TOKYO, Japan --- Denso Corp. said it will test an anti-collision, vehicle-to-vehicle communications system on public roads in Abashiri, a city on the eastern coast of Hokkaido in Japan, from April to March 2011.

The accident-prevention system allows in-vehicle communications devices to send out warning signals if automobiles come close, said the auto parts maker affiliated with Toyota Motor Corp.

The system is designed to help drivers prevent crashes at blind intersections or in low-visibility conditions caused by wind-blown dust or other factors. The company also intends to allow the system to warn drivers of approaching emergency vehicles.

Abashiri was chosen as the test site because its geographical and climate characteristics make various tests possible, the company said. The Ministry of Internal Affairs and Communications has approved the public road tests as a special deregulation zone project for ubiquitous Internet networking.
