The invention discloses a V2X-based traffic signal lamp control method, a road side unit and a system, and relates to the technical field of V2X. The method comprises the steps that: when a special vehicle enters a first preset range of a traffic signal lamp, a road geometric map is sent to the special vehicle; traffic data sent by the special vehicle based on the road geometric map is received, wherein the traffic data comprises a traffic direction and a traffic lane; when the special vehicle enters a second preset range of the traffic lights, an adjustment instruction is sent according to the traffic direction to adjust a traffic light in the corresponding direction to be in a green light phase and adjust traffic lights in the other directions to be in red light phases; and when the special vehicle is far away from the second preset range of the traffic signal lamp, traffic signal lamp timing is recovered. The signal lights are controlled in real time, it can be ensured that the special vehicle passes through an intersection preferentially, and the passing efficiency and the driving safety are improved.

    本发明公开了一种基于V2X的交通信号灯控制方法、路侧单元及系统,涉及V2X技术领域。其方法包括:当特殊车辆进入交通信号灯第一预设范围时,发送道路几何地图至所述特殊车辆;接收所述特殊车辆基于所述道路几何地图发送的通行数据,所述通行数据包括通行方向和通行车道;当所述特殊车辆进入交通信号灯第二预设范围时,根据所述通行方向发送调整指令将对应方向的交通信号灯调整为绿灯相位,其余方向的交通信号灯调整为红灯相位;当所述特殊车辆远离交通信号灯第二预设范围时,恢复交通信号灯配时。本发明对信号灯进行实时控制,保证特殊车辆优先通过路口,提高通行效率和行车安全。
