Freight Analysis Framework Historical Series - The Bureau of Transportation Statistics (BTS) has released a historical series of Freight Analysis Framework (FAF) data that allows users to analyze freight flow trends from 1997 to 2045 by using a combination of this new historical series, recent annual data, and long-range forecasts. The FAF uses base years with five-year intervals corresponding to the years in which the Commodity Flow Survey (CFS) is conducted. The newly-released historical series uses data from the most recent base year of 2012 to adjust the previous FAF base years of 1997, 2002, and 2007. The data for these earlier years have been adjusted to align with the standards of the current generation of the program (FAF4). The historical data enable transportation planners, transportation researchers, and academics to make more informed decisions about the future by having context about the recent past. The FAF program is jointly administered by BTS and the Federal Highway Administration. The full array of FAF products is now available, including data for the previous years, geospatial network and truck flows, ton-miles, and the newly released historical series.

National Transportation Atlas Database Summer 2017 Update - The U.S. Department of Transportation’s Bureau of Transportation Statistics has released the Summer 2017 update to the National Transportation Atlas Database (NTAD). The NTAD is a compilation of geospatial data sets representing the nation’s transportation infrastructure, containing roadways, railways, and airports. Reference boundary files from other government agencies are also included. In this new update, the rail network data set has added 24 additional features, or 46 more miles. A total of 19,765 airports (an increase of 238 facilities from the last release), and other aviation facilities, are included, with enplanement and passenger data for the large airports. Incorporated in this update are 163 more water ports relative to the last release, totaling 23,598, as well as docks, marinas, and other port facility types. The NTAD, including newly updated data sets, are available for download in Excel, Keyhole Markup Language (KML), and shapefile formats, through the BTS geospatial data catalog. Additionally, Open Geospatial Consortium (OGC) standard Web Feature Services (WFS) are available for most NTAD data sets. BTS now uses a dynamic NTAD publication cycle, making updated data available throughout the year when they become available from their respective government agencies.
