摘要

This paper presents an analysis of the implementation and performance of a deep learning model based on Recurrent layers and Variational Auto Encoder model (VAE) architecture for prediction of future local trajectory and maneuver. The proposed method uses the encoder part of the VAE to represent the vehicle's surroundings agents behavior in time, taking advantage on the fact that VAE encodes similar situations or states close in the latent space and the generative properties of the VAE decoder, that is used to generate naturalistic driving trajectories. Furthermore, the variance of the predicted trajectory is estimated using the statistical properties of VAE model, increasing it if the input data is noisy or unrealistic and decreasing it if the model is certain about the prediction. The model is trained and evaluated with a public dataset. The results show that the proposed architecture outperforms state of the art methods in trajectory prediction error and provides a variance estimation that depends on input quality.
