While much of the current research on Intelligent Vehicle Highway Systems (IVHS) focuses on its technological aspects and economic benefits, little consideration is being given to the potential non-economic benefits of IVHS to individuals and society and the related issue of acceptability of the system among various user groups. Three stages of research dealing with the non-economic benefits of IVHS and user acceptance are discussed. Next, the results of a recently completed survey exploring these topics are reviewed. Survey findings cover the potential usefulness of various traffic advisories and the willingness of drivers to pay for them. Sentiments of drivers experiencing varying degrees of traffic congestion and stress in their commuting are considered as are feelings about IVHS as a solution to traffic congestion. Finally, implications of findings and directions for future research on user acceptance and non-economic benefits are discussed.

Following a review of the potential non-economic consequences of deploying an Intelligent Vehicle-Highway System, the paper discusses the need for a systematic program of research dealing with the behavioral aspects of the new technology. A research agenda covering one component of behavioral research is then outlined and recommendations are made for specific studies as part of that agenda.
