Vehicle-to-everything or V2X technology enables vehicles to communicate to their surroundings including traffic signals, other vehicles, infrastructure, bicyclists and pedestrians. V2X leverages wireless protocols such as dedicated short range communication (DSRC) or cellular V2X (C-V2X) to enable this communication.
Vehicle-to-everything technology has the opportunity to improve traffic flow and enhance road safety, by enabling traffic signals and vehicles to exchange information, such as signal-time and -phase, vehicle position and speed. Sharing this information with non-line-of-sight vehicles can avoid collisions. The National Highway Transportation Safety Administration estimates that by implementing just two V2X applications we can prevent over 1000 deaths per year.
