I recently performed ArcGIS Location Allocation for a layer of census population data and a layer of facility destinations. Before this, I discerned the service area of these destinations with Create Service Area. Service Area however does not consider the capacity of the facility in the way the Location Allocation did; therefore, the service areas really aren't super accurate. Now that I know to where each demand point is allocated, I would like to create a say "drive zone" polygon around the facility based on its true demand. I can't however figure out how to do so. I do not necessarily need these polygons to have any detailed information associated with them, I just need to compare what Create Service Area polygons look like against this more realistic service area. I have ArcGIS 10.3 to work with.
Any insight is appreciated!
