Intelligent transport systems (ITS) improve convenience in motorized societies and reduce the environmental effects of automobiles by connecting them closely to the transportation infrastructure they use. Mitsubishi Heavy Industries, Ltd. (MHI) has been developing and delivering two unique ITS applications for many years: the Electronic Road Pricing (ERP) system and the Electronic Toll Collection (ETC) system. Together they eliminate traffic jams at tollbooths, control traffic volumes, improve fuel efficiency, and offer many other benefits. ITS will help create a more environmentally friendly and sustainable society by balancing and controlling traffic flow with enhanced On-Board Equipment and the shared use of Infrastructure by individual drivers and public transportation networks.
