Additional Information
Accumulated attribute values are reported in output fields with the format Total_[AccumulateAttributeName]_[TimeUnits] and Total_[AccumulateAttributeName]_[DistanceUnits], where TimeUnits and DistanceUnits are the time and distance units specified for the analysis. The script sets odcm.timeUnits = arcpy.nax.TimeUnits.Minutes and odcm.distanceUnits = arcpy.nax.DistanceUnits.Miles, and it accumulates the cost attributes Miles and Minutes. As a result, the output includes fields named Total_Miles_Miles and Total_Minutes_Minutes, which is the expected behavior.
