The Bureau of Transportation Statistics (BTS) today released an update of its Government Transportation Financial Statistics (GTFS), with data through 2020.  GTFS provides a set of maps, charts, and tables with information on transportation-related revenue and expenditures for all levels of government, including federal, state, and local, and for all modes of transportation. The update is available at https://www.bts.gov/gtfs.

State, local, and federal governments play an important role in the U.S. transportation system, as providers of transportation infrastructure and as administrators and regulators of the system. In 2020, government spending in the U.S. on building, rehabilitating, maintaining, operating, and administering the transportation system totaled more than $400 billion. GTFS captures this spending and revenue and helps users understand these considerable inflows and outflows.
