Project objective: 1) to deploy DynaMIT for off-line evaluation at a Virginia TMC and evaluate the accuracy of prediction, 2) to deploy DynaMIT for on-line evaluation at a Virginia TMC and evaluate the accuracy of prediction as well as gathering feedback from TMC staff, and 3) to refine DynaMIT if the lessons learned from this study justify.
Project abstract. DynaMIT integrates a detailed network traffic model with models of traveler behavior. Through combining information from historical databases with real-time inputs from field installations (surveillance data and control logic of traffic signals, ramp meters, and toll booths), DynaMIT generates estimates of future traffic conditions. This project will evaluate the performance of this prototype dynamic traffic assignment program using a manageable network in Hampton Roads Smart Traffic Center. The project will consider both off-line and on-line testings.
Tasks. 1) Data collection and network coding 2) Data reduction and O/D development 3) Calibration/validate of DynaMIT program, 4) off-line testing 5) On-line testing 6) Compose final report
Milestones. This project will be completed by August 31, 2005.
Student involvement. 1 GRA
Budget (Pending on FHWA contract) $140,000
Relation to other research: This project will support the on-going project, "Hampton Roads Simulation"
Technology transfer: Papers in professional journals and presentations at conferences
Potential benefits: This prototype DTA model will enhance day-to-day operations in the HRSTC.
