|The U.S. Department
of Transportation's (DOT) National Highway Traffic Safety Administration
(NHTSA) announced that it will begin taking steps to enable
vehicle-to-vehicle (V2V) communication technology for light vehicles. This
technology would improve safety by allowing vehicles to "talk" to
each other and ultimately avoid many crashes altogether by exchanging basic
safety data, such as speed and position, ten times per second.
indicates that safety applications using V2V technology can address a large
majority of crashes involving two or more motor vehicles. With safety data
such as speed and location flowing from nearby vehicles, vehicles can
identify risks and provide drivers with warnings to avoid other vehicles in
common crash types such as rear-end, lane change, and intersection crashes.
These safety applications have been demonstrated with everyday drivers under
both real-world and controlled test conditions.
applications currently being developed provide warnings to drivers so that
they can prevent imminent collisions, but do not automatically operate any
vehicle systems, such as braking or steering. NHTSA is also considering
future actions on active safety technologies that rely on on-board sensors.
Those technologies are eventually expected to blend with the V2V technology.
NHTSA issued an Interim Statement of Policy in 2013 explaining its approach
to these various streams of innovation. In addition to enhancing safety,
these future applications and technologies could help drivers to conserve
fuel and save time.
|V2V technology does
not involve exchanging or recording personal information or tracking vehicle
movements. The information sent between vehicles does not identify those
vehicles, but merely contains basic safety data. In fact, the system as
contemplated contains several layers of security and privacy protection to
ensure that vehicles can rely on messages sent from other vehicles and that a
vehicle or group of vehicles would be identifiable through defined procedures
only if there is a need to fix a safety problem.
