rule would mandate vehicle-to-vehicle (V2V) communication on light
vehicles, allowing cars to 'talk' to each other to avoid crashes
Citing an enormous potential to reduce crashes on U.S. roadways, the
U.S. Department of Transportation issued a proposed rule today that
would advance the deployment of connected vehicle technologies
throughout the U.S. light vehicle fleet. The Notice of Proposed
Rulemaking would enable vehicle-to-vehicle (V2V) communication
technology on all new light-duty vehicles, enabling a multitude of new
crash-avoidance applications that, once fully deployed, could prevent
hundreds of thousands of crashes every year by helping vehicles “talk”
to each other.
“We are carrying the ball as far as we can to realize the potential of
transportation technology to save lives,” said U.S. Transportation
Secretary Anthony Foxx. “This long promised V2V rule is the next step in
that progression. Once deployed, V2V will provide 360-degree situational
awareness on the road and will help us enhance vehicle safety.”
In February 2014, Secretary Foxx announced the Department would
accelerate its work to enable V2V, directing the Department’s National
Highway Traffic Safety Administration (NHTSA) to begin work on the
rulemaking. NHTSA issued an Advance Notice of Proposed Rulemaking in
August 2014. The advancement of the V2V rulemaking complements the
Department’s work to accelerate the development and deployment of
“Advanced vehicle technologies may well prove to be the silver bullet in
saving lives on our roadways,” said NHTSA Administrator Mark Rosekind.
“V2V and automated vehicle technologies each hold great potential to
make our roads safer, and when combined, their potential is untold.”
The proposed rule announced today would require automakers to include
V2V technologies in all new light-duty vehicles. The rule proposes
requiring V2V devices to “speak the same language” through standardized
messaging developed with industry.
Separately, the Department’s Federal Highway Administration plans to
soon issue guidance for Vehicle-to-Infrastructure (V2I) communications,
which will help transportation planners integrate the technologies to
allow vehicles to “talk” to roadway infrastructure such as traffic
lights, stop signs and work zones to improve mobility, reduce congestion
and improve safety.
NHTSA estimates that safety applications enabled by V2V and V2I could
eliminate or mitigate the severity of up to 80 percent of non-impaired
crashes, including crashes at intersections or while changing lanes.
V2V devices would use the dedicated short range communications (DSRC) to
transmit data, such as location, direction and speed, to nearby
vehicles. That data would be updated and broadcast up to 10 times per
second to nearby vehicles, and using that information, V2V-equipped
vehicles can identify risks and provide warnings to drivers to avoid
imminent crashes. Vehicles that contain automated driving functions—such
as automatic emergency braking and adaptive cruise control—could also
benefit from the use of V2V data to better avoid or reduce the
consequences of crashes.
communications can provide the vehicle and driver with enhanced
abilities to address additional crash situations, including those, for
example, in which a driver needs to decide if it is safe to pass on a
two-lane road (potential head-on collision), make a left turn across the
path of oncoming traffic, or determine if a vehicle approaching an
intersection appears to be on a collision course. In those situations,
V2V communications can detect developing threat situations hundreds of
yards away, and often in situations in which the driver and on-board
sensors alone cannot detect the threat.
Privacy is also protected in V2V safety transmissions. V2V technology
does not involve the exchange of information linked to or, as a
practical matter, linkable to an individual, and the rule would require
extensive privacy and security controls in any V2V devices.
The notice of proposed rulemaking will be open for public comment for 90
