Megaregions: Literature Review of the Implications for U.S. Infrastructure Investment and Transportation Planning
Executive Summary
In the twenty-first century, the United States faces increasing challenges in terms of economic competitiveness, quality of life, traffic congestion, aging transportation infrastructure, and scarcity of natural resources. These challenges are particularly difficult because they are not confined to traditional geographic or political borders, but arise from the interactions between cities and regions. In order to address these challenges, local, state, regional, and federal actors may be well served by planning for critical infrastructure on a scale larger than has been common in transportation and regional planning history and practice. One potential approach to address these challenges, and take advantages of the opportunities that arise from growing urban agglomerations, is the idea of the "megaregion."
