The USDOT issued today a Notice of Proposed Rulemaking that 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. V2V devices would use the dedicated short range communications (DSRC) to transmit data, such as location, direction, and speed, to nearby vehicles.
The U.S. Department of Transportation (USDOT) 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.
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. The advancement of the V2V rulemaking complements the Department’s work to accelerate the development and deployment of automated vehicles.
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.
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 days and can be downloaded from NHTSA Notice of Proposed Rulemaking on V2V Communications.
