Vehicle to Vehicle Communications
Overview
Vehicle-to-vehicle (V2V) communication’s ability to wirelessly exchange information about the speed and position of surrounding vehicles shows great promise in helping to avoid crashes, ease traffic congestion and improve the environment. But the greatest benefits can only be achieved when all vehicles can communicate with each other. That’s why NHTSA has been working with the automotive industry and academic institutions for more than a decade to advance V2V’s lifesaving potential into reality.
Basics
How V2V works
NHTSA is committed to improving safety and mobility on our nation's roadways. As we look ahead to the next stage of roadway safety in America, vehicle-to-vehicle (V2V) communication technology shows great promise in transforming the way Americans travel. Using V2V technology, vehicles ranging from cars to trucks and buses to trains could one day be able to communicate important safety and mobility information to one another that can help save lives, prevent injuries, ease traffic congestion, and improve the environment.
