| 摘 要： | 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,其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,并实现相位顺序、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,减少车辆的延误时间。

| Abstract: | A traffic signal two stage fuzzy control system for an urban intersection is discussed in this article;it can effectively decrease the number of fuzzy rules and is easy to acquire fuzzy rules.With the traffic situation changed, the method makes the phase order, the ratio of green signal and the cycle adaptively change;and we propose chaos optimization algorithm for the fuzzy sets of fuzzy controller;it makes the efficiency of passing increase and the time of vehicle delay decrease. |
