This report provides timely and easily accessible information for the transportation community. It was developed by the Bureau of Transportation Statistics (BTS) of the U.S. Department of Transportation (DOT), and is updated every two months on the BTS website.
The indicators fall under two broad categories: those that provide context about the economy and society in which transportation functions, and those that convey information about an aspect of transportation. These latter indicators are either transportation-wide in scope or apply to a specific aspect of the transportation system.
For indicators that are highly seasonal, the current value of that indicator is compared to the same time period in the previous year (e.g., April 2009 compared to April 2008). Otherwise, the tables show a comparison of the current value to a comparable preceding period of time (e.g., the data for the month of April 2009 compared to that of March 2009).
NOTE: This report replaced the Transportation Indicators which was last published in December 2002.
