[ NCHRP 20-83 (Long-Range Strategic Issues Facing the Transportation Industry) ]

  Project Data
Funds: $1,000,030
Research Agency: PB Americas, Inc.
Principal Investigator: Michael Meyer
Effective Date: 12/27/2009

Comments: The final project deliverables are available as NCHRP Report 750, Volume 2.

The objectives of this research were to (1) synthesize the current state of worldwide knowledge regarding the probable range of impacts of climate change on highway systems by region of the United States for the period 2030-2050; (2) recommend institutional arrangements, tools, approaches, and strategies that state departments of transportation (DOTs) can use during system planning, design, construction, operations, and maintenance to adapt infrastructure and operations to these impacts and lessen their effects; and (3) identify future research and activities needed to close gaps in current knowledge and implement effective adaptive management.

The key products of this research, a practitioner's guide to climate change adaptation and a project final report summarizing the supporting research, are available as NCHRP Report 750, Volume 2, Climate Change, Extreme Weather Events, and the Highway System: Practitioner's Guide and Research Report.

In addition to the practitioner’s guide and research report, this project also developed the following items:
• A software tool that runs in common web browsers and provides specific, region-based information on incorporating climate change adaptation into the planning and design of bridges, culverts, stormwater infrastructure, slopes, walls, and pavements.
• Tables that provide the same information as the previously mentioned software tool, but in a spreadsheet format that can be printed.
• Two spreadsheets that illustrate examples of the benefit–cost analysis of adaptation strategies discussed in Appendix B of Part I of NCHRP Report 750, Volume 2.

These three items are available on a CD-ROM that is included with a print version of the report. The CD-ROM is also available for download from TRB’s website as an ISO image. Links to the ISO image and instructions for burning a CD-ROM from an ISO image are provided below.
