Development of Vehicle-Infrastructure Cooperative Systems Using Infrared Beacon and DSRC: Hiroshima DSSS Field Operational Test

This paper explains vehicle-infrastructure cooperative systems that alert the driver to a possible collision due to poor sight visibility or a careless oversight. The authors describe a cooperative system that uses infrared (IR) beacons and dedicated short range communication (DSRC) to judge risky situations correctly and to inform the driver at the correct time. They also describe field tests in which roadside infrastructures for verification tests were set up at three high-accident locations in Hiroshima City. The preliminary experiments were conducted from January to March in 2008. The tests were undertaken to verify the cooperation between the IR beacon and the DSRC, to measure the change of driving behaviors before and after the systems were implemented, and to assess the system acceptability. Results showed that the cooperative system between the IR beacon and the DSRC was successful in preliminary tests. The change of driving behaviors before and after the systems were implemented could be measured quantitatively. Additional tests with general drivers will be conducted next.
