A technology that allows vehicles to wirelessly communicate with each other, connected infrastructure (like traffic signals) and other travelers. The data sent from connected vehicles is anonymous. This data can help drivers avoid crashes and enable transportation agencies to improve mobility and reduce congestion. Connected vehicle systems can involve vehicle-to-vehicle (V2V) or vehicle-to-infrastructure (V2I) communication. Vehicles may also communicate to other travelers, like pedestrians or bicyclists, sometimes referred to as vehicle-to-pedestrian (V2P) communication. The combined capability of these modes is often referred to as vehicle-to-everything (V2X). Connected vehicles use DSRC or C-V2X communication technologies.
