The invention relates to a trunk line intersection coordination control method based on track data. The method comprises the following steps: acquiring vehicle operation data of a trunk line intersection, analyzing and obtaining a relationship between a vehicle track and a phase difference, considering an intersection queuing influence factor, establishing a phase difference optimization model taking minimum total delay of coordination traffic flow as a target, obtaining an optimal phase difference scheme, and realizing trunk line intersection coordination control according to the optimal phase difference scheme. Compared with the prior art, the method has the advantages that the cost is low, according to the invention, a trunk line coordination phase difference optimization model is established by using track data. The problems of low precision, insufficient space coverage and the like of fixed detection data in traffic signal control optimization are avoided; t. Te influence of the original queuing conditio
