What are Connected Smart Roads and Highways?
Connected Smart Roads and Highways refer to transportation infrastructure embedded with digital technology that allows real-time communication between vehicles (V2V), vehicles and infrastructure (V2I), and infrastructure to central systems. These roads use sensors, IoT (Internet of Things) devices, AI (Artificial Intelligence), and big data analytics to monitor, predict, and manage traffic flow, road conditions, and environmental impacts.
Unlike traditional roads, which are passive, smart roads are proactive systems that interact dynamically with the environment and users. They are a critical element of Intelligent Transportation Systems (ITS) and are designed to support autonomous vehicles, enhance road safety, reduce congestion, and optimize travel experiences.
Key Technologies Behind Smart Roads
The development of connected smart roads relies on several cutting-edge technologies:
