The invention discloses an intersection vehicle trajectory prediction system and method considering traffic flow characteristics. The method comprises the following steps: establishing an intersection vehicle motion trajectory data set; traffic flow characteristic analysis is carried out on the track clusters obtained through clustering, and traffic flow characteristic information under all behavior intentions of the intersection is obtained; acquiring historical time domain trajectory information of the target vehicle and surrounding vehicles; predicting a behavior intention of the target vehicle; obtaining traffic flow characteristic information corresponding to the target vehicle behavior intention; and establishing a long-short-term memory neural network for multi-modal trajectory prediction, and outputting multivariate Gaussian distribution parameters of a final prediction trajectory. According to the invention, by introducing the traffic flow characteristics, multi-modal trajectory prediction which better accords with real traffic distribution can be carried out for different intersections, and the traffic safety of the intersections is effectively improved.
