| This controls the supersegment creation based on PCI.  The tolerance is a range of acceptable PCI values.  As the supersegment is created the average supersegment PCI is calculated.  The PCI tolerance range is calculated using the following formula. Supersegment Average PCI + PCI Tolerance AND Supersegment Average PCI - PCI Tolerance. Each new subsegment's PCI is compared against the supersegment's average PCI.  If the subsegment PCI falls outside that range the supersegment is completed and a new supersegment is created.   This helps with a subsegment that is either in really good condition, or really bad condition from being added to a supersegment of subsegments that are in average condition.  This helps to keep roads that are going to require the same maintenance grouped together.  For example:  If the average PCI of the supersegment that is being created is 75 and the PCI Tolerance is 10 a subsegment with a PCI 70 will be included in the supersegment, while a subsegment with a PCI of 60 will cause a new supersegment to be generated. |
