Vehicle-to-infrastructure (v2i)

Definition

Vehicle-to-infrastructure (v2i) refers to the communication technology that enables vehicles to interact with road infrastructure, such as traffic signals, signs, and roadside sensors. This interaction allows vehicles to receive real-time information about road conditions, traffic signals, and potential hazards, ultimately enhancing safety, efficiency, and overall traffic management. By establishing a two-way communication link, v2i supports the development of intelligent transportation systems that improve the driving experience and reduce congestion.
