Recent Japanese projects of AVCS-related systems

This paper introduces recent developments of Japanese AVCS-related systems following the general introduction of the Japanese Intelligent Vehicle Highway System/ATT. The Vehicle Information Communication System and Universal Traffic Management System, categorized as ATMS/ATIS, are now at the stage of practical implementation. The Advanced Road Transportation System, featured by infrastructure-oriented AVCS with use of leakage coaxial cables, and an advanced safety vehicle aiming at active safety, and their experiments have been conducted. Some experiments on intervehicle communication, which is one of the technologies in Super Smart Vehicle System for the future AVCS, are also described.
