It doesn’t take much to reduce traffic. In fact, if only 5 cars in a thousand had new “car talking” technology, it could eliminate a traffic jam, German researchers said.
Germany is implementing such a vehicle-to-vehicle (V2V) communications system. It will send data from in-car sensors over an 802.11p WLAN. Data from the sensors would be analyzed by traffic authorities and sent to motorists through their navigation system, text messages and radio traffic reports, said Autopia. A one-year trial of the technology just ended and is being analyzed before it is presented to the public.
U.S. automakers including Ford are also experimenting with V2V communication. Ford is demonstrating a car to car communication system based on WiFi and GPS that can alert the car behind you that you’ve slammed on the brakes. The technology is expected to see regulation by the National Highway Traffic Safety Administration (NHTSA) in 2013.
