American officials are close to approving new rules for enabling vehicles to communicate with each other. Officials hope the new technology will reduce the number of traffic accidents. Automobile manufacturers may be required to equip all new cars with what are being called ‘vehicle-to-vehicle’ communication devices within the next three years. Vehicle-to-vehicle, or V2V, is a communication technology. It enables vehicles to share information about their speed and movement at a rate of 10 times a second. Cars will be able to identify possible dangers within about 300 meters. The cars will then warn their drivers or even take action to avoid an accident. The drivers will be able to see, hear or even feel warning signals. The U.S. National Highway Traffic Safety Administration expects the new system to reduce the number of car accidents by as much as 80 percent. Critics admit that V2V technology is a major development. But they are concerned about possible conflicts with other wireless devices. They say those devices already operate in the wireless frequencies planned for V2V technology. Scott Belcher is the chief operating officer of a group called Intelligent Transportation Society of America. He says people may also be concerned about their privacy. Government agencies and private industry have already invested almost $1 billion in research. U.S. officials expect the new technology will be required in American vehicles by early 2017. They believe it is the first step toward a better and safer transportation system.
