Recent advances in communications and electronics technologies promise to allow significant improvements in the overall efficiency. These advances promise to enable real-time adjustments of traffic to current and predicted travel conditions, more effective trip planning and real-time route selection and improvement in overall road safety. In developing and planning for these systems we need to make assessments about how each of these promises are actually going to pay off. [ILLEGIBLE] there markets for these systems? What are the likely barriers to adoption? What policies can be adopted to overcome these barriers? What are the likely impacts of these developments? How will social and institutional considerations impinge on these developments? This paper presents opinions on these questions regarding the future development of intelligent vehicle-highway systems (IVHS) in North America.
