In this report, which is updated periodically by the TRB Executive Committee, a series of challenging questions are posed to explore issues and opportunities that may arise 10 to 20 years into the future. These questions, 63 in all, have been organized into 12 topic areas and provide a way to frame future areas of research, policy analysis, and debate.Critical issues identified in this report deserve attention because of transportation’s central role in serving individuals and society. This document serves to sharpen society's collective understanding of transportation and its ramifications, while informing decisions by individual citizens and officials in both the public and private sectors. The issues have been identified and documented from a U.S. perspective, and are also common across developed nations.Download the executive overview, Critical Issues in Transportation: Policy Snapshot and or visit www.TRB.org/criticalissues from your mobile device.
