The invention discloses a method for distinguishing the influence of vehicle behaviors on traffic safety during traffic oscillation. The method comprises the following steps: setting a controllable vehicle, a mitigation road section, a control lane and an open lane; a plurality of cameras are arranged along the relieving road section; applying a target mitigation speed to the controllable vehicle in the control lane, the target mitigation speed being based on the traffic state of the open lane; acquiring a video image of the controllable vehicle so as to obtain a driving behavior of a driver; analyzing the obtained data of the driving behavior of the driver through an artificial potential field method to obtain a repulsive force field gradient and a virtual force of the behavior of the driver; the gradient of the repulsive force field of the driver behavior and the virtual force are combined with an adaptive unscented Kalman filtering method to establish a motion equation fused with the driver behavior, and prediction of the vehicle motion state is achieved; according to the invention, traffic congestion can be solved flexibly and traffic oscillation on a road comprising a plurality of lanes can be stabilized in various traffic environments; according to the method, the accuracy and robustness of moving vehicle state prediction are greatly improved.
