Bus Profile

KEY:  N = data do not exist; R = revised; U = data are unavailable.

^a In 2003, the Federal Motor Carrier Safety Administration implemented a program to improve reporting by Class I intercity bus carriers. This accounts for the large increase in Number of operating companies between 2002 and 2003, and as a result the large increase in Operating revenues and Operating expenses. For all years, New Jersey Transit has been excluded from the totals because of its status as a publicly run carrier.

U.S. Passenger-Miles

KEY: N = data do not exist; R = revised; U = data are not available.

^a Data from 2007 were calculated using a new methodology developed by FHWA. Data for these years are based on new categories and are not comparable to previous years. The new category Light duty vehicle, short wheel base replaces the old category Passenger car and includes passenger cars, light trucks, vans and sport utility vehicles with a wheelbase (WB) equal to or less than 121 inches. The new category Light duty vehicle, long wheel base replaces Other 2-axle,...

^bUrban other arterial includes other freeways and expressways, other principal arterial, and minor arterial. Rural other arterial includes other principal arterial and minor arterial prior to 2009, and includes other freeways and expressways, other principal arterial and minor arterial for 2009.

^cCollector is the sum of major and minor collectors.

Annual Wasted Fuel Due to Congestion

KEY: NA = not applicable; R = revised.

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.

Energy Intensity of Light Duty Vehicles and Motorcycles

KEY: Btu = British thermal unit; N = data do not exist; U = data are not available.

^aMotorcycle is included in Light duty vehicle, short wheel base (previously Passenger car) in 1960 and 1965.

^b Energy Intensity (Btu/passenger-mile) is calculated by converting the fuel consumption in gallons to the energy equivalent Btu units and dividing by the passenger-miles. The heat equivalent factor used for Btu conversion is 125,000 Btus/gallon.
