U.S. Proposes V2V Mandate to Reduce Crashes

December 13, 2016

The U.S. Department of Transportation has proposed mandating vehicle-to-vehicle communication technology on all new light-duty vehicles to enable a wide range of new crash-avoidance applications.

Once fully deployed, these crash-avoidance features "could prevent hundreds of thousands of crashes every year by helping vehicles 'talk' to each other," the department said in a released statement about the proposed rule.

The action reflects the DOT's years-long efforts to accelerate development and deployment of connected vehicle communications and autonomous vehicles. The proposed rule would require vehicle-to-vehicle (V2V) communications devices to exchange information through standardized messaging developed with industry participation.

Automakers would need to fully comply with the mandate within four years after the final rule's implementation.

In a separate move, the department’s Federal Highway Administration plans to soon issue guidelines for vehicle-to-infrastructure (V2I) communications. V2I communications 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," the DOT said.

The department's National Highway Traffic Safety Administration agency estimates that safety applications enabled by V2V and V2I could eliminate or mitigate the severity of up to 80% of crashes not involving impaired drivers. These include crashes occurring at intersections or while changing lanes.

V2V devices would use 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. Using that information, V2V-equipped vehicles could identify risks and provide warnings to drivers to avoid imminent crashes.

Vehicles equipped with 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, according to NHTSA.

Additionally, V2V communications could provide the vehicle and driver with enhanced abilities to address additional crash situations. Examples include assisting the driver in deciding whether it’s safe to pass on a two-lane road or to make a left turn across the path of oncoming traffic. The technology can also determine whether 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 — often in situations in which the driver and on-board sensors alone cannot detect the threat, NHTSA said.

Privacy is also protected in V2V safety transmissions, according to NHTSA.

"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 agency said.

The notice of proposed rulemaking will be open for public comment for 90 days, which carries the issue into the next administration. President-elect Donald Trump's nominee for Transportation secretary is Elaine Chao, who is expected to draw U.S. Senate confirmation without a problem.

"We are carrying the ball as far as we can to realize the potential of transportation technology to save lives," said current 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."

Back in February 2014, Foxx announced his intent to speed efforts to enable V2V communications. That's when he directed NHTSA to begin work on the rulemaking.

    With the obvious benefits to V2V, this is a great long-term goal. But, what about the major source of accidents -- driver distractions? It's like the government and industry are turning a blind eye to this. How hard would it be to eliminate the source of this with deactivating cell phones and interior displays?
