A multi-stage framework integrating YOLOv8 detection, OC-SORT tracking, dynamic CROI filtering, and ST-GAT prediction enables accurate real-time traffic-conflict prediction at signalized intersections to enhance safety and mitigate accident risks.
Researchers built a multi-stage video-based framework for signalized intersections that combines YOLOv8 detection with OC-SORT tracking to extract vehicle trajectories, uses a dynamic scaling Conflict Region of Interest to reduce data volume, and predicts conflicts with a Spatio-Temporal Graph Attention Network followed by causal forest interpretation. Tested on field video from an intersection in Nanning, China, the ST-GAT model outperformed existing deep learning architectures on training and testing sets.
