Major Cities' Adaptation to Global Climate Change
Air Quality, Environmental Process
Research Idea Scope
Major cities contain critical multi-modal infrastructure for both the movement of people and goods including some of the oldest systems still operated in the U.S. Climate change impacts such as rising sea level, increased storm intensity and increased heat could cause unprecedented disruption to major facilities and economic systems. This research would respond to questions such as assessing risk by region and system characteristics, considering potential adaptation strategies and their impact on economic and social well being. (TRB critical issue: Energy and Environment)
The purpose of this research is to provide relevant approaches for relocating, redesigning, or hardening transportation systems and structures given anticipated long-term climate changes for the unique needs of transportation in major cities.
RESEARCH PROPOSEDGeneralized work on adaption issues has been conducted for highways, transit, ports, and other modal facilities. This research project would take the generalized information and apply them to the unique circumstances of major cities. The work would be multimodal and consider the difficulty of working in a highly constrained physical environment comprised of multiple legacy systems. The research would consider the interaction and impact of non-transportation infrastructure and private development on transportation adaption options. The research would cover issues of reconstruction along with questions about changes in operational and maintenance regimes based on adaptation needs.

Urgency and Payoff
URGENCY AND PAYOFF POTENTIALThere is significant potential payoff. Major cities will need to reconstruct major portions of obsolete urban infrastructure originally developed 50, 100, or more years ago. New and reconstructed structures should provide similar if not longer durability. If the structures do not anticipate long-term changes sea level, storm surges, or rainfall intensity, they again will need to be rebuilt.
