交通灯控制系统的一种模糊算法

One Fuzzy Algorithm for Traffic Lights Control in Single Road Intersection

以车辆占据交叉口通道的长度作为模糊输入,采用模糊算法设计了一种新型的交通信号灯控制方法.克服不同车型的长短所带来的不精确性,使得单交叉路口的控制系统可以根据实时的流量灵活控制,在此基础上得到的绿灯延时更为精确实用.仿真结果表明,这样的控制方法在车辆延误时间上较之传统机械定时控制方法有所改善,公路利用率有较大提高.

This paper designs a new type of traffic control system which based on fuzzy algorithm, and abolishes traditional mechanical stable models, changes the traditional fuzzy input, uses the total length of the cars or buses as fuzzy length, no matter what kind of them, long or short. The simulation result indicates that if they just arrive at this area, most of them can go through the road intersection in less time than that in mechanical stable models. Thus utility rate of the road is considerably improved.
