The invention discloses a traffic signal lamp control method and system based on a radar. The method comprises the steps: judging whether there is a vehicle waiting in a first direction and a second direction through the radar, and enabling the radar to be powered through a traffic signal lamp; judging whether a vehicle passes in the third direction and the fourth direction or not at least through a radar; switching green lights in the third direction and the fourth direction to red lights and switching the red lights in the first direction and the second direction to green lights at least under the condition that no vehicle passes in the third direction and the fourth direction and vehicles wait in the first direction and the second direction; and after switching, enabling the traffic signal lamps to operate according to a pre-configured alternating rule. According to the invention, the problem of road resource waste caused by the traffic signal lamp control mode in the prior art is solved so that the road passing time of vehicles is shortened, and the utilization rate of road resources is effectively improved.
本申请公开了一种基于雷达的交通信号灯控制方法和系统,该方法包括:通过雷达判断第一方向和第二方向上存在车辆等待,其中,所述雷达通过所述交通信号灯进行供电;至少通过雷达判断所述第三方向和所述第四方向上是否有车通过;至少在所述第三方向和所述第四方向上没有车辆通过并且所述第一方向和所述第二方向上有车辆在等待的情况下,将所述第三方向和所述第四方向上的绿灯切换为红灯,将所述第一方向和所述第二方向上的红灯切换为绿灯;在切换之后,交通信号灯按照预先配置的交替规则运行。通过本申请解决了现有技术中的交通信号灯控制方式所导致的浪费道路资源的问题,从而缩短了车辆的道路通行时间,有效提高了道路资源的利用率。
