The Department of Transportation’s New Communication System Helps Cars Avoid Crashes

WASHINGTON (AP) — As a safety demonstration, it was a heart-stopper: A Ford Taurus was seconds away from cruising through an intersection when suddenly a row of red lights pulsed on the lower windshield and a warning blared that another car was approaching fast on the cross street.
Braking quickly, the driver stopped just as the second car, previously unseen behind a large parked truck, barreled through a red light and across the Ford’s path.
The display at a recent transportation conference was a peek into the future of automotive safety: cars that to talk to each other and warn drivers of impending collisions. Later this summer, the government is launching a yearlong, real-world test involving nearly 3,000 cars, trucks and buses using volunteer drivers in Ann Arbor, Mich.
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. A computer analyzes the information and issues danger warnings to drivers, often before they can see the other vehicle.
