Abstract: This research extends the performance and application of DYNASMART, a dynamic traffic simulation model which incorporates the three elements necessary for modeling traffic flow under information: (1) real-time traffic flow simulation, (2) dynamic path processing, and (3) microscopic consideration of the response of individual drivers to information. DYNASMART performs real-time modeling of traffic flow in which a specified percentage of vehicles are equipped with In-Vehicle Navigation Systems (IVNS). The CONTRAM assignment program is used to provide DYNASMART with realistic dynamic equilibrium routes for the initial path assignment of unequipped vehicles. The special-event traffic scenario, characterized by intense, short-term, nonequilibrium congestion in the presence of many alternative routes, is an ideal candidate for early and successful deployment of IVNS. The network and traffic demand of Anaheim, California are modeled with special events traffic generated by Anaheim Stadium. A dynamic Origin-Destination matrix was estimated using the COMEST program and observed link counts.
