Gulf Coast Study, Phase II, Interagency Agreement Between Research & Innovative Technology Administration and Federal Highway Administration

The Gulf Coast Study, Phase 1, completed in 2008, studied how changes in climate over the next 50 to 100 years could affect transportation systems in the U.S. central Gulf Coast region and discussed how to account for potential impacts in transportation planning. Phase 2 will build on the information developed in Phase 1 to develop more definitive information about impacts at the local level in a particular Metropolitan Planning Organization (MPO) or smaller region and will focus analysis on the key transportation links, for day to day systems operations and emergency management. The study will develop more precise tools and guides for State departments of transportation (DOTs) and MPO planners to use in deciding how to adapt to potential climate impacts and determine vulnerability for key links for each mode. Phase 2 will also develop a risk assessment tool to allow decision makers to understand vulnerability to climate change and develop a process to implement transportation facility improvements in a systematic manner.
