A microscopic simulator for urban traffic systems

Based on microscopic traffic models, the object-oriented method and visualization technology are applied to the microscopic simulation of urban traffic systems, and a concise and flexible traffic simulator is developed. For an urban traffic network with 3 by 3 intersections, simulation results show that the vehicle behaviors in the traffic network accord with human traffic experience, and the movement curves of vehicles reflect the response of drivers to many traffic events. The fixed time signal control scheme is also compared with the fuzzy logic one in the simulation. The proposed approach can be adopted to study general large-scale traffic networks.
