I ran into this problem when I wanted to show road segments' total volumes as one single label for each segment, but our feature class has features for both directions of the roadways with separate volumes for each direction.
Is there a way to sum together the PCE_VOLU_3 field for each feature with the same attributes for the NO field? Any scripting solutions(python would be preferred)? I figured out a way to accomplish this in Excel by creating a formula by identifying cells, but I would much prefer to find a way to accomplish this in Arc map.
Any help would be appreciated.
