The embodiment of the invention discloses a road information processing method, a road side unit, a vehicle-mounted device and a storage medium. The road information processing method comprises the steps: acquiring static map data used for representing geographic information of a set area; obtaining dynamic data used for representing real-time dynamic conditions of the road, wherein the dynamic data comprises at least one of traffic management information used for representing driving management related to the road, danger warning information used for representing emergency conditions of the road and traffic signal lamp information used for representing the traffic state of the intersection; generating dynamic message frames from the static map data and the dynamic data according to data types and corresponding priorities; and broadcasting the dynamic message frame through a broadcast channel, so as to enable a vehicle-mounted device within the communication range of the broadcast channel to receive the dynamic message frame. Therefore, the vehicle-mounted device can obtain dynamic relevant data of the road in time, the real-time early warning requirement is met, and the traffic safety and the traffic efficiency are improved.
本发明实施例公开了一种道路信息处理方法、路侧单元、车载装置及存储介质,该道路信息处理方法包括:获取用于表征设定区域的地理信息的静态地图数据;获取用于表征道路实时动态的动态数据,所述动态数据包括:用于表征道路上行驶管理相关的交通管理消息、用于表征道路紧急状况的危险警告信息及用于表征交叉路口通行状态的交通信号灯信息中的至少一种;将所述静态地图数据和所述动态数据根据数据类型和对应的优先级生成动态消息帧;将所述动态消息帧经广播信道广播,以供所述广播信道通信范围内的车载装置接收所述动态消息帧。便于车载装置及时获得路道动态相关的数据,满足实时预警需求,从而提高交通安全和通行效率。
