A traffic light intelligent control method based on road real-time capacity comprises the following steps of 1, calculating phase initial green light duration according to real-time traffic flow information, and optimizing the green light duration of each phase by using an algorithm, 2, judging whether the green light duration is reasonable or not, and performing fine adjustment to avoid traffic jam caused by overlong green light duration of a certain phase, 3, calculating the road flow processing capacity according to the real-time traffic flow information, and calculating the phase priorityin combination with the vehicle queuing length and the vehicle average waiting time, and 4, enabling the phase green light duration and the phase sequence to act on the traffic lights. The method hasthe characteristic of solving the problem of road congestion by reasonably utilizing the real-time capacity of the adjacent roads.
一种基于道路实时容量的交通灯智能控制方法,包括以下步骤:步骤1,根据实时车流量信息计算相位初始绿灯时长,并利用算法优化各相位绿灯时长;步骤2,判断绿灯时长是否合理,进行微调避免某个相位绿灯时长过长引起交通拥堵;步骤3,根据实时车流量信息计算道路流量处理能力,并结合车辆排队长度、车辆平均等待时间计算相位优先级;步骤4,将相位绿灯时长以及相位顺序作用于交通灯;具有通过合理利用相邻道路实时容量来解决道路拥堵问题的特点。
