The National Highway Traffic Safety Administration (NHTSA) issued a proposed rule to require installation of vehicle-to-vehicle (V2V) communications technology on new cars. A wireless chip would allow connected cars to communicate over a special wireless frequency called Dedicated Short-Range Communications (DSRC). The DSRC system operates in a fashion similar to the Wi-Fi used in personal computers. Vehicles would transmit a 360-degree status report location, speed and direction to other connected vehicles within the immediate vicinity. Computers in the cars would be able to respond to an impending crash by sending an alert to the driver (flashing message, audible warning, rumbling seat or steering wheel). The technology could eventually be more interactive, applying the brakes, increasing speed or turning the car.
V2V devices would speak the same language through standardized messaging developed with industry. This would also allow aftermarket companies to market products to retrofit older cars. Once the rule is finalized, the automakers will be provided a four-year phase-in period to install the products on new vehicles.
In a separate action, the Federal Highway Administration is expected to soon issue guidance for Vehicle-to-Infrastructure (V2I), allowing communications with roadways and traffic lights in order to improve mobility and safety, and reduce congestion.
