The invention relates to the technical field of traffic safety, in particular to a high-speed ramp shunting area collision early warning method based on a roadside laser radar, and the method comprises the steps: enabling detected, calculated and processed coordinates to correspond to the plane positions of a real-time converging area and a ramp; the accuracy of the positions of the vehicles and the perception of the relative positions of the vehicles in the confluence area and the ramps are improved, which plays a key role in collision early warning of multiple vehicles in the confluence area, and potential collision occurrence points can be obtained through big data analysis so as to make early warning prompts in advance.

    本发明涉及交通安全技术领域,具体地说是一种基于路侧激光雷达的高速匝道分流区碰撞预警方法,本发明通过将探测计算处理过的坐标与实时合流区和匝道的平面位置做出对应,提高了对于车辆位置的准确性以及车辆在合流区和匝道上的相对于位置的感知,这对于在合流区内的多辆汽车的碰撞预警起到了关键的作用,也可以通过大数据分析得出潜在的碰撞发生点从而提前做出预警提示。
