This report discusses the use of a dynamic traffic assignment (DTA) model as an analytical tool for a congestion management system (CMS). State agencies and metropolitan planning organizations have expressed a growing need for improved analytical tools to evaluate congestion mitigation strategies as part of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA). The static assignment models used today are not capable of satisfactorily addressing the CMS requirements. The difficulties associated with the traditional static approaches provide an opportunity to evaluate the feasibility of using DTA for transportation planning in the context of congestion management. This research examines the capabilities introduced by dynamic traffic assignment and its potential to play a valuable role in congestion management. Experiments include the evaluation of several congestion management strategies with static and dynamic traffic assignment models to stress the strengths and weaknesses of both approaches. Finally, the CMS functional requirements are reviewed in connection with the static and dynamic modeling capabilities.
