"TRB's National Cooperative Highway Research Program (NCHRP) Report 750: Strategic Issues Facing Transportation, Volume 1: Scenario Planning for Freight Transportation Infrastructure Investment analyzes the driving forces behind high-impact economic and social changes as well as sourcing patterns that may affect the U.S. freight transportation system. The report 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. Four future scenarios were developed as part of the project that created NCHRP Report 750, as well as a detailed methodology that planners can follow to conduct their own scenario planning workshops. The scenarios and methodology are included in a DVD format with the print version of the report. A detailed discussion of the driving forces analyzed in NCHRP Report 750, Volume 1 is contained in NCHRP Web-Only Document 195: Driving Forces Influencing Future Freight Flows. NCHRP Report 750, Volume 1 is the first in a series of reports being produced by NCHRP Project 20-83: Long-Range Strategic Issues Facing the Transportation Industry. 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 (AASHTO) established the NCHRP Project 20-83 research series to examine global and domestic long-range strategic issues and their implications for state departments of transportation (DOTs); AASHTO's aim for the research series is to help prepare the DOTs for the challenges and benefits created by these trends"--Publisher description.
