[Talk-us] United States Roadway Classification Guidelines

[McGuire, Matthew]

This looks like coding for the map rather than mapping what's on the ground. I understand that a highway's importance to an area is relative to other highways in the area.  But that doesn't mean a two lane at-grade highway should be coded the same in one area as a four lane limited access highway in another. Or perhaps there should be another tag for the type of road as experienced on the ground vs a state or national scale map.

Are you responding to a different proposal?

No. The proposal linked here suggests that mappers tag roads classified by the government with certain highway= tags. My suggestion is that if we are going to tag roads based on government classification and not follow the highway tag guidelines on the wiki, then we should use a different tag name.
