With Advanced Traveler Information Systems (ATIS) and Advanced Traffic Management Systems (ATMS), the traffic controller has the ability to communicate with vehicles, to provide real-time traffic information, and to offer route guidance instructions. Hence, one important task in ATMS/ATIS is the assignment of time-varying O-D trips to the various paths on a network based on some criteria and operational constraints. Most assignment models in the literature are static in nature which assume link flows and link trip time to be consistant over the projected time periods. While these assumptions may be appropriate for used in long-term planning appplications, they do not provide a reasonable approximation to the dynamic traffic behavior that occurs during the peak period which is essential to the effectiveness of the ATMS. Consequently, there is a need for advanced assignment model for ATMS/ATIS applications.
