Method, system and device for controlling phase duration of traffic light, medium and product

The invention relates to the technical field of information, and provides a method, system and device for controlling the phase duration of traffic lights, a medium and a product. The method for controlling the phase duration of the traffic light is applied to an edge device, the edge device is in communication connection with the traffic light, and the method comprises the following steps: in response to a preset position of a bus arriving at a current intersection, obtaining the crowdedness degree of the current intersection in each direction, the traffic light state in each direction and the expected driving direction of the bus; based on the crowding degree of each direction, the traffic light state of each direction and the expected driving direction of the bus, the green light phase duration of each direction of the current intersection is corrected, and the corrected green light phase duration of each direction is obtained; and controlling traffic lights of the current intersection based on the correct
