饱和情况下交叉口可变相位控制系统设计

Design of Variable Phase Control System at Intersections in Saturation

通过分析路口饱和情况下大路口车流拥堵的原因,设计了一种可变相位的模糊控制系统,可以根据各车道的车流情况确定系统的相位,根据放行相位的车辆数确定绿灯时间。通过现场调研,路口拥堵多是因为相位交替时的路口内未通行车辆,所以设计系统应根据路口内车辆情况,实时延长路口清空时间。

A variable phase fuzzy control system is designed to determine the phase of the system according to the traffic condition of each lane, and the time of the green light is determined by the number of vehicles letting off phase. Through the field investigation, the congestion of the intersection is mostly due to the non passing vehicles in the intersection when the phase is alternating, so the design system should extend the clearance time of the intersection in real time according to the vehicle situation in the intersection.
