Toyota develops onboard DSRC unit to enhance traffic safety

Sep 05, 2009 (Datamonitor via COMTEX) -- Toyota Motor has developed an onboard dedicated short-range communications unit intended to increase traffic safety by providing drivers real-time, close-vicinity traffic information.

The dedicated short-range communications unit (DSRC) was developed in co-ordination with an effort in Japan to develop next-generation roads. Toyota plans to offer the DSRC unit in Japan on a new vehicle model soon to be launched.

According to the company, the navigation-system-linked DSRC unit, through the use of intelligent transportation systems (ITS) technologies, including Japan's electronic toll collection framework, receives a wide range of traffic information via vehicle-infrastructure communications and provides it to highway drivers in visual form and through voice guidance.


The unit also alerts drivers to obstacles they cannot see on the road ahead around curves, such as stopped vehicles and stopped-up traffic. It also alerts drivers to merging vehicles.

Toyota's plan to offer the DSRC unit on a production vehicle represents the practical application of an ITS vehicle-infrastructure co-operative system that was developed through joint private-public sector research (from February 2005), verified in tests on the Tokyo Metropolitan Expressway (from May 2007) and demonstrated as part of the ITS-Safety 2010 project conducted in fiscal year 2008.
