[Talk-us] Duplicate Ways (or portions of ways)

Is there a standard way to identify and remove ways that are duplicates (or
portions which are duplicates)?  These are cases where 2 ways use the same
set of nodes (or similar common subsets of the nodes) with very similar
attribution.

Examples I found in a Pennsylvania extract (just a few of many cases):

https://www.openstreetmap.org/way/11875906
https://www.openstreetmap.org/way/11999747

https://www.openstreetmap.org/way/11877460
https://www.openstreetmap.org/way/12011268

https://www.openstreetmap.org/way/11876410
https://www.openstreetmap.org/way/12001800

I've been away from the OSM world for a bit so pardon me if I missed prior
discussion on this topic.
