摘　　要：针对固定周期的交通信号灯浪费道路资源的问题,提出一种模糊混合Petri网用于交通信号灯实时控制的建模方法。该模型结合本相位方向的排队长度和路口的车流量对本相位绿灯时长实时控制,再结合其他相位红灯时长和其他相位的排队长度,实时控制相序的变化。仿真分析表明,基于模糊混合Petri网对信号灯实时控制可最大程度降低车辆的停车次数。According to the problems of the road resources waste based on the fixed signal cycle, this paper provides a kind of Fuzzy Hybrid Petri Nets （FHPN） to simulate the real-time control for the traffic signal. The duration of the green light can be got by the fuzzy reasoning with the Fuzzy Reasoning Petri nets based on the queue length and the traffic flow, and then we can control phase sequence in time based on the queue length and the duration of the red light of other phases,The simulation analysis shows that the real-time traffic signal control based on the Fuzzy Hybrid Petri nets can reduce furthest the count of the vehicle stops.
