Delay Performance Measure Methodology
Delay is calculated for both directions of I-15 between Payson and Brigham City as well as in Southern Utah for all hours every day.
Normalized Annual Delay Score
The normalized delay score is determined by dividing the annual delay value by the annual target value. The target values for 2014, 2015, and 2016 would be 1,125,064, 1,849,932 and 1,886,100 respectively.
