The invention discloses a method for early warning vehicles behind a highway traffic abnormal point. The method comprises the following steps: firstly, obtaining the position of road traffic abnormality, then judging whether the sight of the driver of the vehicle behind the abnormal point is blocked or not, and dividing the type of the vehicle behind according to a judgment result; and finally, performing personalized early warning according to the type of the rear vehicle. The invention further discloses a system for realizing the method. The system comprises a plurality of personalized earlywarning devices which are continuously mounted on the road side of the highway at intervals of N meters, and each personalized early warning device comprises an integrated sensing module, a data memory, a data processor, a controller and an early warning module; the integrated sensing module comprises a millimeter wave radar, a laser radar, a camera and a sensor fusion unit. Early warning is carried out on the vehicles in different conditions in a targeted manner according to the sight conditions of vehicle drivers behind the traffic abnormal point, time is bought for the drivers to carry outcorresponding operation, and pileup collision or secondary collision accidents caused by the collision in the front can be avoided.

    本发明公开了一种对高速公路交通异常点后方车辆进行预警的方法:首先获取道路交通异常的位置,然后判断异常点后方车辆驾驶人视线是否被遮挡,并根据判断结果划分后方车辆的类型;最后针对后方车辆的类型分别进行个性化预警。还公开了实现上述方法的系统,包括分别间隔N米连续安装于高速公路路侧的多个个性化预警装置,每个个性化预警装置包含一体化传感模块、数据存储器、数据处理器、控制器和预警模块;一体化传感模块包含毫米波雷达、激光雷达、摄像机和传感器融合单元。本发明根据交通异常点后方车辆驾驶人的视线情况,针对性的对不同情况的车辆进行预警,为驾驶员做出相应操作争取时间,避免因前方碰撞而引发的连环碰撞或二次碰撞事故。
