The invention discloses a vehicle red light running early warning method based on a vehicle-road cooperation technology. According to the invention, various data, such as green light time, traffic flow speed and the like, on a road are obtained through vehicle-road cooperation; the red light running probability of each vehicle on the road is calculated in real time; early warning of different degrees is carried out on the vehicle according to the red light running probability of the vehicle, a deceleration prompt is given for vehicle deceleration or rapid deceleration, and following vehicles on the same lane are prompted to decelerate; when the red light running probability is larger than 90%, a green light delay and early warning mode is adopted, vehicles running the red light can pass through the intersection at a certain speed within a certain redundant green light time, collision with other vehicles is avoided, the other vehicles can see vehicle deceleration early warning and perform corresponding deceleration, and traffic accidents are avoided. Through early warning of different degrees, the vehicle decelerates to give a deceleration prompt, other vehicles decelerate, recording of red light running of the vehicle is avoided, and the possibility of traffic accidents is also avoided.

    本发明公开了一种基于车路协同技术下车辆闯红灯预警方法。本发明中,先通过车路协同获得道路上的各种数据,比如绿灯时间,车流的速度等;对道路上的各个车辆进行闯红灯概率实时计算;通过车辆闯红灯概率对车辆进行不同程度的预警,车辆减速或者急减速给出减速提示,就提示同车道的跟车车辆减速;当闯红灯概率大于90%时,会取“绿灯延时+预警”模式,多余的一定绿灯时间使闯红灯车辆以一定速度通过交叉口,不会发生碰撞与其他车辆,还可以使其余的车辆看到车辆减速预警,也进行相应的减速,避免了交通事故的发生;通过不同程度的预警,使车辆减速给出减速提示,其余车辆也会减速,避免车辆闯红灯的记录,也避免了交通事故的可能。
