U.S Government wants to male cars talk to each other

A research report released by the National Highway Traffic Safety Administration of the u.s estimates that the technology could eventually prevent 592,000 left-turn and intersection crashes a year, saving 1,083 lives. The agency said it will begin drafting rules to require the technology in new vehicles.The technology uses a radio signal to continually transmit a vehicle's position, heading, speed and other information. Similarly equipped cars and trucks would receive the same information, and their computers would alert drivers to an impending collision.A car would "see" when another car or truck equipped with the same technology was about to run a red light, even if that vehicle were hidden around a corner. A car would also know when a car several vehicles ahead in a line of traffic had made a sudden stop and alert the driver even before the brake lights of the vehicle directly in front illuminate. The technology works up to about 300 yards away.If communities choose to invest in the technology, roadways and traffic lights could start talking to cars, as well, sending warnings of traffic congestion or road hazards ahead in time for drivers to take a detour.The technology is separate from automated safety features using sensors and radar that are already being built into some high-end vehicles today and which are seen as the basis for future self-driving cars. But the american
government and industry officials see the two technologies as compatible. If continuous conversations between cars make driving safer, then self-driving cars would become safer as well.
The information sent between vehicles does not identify those vehicles, but merely contains basic safety data, NHTSA said. "The system as contemplated contains several layers of security and privacy protection to ensure that vehicles can rely on messages sent from other vehicles," the agency said.Adding the technology to new vehicles or retrofitting existing ones is expected to cost about $100 to $200 per vehicle.
Communications Commission to preserve the 5.9 GHz radio frequency for vehicle-to-vehicle communications.The frequency was initially expected to be dedicated to transportation technologies, but the commission has said it is exploring whether that frequency can be used for other wireless demands as well.
