Connected roadways and intersections primarily enable the connectivity for traffic signal controllers, video surveillance, and digital signage. These technologies are integrated to manage traffic flow more efficiently, enhance road safety, and provide real-time information to drivers and pedestrians. This integration supports smart city initiatives by improving traffic management, reducing congestion, and increasing safety and information dissemination at roadways and intersections.
