a Averages weighted by vehicle-miles traveled.
NOTES: The Travel Time Index is calculated as the ratio of travel time in the peak period to the travel time at free-flow conditions. A value of 1.35 indicates a 20 minute free-flow trip takes 27 minutes in the peak. Free-flow speeds (60 mph on freeways and 35 mph on principal arterials) are used as comparison threshold.
Very large urban areas have a population of over 3 million. Large urban areas have a population of over 1 million and less than 3 million. Medium urban areas have a population of over 500,000 and less than 1 million. Small urban areas have a population of less than 500,000.
The 2010 Urban Mobility Report methodology and data sources have been significantly revised and the total number of cities reported rose from 90 to 101; these figures are not comparable to those in past editions of this publication. This is due to methodological changes such as covering a 24 hour period instead of only peak periods.
