V2I, or Vehicle-to-Infrastructure, refers to a communication system that allows vehicles to exchange information with road infrastructure, such as traffic lights, road signs, and toll booths. This technology aims to improve traffic flow, enhance safety, and reduce congestion by providing real-time data to drivers and vehicles. By utilizing V2I systems, vehicles can receive alerts about traffic conditions, road hazards, and upcoming traffic signals. This information helps drivers make informed decisions, leading to smoother journeys and potentially fewer accidents. Overall, V2I plays a crucial role in the development of smart transportation systems.
