The Japanese manufacturer OKI developed a mobile phone that can save your life from being hit by a moving vehicle: by warning driver and pedestrian of the impending collision.

The devise supports a Dedicated Short Range Communication (DSRC) transceiver. DSRC is radio communications standard developed for the automotive industry whose primary use today is electronic toll collections.

The location information of both the phone and the vehicle would derived from global positioning satellites (GPS). According to Oki, "Pedestrians with this device can create a DSRC wireless area (within a several hundred meters radius) with vehicles equipped with inter-vehicle communication equipment. The device sends out its location information at a regular time interval within the area. When the two locations become close and when the received power from each device goes over the specified value, location information will constantly be exchanged. In addition, when there is a high possibility of a traffic accident based on the location information, it will warn the users beforehand...Pedestrians will be warned through the vibration function on their mobile phones, and drivers will be informed through voice guidance function on the inter-vehicle communication equipment, helping avoid danger for both drivers and pedestrians."

OKI aims is to achieve smaller sized DSRC wireless modules, and improve the user interface. OKI will also make efforts to integrate 3G mobile phones, PHS, and wireless LAN functions into a single mobile handset as part of a large-scale public-private experiment to be conducted in Japan. OKI also plans to achieve compatibility with IEEE802.11p, the DSRC international standard.

The project is part of Oki's involvement in the "New IT Reform Strategy" announced by Japan’s Cabinet Office to develop technologies that can reduce the number of pedestrians killed in traffic accidents. The government and private sectors will start large-scale trials for systems to improve pedestrian safety from the fiscal year ending March 2009, with plans to start operations from the fiscal year ending March 2011.

“We focused our attention on leveraging mobile phones, since they are used by over 80 percent of the population in Japan," said Masao Miyashita, president of Systems Solutions Company at Oki Electric Industry. "Our goal is to improve the safety of vulnerable road users including pedestrians and those on bicycles. We plan to develop products in line with the New IT Reform Strategy and to work closely with car manufacturers to develop applications to improve safe driving and improve safety for pedestrians."
