The invention relates to a road signal lamp early warning method and device and a medium. The method comprises the steps of receiving position information and course information of a target vehicle sent by a vehicle-mounted terminal; determining the distance between the target vehicle and a front intersection based on the position information and the course information of the target vehicle and preset roadside map information; determining signal lamp information corresponding to a lane of the target vehicle based on the position information of the target vehicle, the roadside map information and preset roadside signal lamp information; and sending the distance between the target vehicle and the front intersection and the signal lamp information corresponding to the lane of the target vehicle to the vehicle-mounted terminal, thereby enabling the vehicle-mounted terminal to judge whether to execute road signal lamp early warning or not based on the vehicle speed of the target vehicle, the distance between the target vehicle and the front intersection and the signal lamp information corresponding to the lane of the target vehicle. According to the invention, the data communication traffic of vehicle-road interaction can be minimized, and the efficiency of vehicle-road interaction data transmission is improved.

    本发明涉及一种道路信号灯预警方法、装置及介质,所述方法包括:接收车载终端发送的目标车辆的位置信息和航向信息;基于所述目标车辆的位置信息、航向信息和预设的路侧地图信息确定所述目标车辆距离前方路口的距离;基于所述目标车辆的位置信息、所述路侧地图信息和预设的路侧信号灯信息确定与所述目标车辆的车道对应的信号灯信息;将所述目标车辆距离前方路口的距离和与所述目标车辆的车道对应的信号灯信息发送给所述车载终端,以使所述车载终端基于所述目标车辆的车速、目标车辆距离前方路口的距离和与所述目标车辆的车道对应的信号灯信息判断是否执行道路信号灯预警。实施本发明,可最小化车路交互的数据通信量,提高车路交互数据传输的效率。
