The base rate index, which excludes the impact of accessorial charges assessed by carriers, increased marginally by 0.38 percent when compared to December 2012.

Average fuel surcharges assessed by carriers have seen an increase from 19.66 percent of base rates in December 2012 to 20.36 percent in January 2013.

"Cross-border truckload saw an increase while the other segments (domestic LTL,TL & cross-border LTL) had decreases," said Doug Payne, president and COO, Nulogx, a provider of transportation management systems and the sponsor of the CGFI. "Of particular note, total costs are still trailing behind a year-ago levels."
