Development of ITS technologies (2)

摘要

ITS (Intelligent Transport Systems), that solves various problems on road traffic by networking person, vehicle and road, is in steady progress. VICS (Vehicle Information and Communication System) and ETC (Electronic Toll Collection System) are being spread for common use and proving tests on actual roads are being conducted for AHS (Advanced Cruise-Assist Highway Systems) projects. For this ITS business field, we have been developing technologies classified into three networks systems; wired, wireless, and in-vehicle networks. We report on the main results and related trends on IP (Internet Protocol) network systems, anti-icing system for roads, electromagnetic wave absorbers, leaky wave guide, ITS data bus, and Inter-vehicle communication systems which were developed by these technologies.
