Abstract: A macroscopic modeling framework for dynamic traffic phenomena on multidestination freeway and/or road networks with time varying demands is developed. A key variable of the model at each network node are the splitting rates of each traffic subflow with a specific destination. Two approaches are investigated for resolving the dynamic assignment and the route guidance problem: first, an optimal control approach for achieving a dynamic system or user optimum; second, a feedback concept for establishing dynamic user optimal conditions. The overall approach allows for integrated design of individual and/or collective route guidance, ramp metering, and signal setting in freeway and/or road networks. Some examples are provided.
