This report examines the market dynamics and benefits associated with the deployment and diffusion of Intelligent Transportation Systems (ITS) technologies across the United States. For several ITS technologies, the current market structure, events that have influenced the historical deployment trends, and factors that may play a role in future deployment are all examined and analyzed. This qualitative research consists primarily of interviews with suppliers and public sector purchasers. The report also presents monetized estimates of the mobility, safety, and environmental benefits produced by a selection of ITS technologies at their current nationwide level of deployment. These estimates are derived from the results of previous studies gathered through an extensive literature review.
