目前,大多数城市交通流量越来越大,交叉路口的交通信号控制越来越重要,传统的定时控制与分时区定时控制已经不能有效的满足实际的需要。根据城市交叉口交通流的特点,文章提出一种实用的自适应控制器的设计,实时检测每个方向的车辆排队长度,估算出该路口的某时段的平均车流,实时调整各方向绿灯的通行时间,从而使每个路口能够通行尽可能多的车辆。
At present, the traffic flow in most cities is getting bigger and bigger, the traffic signal control at the intersection is more and more important. The traditional timing control and time-zone timing control can not effectively meet the actual needs. According to the characteristics of traffic flow in urban intersection, this paper presents a practical design of adaptive controller, real-time detection of vehicle queuing length in each direction, estimates the average traffic flow of a certain period of intersection, real-time adjustment of green traffic in all directions Time, so that each intersection to pass as many vehicles.
