【摘要】 针对最常见的十字交叉口,以平均延误最小为目标,设计了四相位两级(观测级、决策级)模糊控制器,包括红灯相位选择模块、绿灯相位观察模块、决策模块等三个模块。所建立的交叉口车辆生成模型、交通信号控制模型以及车辆延误模型,通过MATLAB 7.0编写的程序,进行仿真分析。结果表明:在同样交通条件下,相对定时控制和感应控制,模糊控制的车辆平均延误时间分别降低了25.2%和16.5%。更多还原

【Abstract】 Aimed at minimizing the average delay time for the most common cross intersections,this paper proposes a design of the four phases and two-stage(observation level,decision-making level) fuzzy controller composed of red phase model,green phase model,and decision-making model.The development of the vehicle generation model,the traffic signal control model and the vehicle delays model and the simulation of the corresponding programs produced by MATLAB 7.0 show that with the same traffic conditions,fuzzy control gives vehicle average delay time 25.2% and 16.5% lower than timing control and sensor control.更多还原
