The invention discloses a trajectory prediction network model construction method, which comprises the steps that a first decoder module and a second decoder module are configured, the first decoder module is configured to screen out a plurality of alternative prediction trajectories according to true value trajectory data, and the second decoder module is configured to screen out a plurality of alternative prediction trajectories according to the true value trajectory data and the alternative prediction trajectories; and determining a target prediction trajectory. According to the trajectory prediction network model construction method in the embodiment of the invention, at least two groups of decoder modules can be configured when the trajectory prediction network model is constructed, so that the constructed network model is subjected to two-stage data processing according to the multi-modal alternative prediction trajectory generated by the first decoder module; and a second decoder module is further utilized to screen the alternative prediction trajectories again according to the true value trajectory data, so that the prediction trajectory conforming to the road topology is screened out, and the technical purpose of improving the conformity of the prediction trajectory and the road topology is achieved.
