The Freight Transportation Services Index (TSI), which is based on the amount of freight carried by the for-hire transportation industry, rose 0.3 percent in September from August, rising for the third consecutive month, according to the U.S. Department of Transportation’s Bureau of Transportation Statistics. The September 2014 index level (121.5) was 28.5 percent above the April 2009 low during the most recent recession.
The level of freight shipments in September measured by the Freight TSI (121.5) reached its all-time high (Table 2A). BTS’ TSI records begin in 2000. See historical TSI data.
The August index was revised to 121.2 from 120.9 in last month’s release. There were smaller upward revisions for each of the previous months in 2014.
The Freight TSI measures the month-to-month changes in freight shipments by mode of transportation in tons and ton-miles, which are combined into one index. The index measures the output of the for-hire freight transportation industry and consists of data from for-hire trucking, rail, inland waterways, pipelines and air freight.
