The LoDI Index

National LoDI Index

Greater Louisville LoDI Index

The National LoDI Index for April 2018 is 60, which shows an increase from the March index value. Though crude oil prices have been increasing slightly in recent months, all of the traffic volumes have also increased showing an uptick in activity for the sector. This rise in activity is expected to continue, as seen by this increase in the index. The value for April 2018 is the highest value of this year, and it is also the highest value seen for the month of April in recent years.

The Louisville LoDI Index for April 2018 is 66. This value is lower than March’s index value. Since the holiday season has passed, air traffic volumes have (expectedly) decreased in recent months. Crude oil prices in the Greater Louisville Area also increased slightly during this time. This combination of events has led to the index value’s decrease. The Local LoDI Index value for April 2018 is the highest value for the month of April 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!
