Very large urban areas - over 3 million population.
Large urban areas - over 1 million and less than 3 million population.
Medium urban areas - over 500,000 and less than 1 million population.
Small urban areas - less than 500,000 population.
a Rank is based on the calculated point change with the highest number corresponding to a rank of 1.
b Averages weighted by Vehicle Miles Traveled
NOTE
The Travel Time Index (TTI) is the ratio of peak period travel time to free flow travel time. The TTI expresses the average amount of extra time it takes to travel in the peak relative to free-flow travel. A TTI of 1.3, for example, indicates a 20-minute free-flow trip will take 26 minutes during the peak travel time periods, a 6-minute (30 percent) travel time penalty.
Methodology and data sources have been changed in 2007 and were applied retroactively to past years, these figures are not comparable to those in past editions of NTS.
