Cars equipped with vehicle-to-vehicle (V2V) communications technology to avoid accidents

The future of automotive safety will involve cars equipped with vehicle-to-vehicle (V2V) communications technology, which enables them to talk to each other and warn drivers of impending collisions.

The Department of Transportation of the US Government plans to launch a yearlong, real-world test of V2V technology involving about 3,000 cars, trucks, and buses with volunteer drivers.

The vehicles will be equipped to continuously communicate over wireless networks, exchanging information on their location, direction, and speed 10 times per second with other vehicles within about 1,000 feet. An on-board computer analyzes the information and issues danger warnings to drivers. More advanced versions of V2V systems will be able to take control of the vehicle to prevent an accident if the driver is slow to react. In addition, connected cars will alert drivers if they do not have enough time to make a left turn because of oncoming traffic. Connected cars also will be able to exchange information with similarly equipped transportation infrastructure, such as traffic lights, signs, and roadways. The stream of vehicle-to-infrastructure information could give traffic managers a better idea of traffic flows, resulting in better timing of traffic signals. U.S. National Highway Traffic Safety Administration researchers have been working on the technology with eight automakers.
