一种道路交叉口多相位模糊控制方法及其仿真

根据现代城市交通系统的实际状况,研究了单个交通路口的信号控制,提出了一种多相位模糊控制方法。该控制方法不仅考虑了每个相位的车流情况,同时也考虑了绿灯相位的通行时间和红灯相位的等待时间,使得控制决策更能接近人的思维,从而达到更理想的控制效果。而且虽然增加了整个控制器的输入变量,但是并没有增加系统的复杂性。最后利用TSIS仿真软件进行仿真,结果表明该控制方法的效果要优于传统的感应控制,是进行路口信号控制一种实用和有效的算法。

A Fuzzy Control Method for Multi-phase Intersection and its Simulation

According to the real condition of modern city traffic,the control of a single multiphase signalized intersection is studied,and a novel fuzzy control methd is presented.By this method,not only the traffic flow of every phase is considered,but also the green time and red time.So the control and decision process are quite similar to the human thinking,and better control effect is achieved.Though more inputs are needed for controller,there is no increase of the complexity of the system.At last,the simulation is performed,with better result than that of the traditional actuated control,so it is an effective algorithm for intersection control.
