What's the consensus for county roads in the US?
I don't know what the consensus is.
County roads in California are of the form [A-Z][0-9][0-9]. I tag Orange
County route S18 as:
network="US:CA:Orange"
+ ref="CR S18"
How does this work with routes that cross county lines? California has a
statewide numbering system, with the letter roughly representing the part
of the state.
Yup - that is problematic. I think, when I marked Orange County S18 last
year, I didn't see any other county road tagging to go by.
http://www.cahighways.org/county.html shows that there are some occurrences
of this. I apparently expected to break them at the county lines, I guess,
so as to agree with signage. That is, Orange County S99 would be a
different route than San Diego S99. network="US:CA:Orange;US:CA:San Diego"
on the relation seems workable.
It's almost like they defined super-groups of counties identified by
those letters. I'll have to crunch that table to see if that's the case so
we could have network=US:CA:S + ref="CR S18". Maybe add an is_in:county tag
to the individual segments to avoid losing that important info.
I realize this is kind of scattered. On my way out the door.
