Analysis

This paper addresses a critical challenge in autonomous driving: accurately predicting lane-change intentions. The proposed TPI-AI framework combines deep learning with physics-based features to improve prediction accuracy, especially in scenarios with class imbalance and across different highway environments. The use of a hybrid approach, incorporating both learned temporal representations and physics-informed features, is a key contribution. The evaluation on two large-scale datasets and the focus on practical prediction horizons (1-3 seconds) further strengthen the paper's relevance.
