When I use the Generate Service Area Ready-To-Use tool, I sometimes get weird results. Even if I've specified "No Overlap", some of the drive time polygons DO overlap, in significantly large areas. This is particularly troublesome as one polygon can be drawing UNDER another, so it is difficult to tell where these problem areas may be.
More generally, the boundary between service area polygons from one facility to the next are not "neat" where the two service areas meet - they typically have small overlaps. This makes using the results a LOT more trouble.
Is anyone else seeing this behavior and are there any recommendations for minimizing/managing this?
