The invention discloses an intersection traffic signal dynamic control method and system based on big data. The method comprises the steps that: the traffic flow of each lane of an intersection is detected through an annular coil detector, so as to obtain the traffic flow data corresponding to each lane; and the traffic flow data corresponding to each lane is compared with corresponding reference conduction data. When the traffic flow data exceeds the reference conduction data, the conduction traffic signal of the lane corresponding to the traffic flow data is controlled to be prolonged by a preset time in the next period, and the no-go traffic signals of the other lanes are controlled to be prolonged by the same preset time in the next period. According to the method, the problem that in the prior art, the switching time of traffic lights generally adopts fixed time or fixed time intervals are set in different time periods, so that the red-light 'no-go' time in the direction with large traffic flow at the intersection is too long, the green light time is wasted in the direction with relatively few vehicles, and traffic jam at the intersection is easily caused is solved.

    本发明公开了一种基于大数据的交叉路口交通信号动态控制方法和系统,其中,所述方法包括:利用环型线圈检测器分别对交叉路口各个车道的车流量进行检测,以获得各个车道对应的车流量数据;将各个车道对应的车流量数据与其相对应的基准导通数据进行比较;其中,在所述车流量数据超过所述基准导通数据时,控制其对应的车道的导通交通信号在下一个周期延长预设时间,其余的车道的禁行交通信号在下一个周期延长相同的预设时间。该方法克服现有技术中红绿灯的切换时间普遍采用固定时间或者采用分时段设置固定的时间间隔,容易出现交叉路口的车流量大的方向上红灯禁行时间过长,相对少车的方向却出现绿灯时间空耗的现象,易造成路口交通阻塞问题。
