The invention provides a traffic flow detecting and signal lamp intelligent control method for an intersection. In the method, a traffic flow detecting device, a signal lamp operation strategy, a PLCand a signal lamp are involved. The traffic flow detecting device mainly comprises a gantry bridge and a photoelectric switch sensor. According to the method, the traffic flow at the intersection canbe detected in real time; moreover, the cost is low; a signal lamp can be subjected to intelligent control very well by means of real-time data of the traffic flow; through the intelligent control, corresponding subroutines are called after comparing real-time data of the vehicles that travel straight in east and west directions, turn left in the east and west directions, travel straight in southand north directions, and turn left in the south and north directions, so that the time of the signal lamp can be set flexibly in different situations, the problems that the vehicles in lanes are moreor less but the time of the signal lamp is fixed can be solved, moreover, the setting of the time of the signal lamp can be changed along with the change of the numbers of the traffic flow very wellin real time; the control on the signal lamp at the intersection is more intelligent and user-friendly; and the passage efficiency of the vehicles at the intersection can be improved very well.

    本发明提供了一种十字路口车流量检测及信号灯智能控制方法,该方法包括车流量检测装置、信号灯运行策略、PLC和信号灯,车流量检测装置主要由龙门桥架与光电开关传感器构成。该方法对十字路口的车流量能够实现实时检测,而且成本低;通过利用车流量的实时数据很好地对信号灯进行智能控制,智能控制通过把东西直行、东西左转、南北直行和南北左转车辆实时的数据进行比较后调用相应的子程序,能够实现不同情况下信号灯时间的灵活设置,能够解决车道内车辆多或少但信号灯时间固定的问题,而且能够很好地实现信号灯时间的设定随着车流量数目的变化而实时变化,对十字路口信号灯的控制更加智能化、人性化,能够很好地提高十字路口车辆的通行效率。
