The invention discloses an intelligent network connection mixed traffic flow intersection signal collaborative optimization method and system. The method comprises the following steps: carrying out high-precision acquisition on traffic state information; optimizing the trajectory of the intelligent vehicle based on initial information control; and performing optimization based on the optimized signal control of the intelligent vehicle track. In this way, the defects that in a mixed traffic mode, the permeability of the intelligent vehicles is low, a large number of intelligent vehicles follow the manual driving vehicles, only single intelligent vehicles are controlled, the multi-vehicle following state is not considered, and the optimization effect is limited are overcome. Meanwhile, by adopting a track and signal collaborative optimization mode, the operation efficiency of the intersection is further improved, it is guaranteed that a data source is more accurate and microcosmic, and a control strategy is more reasonable and effective.
