NOTE: TSI is updated monthly. The index numbers for the latest three months are considered to be preliminary. BTS releases the preliminary number for the latest month and replaces the number for the oldest preliminary month with a revised number. Seasonal adjustment models for the modal data have been updated for the data January 2000 to the present. The earlier data (January 1990 to December 1999) were adjusted with the older seasonal adjustment models, which may result in a discontinuity in the time series.

TSI numbers are BTS estimates.
| The Transportation Services Index (TSI), created by the U.S. Department of Transportation (DOT), Bureau of Transportation Statistics (BTS), measures the movement of freight and passengers. The index, which is seasonally adjusted, combines available data on freight traffic, as well as passenger travel, that have been weighted to yield a monthly measure of transportation services output. |
