The invention relates to the field of road traffic facilities, and discloses a special vehicle automatic green wave traffic signal control method. The special vehicle automatic green wave traffic signal control system communicates with the central server through a wireless positioning module on the special vehicle, positions the position of the special vehicle and judges the passing direction of the special vehicle; when the special vehicle reaches a certain distance (such as 300m) in front of the intersection, the central server sends an instruction to the intersection annunciator; the annunciator lights up a green light for the pre-passing direction of the special vehicle through an optimization algorithm, notifies an LED screen on the side edge of the signal lamp to issue warning information, and reminds the waiting vehicle that the special vehicle is about to arrive, please quickly pass and give way in advance. Therefore, motor vehicles waiting for passing in the direction are emptied in advance, and a green channel is opened up for passing of special vehicles. And the annunciator at the next intersection repeats the same steps, so that the special vehicle can be unimpeded whengoing down from the road, and a large amount of precious time is gained for rescue and relief work and rescue and injury protection.

    本发明涉及道路交通设施领域,且公开了一种特种车辆自动绿波交通信号控制方法。特种车辆自动绿波交通信号控系统通过特种车辆上的无线定位模块与中央服务器进行通信,定位特种车辆位置以及判断特种车辆的通行方向,当特种车辆达到路口前一定距离(例如300米)时,中央服务器向此路口信号机发送指令,信号机通过优化算法,为特种车辆预通行方向亮绿灯,通知信号灯侧边的LED屏发布警示信息,提醒等候车辆有特种车辆即将到来,请快速通过,提前让道。从而提前清空此方向等候通行的机动车,为特种车辆通行开辟了一条绿色通道。下一路口的信号机重复同样的步骤,这样一路下来,特种车辆能够畅通无阻,从而为抢险救灾,救死护伤赢得大量的宝贵时间。
