Vehicle-to-Infrastructure (V2I) communication involves personal, commercial, transit and emergency vehicles, even trains and pedestrians, communicating their location and status with roadside equipment mounted on street lights or traffic signals.

Real-time traffic data provided by connected vehicles can help make transit more reliable by enabling traffic signals to give priority to buses.

Vehicles, pedestrians and roadside equipment can share information as often as 10 times per second, transmitting and receiving messages about vehicle behavior and roadway conditions.
