^a A peak traveler is estimated to travel from 6:00 a.m. to 9:00 a.m. and 4:00 p.m. to 7:00 p.m.

Key:

Very large = over 3 million population (e.g., New York-Northern New Jersey).
Large = 1 million-3 million population (e.g., San Diego).
Medium = selected areas with 500,000-1 million population (e.g., Charlotte).
Small = selected areas under 500,000 population (e.g., Colorado Springs).

Note: See Glossary for definitions of delay and congestion cost. Methodology and data sources have been changed in 2009 and applied retroactively to past years, these figures are not comparable to those in past editions of Pocket Guide.
