As has been the practice in past versions of the Commuting in America series, this brief further considers the meanings of the data presented in the previous briefs. Unlike the prior briefs, this one is more subjective in nature, with the authors interpreting the data on commuting in terms of relative significance and implications for transportation planning and policy. Depending upon their knowledge of transportation and their geographic context and perspective, readers may have differing priorities and interpretations from those developed by the authors based on a national overview. While acknowledging the differences in perspectives, the mandate has been that each brief be objective and state only what the facts support, without bias toward or advocacy of any particular viewpoint, to assure objectivity. This brief presents to readers the authors’ interpretations of possible directions that overall commuting behaviors may take. The views expressed here are those of the authors and do not necessarily reflect the views of AASHTO, its members, or its staff.
