摘　　要：城市交通控制(UTC)是智能交通系统(ITS)中非常重要的组成部分,城市交通控制的主要任务之一就是交叉口的控制。传统的信号灯定周期控制不能满足交通流量实时变化的要求,控制效果不好。本工作提出了一种采用模糊逻辑进行道口信号灯控制的方法,通过模糊控制实时产生出最优的配时方案,仿真结果表明其优于定周期控制。Urban traffic control（UTC） is a very important part in intelligent traffic system. One of the main tasks in UTC is to control crossroad. Traditional signal lights timing cycle can＇t satisfy the requirement of real-time traffic flux change. Based on vehicle detectors,this article brings forward a method used to control signal lights at intersection through fuzzy logic control. This method reduces traffic jam effectively and brings an optimized algorithm of automatic time assignment for cross-road traffic lights. The simulation results show good performances compared with fixed timing cycle.
