NCHRP Project 20-68A U. S. Domestic Scan Program is intended to facilitate technology transfer and innovation among state departments of transportation (DOTs) and others through personal contact.  A “scan” approach typically entails field visits to observe promising new practices, identify pertinent development and application issues, and assess appropriate technology transfer opportunities and methods. The scan visit focuses on face-to-face discussion of current experience, providing opportunities for a uniquely rich exchange of information that is difficult or impossible to replicate through written materials, telephone conversations, and e-mail correspondence.  The scan visits themselves are a productive means for spreading information and innovation, but scan projects typically include efforts to encourage scan-team members to expand the circle of information exchange through preparation and dissemination of a report of each scan, publications in trade and professional journals, and participation in conferences and other peer-to-peer forums.  Efforts must be made to assess the effectiveness of scans and post-scan dissemination activities as means for disseminating new concepts and practices and encouraging innovation.
