... This publication reflects the collective judgment of the members of the Executive Committee regarding issues of priority concern at the time of publication. Critical issues are defined as those that have a significant impact on achieving societal goals across all modes.

We encourage readers to explore the wealth of Transportation Research Board and National Academies' publications on these issues and the many dimensions of the critical issues described therein.2 Also unlike previous editions, this edition relies heavily on metrics whenever possible to support inclusion of a topic and to show progress, or not, in addressing the societal goals identified.
