The invention discloses an automatic traffic light switching control system for relieving traffic jam, which not only performs traffic light control according to the traffic jam condition of a traffic light intersection to relieve the jam, but also considers the control condition of the adjacent traffic light intersection to the traffic jam to perform coordination control. According to the traffic light control method and the traffic light control device, the adjacent traffic light intersections are assisted to relieve congestion or the adjacent traffic light intersections are utilized to solve the congestion problem more quickly, so that comprehensive traffic optimization control is achieved, and compared with a scheme of only considering congestion to perform traffic light control, traffic congestion can be further relieved; by using the WIFI signal collector, the number of the mobile terminals starting WIFI within the preset distance range can be obtained, and whether the number of the mobile terminals is larger than the preset number threshold value or not is judged to obtain the judgment result; and therefore the switching time of the traffic light is adjusted, and the traffic pressure is effectively relieved.

    本发明公开了一种用于缓解交通拥堵的红绿灯自动切换控制系统,不仅根据本红绿灯路口的交通拥堵情况进行红绿灯控制,以缓解拥堵,同时考虑相邻的红绿灯路口对交通拥堵的控制情况,以进行协调控制,从而帮助相邻红绿灯路口缓解拥堵或者利用相邻红绿灯路口使自身更快的解决拥堵问题,从而达到全面的交通优化控制,相较于仅考虑自身拥堵进行红绿灯控制的方案,可以进一步的缓解交通拥堵;通过WIFI信号采集器能够获取预设距离范围内开启WIFI的移动终端个数,并判断所述移动终端个数是否大于预设个数阈值,得到判断结果,从而对红绿灯的切换时间进行调节,有效缓解交通压力。
