The invention discloses an intersection lane attribute configuration method, an early warning method, a vehicle-mounted unit and a vehicle-road cooperation system, and relates to the technical field of Internet of Vehicles. The intersection lane attribute configuration method comprises the following steps: acquiring a map message corresponding to an intersection, wherein the map message comprises lane attribute information of each lane of the intersection; and adding a left-turn waiting area identification attribute in the lane attribute information of each lane, wherein the left-turn waiting area identification attribute is used for representing whether the lane is a waiting area lane or not. According to the method, the identification attribute of the left-turn waiting area is added in the map message, so that the map message has the description of the to-be-turned area, the description of the map message to the intersection is more practical, the vehicle-mounted unit can conveniently identify the to-be-turned area, and the accuracy of early warning of vehicles on a left-turn lane or the left-turn waiting area is further improved.

    本发明公开了一种路口车道属性配置、预警方法、车载单元及车路协同系统,涉及车联网技术领域。该路口车道属性配置方法包括获取路口对应的地图消息,所述地图消息包括所述路口的各个车道的车道属性信息;在所述各个车道的车道属性信息中添加左转待转区标识属性,所述左转待转区标识属性用于表征车道是否为待转区车道。该方法在地图消息中添加左转待转区标识属性,使得地图消息具有了对待转区的描述,地图消息对交叉路口的描述更贴合实际,便于车载单元识别待转区,进而提高对左转车道或左转待转区车辆预警的准确性。
