Samenvatting
The Advanced Cruise-Assist Highway System Research Association (AHSRA) was founded in 1996, and started Japanese AHS (Advanced Cruise-Assist Highway System) research projects. In the project, principal user services for safety have been defined. This paper gives a brief discussion of experimental results in both a computer simulation and an experiment in test track for a function of information technology based road-side facility in the AHS. As a result of the experiment for six of principal user service for safety, the function was determined to give a safety road condition to drivers. For the covering abstract see ITRD E114174.
