Smart Car-to-Car Navigation Network in Japan

nomrniceguy writes "Japan now boasts some of the latest technology in zapping computerized data to millions of cars, delivering what may be the world's smartest way to drive. New navigation systems in Japan can quickly tell drivers which roads have traffic jams. A computerized FM radio broadcast system that collects and sends information from more than 28,000 infrared and radio-wave beacons installed along roads, they can also calculate how many seconds it would take to drive through virtually every block of the nation's cities and then find the fastest routes. In tests by the National Institute of Information and Communications Technology, a Japanese research group, cars connect to other cars wirelessly to get information about a traffic accident or an approaching ambulance."
