Coordination control method, device and equipment of main road and medium

The embodiment of the invention provides a coordination control method, device and equipment for arterial roads and a medium, and relates to the technical field of traffic control, and the method comprises the steps: obtaining intersection parameters and road control parameters of a plurality of intersected arterial roads; the method comprises the steps of determining combination schemes of release modes of different signal periods and different target intersections, calculating the main line bandwidth of each main line under each combination scheme by using the intersection parameters and the road control parameters for each combination scheme, and determining the comprehensive bandwidth corresponding to the combination scheme according to the main line bandwidth of each main line, the main line bandwidth comprises a main line green wave bandwidth or a main line red wave bandwidth; and determining a combination scheme of which the corresponding comprehensive bandwidth meets a preset traffic control condition
