摘要
提出基于车流量预测的动态调整相位最大绿灯时间的模糊控制系统结构。用模糊控制方法对单路口交通信号进行控制,决定绿灯时间分配。将此方案应用于北京劲松东口交叉口作为研究背景,仿真结果表明,控制效果优于现行的定时控制。该模糊控制方案能更有效地处理随机性较大、不确定性较强的交通流。
A fuzzy control system structure for an urban junction was proposed. The traffic flow in the next cycle was estimated, and the maximum time of green light was adjusted dynamically. The fuzzy controller was responsible for controlling the length of the green time. A simulation experiment was carried out to measure the capability of above fuzzy controller at Beijing Jinsong East Intersection. The simulation shows that the fuzzy method outperforms the fixed-time method. The strategy can deal with more stochastic and more uncertain traffic flow.
