- Abstract:
-
Predicting trajectories of surrounding agents is critical to realize the decision-making planning of autonomous driving behaviors. Facing the difficulties brought by complex vehicle interaction and multimodal driving intention, this paper proposes a trajectory prediction method based on vehicle multi-agent interaction behavior modeling. The method uses conditional variational autoencoder to generate multi-modal results of the trajectory endpoints. By combination with the self-attention mechanism and multi-head attention mechanism, the influence of group interaction between vehicles is captured. Finally, the inverse reinforcement learning is used to output the optimal decision of multi-modal trajectory, realizing synchronous prediction of multi-agent trajectory. An experiment has been carried out on the NGSIM, which is a real-world trajectory prediction dataset on the highway traffic scene. The results prove effectiveness of the model, and the prediction effect is better than existing methods as a whole.
