Connected Vehicles (V2X, or vehicle-to-everything) technology combines two elements: communication between vehicles and infrastructure (V2I, or vehicle-to-infrastructure) and communication between vehicles (V2V, or vehicle-to-vehicle). Together, those elements form the basis of Cooperative Intelligent Transportation Systems (C-ITS).
V2X is a standardized two-way dedicated short range communication (DSRC) technology. The communication technology is based on broadcasting messages instead of point-to-point communication.
The standards for the communication technology are defined in the ETSI ITS-G5 for Europe and IEEE WAVE® for the United States.
