Freight Analysis Framework Version 4 (FAF4)

Friday, April 26, 2024

About the Freight Analysis Framework

The Freight Analysis Framework (FAF), produced through a partnership between the Bureau of Transportation Statistics (BTS) and the Federal Highway Administration (FHWA), integrates data from a variety of sources to create a comprehensive picture of freight movement among states and major metropolitan areas by all modes of transportation. Starting with data from the Commodity Flow Survey (CFS) and international trade data from the Census Bureau, FAF incorporates data from agriculture, extraction, utility, construction, service, and other sectors.

FAF Version 4

FAF version 4 (FAF4) provides estimates for tonnage, value, and ton-miles by regions of origin and destination, commodity type, and mode. Data are available for the base year of 2012, the recent years of 2013-2018, and forecasts from 2020 through 2045 in 5-year intervals. Data may be accessed through the downloadable databases.

Regional Database of tonnage, value, and ton-miles by FAF regions of origin and destination, commodity type, and mode. Data are also available for optimistic (“high”) and pessimistic (“low”) growth scenarios. Weights are in thousands of tons, activity is in millions of ton-miles, values for the full time period covered (2012-45) are in millions of 2012 constant dollars, and values for recently completed years (2013-18) are also available in millions of current dollars. Files are available in .csv and MS Access formats.

State Database of tonnage, value, and ton-miles by states of origin and destination, commodity type, and mode. Data are also available for optimistic (“high”) and pessimistic (“low”) growth scenarios. Weights are in thousands of tons, activity is in millions of ton-miles, values for the full time period covered (2012-45) are in millions of 2012 constant dollars, and values for recently completed years (2013-18) are also available in millions of current dollars. Files are available in .csv and MS Access formats.

Historic Series Database of tonnage, value, and ton-miles by states of origin and destination, commodity type, and mode. Weights are in thousands of tons, activity is in millions of ton-miles, and values are available both in millions of 2012 constant dollars and in millions of current dollars. Data for earlier years is only available at the state level, and all fields are defined by FAF4 standards. Files are available in .csv format.

A single .csv file at the regional level of geography with each data element in a single column is available here (346 MB). This file covers 2012-2045.

A single .csv file at the state level of geography with each data element in a single column is available here (116 MB). This file covers 1997-2045.
 

Network Database and Flow Assignment

The FAF Network Assignment estimates freight volumes and truck movements over the nation's highway network. The network is available in both ESRI and TransCAD formats.
 

Schedule of Releases

Version 4.5.1 is the last data release for FAF4. The next generation, FAF5, is under development and will have products released beginning late 2020. The initial data product will be the base-year matrix built using estimates from the 2017 CFS. A follow-up release will have forecasts for 2025-2050, as well as annual data for 2018 and 2019 rebaselined to 2017. Other 2017-based data products will follow.
