MULTI-PHASE FUZZY CONTROL OF SINGLE INTERSECTION IN TRAFFIC SYSTEM BASED ON GENETIC ALGORITHM

摘要

Single intersection in the traffic system is a complex system which has the nonlinear and uncertain characteristics. If the traffic states in the single intersection become more complex, the traditional timing control of the traffic lights is not suitable for the traffic control. A multi-phase fuzzy controller of the single intersection is proposed in this paper, by using the integration of the multi-phase control, and incorporating genetic algorithm into fuzzy control design to optimize fuzzy membership functions. The proposed control method is suitable for the different traffic states in the different times, and can achieve satisfactory control performance. The simulation experiment is implemented to prove the effectiveness of the proposed multi-phase fuzzy controller.
