Now in development, vehicle-to-vehicle (V2V) communication systems use a GPS receiver, a radio/antenna and a computer to share automobile location and movement information with other V2V-equipped vehicles up to a quarter mile away. That information is then analyzed and used to alert the driver to potentially hazardous situations. Warnings can be provided in a variety of ways, including sounds, visual icons, control feedback and seat vibrations.
More advanced systems may also employ vehicle-to-infrastructure (V2I) communications that allow the car to receive driving condition information from traffic lights, road signs or even the highway itself. Common notifications might include traffic congestion, speed limits, or height restrictions on bridges and tunnels. The combination of V2V and V2XI technology is often referred to as V2X.
When V2X capabilities are integrated with advanced driver assistance systems, the vehicle could take control of the brakes and/or steering to avoid a collision if a driver fails to react in time. Unexpected emergency situations combined with ineffective driver reactions result in millions of crashes every year. The National Highway Traffic Safety Administration projects that V2X systems could help prevent up to 81 percent of collisions involving drivers not impaired by drugs or alcohol. As V2X-equipped vehicles begin to appear on our roadways, shared information could also be used to smooth traffic flow, reduce congestion, improve fuel economy and cut emissions.
Automakers, technology providers, research institutes and governmental agencies are all engaged in developing V2V and V2I technology. The Department of Transportation is expected to decide some time in 2013 whether V2X systems should be among the safety features built into our vehicles. Given its potential benefits, there is a good possibility your next new car will employ V2X communications to help you be a better driver.
