TRB Transportation Research Circular E-C048: Freight Transportation Research Needs Statements identifies critical issues in freight transportation as a resource for researchers in the freight area and serves as a seedbed for further discussion and analysis from a wider cross-section of freight practitioners.
Major trends affecting the future of the United States and the world will dramatically reshape transportation priorities and needs. The American Association of State Highway and Transportation Officials established the NCHRP Project 20-83 research series to examine global and domestic long-range strategic issues and their implications for departments of transportation (DOTs) to help prepare the DOTs for the challenges and benefits created by these trends. NCHRP Report 750: Strategic Issues Facing Transportation, Volume 1: Scenario Planning for Freight Transportation Infrastructure Investment is the first report in this series. NCHRP Report 750, Volume 1 provides decision makers with a critical analysis of the driving forces behind high-impact economic and social changes as well as sourcing patterns that may affect the U.S. freight transportation system. A detailed discussion of the driving forces is contained in NCHRP Web-Only Document 195: Driving Forces Influencing Future Freight Flows. NCHRP Report 750, Volume 1 also introduces scenario planning as a tool that can be used in conjunction with other planning methods to improve the quality of long range transportation infrastructure planning.
