Simulation Laboratory for Evaluating Dynamic Traffic Management Systems

Abstract

This paper presents a simulation laboratory for performance evaluation and design refinement of dynamic traffic management systems. The laboratory consists of four integrated components : (1) a traffic management simulator, which mimics the generation of route guidance and operations of traffic signals and signs ; (2) a traffic flow simulator, which models individual vehicle movements and drivers' route choice decisions 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 module, which implements control strategies and route guidance generated by the traffic management system under evaluation. The simulation laboratory has been implemented in C++ using object-oriented programming and a distributed environment. It features a graphical user interface that allows users to visualize the simulation process, including animation of vehicle movements, state of surveillance sensors, traffic signals, signs, and so on. This modeling system provides a unique tool for evaluating integrated ATIS and ATMS applications in a computer-based laboratory environment.
