The application of intelligent vehicle highway systems technology to high-occupancy vehicle facilities : a white paper prepared for the Transportation Research Board HOV Systems Committee.

This white paper examines the application of intelligent vehicle-highway systems (IVHS) technology to high-occupancy vehicle (HOV) facilities. Intelligent vehicle-highway systems represent a continually evolving group of advanced technologies directed at improving the efficiency of the overall transportation system. HOV facilities, which provide priority measures for high-occupancy vehicles, are intended to help maximise the person-carrying capacity of the roadway. As outlined in this paper, combining many IVHS technologies with HOV facilities offers numerous benefits related to improving the efficiency of the total transportation system, increasing mobility, reducing congestion, improving air quality, and reducing fuel consumption. These benefits can be realised through the development of an HOV IVHS program. This paper outlines the initial focus and elements of such a program and is intended to provide a starting point for the development of a comprehensive and co-ordinated HOV IVHS research, demonstration, and full implementation program. The proposed HOV IVHS program builds on the activities currently underway in a few areas, represents a multi-year, multi-phased effort, and has a projected total budget of approximately $1.2 to $3.0 Billion over the next twenty years. This conference was conducted by the Transportation Research Board, National Research Council, Municipality of Metropolitan Seattle and Washington State Department of Transportation in co-operation with the Federal Highway Administration and the Urban Mass Transportation Administration. This paper appears in appendix 1 of the conference proceedings; the presentation of this paper appears on pages 35-39.
