Vehicle-to-infrastructure (V2I) is a wireless data exchange system where vehicles communicate with road equipment like traffic lights, toll booths, and speed cameras. It uses dedicated short-range communications (DSRC) or cellular networks to optimize traffic flow, warn drivers of upcoming hazards, and automate toll collection without slowing down.
