BATON ROUGE, La. — If you drive I-12 through Denham Springs, something new is watching the road, and this time, it might actually help. The Louisiana Department of Transportation and Development has put its first AI-powered queue detection system into service on the interstate, a camera-based technology that spots slowdowns earlier than traditional sensors and gives operators more time to respond before backups turn dangerous. DOTD officials called it a first for Louisiana’s road network.
