Preventing unsafe vehicle trajectory predictions

This paper presents a two-stage model for predicting future vehicle trajectories that ensures safety and feasibility. A refinement layer first generates physically possible trajectories using map data and vehicle kinematics. Then a neural network learns trajectory probabilities conditioned on the refined set, incorporating cross-attention between trajectories and goal lanes. This method achieves state-of-the-art performance while eliminating almost all unsafe, off-road predictions.
