The invention discloses an intersection near signal area early warning method and system based on generalized V2X, which belong to the field of road traffic safety. Firstly, pedestrian information and vehicle information of a zebra crossing intersection are obtained; the minimum collision time of possible collision between the vehicle and the pedestrian is obtained according to the pedestrian information and the vehicle information; then according to the minimum collision time, the collision early warning level and the early warning potential field length are determined; and finally, according to the early warning level and the early warning potential field length, early warning reminding is given. The possible collision condition is determined through the pedestrian information and the vehicle information, the reminding can be sent in advance, and the situation that reminding is not timely is avoided; meanwhile, early warning reminding is sent in two modes of a V2X road side communication unit and a zebra crossing lamp; a single early warning mode is avoided; and direct real-time interaction with the vehicle can be realized.
本发明公开了一种基于广义V2X的路口近信号区域预警方法和系统,属于道路交通安全领域;首先,获取斑马线路口的行人信息和车辆信息;根据行人信息和车辆信息得到车辆和行人可能碰撞的最小碰撞时间;然后根据最小碰撞时间确定碰撞的预警等级和预警势场长度;最后根据预警等级和预警势场长度发出预警提醒。本申请通过行人信息和车辆信息确定可能碰撞的情况,能够提前发送提醒,避免提醒不及时;同时通过V2X路侧通信单元和斑马线灯两种方式发送预警提醒;避免了预警方式单一且能够与车辆直接实时交互。
