摘　　要：模糊逻辑能很好地描述交叉口交通流的随机性和不确定性,因此非常适合应用于路口交通信号灯的控制。给出了一种采用分级模糊控制器进行路口信号灯控制的方法,以及模糊控制方法的结构、控制规则。最后由单片机实现信号灯的模糊控制,并对该控制器进行了仿真研究。结果表明它可以有效改善交叉路口的通行能力。Fuzzy logic can better describe the randomness and uncertainty of intersection traffic flow, so it is very applicable to intersection signal control. An intersection signal control method using two-stage fuzzy control is given, and the structure of controller and the fuzzy control rule are described in detail. Finally,the fuzzy control of traffic signal with single-chip microcomputer is achieved ,and an emulational research on this controller is carried out. The result shows that it can effectively improve the traffic capacity.
