A large-scale dual-view driving video dataset for understanding the influence of road and traffic conditions on the ego vehicle’s driving behavior in complex (dense, heterogeneous, and unstructured) traffic scenarios. This enables explainable driving decision-making for safe and efficient navigation of intelligent vehicle systems. The dataset contains 3634 annotated driving scenarios in 1140 untrimmed videos. The annotations include 697K important object bounding boxes (9K object tracks), 1-12 objects per driving scenario covering 10 categories, and 19 explanation label categories.
