The invention discloses a special vehicle intersection priority passing traffic control system, which is based on V2X messages and comprises the following steps: a V2X message receiving module receives V2X messages of all equipment; the V2X message filtering module only screens out the BSM messages of all vehicles driving to the intersection from the V2X messages, and filters out the V2X messages of the special vehicles; the V2X message processing module extracts the position, the speed, the course angle and the driving intention of the vehicle with the priority right, calculates the time interval parameters of the vehicle arriving at and passing through the intersection according to the map data, and calculates the expected phase state of the signal lamp in the time interval; the traffic signal lamp control module controls the traffic signal lamp to output passable phases in the time interval parameters according to the time interval parameters when the vehicle arrives at and passes through the intersection. According to the invention, the on-duty special vehicle cannot be interfered by the vehicles on the transverse lane when passing through the intersection in real time preferentially, so that the running speed of the special vehicle is improved, and the accident occurrence rate is reduced.
本发明公开了一种特种车辆路口优先通行交通控制系统,其基于V2X消息,包括:V2X消息接收模块接收所有设备的V2X消息;V2X消息过滤模块从V2X消息中只筛选出驶向本路口的所有车辆的BSM消息,过滤出特种车辆的V2X消息;V2X消息处理模块对于具有优先通行权的车辆,提取车辆位置、速度、航向角和行驶意图,并根据地图数据计算出该车辆到达及通过交叉路口的时间区间参数,计算出信号灯在上述时间区间的预期相位状态;交通信号灯控制模块根据车辆到达及通过交叉路口的时间区间参数,控制交通信号灯在上述时间区间参数输出可通行的相位。本发明能实现执勤特种车辆实时优先通过交叉路口时,不会遭到横向车道车辆干扰,从而提高特种车辆行驶速度,降低意外发生率。
