The invention provides a traffic light control system and method for a special vehicle to pass preferentially. The control system comprises a special vehicle identification module, a road junction module, a calculation module and a traffic light module. The traffic light control method comprises the following steps that (1) when the special vehicle identification module identifies a special vehicle, the control module adjusts traffic lights except the direction of the special vehicle to red lights and adjusts traffic lights in the direction of the special vehicle to green lights; (2) the special vehicle identification module sends information to a road junction module, and the road junction module sends speed and position information to a calculation module; (3) the calculation module calculates the distance between the tail of the special vehicle and the traffic light and the duration of the special vehicle passing through the traffic light and sends the distance and the duration to a control module, and the control module adjusts the duration into the duration of the traffic light in the direction where the special vehicle is located; and (4) after the special vehicle passes, the traffic light recovers to the original state. The technical problem that the special vehicle delays working due to traffic reasons in the prior art is solved.

    本发明提供了一种特种车辆优先通过的红绿灯控制系统及控制方法,该控制系统包括特种车辆识别模块、道路口模块、计算模块和红绿灯模块;红绿灯控制方法包括:(1)特种车辆识别模块识别到特种车辆时,控制模块将特种车辆所在方向以外的红绿灯调成红灯,将特种车辆所在方向的红绿灯调成绿灯;(2)特种车辆识别模块将信息发送给道路口模块,道路口模块将速度和位置信息发给计算模块;(3)计算模块计算出特种车辆车尾距离红绿灯的距离,以及特种车辆通过红绿灯的时长,将距离和时长发送给控制模块,控制模块将时长调成特种车辆所在方向的红绿灯时长;(4)特种车辆通过后,红绿灯恢复成原状态。本发明解决了现有技术中由于交通原因导致特种车辆延误工作的技术难题。
