摘要: 基于车流阻塞参数b,设计含绿灯延长和相位选择2个模糊控制器的多相位交通信号控制系统。根据当前路口和下游路口参数,输出当前通行相位绿灯延长时间。若延长时间为0,则进入相位选择模糊控制器,输出下次通行相位。仿真结果表明,该设计方法可有效控制多相位路口的交通信号。

Abstract: This paper designs a multi-phase traffic signal control system based on congest parameter b of traffic flow. The system includes prolong of green light fuzzy controller and phase-choosing fuzzy controller. The first fuzzy controller’s output is the prolonged time of current green phase according to congest parameter of traffic flow of current cross and next cross. If the prolonged time is zero, it will enter phase-choosing fuzzy controller, whose output is the next phase to perform. Simulation result shows that this design can do well in controlling multi-phase traffic signals control.

Key words: congest parameter of traffic flow, phase-choosing, fuzzy control
