U.S. Bureau of Transportation Statistics
The Bureau of Transportation Statistics' monthly Transportation Services Index (TSI) with its seasonally-adjusted underlying series (Socrata dataset bw6n-ddqk, https://data.bts.gov/resource/bw6n-ddqk.json). Each row is one month: the combined, freight and passenger indexes (tsi_total, tsi_freight, tsi_passenger, chained 2000 = 100) plus monthly changes, alongside the component series - air revenue passenger and ton miles, rail carloads/intermodal/passenger miles, transit ridership, pipeline movements, waterborne tonnage, truck tonnage index and vehicle miles traveled. Method: BTS aggregates for-hire transportation output; '_d11' columns are the seasonally-adjusted variants. Units: index points for tsi_* (base year 2000 = 100); component units are given per column (thousands, millions of short tons, billion cubic feet, etc.). Caveats: the latest 2-3 months are routinely revised as source data finalizes. Coverage: United States, 2000-01 to the present, monthly. Provenance: BTS keyless Socrata API, U.S. public domain - please cite the U.S. Department of Transportation, Bureau of Transportation Statistics. Primary key: obs_date (first of month). Cadence: refreshed monthly. Nullability: recent months may have nulls where a component series is not yet published. Sample use: plot tsi_freight against time as a coincident gauge of U.S. goods movement.
