Although the performance advantages of cooperative ITS systems are generally appreciated, the deployment challenges that they pose represent a significant impediment. This report begins with a summary of the types of deployment challenges faced by cooperative information systems and cooperative vehicle-highway automation systems (CVHAS), both of which require coordination of deployment of vehicle and infrastructure-based elements. The institutional challenges are discussed first, followed by the technological challenges. In each case, current progress in overcoming these challenges is reviewed and the additional needed steps are suggested. Considerable attention is devoted to showing the range of enabling technologies that are already available on passenger cars in the U.S.
