Study on integration of urban traffic control and route guidance based on multi-agent technology

The integration of urban traffic signal control (TSC) system and dynamic route guidance (DRG) system became a development trend of intelligent transportation system (ITS). This paper firstly describes the characters of integration of the two systems and the theory of multi-agent system. Based on the multi-agent system theory, we present a system architecture of the integration system of TSC and DRG with two kinds interactive agent model architecture: traffic signal control agent model and dynamic route guidance agent model. We then use the TSC agent model as an example to discuss the architecture and interactive mechanism of the agent models. The multi-agent system provides a possible means for the integration of TSC and DRG. Finally this paper studies the coordination model, indicates how these agent models coordinate.
