Abstract:The Intelligent Vehicle Highway Systems (IVHS) program applies advanced and emerging technologies in such fields as information processing, communications, control, and electronics to surface transportation needs. If these technologies can be effectively stimulated, integrated, and deployed, the public will be able to more efficiently use the Nation’s highway infrastructure and energy resources by making more informed choices about travel and route alternatives. Successful deployment of IVHS services and systems will achieve improvements in safety, mobility, and productivity, and reduce harmful environmental impacts, particularly those caused by traffic congestion.
As described in the National IVHS Program Plan, the IVHS program is focused on the development and deployment of a collection of user services. Twenty eight inter-related user services have been defined to date as part of the national program planning process. User services are defined, not along lines of common technologies, but based upon the services or benefits that various users might receive. The services are in various stages of maturity; some are available today, others will require significant research, development, testing, and advances in technology applications before they are ready for deployment.
Deployment of these user services will help to attain the goals defined for the national IVHS program by creating safer and better informed travelers, improved traffic control systems, and more efficient transit and commercial vehicle operations. Because of their interdependencies, it is likely that individual user services will not be deployed independently. For example, a fully functioning Route Guidance service will require real-time traffic information that is collected and processed by the Traffic Control service. Thus, user services have been grouped into “bundles,” based on likely deployment scenarios. The bundles of user services are shown in the table on the following page.
