The invention relates to a traffic signal lamp display method based on vehicle-road cooperation, a vehicle-mounted unit, a road side unit and a system. The method comprises the following steps: enabling a dedicated operation vehicle OBU to receive signal lamp state information transmitted by an RSU in real time; wherein the signal lamp state information is obtained by the RSU from the signal lampcontrol system in a direct communication mode or a non-direct communication mode; the special operation vehicle OBU pushes the signal lamp state information to an electronic display screen of the special operation vehicle for display; wherein the electronic display screen is arranged outside the special operation vehicle. By implementing the technical scheme of the invention, the electronic display screen behind the tail of the special operating vehicle can display the state of the front traffic light, so that a driver of the rear vehicle can accurately judge the next driving action under theshielding condition of the special operating vehicle, traffic accidents are avoided, and the life safety of the driver is guaranteed.

    本发明涉及了基于车路协同的交通信号灯显示方法、车载单元、路侧单元及系统,其中,该方法包括:专用运营车辆OBU实时接收RSU发送的信号灯状态信息;其中信号灯状态信息是RSU通过直接通讯模式或者非直接通讯模式从信号灯控制系统获取的;专用运营车辆OBU将信号灯状态信息推送至专用运营车辆的电子显示屏进行显示;其中电子显示屏设置在专用运营车辆的外部。实施本发明的技术方案,可实现专用运营车辆车尾后的电子显示屏显示前方红绿灯状态,以便后车驾驶员在专用运营车辆遮挡情况下准确判断下一步驾驶动作,避免交通事故的发生,保障驾驶员的生命安全。
