The invention provides an intersection collision early warning test method and system, electronic equipment and a storage medium, and the method comprises the steps: analyzing a motion pre-collision track of each traffic participant for intersection collision early warning, and constructing a collision scene; constructing a plurality of subdivided scenes according to the plurality of collision factors in the collision scene, and obtaining a pre-collision trajectory algorithm corresponding to the plurality of subdivided scenes; acquiring a preset value range of each collision factor; and according to the pre-collision trajectory algorithm and the preset value range of each collision factor, adjusting the test parameters in the plurality of subdivided scenes to complete the intersection collision early warning test. Through carrying out collision trajectory analysis on each traffic participant in the intersection, a possible collision scene is comprehensively analyzed, test parameters are adjusted through a plurality of collision factors and a trajectory algorithm of a subdivided scene, and the vehicle collision scene at the intersection is more reasonably and comprehensively tested. And the safety of the intersection is greatly improved.
