一种基于车头时距交通信号的模糊控制系统

A Taffic Signal Fuzzy Control System Based on the Headway

以城市交叉口交通流控制为研究对象,提出了一种基于车头时距的绿灯时间修正算法的模糊控制方案,给出了系统的模型和模糊控制器的设计,并结合兰州某十字路口实测的交通数据进行了仿真验证.仿真结果表明:在相同的交通环境下该方法比常规的模糊控制系统方案有效.

A fuzzy control system of green time adjusting algorthm based on the headway is proposed by taking the traffic flow of the urban crossing as the object of study,and the system model and design of fuzzy controller are presented,then it is simulated and proved by the actual traffic data of an intersection of Lanzhou.The result indicates that the method is more effective than the traditional fuzzy control system in the same traffic environment.
