Notes: The Methodology to calculate congestion performance measures was updated to reflect more comprehensive data collection including congestion estimates for each of the 471 U.S. urban areas. The congestion estimates for all study years are recalculated every time the methodology is altered to provide a consistent data trend. For a detailed explanation of the updated methodology, see the 2015 Urban Mobility Scorecard Methodology, available at http://mobility.tamu.edu/ums/report/.
