WASHINGTON
(AP)—The future of automotive safety is coming this summer to the U.S.:
Cars that to talk to each other and warn drivers of impending
collisions.
The
U.S. government is launching a yearlong, real-world test involving
nearly 3,000 cars, trucks and buses using volunteer drivers in Ann
Arbor, Michigan.
The
vehicles will be equipped to continuously communicate over wireless
networks, exchanging information on location, direction and speed 10
times a second with other similarly equipped cars within about 1,000
feet (300 meters). A computer analyzes the information and issues danger
warnings to drivers, often before they can see the other vehicle.
Called
vehicle-to-vehicle communication, or V2V, more advanced versions of the
systems can take control of a car to prevent an accident by applying
brakes when the driver reacts too slowly to a warning.
V2V
“is our next evolutionary step … to make sure the crash never happens
in the first place, which is, frankly, the best safety scenario we can
all hope for,” said David Strickland, administrator of the National
Highway Traffic Safety Administration.
V2V
technology holds the potential to help in most crashes that aren’t
alcohol or drug related, Strickland said. But a lot will depend on how
drivers respond to the warnings, and that’s one reason for the Ann Arbor
test. Overall, more than 32,000 people were killed in traffic accidents
in the United States last year.
In
addition to warning of cars running red lights or stop signs,
“connected cars” can let drivers know if they don’t have time to make a
left turn because of oncoming traffic. When driving on a two-lane road,
the systems warn when passing is unsafe because of oncoming cars — even
vehicles around a curve that the driver can’t see yet.
In
a line of heavy traffic, the systems issue an alert if a car several
vehicles ahead brakes hard even before the vehicle directly in front
brakes. And the systems alert drivers when they’re at risk of
rear-ending a slower-moving car.
It’s
also possible for connected cars to exchange information with traffic
lights, signs and roadways if states and communities decide to equip
their transportation infrastructure with similar technology. The
information would be relayed to traffic management centers, tipping them
off to congestion, accidents or obstructions. If cars are reported to
be swerving in one spot on a roadway, for example, that could indicate a
large pothole or obstruction. The constant stream of
vehicle-to-infrastructure, or V2I, information could give traffic
managers a better picture of traffic flows than they have today,
enabling better timing of traffic signals to keep cars moving, for
example. Correspondingly, cars could receive warnings on traffic tie-ups
ahead and rerouting directions.
NHTSA
has been working on the technology for the past decade along with eight
automakers: Ford, General Motors, Honda, Hyundai-Kia, Mercedes-Benz,
Nissan, Toyota and Volkswagen.
“We
think this is really the future of transportation safety, and it’s
going to make a huge difference in the way we live our lives,” said
Scott Belcher, president of the Intelligent Transportation Society of
America, which promotes technology solutions to transportation problems.
The
technology is already available, said Rob Strassburger, vice president
for safety of the Alliance of Automobile Manufacturers. He said what’s
needed is for the government to set standards so that all automakers use
compatible technology.
Some
of the safety technologies for V2V are already available in cars,
although they tend to be offered primarily on higher-end models.
Together,
the currently available technologies and the future V2V systems may
effectively form a kind of autopilot for the road. Said Strassburger:
“The long-term trajectory for these technologies is the vehicle that
drives itself—the driverless car.”
