Intelligent traffic light system and adjusting method

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 distanc
