Abstract: Implementation of ATIS (Advanced Traffic Information Systems) and/or ATMS (Advanced Traffic Management Systems) are proceeding in many cities around the world, but only very few frameworks are available to study the effectiveness of these. Such systems are complicated thanks to complex interactions among the dynamics of path-based traffic conditions in the network, information/guidance supply strategies and the driver response in the form of their route-choice decisions. In view of the analytical intractability of these component phenomena, simulation frameworks could well be the only reasonable solution. DYNASMART (Dynamic Network Assignment Simulation Model for Advanced Road Telematics) is a program that we developed earlier that captures these key components in a flexible simulation framework that models individual vehicle movements using macroscopic traffic relationships and the driver decisions based on information at the network nodes. In this paper, we report on the recent enhancements that we have made to this model to make it more user-friendly, as well as the additional capabilities that we have incorporated to it.
