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. |
