Corporate Master Plan for Research and Deployment of Technology & Innovation
Publication No. FHWA-RD-03-077
Released in April 2003, the Corporate Master Plan (CMP) addresses recommendations from FHWA's 7 guiding principles, including 26 agency commitments. The commitments include setting research agendas, increasing the role of external stakeholders, using multiyear plans (or "roadmaps"), and evaluating research results and deployment.
To implement the plan, the FHWA R&T Leadership Team has identified areas for multiyear plans, promoted self assessments by functional areas for current R&T activities, and developed a list of priority, market-ready technologies and innovationsincluding the nine technologies embraced by the Technology Implementation Group (TIG) at the American Association of State Highway and Transportation Officials. These priority technologies and innovations were the focus of an FHWA exhibit at the annual meeting of the Transportation Research Board in January 2004.
Copies of fact sheets (listed below) on the technologies and innovations, and information about the implementation of the plan, are available on the new "FHWA Research and Technology" Web site, www.fhwa.dot.gov/crt/index.cfm. Printed copies of the CMP are available from the R&T Product Distribution Center.
