中文摘要: 城市交通拥堵具有严重的危害性, 直接导致时间延误、能源浪费和废弃物排放增加, 降低居民生活水平. 现阶段, 基于平面交叉路口交通灯切换时间相对固定, 恶劣天气或发生交通事故时路口经常发生交通堵塞的实际情况, 本文提出了一种平面交叉口交通拥堵多方向交通灯运行时间自适应算法, 采取视频图像处理算法判断道路交通拥堵情况, 根据路况设置交通灯的工作时间, 并设计了相应的控制系统. 仿真结果表明, 在高峰期时段, 此自适应算法的车辆通行效率高于传统的交通灯运行时间控制方法.
Abstract:Urban traffic congestion is seriously harmful, directly causing time delays, energy waste, emission increase, and the living standards reduction of residents. At current cross-road intersection, traffic lights switching time is relatively fixed, the actual situation of traffic jams at intersections occur in bad weather or in the event of a traffic accident. Therefore, this study proposes an adaptive algorithm for multi-directional red light time to ease the traffic congestion at intersections. Using video image processing algorithm to judge road traffic congestion, we set the traffic light time according to road conditions, and design the corresponding control system. Simulation results demonstrate that the traffic efficiency by this proposed adaptive algorithm is higher than that of the traditional traffic light running time control method during the heavy traffic.
