The U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA)’s Notice of Proposed Rulemaking (NPRM) consists of a proposal to mandate vehicle-to-vehicle (V2V) technology in all new light vehicles by utilizing the radio transmission protocols and spectrum bandwidth collectively known as dedicated short-range communications (DSRC). The agency is proposing to require that all V2V devices must “speak the same language” through a standard technology. The agency is also proposing that privacy and security measures are employed in any V2V device. The comment period ended on April 12, 2017.
V2V is a crash avoidance technology that relies on communication of information between nearby vehicles to warn drivers about potentially dangerous situations that could lead to crashes. For example, V2V could help warn a driver that a vehicle ahead is braking and they need to slow down, or let a driver know that it is not safe to proceed through an intersection because another car, unseen by the driver, is quickly approaching.
The NPRM followed NHTSA’s previously issued advance notice of proposed rulemaking (ANPRM) and research report, “Vehicle-to-Vehicle Communications: Readiness of V2V Technology for Application,” in August 2014, and directly supports NHTSA’s announcement on February 3, 2014, that the Department would work on a regulatory proposal to require V2V devices in new vehicles.
The agency specifically requested comments on the interplay between V2V and autonomous technologies. Industry stakeholders agree that they would utilize V2V information to enhance their systems, and even further, it would not be possible to optimize the benefits of automated vehicles without V2V.
NHTSA hosted public meetings on April 9 and April 27, 2017 seeking input on operational guidelines for the safe deployment of automated vehicles (AV), including V2V technology.
Full details and links to supporting documents are available at NHTSA’s V2V Communications website, including the V2V Communications NPRM Fact Sheet, which was adapted for this summary.
