The Bureau of Transportation Statistics (BTS) released the first version of county-to-county commodity flow dataset based on 2022 Freight Analysis Framework (FAF) commodity flows. This experimental product includes estimates of county-level freight tonnage for the year of 2022 for five commodity group and five modes. The five commodity types are aggregated based on the 42 original commodity code in FAF5.6.1. The four modes include truck/air, rail, water, multiple modes and mail, and pipeline. The experimental product includes two sets of files for users to test and explore:

• State-specific files: 51 files containing data for 50 states and Washington, DC. For each state, the datasets include county-level detail for the state and all adjacent states; and FAF zone-level detail elsewhere. Each state-level file contains four files: 1) flows in the state of interest and all adjacent states, 2) flows from the multi-state area to all other FAF regions, 3) flows from all other FAF regions to the multi-state area, and 4) FAF zone-to-FAF zone flows for all other FAF areas. 
• County-level origin and destination factor files: files containing county-level disaggregation factors by mode and commodity group for all U.S. counties. 

The experimental downloadable product files, technical report, and user guide are available at https://www.bts.gov/faf/county. The state-specific files are designed for planners and researchers to conduct analysis of county-level freight flows in a region. The full set of disaggregation factors allow users to merge the datasets with the FAF data to create the county-level commodity flows for the whole country or for geographic areas of interest.
