NHTSA releases advanced notice of proposed rulemaking on V2V, supporting research report
18 August 2014
The US Department of Transportation’s (DOT) National Highway Traffic Safety Administration (NHTSA) has released an advance notice of proposed rulemaking (ANPRM) and a supporting comprehensive research report on vehicle-to-vehicle (V2V) communications technology. NHTSA is working to deliver a Notice of Proposed Rulemaking by 2016.
The report will include analysis of the Department’s research findings in several key areas including technical feasibility, privacy and security, and preliminary estimates on costs and safety benefits, while the ANPRM seeks public input on these findings to support the Department’s regulatory work to eventually require V2V devices in new light vehicles.
The report includes preliminary estimates of safety benefits that show two safety applications—Left Turn Assist (LTA) and Intersection Movement Assist (IMA)—could prevent up to 592,000 crashes and save 1,083 lives saved per year.
Put another way, V2V technology could help drivers avoid more than half of these types of crashes that would otherwise occur by providing advance warning. LTA warns drivers not to turn left in front of another vehicle traveling in the opposite direction and IMA warns them if it is not safe to enter an intersection due to a high probability of colliding with one or more vehicles. Additional applications could also help drivers avoid imminent danger through forward collision, blind spot, do not pass, and stop light/stop sign warnings.
V2V technology has the potential to be fused with existing vehicle safety features to further improve the effectiveness of many crash avoidance safety systems currently being developed and implemented in the vehicle fleet and serve as a building block for a driverless vehicle.
Vehicles equipped with V2V technology could also enable the development of a wide range of mobility and environmental benefits based on vehicle-to-infrastructure applications and other V2V applications that can enhance traffic flow in many ways. V2V technology does not involve collecting or exchanging personal information or tracking drivers or their vehicles, NHTSA said.
The information sent between vehicles does not identify those vehicles, but merely contains basic safety data. The system as contemplated contains several layers of security and privacy protection to ensure that vehicles can rely on messages sent from other vehicles.
