The index has risen 15.5 percent since April 2009’s low during the recession.
The TSI reached an all-time high in December of 2011, and November’s reading was 4.5 percent below that.
The Index is a compilation of data from trucking, rail, inland waterways, pipelines and air freight and measures monthly changes in freight shipments in tons and ton-miles.
BTS says that November received a push from rebuilding and recovery efforts in the Northeast from Hurricane Sandy, which had squashed freight for truck and rail in October.
