讨论单路口多相位的交通信号控制 ,控制方法采用实时模糊控制 ,提出以当前相的主队列、最近1 0秒车辆到达数、后继相的主队列三者决定信号配时的方法 ,给出了该三维模糊控制器的设计 .根据通过交叉口的车辆停驶过程 ,推导出交叉口平均车辆延误计算模型 .对上述控制器进行四相位交叉口的仿真试验 ,以通过交叉口的平均车辆延误作为性能评价指标 ,仿真结果表明 ,控制效果比较满意 ,优于定时控制方法
The control method of traffic signal with single phase and multiphase is discussed. The control method adopts real-time fuzzy control, and proposes the method of determining the signal timing based on the main phase of the current phase, the number of vehicles arriving in the last 10 seconds, and the main phase of the successor phase The design of the three-dimensional fuzzy controller is based on the process of stopping the vehicle passing through the intersection, and the calculation model of the average vehicle delay at the intersection is deduced.The simulation experiment of the four-phase intersection on the above controller is performed with the average vehicle delay at the intersection as Performance evaluation index, the simulation results show that the control effect is more satisfactory than the timing control method
