Researchers from Hunan University developed a Visual Area of Interest (AOI) based multimodal trajectory prediction model that incorporates drivers' visual focus patterns to anticipate vehicle paths and assess risk. The approach integrates a driving intention module and a multimodal trajectory module, enabling more accurate predictions and early risk detection, confirming that visual AOI is an early indicator of driving intention and allowing for risk identification approximately 3 seconds before potential conflicts.
Key insights
- Visual Area of Interest (AOI) provides an early indication of driver intentions, preceding actual steering operations by an average of 0.925 seconds.
- Integrating driver intention derived from visual AOI significantly improves trajectory prediction accuracy, especially over longer time horizons.
- A probabilistic risk assessment framework can identify potential collision risks approximately 3 seconds before conflict with high accuracy and a low false alarm rate.
