The invention relates to the technical field of intelligent traffic management, in particular to an intersection vehicle collision risk early warning method and early warning device.The collision risk early warning method comprises the steps that firstly, under the condition that it is determined that conflicting vehicles exist in the communication range of target vehicles, motion state information of the target vehicles and the conflicting vehicles is obtained; according to the motion state information of the target vehicle and the conflict vehicle, determining whether the target vehicle and the conflict vehicle have a collision risk; under the condition that the collision risk of the target vehicle and the collision vehicle is determined, calculating collision arrival time and risk exposure time of the target vehicle and the collision vehicle, and determining a collision risk level according to the collision arrival time and the risk exposure time; and finally, performing early warning on the target vehicle and/or the conflicting vehicle according to the collision risk level.
本发明涉及智能交通管理技术领域,尤其涉及一种交叉口车辆碰撞风险预警方法和预警装置,其中,碰撞风险预警方法包括,首先在确定目标车辆的通信范围内存在冲突车辆的情况下,获取目标车辆和冲突车辆的运动状态信息;然后根据目标车辆和冲突车辆的运动状态信息,确定目标车辆和冲突车辆是否存在碰撞风险;在确定目标车辆和冲突车辆确定碰撞风险的情况下,计算所述目标车辆和冲突车辆的碰撞到达时间和风险暴露时间,根据碰撞到达时间和风险暴露时间确定碰撞风险等级;最后根据碰撞风险等级对所述目标车辆和/或冲突车辆进行预警。
