Humanitarian OSM Tags/smoothness
Simplified to very simple definitions of values.
- You really shouldn't do that nor propose to do that ! Because you are proposing to use an allready existing tag for a different meaning that it was proposed for, which mean the tag will be ambiguous. smoothness=bad means you can drive on it with a "normal" car, not that you can't drive over some arbitrary speed. If you want to add this information, you'd better use another tag like can_drive_faster_than_40=yes sletuffe (talk) 21:31, 17 May 2013 (UTC)
You could use surface:grade=* for that. Its value "depends" on surface=* value, that is, it isn't absolute like smoothness=*. So "Rough" could mean surface:grade=1, etc. The downside is that tag is not "official", though it has been used 1250 times as of now. --Zverik (talk) 13:18, 21 June 2013 (UTC)
