The invention discloses a multi-path collaborative green wave optimization method for a long-distance trunk road. The method comprises the following steps: S1, acquiring a long-distance trunk road network structure, intersection signal timing parameters and vehicle trajectory data; s2, selecting a key traffic flow path in the long-distance trunk road according to the vehicle trajectory data; s3, taking the intersection as a segmentation point, and establishing a key traffic flow path green wave constraint formula; s4, establishing a multi-path collaborative green wave optimization model by taking the maximization of the bandwidth of the key traffic flow path and the minimization of the parking waiting time as optimization objectives; and S5, solving the multi-path collaborative green wave optimization model, and outputting an optimal coordination control timing scheme. According to the method, long-distance trunk road subarea division and multi-traffic-stream synchronous green wave passing requirements are comprehensively considered, the overall operation efficiency of the long-distance trunk road can be remarkably improved under the conditions of a short period and low saturation, and the parking delay time of running vehicles at the intersection is shortened.
