In 2007 the Bureau of Transportation Statistics (BTS), the statistical agency of the U.S. Department of Transportation, published a report entitled: Transportation Services Index and the Economy, on the relationship of the freight portion of the Transportation Services Index (TSI) to the growth cycles in the U.S. economy. Since that time, BTS has re-engineered the TSI to improve processing of the monthly data and to improve the methodology and data sources used in the calculation of the index. This report provides details on the updated methodology and data, along with the resultant changes in the turning points of the TSI due to these improvements.
