摘　　要：交通灯的控制是城市交通系统中一个重要的问题。本文探讨了一种新的交叉路口网交通灯的协调模糊控制方法。首先在交叉点和车道上设置流量检测器得到路口的交通数据；然后根据路网多个节点的交通动态特征，提出了一种模糊规则来控制交通信号灯的延长时间和相位变化，使得整个路网车辆的平均时延得到优化。这个方法与一种典型方法作了比较，并且给出了仿真实例，其结果相当令人满意。The controlling of traffic lights is an important aspect in city traffic system. In this paper, a new cooperative fuzzy control method of traffic lights is presented. At first, the traffic data are acquired from the detectors in the intersections and lanes. Then a novel fuzzy control rule is developed to control the phases and delay of traffic lights according to the dynamic characters of some correlative traffic intersections. The method can reduce the average time delay of vehicles effectively. The method is compared with conventional one by computer simulation, and the results are better and very satisfied.
