The Intermodal Savings Index (ISI), exclusive to Journal of Commerce Gold subscribers, uses proprietary data and calculations to determine how much money the average shipper will save using domestic intermodal compared with long-haul trucking (also known as "OTR"— over the road) on modally competitive lanes across the US.
The monthly data captures the shipper invoice rates on spot market and contractual loads for intermodal rail and truckload, then compares those rates to derive index values. Each lane and each region receive index values, and a weighted national US index value is also calculated.
The Contract ISI compares intermodal contracts with truckload contracts, while the Spot ISI compares spot intermodal with spot trucking rates. The index base is 100 denoting rates between rail and trucking are identical. Values greater than 100 denote intermodal is cheaper, while values less than 100 denote trucking is cheaper. The higher the index value, the more money a shipper will save on intermodal.
