The Department of Transportation’s Bureau of Transportation Statistics (BTS) reported this week that its Freight Transportation Services Index (TSI) declined 0.4% from December to January, the most recent month for which data is available.
According to BTS officials, the Freight TSI measures the month-to-month changes in freight shipments in ton-miles, which are then 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.
January’s Freight TSI reading at 132.3 marks its second highest level ever recorded, with December 2017’s 132.8 (upwardly revised from an initial reading of 132.0) being the highest. And January’s reading is 39.7% higher than the April 2009 low during the most recent recession.
BTS pointed decreases in rail carloads, rail intermodal, pipeline and water for the 0.4% decline, while trucking and air freight increased. Compared to January 2017, for-hire freight shipments were up 6.3% from January 2017.
