The Traffic Flow Model for Single Intersection and its Traffic Light Intelligent Control Strategy

From the viewpoint of macroscopic dynamic characteristics of single intersection traffic flow, a commonly used macroscopic dynamic deterministic traffic flow model for traffic control is developed. Furthermore, according to fuzzy control theory and the policeman´s experience, multi-phase traffic light control strategy based on the length of the waiting queue is presented. In this strategy, the length of queue is regarded as the control object and the length of queue on the contiguous phase is used to determine the timing plan. The simulation research and actual application show that this new control strategy is more near to the manned decision process and can perform the multi-phase signal traffic control of a single intersection more effectively than the fixed-time plan. The application result is satisfied
