The LoDI Index

National LoDI Index

Greater Louisville LoDI Index

The National LoDI Index for August 2017 is 57, showing no change from July’s index value. Though the volumes of some transit modes decreased slightly, low crude oil prices bolster the index value back to its previous level. This value for August 2017 retains the highest index value for the year, and is the second highest value seen for the month of August in recent years.

The Louisville LoDI Index for August 2017 is 63, showing a slight decrease from last month’s index value.  Decreases in rail and river traffic volumes caused this change. Crude oil prices remained steady at the local level and other traffic volumes in the Greater Louisville area were also stable in recent months. This index value is the second highest value for this year, and is the highest value seen for the month of August in recent years.

The LoDI Index was developed at the Logistics and Distribution Institute (LoDI) at the University of Louisville and launched in early 2012. The index comes in two varieties; one specific to the Greater Louisville area, and another pertaining to the United States as a whole. Each index has the same purpose for its target area; to predict the level of logistics and distribution activity for the upcoming month. As a predictive indicator, the LoDI index can help organizations related to the field of logistics and distribution in making educated decisions related to projects, expenditures, and other associated activities, ahead of the curve.

The index utilizes regression analysis forecasting techniques. Multiple factors relating to the field are incorporated into the index’s calculations. Data includes factors relating to four main methods of transit: air, trucking, railway, and barge; as well as other economic factors. The indices are reported as a number between 1 and 100. The higher the index value, the higher the level of predicted activity. An index of 50 represents a level of activity equivalent to the established base year levels.

Future research is planned to incorporate additional indices related to the field of logistics and distribution into the LoDI Index family. Updates to the original Greater Louisville index have recently be completed in an effort to maintain as much predictive power as possible. Stay tuned for our upcoming work!
