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 communication's lifesaving potential into reality.
What is V2V communication?
NHTSA is dedicated to advancing the lifesaving potential of vehicle technologies
In an effort to seriously reduce the potential for a vehicle crash on America’s roadways, the Department of Transportation issued a Notice of Proposed Rulemaking (NPRM) that would enable V2V communication technology on all new light-duty vehicles. The V2V NPRM accomplished the following:
- Required vehicles to transmit and receive standardized messages;
- Proposed a communication platform only;
- Left application/implementation to market;
- Provided for alternative technologies; and
- Left open to any capable, testable technology.
The NPRM was published in January 2017 with a 90-day comment period, during which NHTSA received 450 comments. Key comment topics included the following:
- Technology Strategy;
- Implementation Timing;
- Detailed Technical Information;
- Cost Estimates;
- Potential Health Effects; and
- Privacy and Security.
