Vehicle-to-Infrastructure (V2I) refers to the communication system that allows vehicles to exchange information with road infrastructure, such as traffic lights, road signs, and sensors. This technology aims to improve traffic flow, enhance safety, and reduce congestion by providing real-time data to drivers and automated systems. Through V2I, vehicles can receive updates about traffic conditions, road hazards, and optimal routes. This information helps drivers make informed decisions and allows for better coordination between vehicles and infrastructure, ultimately leading to a more efficient transportation system and improved road safety.
