A major national initiative is underway to apply proven information, communications and control technologies to surface transportation to improve its efficiency and reduce its negative impacts. Collectively, these applications are known as Intelligent Vehicle Highway System or IVHS and are expected to create a $200 billion industry over the next 20 years. IVHS will be applied to all types of vehicles (trucks, buses and cars), to information devices (signs, computers, kiosks, and hand-held devices), and to all parts of the surface transportation system (freeways, urban arterials, rural roads, transit stations, ports, and intermodal connections). Deploying IVHS can improve safety, reduce congestion, improve mobility and accessability, reduce environmental impact and increase energy efficiency, improve economic productivity and create a domestic IVHS industry. This document provides the latest information on the IVHS Archi-tecture Development Program, highlighting the four architectures being developed. This document also contains a mechanism by which stakeholders can give feedback. |
