Traffic Management Simulator

The traffic management simulator (TMS) mimics the traffic control and routing guidance logic under evaluation. It receives as input real-time traffic data from the surveillance system, generates control and routing strategies, and updates the state of traffic control and guidance devices. TMS currently supports evaluation of route guidance, signal control, and incident management functions.
