Joint detection and state recognition of traffic lights and signs through a lightweight hybrid CNN–transformer framework

Accurate detection of traffic lights and signs is a critical task for safe autonomous vehicle systems (AVS). Despite advances in deep learning, most methods treat traffic light detection, traffic sign detection, and state recognition as separate tasks, while CNN-based models lack global context modeling and transformer...
