基于两级模糊控制的交叉路口多相位控制

用模糊控制方法对交叉路口的交通信号进行控制,提出一种面向城市交叉路口的交通信号两级模糊控制系统.该系统能够分散处理交通信息参数,有效减少模糊规则数,易于提取模糊规则,实现相位顺序、绿信比和周期均随着交通状况的变化而自适应变化;并利用混沌优化对模糊控制器的隶属度函数进行优化搜索,从而提高交叉路口的通行效率,减少车辆的延误...

Researches on Multi-phase Control of Urban Intersection Based on Two Layer Fuzzy Controller

The traffic signal control method in isolated intersection is discussed. According to a traffic signal two layer fuzzy control system for an urban intersection, the number of fuzzy ruies can be effectively decreased. The fuzzy rules is easy to be acquired. With the traffic situation changed, the phase order, the ratio of green signal and the cycle are made to change adaptively ; and chaos optimization algorithm is proposed for the fuzzy sets of fuzzy controller;the efficiency of passing increases;and the time of vehicle delay decreases.
