Intelligent Vehicle and Highway Systems (IVHS) and Advanced Transport
Telematics are the names which have been used in America and Europe, respectively, to
describe the application of information, communications, data acquisition, and control system
technologies in surface transportation. These range from mundane traffic advisory message
signs on freeways and transit passenger information systems to visionary automated highways
where computer-controlled cars might tailgate a few feet apart at 100 mph or more.

IVHS technologies could reshape our communities and societies in far-reaching ways
over the next several decades, affecting our lifestyles, environment, economic structure, and
social equity nearly as much as the automobile has over past decades. The fundamental
architecture and vision of IVHS established in the mid-1990s may serve as a foundation for a
technology-driven transformation with considerable consequences. We must ensure that these
technologies are harnessed to serve our long-term social, economic, and environmental goals.
This will require much broader public participation in IVHS policy making, the establishment
of clearer performance objectives and measures for transportation management systems to
guide IVHS deployment, and broad-based assessment of the social and environmental impacts
of IVHS
