How to delete not quite duplicate geometry

JohnPapageorgiou

Hi,

I hope I'm posting this in the right area, I figured transportation specialists might have valuable insight into this problem.  We have two road shapefiles with thousands of features.  Some roads in either shapefile are the same road, but their geometry is not exactly the same.  We want to remove these potential spatial duplicates.  Delete identical will not work because there may be instances where spatially the "identical" lines do not have identical geometry, and we don't want to delete based on attribute data, because it may be necessary to have several segments with the same name.  Is there a quicker way to solve this problem rather than manually examining each line/comparing and deleting?  Is there a topology rule that can be used to help in this process?  Is this something that can be done through linear referencing tools?  Or do I need network analyst? I am using ArcGIS 10.3.1 Advanced. With Spatial and 3D analyst extensions. 

thanks,

John

I only have one of the two feature classes and yes in the SHAPE field is says "Polyline M" and it also has a Shape Length field.  We are getting these feature classes from two different big organizations, so I think it is safe to assume that the other feature class would have the same setup.
