智慧交通信号控制系统是(shi)基(ji)于交通(tong)大(da)(da)数据的智能自动(dong)化应用系统。通(tong)过系统大(da)(da)数据，对道路(lu)车(che)(che)流(liu)量、人(ren)流(liu)量、路(lu)况态(tai)势进行(xing)(xing)判断(duan)。智慧交通(tong)信号控(kong)制(zhi)(zhi)系统接(jie)入流(liu)量检测器(qi)、排队长度(du)检测器(qi)。速度(du)检测器(qi)等。对系统配时方案(an)进行(xing)(xing)校正和验算。根据实时情况自动(dong)控(kong)制(zhi)(zhi)红绿灯时间，进行(xing)(xing)远程控(kong)制(zhi)(zhi)中心对红绿灯进行(xing)(xing)控(kong)制(zhi)(zhi)，为特种车(che)(che)辆消防车(che)(che)、救护(hu)车(che)(che)、警务(wu)车(che)(che)等车(che)(che)辆进行(xing)(xing)提前规(gui)划(hua)路(lu)线让道处理。

系统可根据各车道(dao)车流(liu)量反馈信息，根据相(xiang)应算法设置各信号灯时间。控(kong)(kong)制(zhi)系统和控(kong)(kong)制(zhi)中(zhong)心相(xiang)连(lian)接，可以实现跨(kua)区域交(jiao)通控(kong)(kong)制(zhi)。在遇到救护车、消防车等突发情(qing)况下(xia)，可以由(you)交(jiao)警通过无线遥控(kong)(kong)临时改变各信号灯的颜色，并且可以对控(kong)(kong)制(zhi)系统软件进行更新，以增强(qiang)其可扩展(zhan)性能(neng)，从(cong)而实现智能(neng)在线控(kong)(kong)制(zhi)。
