SIMULATION LABORATORY FOR EVALUATING DYNAMIC TRAFFIC MANAGEMENT-SYSTEMS

This paper presents a simulation laboratory for performance evaluation and design refinement of dynamic traffic management systems. The labo ratory consists of four integrated components: (1) a traffic managemen t simulator, which mimics the generation of route guidance and operati ons of traffic signals and signs; (2) a traffic flow simulator, which models individual vehicle movements and drivers' route choice decision s in the presence of real-time traffic information; (3) a surveillance system module, which collects real-time traffic data from sensors and probe vehicles in the simulated network; and (4) a control device mod ule, which implements control strategies and route guidance generated by the traffic management system under evaluation. The simulation labo ratory has been implemented in C++ using object-oriented programming a nd a distributed environment. It features a graphical user interface t hat allows users to visualize the simulation process, including animat ion of vehicle movements, state of surveillance sensors, traffic signa ls, signs, and so on. This modeling system provides a unique tool for evaluating integrated ATIS and ATMS applications in a computer-based l aboratory environment.
