The invention relates to the field of vehicle trajectory prediction, in particular to a trajectory prediction model optimization method, a trajectory prediction method, a trajectory prediction device and a medium, and the method comprises the steps: obtaining an original data set, carrying out the processing of the original data set, and obtaining a target training set, the original data set comprises vehicle information of vehicles in a target vehicle set in a first duration and corresponding map information; a vehicle prediction model is constructed, the vehicle prediction model is trained based on the target training set, a target prediction model is obtained, the target prediction model comprises an iteration decoder, the iteration decoder is used for iteratively outputting a plurality of future short prediction tracks, and a plurality of future short prediction tracks are obtained. And superposing the plurality of future short prediction trajectories into a plurality of future long prediction trajectories. According to the method, the vehicle trajectory prediction model with a more accurate prediction result of a future long trajectory can be obtained, and the driving safety in practical application is improved.
