at this time.■ Providing real time travel information to drivers is already being used in traffic management plans for work zones and isan effective tool and resource for them to make decisions on their route selection.■ The transportation industry would be interested in this type of information as a way to cut down on unnecessary timestanding still in traffic back-ups. NCHRP should spearhead the effort creating standards for the industry. Similar effortswith a slightly different focus are taking place applying mobile phone and GPS technology. There is a high probabilitythat this research will be successful because of the existing technology that can be used. The anticipated return may berealized now with what is been offered by cell phone service providers.Other■ [Rating: 3]■ [Rating: 2]■ Generally related to ReliabilityItem #68:C-03Development of New AASHTO LRFD Tunnel DesignSpecifications(17)(46)NR 0 1 2 3 4 5SCOR 1 3 1 5 3 4RAC 2 6 8 6 8 12 7Standing Committee on Research■ The research project is very timely and much needed. The current Bridge LRFD Specification is very limited inaddressing tunnel design. This project will add significant depth to the current Specification.■ Currently, Caltrans has very limited design specification references for tunnels. Chapter 12 of AASHTO LRFD manual isour only reference. With all the new tunnels that are under design for the High Speed Rail this research will beimportant. The research will minimize our being dependent on foreign guides and references.■ This research is needed for LRFD implementation.■ [Rating: 4] There is a need to develop an LRFD-based tunnel design specification for adoption by AASHTO, as no suchspecifications currently exist, and is appropriate as an NCHRP sponsored project. There is no known similar effortunderway. FHWA has a technical manual on Design and Construction of Road Tunnels dated March 2009 which may berelevant in development of this LRFD specifications. Also, information from NCHRP project 20-05/Topic 41-05 onSynthesis of Design Information on Fires in Road Tunnels, which was initiated in 2009, should be useful in developmentof this specification.Research Advisory Committee■ Will benefit all states.■ This research may not get done within 36 months, due to broad scope of work that needs to be done and developingIV-47
