A revised procedure for estimating equivalent single axleloads (ESAL’s) was developed in 1985. This procedure used weight, classification, and traffic volume data collected by the Transportation Cabinet’s Division of Planning. The procedure was developed and documented as Research Report UKTRP-85-30, and was titled “Estimation of Equivalent Axleloads”. Since the revised procedure was adopted, there have been several changes; the most recent being documented as Report KTC-95-7 titled “Equivalent Single Axleload Computer Program Enhancements”. Results documented in Report KTC-95-7 included improvements in the processing of ESAL data by aggregation of the functional classes to increase the accuracy of the estimates within a class, and conversion of computer programs used to process the data from mainframe to personal computer.
