The American Trucking Associations (ATA) advanced seasonally adjusted for-hire Truck Tonnage Index increased 0.6 percent in January, marking its fifth consecutive monthly gain, according to ATA.
ATA recently revised the index back five years, which resulted in a slightly stronger 2005 performance than previously reported.
The index grew 2.3 percent compared with 2004 rather than 2.0 percent as originally reported.
December’s tonnage level, meanwhile, actually increased 0.2 percent instead of falling significantly.
Each year, ATA revises the index back five years as part of its annual calculation for the upcoming year’s seasonal factors.
January’s improvement pushed the seasonally adjusted index to 118.0, the second highest level on record.
Compared with January 2005, the index was 3.2 percent lower. The not seasonally adjusted index rose 1.4 percent from December 2005 to 109.0.
