Supersaturated traffic flow signal timing method and device based on fuzzy control

The invention provides a supersaturated traffic flow signal timing method and device based on fuzzy control. The method comprises steps 1 to 6. According to the method, the monitoring area is arranged beside the intersection, the traffic signal control model based on fuzzy logic is established, and the information of the vehicles entering and exiting the monitoring area is collected in real time based on interaction between the vehicles and the infrastructure, so that the maximum lane saturation of the current signal phase is calculated, and traffic flows with different saturation degrees can be flexibly coped with; and the traffic efficiency of the intersection can be improved and the congestion degree of urban traffic can be relieved. 本发明提供了一种基于模糊控制的过饱和交通流信号配时方法及设备。所述方法包括：步骤1到步骤6。本发明通过在交叉路口旁设置监测区域，建立基于模糊逻辑的交通信号控制模型，然后基于车与基础设施的交互实时收集进出监测区域的车辆信息，从而计算当前信号相位的最大车道饱和度，能够灵活应对不同饱和程度的交通流，有利于提高交叉口的通行效率和缓解城市交通的拥堵程度。
