The embodiment of the invention discloses an intelligent traffic light system. The system comprises an collection processing module used for acquiring a traffic flow image, a controller module, an execution module and a scheduling module. The adjusting method comprises the steps that the traffic flow and the vehicle speed within the unit distance between every two adjacent traffic light intersections are obtained, and then the road congestion situation within an autonomously-specified timestamp is obtained through analysis; calculating the ideal time between two adjacent traffic lights according to the road congestion condition in the timestamp, and obtaining the difference between the ideal time and the traffic light standard time planned by the urban traffic; the standard time of trafficlight circulation is progressively increased and decreased in seconds to approach the ideal time of traffic light circulation; Meanwhile, the obtained traffic flow and vehicle speed analysis condition within the unit distance between two adjacent traffic light intersections is used as the standard for judging whether the stopping standard time is close to the ideal time or not, so that the urbanroad utilization rate is effectively improved.
本发明实施例公开了一种智能交通灯系统,包括用于采集车流量图像的采集处理模块、控制器模块、执行模块和调度模块;其调节方法,包括获取在相邻两个红绿灯路口之间的单位距离内的车流量和车速,进而分析获得自主规定的时间戳内道路拥堵情况;根据时间戳内的道路拥堵情况计算相邻两个红绿灯之间的理想时间,同时与城市交通规划的红绿灯标准时间进行取差;以秒为单位进行红绿灯循环的标准时间的递增和递减来接近红绿灯循环的理想时间,同时以获取在相邻两个红绿灯路口之间的单位距离内的车流量和车速分析情况作为是否停止标准时间靠近理想时间的标准,有效的提高城市道路利用率。
