摘　　要：特种车辆执行任务时在道路上有优先通过的权利,但是经常发生在红绿灯路口社会车辆因为害怕闯红灯而不让行特种车辆的事件,因此十分有必要设计一种特种车辆路口优先系统。提出了一种利用特种车辆发出的警报声来对其进行优先放行的方法,通过在路口安装麦克风阵列,识别出特种车辆的到来,并准确定位到特种车辆所在的车道,同时向信号机发出指令,使信号机放行特种车辆所在车道,从而保证特种车辆的优先通行,并且不会对路口的社会车辆产生太大的影响。Special vehicles have the priority to pass on the road when performing their tasks.However,it often happens that social vehicles do not give way to special vehicles because they are afraid of running red lights.Therefore,it is very necessary to design a special vehicle intersection priority system.This paper proposes a method of using the warning sound of special vehicles to give priority to them.By installing a microphone array at the intersection,it can recognize the arrival of special vehicles,and accurately locate the lane where the special vehicles are located,and send the signal to the signal machine at the same time,and command signal to release the lane where special vehicles,special vehicles to ensure priority access,and it will not have much impact on society of the vehicle crossing.
