基于车头时距交通信号的模糊控制系统

Fuzzy control system of traffic signal based on the car-head time gap

以城市交叉口为研究对象,提出了一种基于车头时距的绿灯时间修正算法的交通流模糊控制方案,该方案在自适应模糊控制算法的基础上,增加了绿灯时间修正算法模块,从而对绿信比进行了优化,并用Mat-lab软件进行了仿真研究。仿真结果表明,在相同的交通环境下该方法比没有基于车头时距的对绿信比进行优化的自适应模糊控制系统方案有效。

Take the urban intersections as the object of study,a fuzzy control system of traffic flow is presented based on green light time correction algorithm of the car-head time gap.The green light time correction module is added,and the green ratio is optimized on the basis of adaptive fuzzy control algorithm.The simulation research is carried by using Matlab software.The simulation results show that this method is more effective than the previous adaptive fuzzy control algorithm without car-head time gap in the same traffic situation.
