RedLight-VLA: Models for traffic-rule grounding and behavioral emphasis in driving policies

Behavior-cloned Vision-Language-Action (VLA) driving policies struggle with rare rule-governed maneuvers at signalized intersections. Braking and launching examples contribute little to averaged trajectory loss, while fused representations lack explicit supervision for the governing traffic-light and stop-line state. W...

Multi-Modal Traffic Sign Detection with Semantic Attributes for Autonomous Driving

A dual motion-model tracker that explicitly accounts for non-linear perspective transformations during vehicle approach is introduced, substantially improving temporal consistency over linear motion assumptions, and a semantic attribute classification pipeline that estimates occlusion level, readability, sign embeddedn...
