Introduction of pilot projects of Driving Safety Support Systems (DSSS)

摘要

The National Police Agency (NPA) of Japan has been developing a Vehicle-InfrastructureCooperation System for road safety, which we call "Driving Safety Support Systems" or"DSSS". The purpose of the DSSS is to prevent traffic accidents by providing drivers withvisual and audible information concerning potential dangers such as pedestrians crossingintersections, other vehicles approaching the intersections, and so on. DSSS has two types, aninformation provision type and a decision type. The investigation and development of theinformation type of DSSS started from 1997 by NPA and the Universal Traffic ManagementSociety of Japan or "UTMS Japan", which is an organization to promote ITS in Japan. Basedon these investigations and developments, the NPA decided to start pilot projects o finformation provision type of DSSS from 2006 fiscal year by a government budget. One pilotproject ( including four subsystems) has been operated in Tokyo from March 2007, and theother (including five subsystems) has been operated in Saitama from March 2008. In thispaper, I will explain the pilot systems and the effects.
