Message from the DirectorTo friends and clients of ITRE, I am pleased to submit our 2011 Annual ActivityReport. We have strived to make this report both informative and pleasant to read.We hope to have achieved both objectives in this year’s edition. I am happy to reportthat ITRE continues on a path of growth and recognition both nationally andinternationally. We also continue to experience the effects of the economicslowdown, resulting in a reduction in funding levels, an area which continues to be achallenge.Financially ITRE is on a good footing. We have maintained the integrity of ouroperating staff, been able to keep up with technology for our research and educationneeds, and are developing a national presence in the competitive research arena.Our in-house expenditures dropped slightly by 2.75% this year. In addition, ITRE is nolonger passing through NCDOT research dollars to NC State University and other stateuniversities, thus artificially decreasing our overall expenditures by a significant$1.5M. Starting next year, we will only report trends for in-house expenditures. Onthe positive side of the ledger, we have increased our expenditure share of federaldollars from 9 % to 12% this year. And despite the slight drop in expenditures, theoverhead dollars generated by our projects increased by nearly 10%.One reason for our success this past year isour increasing win-rate of federally andother out-of-state funded projects . . .This report is replete with statistics and graphics, and I will refrain from summarizingthem in this limited space. However, I want to highlight a few key initiatives wecontinue to aggressively pursue as an Institute. International outreach to sister universities, resulting in the formulation andsigning of Memoranda of Understanding (MOU) this year between NC State and IIT-Delhi in India, and Stellenbosch University in South Africa, with ITRErepresenting NC State. Leading major national proposals; our Center for Transportation and theEnvironment (CTE) is leading a Tier-1 Consortium proposal for the US DOT(currently under review); ITRE has also partnered with the Civil EngineeringDepartment on a pre-proposal to the National Science Foundation in the area ofSustainable Transportation under the NSF Partnership for International Researchand Education (PIRE), also under review. Integrating graduate students within the ITRE environment. This year we havehad the largest number of supported graduate students in ITRE’s history, helpingus to fulfill one of our key goals of capacity building in the transportation area inthe University. Improving our visibility at the TRB Annual meeting. Our efforts are clearlypaying off. In January 2012, we will have over 30 scheduled events andpresentations that involve our staff, students and affiliated faculty.In conclusion, I trust the reader will concur that ITRE is on a positive path towardsgrowth and quality. It also goes without saying that this success could not be possiblewithout an administrative staff that is second to none, and an incredibly motivatedtechnical staff that always strives to do better than the year before!Nagui Rouphail, DirectorDecember 2011 ITRE Annual Activity Report Page 3

Annual Activity Report - 2011Institute for Transportation Researchand Education (ITRE)at NC State University Centennial CampusThis report summarizes ITRE’s activities for the year 2011 and providesbackground information on the Institute’s history, mission, goals, andobjectives. It also provides an overview of ITRE’s finances, personnel, andtechnical activities during the year. As in years past, the Institute hasmaintained and in some instances expanded its programmatic activities.Highlighted globes show the campuses withinthe University of North Carolina System.Center DescriptionThe Institute for Transportation Research and Education (ITRE) is an Inter-Institutional Center of the University of North Carolina system. Chartered bythe North Carolina General Assembly in 1978, ITRE carries out research,training, and technical support activities in surface and most recently airtransportation for a host of national, state, and local clients to address thenation’s critical transportation issues. ITRE is committed to leadership in thestudy of transportation issues through fostering analytical thinking,integrating technology in education and research, serving as a catalyst forproblem solving, and cultivating professionals and students dedicated toexcellence in transportation.ITRE is an inter-institutional centerwithin theUniversity of North Carolina systemCurrently, ITRE is organized into six program groups covering 1) HighwaySystems; 2) Visual Analytics, Modeling and Simulation (VAMS); 3) NorthCarolina Local Technical Assistance Program (NC LTAP); 4) PublicTransportation; 5) Pupil (school) Transportation; and 6) the Center forTransportation and the Environment (CTE). A high-level organizational chartis shown in Exhibit I. Our programs are guided and monitored by an AdvisoryCouncil whose membership has recently been increased. The current ITREAdvisory Council membership is shown in Exhibit II.Summary of ITRE GoalsITRE’s strategic plan, developed in 2002, has set forth five major institutewidegoals: Increase national visibility Conduct and disseminate research that impacts the transportationcommunity Sustain and enhance educational opportunities to improve theknowledge and skills of transportation professionals Strengthen the relationship with, and gain recognition within, theUniversity system Provide superior technical assistanceITRE is housed in the Research IV Building onNCSU’s Centennial Campus.These goals are currently being achieved through various objectives, such asincreasing national exposure through conference presentations, publishingresearch, outreach efforts, and increased national project awards.Additionally, the Institute continues its training efforts on a national,regional, and state level, while promoting collaboration with faculty in thedepartment of Civil, Construction, and Environmental Engineering at NorthCarolina State University and at other UNC system institutions.This report provides a glimpse of this year’s activities and accomplishmentsin reaching these goals and objectives.

Summary of ITRE’s FinancesExhibit III data shows the most recent Fiscal Year, July 1, 2010 through June 30, 2011, for which complete financial information isavailable. Expenditures are broken down by the funding source.Overall, about 7% of all FY 10/11 ITRE expenditures representState Appropriated Funds related to administration, withadditional operations support of 4% coming from Indirect CostReturn. Both have slightly increased from FY 09/10.Exhibit IIIExpenditures by Funding Source FY 10/11State of North Carolina and Federal Contracts total 65% ofall activity. Those figures have increased 13% compared to52% for the FY 09/10.Sales and Service activity at 10% has increased with moreattendees and from registration fees for workshops.Pass-through projects to other departments at NCSU (1%)and other UNC universities (2%) have significantly decreasedin volume from the previous year (20%). NCDOT now hasseparate master agreements with all NC universities.Other Contracts (11%) which includes project activity primarilyfor municipalities, and may include funding from other states,has not changed from the previous fiscal year.Exhibit IV shows how ITRE’s FY 10/11 expenditures are allocated by program area. As has been the case in the past few years, theHighway Systems program continues to be our largest generator of expenditures, accounting for nearly 33% of all ITRE expenditures.This is followed by the CTE (at 14%) and Public Transportation (at 13%) groups. Other groups and administration contribute at variousrates that are below 12%.The “Institute” expenditures include state appropriations, facilities and administrative receipts, professional development and otheraccounts managed by the Institute as a whole.Exhibit IVExpenditure Allocations by Program AreaDecember 2011 ITRE Annual Activity Report Page 6

Exhibit V shows the distribution of expenditure sources by program area. This chart serves to highlight where each group primarilyexpends its funds. We have categorized those funds as State, Federal, Other, and Other Federal. The category of “Other-Federal” iscomprised of projects where ITRE is a subcontractor to a private company who is the prime on a federally funded project.The “Other” category includes expenditures from contracts we have with other states, not-for-profit organizations, the private sectorand from course registrations. This exhibit highlights the fact that ITRE is still predominantly funded from NC state and local funds,although there are some significant variations across program areas.Exhibit VExpenditures by Program Area and Funding SourceExhibit VI tracks ITRE’s annual expenditures over the past five years. The total expenditures include all pass-through projects toentities outside ITRE.ITRE’s total expenditures have decreased in FY 10/11 compared to the previous cycle. This is primarily due to a reduction of close to$1,500,000 experienced in pass-through funding to other NCSU departments and UNC universities as a result of the changes incontracting policies with NCDOT. In a review of strictly ITRE-staffed projects, the decrease is only 2.77%, also attributed to areduction in pass-through expenditures incurred at ITRE.Exhibit VITracked Expenditures in a Five-Year PeriodDecember 2011 ITRE Annual Activity Report Page 7

Exhibit VII summarizes ITRE’s productivity trends over the past five years. The top line represents the ratio of total annualexpenditures divided by ITRE’s state appropriation.Total expenditures include all pass-through research projects (internal to NCSU and external to other universities) and our portion ofcollected indirect costs distributed back to ITRE based on the previous year’s expenditures.The middle line excludes all pass-through projects from annual expenditures when calculating the ratio, basically reflecting the valueof in-house research activities. In both cases, the ratio continues to be well above the indicated 4.0 minimum threshold cited in theUNC Office of the President Report (lower line).Even in these difficult economic circumstances, ITRE is demonstrating itself to be a valuable and cost-effective asset to the state ofNorth Carolina with a productivity ratio of over 13:1.Exhibit VIITracked Expenditures/State Appropriated FundsExhibit VIII shows that ITRE continues to generate Facilities and Administrative (F&A) funds for its operations, as well as for NCSU.In the last fiscal year we generated nearly $900,000 of F&A dollars from our local, state, and federal projects, an 11% increase over theprevious FY. Even though overall expenditures were slightly lower, ITRE generated increased F&A through projects bearing higher F&Areturn. For example our full-overhead federal contracts account for 12% of expenditures this year, compared to 9% last year.In the past, between 33-35% of the F&A funds were returned to help operate the Institute and provide incentives for improving ournational visibility, but now only 27% is being returned due to a new allocation formula.Exhibit VIIITracked Facilities & Administration GenerationDecember 2011 ITRE Annual Activity Report Page 8

Report FHWA/NC/2009-05, September 2011.Recent bicycle crashes that occurred inthe Winston‐Salem area promptedNCDOT to determine that similar crashtypes, patterns, and rates are occurringon a statewide basis, and thatpedestrians are also vulnerable. As aresult, the Bicycle and PedestrianProgram at ITRE was tasked withcreating a process to discern the toppriorities in addressing bicycle andpedestrian safety in North Carolina.The OREd program uses a process calledIntegrated Planning for School andCommunity (IPSAC) to forecast theimpacts of anticipated growth on K‐12student populations, and to providedistricts with data‐driven planning toolsfor locating future school sites anddetermining attendance zones.December 2011 ITRE Annual Activity Report Page 21

The adjoining tables summarize our record ofaccomplishments in providing student support, indicating increasedgraduate student participation in ITRE research. In 2011, we had thehighest number of supported research graduate students in our history(20). More importantly, much of the graduate student support has comefrom federal research dollars from agencies such as the National ScienceFoundation, the National Cooperative Highway Research Program(NCHRP), the Strategic Highway Research Program (SHRP-2), the FederalHighway Administration and the Environmental Protection Agency. Manyof the graduate students at ITRE have received full ResearchAssistantship support. We also provided meaningful research experiencesfor our undergraduate students, primarily in the areas of transportationsystems, rail operations and a variety of other fields. For the first time,ITRE also recruited a high school student, Kaitlyn Tsai, from theAcademy of Information Technology (AOIT) program, Apex High School,Apex, NC.Post-Doctoral Fellows and Visiting ScholarsDr. Dae-Seop Moon, Visiting Scholar, who is in charge of theTransportation and Logistics Department at the Korea Rail ResearchInstitute, was hosted at ITRE from February 2010 through March 2011.Dr. Hyejung Hu, who defended her doctoral dissertation in December2008 was given a Post-Doctoral appointment to support researchprojects that required transportation modeling skills at the meso-scopiclevel, which was part of her dissertation research at ITRE through May2011.Dr. Margarida Coelho, PhD, Post-Doctoral Fellow (University of Aveiro,Portugal) has continued her collaboration with ITRE this year, involvingthe staff in a study funded by the Lisbon Municipality on modeling accesscontrol alternatives to downtown Lisbon, and testing their air qualityimpacts.Seyedbehzad AghdashiAbseen AnyaZachary BuggThomas ChaseBurke FoleyTyler FowlerFederico GontarukAnxi JaiSangkey KimPaul KuIssac KumarBo LingChenhao LiuTed MansfieldLouis MaraisSoheil SajjadiKaty SalamatiHassan SwidanGuilhermina TorrãoYulin LiuGary AdamsJamie BortHunter BrownJeff ChangMichael CorwinAnthony EncarnacionBrooks HesterDylan HorneKyle HoveyAnna JacksonMark JulisEthan MabryLuke PerkinsElizabeth ScottKaitlyn TsaiJon SkinnerAndy WagnerKagure WamunyuZachary Bugg, Katy Salamati, and Soheil Sajjadi put theirknowledge of transportation to the test at the 2011Southern District Institute of Transportation EngineersTraffic Bowl and walked away with the first‐placescholarship.December 2011 ITRE Annual Activity Report Page 22

Pupil Transportation GroupITRE is the only research center in the nation with a program groupdedicated to addressing school travel safety and operation topics.Through the applications of transportation engineering principles,operations research, and technology to the operation and managementof multi-modal school transportation, the Pupil Transportation Groupconducts two major services: Transportation Information Management Systems (TIMS). TheTIMS program area provides support and consultation of a GIS-basedschool bus routing and scheduling software system used by all publicschool systems in NC. Through the use of the software and supportfrom the Pupil Transportation Group staff, school systems in NCwere able to design and implement cost-cutting transportation plansduring the recent difficult economic years. OREd Program (www.itre.ncsu.edu/OREd). The OperationsResearch and Education Laboratory (OREd) conducts populationforecasts, land use studies, location optimization, and GIS analysis.By integrating schools and community planning data and goals, theOREd assists school systems in developing data-driven and policybasedfacility and assignment plans.The Pupil Transportation Group also provides Web site hosting andmaintenance for three (3) nationally-recognized agencies:National Association for State Directors of Pupil Transportation Services(www.nasdpts.org); Transportation Research Board SchoolTransportation Subcommittee (www.itre.ncsu.edu/anb10_6); and NCSchool Bus Safety (www.ncbussafety.org).Visual Analytics, Modeling and Simulation Group(VAMS)VAMS researchers continued their analysis and program evaluationsupport of the two major Highway Patrol motor carrier enforcementprograms: Motor Carrier Safety Assistance Program (MCSAP) and TruckSize and Weight. These programs are funded by FMCSA and FHWArespectively. These programs provide the primary means for VAMSdevelopment of operational GIS-related capabilities.VAMS’ analysis work for the NC State Highway Patrol (NCSHP) and NCDOTcontinues to provide an empirical basis for the consideration of safetyand roadway infrastructure issues associated with the trucking industry’spush for “higher productivity (heavier, longer) vehicles” (HPVs). ITRE’sdevelopment of a Roadway Vulnerability Index has been in direct supportof the infrastructure protection mission of the NCSHP Motor CarrierEnforcement program. In the analysis area, ITRE introduced its on-lineCoverLab concept which represents an effort to integrate GIS, datavisualization, and emerging business intelligence (BI) concepts.During this past year, VAMS researchers continued efforts to elevate thelevel of analysis for truck safety to the carrier level and to focus on theoperational mission of trucking to transport freight. This work alsoprovides support of ITRE’s inputs to North Carolina’s development of astatewide logistics (freight) plan as well as to efforts on the part ofCharlotte to develop a future Freight Mobility Plan.VAMS research staff also supported an effort co-funded by the VA and NCState Departments of Transportation which focused on the attributes ofcarriers involved in fatal combination unit truck (CUT) crashes. Theresults of the study documented the increased risk of fatal CUT-involvedcrashes for small carriers as well as the increased risk of fatal CUTinvolvedcrashes on non-interstate roads in both states.December 2011 ITRE Annual Activity Report Page 30
