Abstract:

A vehicle cut?in intention prediction model based on Residual BiLSTM network is proposed in this paper according to the real road features in China. The cut?in features are extracted from the trajectory information of the cut?in vehicle and its interaction information with ego vehicle, and the softmax function is used to calculate the cut?in intention, e.i. the probability of left lane keeping, left lane cut?in, right lane cut?in or right lane keeping respectively. Finally, the prediction model is trained and tested with the naturalistic driving data set on the complex roads in China. The results show that the Residual BiLSTM model proposed has obvious advantages in cut?in intention prediction, with an accuracy 8.2 percentage points higher than that of LSTM model, and can predict the vehicle cut?in intention earlier, being of great significance in enhancing the decision?making and planning ability and safety of autonomous vehicles.
