PROGRAM AREAS: TISEworked on new projects including the modeling of a 25-milesection of I-81 between Christiansburg <strong>and</strong> Roanoke for the I-81 reconstruction project <strong>and</strong> a characterization of the trafficdem<strong>and</strong> on Route 24 at Appomattox Court House NationalPark under the sponsorship of the National Park Services.Rakha redesigned the Traffic <strong>Engineering</strong> course <strong>and</strong> cotaughtTraffic Characteristics <strong>and</strong> Flow. He offered two shortcourses in Canada <strong>and</strong> was a guest speaker at the Universityof Maryl<strong>and</strong>. His team published 12 journal publications, nineconference proceeding publications, <strong>and</strong> made 18 conferencepresentations. In addition, Rakha serves as an associate editorfor the 7th IEEE International Conference on IntelligentTransportation Systems <strong>and</strong> was one of 20 recipients of theResearch Fellow Award from the college of engineering.Swarm intelligence to route vehiclesDusan Teodorovic continued work developing new methodsto route vehicles on the ground using swarm intelligencetechniques <strong>and</strong> collaborated with Antonio Trani’s group onthe development of a decision support, computer simulation<strong>and</strong> optimization model to measure the economic impacts ofdeploying advanced technologies at airports. He taught classeson transportation network analysis <strong>and</strong> soft computingapplications in transportation.Air transportation researchThis year, the air transportation research group madeprogress in several areas. Trani, with colleagues Hojong Baik<strong>and</strong> Howard Swingle, as well as graduate students SenanuAshiabor, Nick Hinze, Yue Xu, An<strong>and</strong> Sheshadri <strong>and</strong> KrishnaRama-Murthy, continued the development of a large-scale aviationplanning model to study the impacts of various aerospacetechnologies in the U.S. national airspace system (NAS).They have been developing the model for the past three yearsto study the impacts of on-dem<strong>and</strong> air taxi services usingsmall aircraft across the country (see article, page 8). Thismodel will also be used in the coming months by the NASALangley Research Center to study the economic <strong>and</strong> operationalimpacts of radical aerospace vehicle concepts such asultra-short takeoff <strong>and</strong> l<strong>and</strong>ing (USTOL) commercial aircraft inthe NAS. For the FAA, Trani, Teodorovic, Baik <strong>and</strong> graduatestudents Stephanie Chung <strong>and</strong> Aniruddha Kane developed adecision support, computer simulation <strong>and</strong> optimizationmodel to measure the economic impacts of deploying30Ground penetrating radar testing forthe premium pavement investigationadvanced technologies at airports. The model is a first steptoward helping the FAA make more informed decisions aboutthe true life-cycle costs of deploying technologies for alleviatingairport congestion. With colleagues at the University ofCalifornia Berkeley <strong>and</strong> MIT, Trani participated in an FAAstudy of the impacts of advanced avionics on-board new <strong>and</strong>future aircraft (like the Boeing 7e7 Dreamliner) in the NAS.This study surveyed seven U.S. airlines to determine the complianceof the existing aircraft fleet with various levels ofrequired navigation performance (RNP) <strong>and</strong> their impact inenroute <strong>and</strong> terminal area operations.Trani offered a four-day computer-aided short course onaviation system modeling on behalf of NEXTOR—the NationalCenter of Excellence for Aviation Operations Research—toFAA <strong>and</strong> various aviation industry participants. This shortcourse was delivered to 30 participants at the NorthernVirginia Center <strong>and</strong> demonstrated computer-based models tostudy air transportation systems.Pavement materials <strong>and</strong> testingImad Al-Qadi, <strong>and</strong> the Roadway Infrastructure Group,continued research on pavement materials <strong>and</strong> design <strong>and</strong>nondestructive testing. This includes working, in collaborationwith VTRC <strong>and</strong> NRC of Canada, on the Consortium onDevelopment of Performance-Based Guidelines for CrackSealants with participation from 13 state DOT’s <strong>and</strong> 13Canadian industrial, local, <strong>and</strong> government agencies. Thegroup is developing finite element models for pavement damage,developing an overly design approach to control reflectioncracking in pavements, calibrating pavement design modelsutilizing instrument response, developing a model to accuratelypredict the pavement thicknesses from ground penetratingradar data, developing shift factors to correct for the effectof laboratory prepared asphaltic materials on their engineeringproperties when compared to those in-situ measured characteristics,<strong>and</strong> assisting in deploying new technologies in severalstates. The group contributed 12 presentations at theannual Transportation Research Board meeting, in addition topapers, reports, presentations, <strong>and</strong> several invited talks atnational <strong>and</strong> international conferences <strong>and</strong> professional meetings.Al-Qadi co-chaired the 5th International RILEMConference on Pavement Cracking in Limoges, France <strong>and</strong>was a keynote speaker at both the 10th International Conferenceon Structural Faults <strong>and</strong> Repair in London <strong>and</strong> the 5thInternational Symposium on Nondestructive Testing in <strong>Civil</strong><strong>Engineering</strong> in Berlin. He organized several technical sessionsat international conferences <strong>and</strong> served as a guest editor ofthe July <strong>2004</strong> issue of the ASNT Materials Evaluation SpecialEdition on NDE of Pavements <strong>and</strong> serves as the North Americaeditor of the Construction <strong>and</strong> Building Materials Journal. Al-Qadi serves on more than 20 technical committees; he is currentlychairing the TRB Committee on Sealants <strong>and</strong> Fillers forJoints <strong>and</strong> Cracks <strong>and</strong> the TRB subcommittee on geosyntheticsin pavement systems. He received the <strong>2004</strong> Limoges Medalof Merit for his contribution in pavement technology. Al-Qadihas accepted a position at the University of Illinois at Urbana-Champaign <strong>and</strong> has left Virginia Tech.In addition to the full-time faculty, adjunct professors contributedto the program’s education mission. Jacob Craig ofAnderson <strong>and</strong> Associates taught the undergraduate GeometricDesign of Highways course. Sam Tignor continues to provideadjunct instruction in the areas of traffic engineering, safety,<strong>and</strong> highway signing at the Northern Virginia campus.
