The National Highway Traffic Safety Administration is working with auto makers to require vehicles to communicate with one another. The aim is to cut collisions, death and injuries. They hope to prevent crashes in the first place as compared to insuring that accidents are survivable.
A radio signal would continually transmit a vehicle’s position, heading, speed and other information. Cars and light trucks would receive the same info back from other cars. The vehicle’s computer would alert its driver to an impending collision. Alerts could be a flashing message, an audible warning or a driver’s seat that rumbles. Some systems could brake to avoid an accident. Vehicle to vehicle communications could prevent up to 80 percent of accidents that don’t involve drunken drivers or mechanical failure.
Your car would “see” when another car or truck equipped with the same technology was about to run a red light. Your car would know and alert you when a car several vehicles ahead had made a sudden stop. The technology works up to about 300 yards.
And the cost? Government officials decline to give an estimate, but the transportation society’s estimation is $100 to $200 per vehicle.
If a community wishes to use them, technologies are available for roadways and traffic lights to talk to cars, sending warnings of traffic congestion or road hazards in time for drivers to take a detour.
Conversation between vehicles is seen as the basis for future self-driving cars.
