How car-to-car communication could keep you safe

In the near future your car could be communicating with other cars on the road in an effort to keep you safe.

The National Highway Traffic Safety Administration said this week it will begin drafting rules requiring that new cars and light trucks be equipped with car-to-car communication technology. That technology enables vehicles to warn each other of potential danger in time to avoid collisions. It uses a radio signal to continually transmit a vehicle's position, heading, speed and other information.

Researchers believe vehicle-to-vehicle communication will dramatically reduce the amount of left-turn and intersection crashes. A research report by the NHTSA estimates that the technology could prevent as many as 592,000 left-turn and intersection crashes a year, saving 1,083 lives.

The technology works up to about 300 yards away. A car would know if another was about to run the intersection, even if the view for the driver was obstructed. The driver would also be alerted if a car several vehicles ahead in a line of traffic makes a sudden stop.

Roadways and traffic lights could also soon start talking to cars and warning them of traffic congestion and road hazards in time to take a detour, and their car will know where the best detour is located.
