摘要: 提出一种基于模糊逻辑控制的交叉路口群信号控制器, 通过收集由交叉路口检测器获得的车流量信息制定模糊控制规则, 给出交叉路口绿灯相位和相位转换次序, 以控制路口信号, 并与相邻路口的信号进行协调。仿真结果表明, 该控制器能适应多个路口的车流变化, 减少车辆平均延误。Abstract: This paper presented a fuzzy logic controller and made a comparison of its performance with other controllers. The fuzzy rules was established by gathering the traffic flow information from the detectors placed in different intersections, and the green phase and the phase sequences at an intersection were obtained to control its traffic signals and cooperated with its neighbors. Simulation results show that the presented controller can adapt to the conditions of traffic flow well, and decrease the average delay time at multi-intersections.
