OpenStreetMap

Road Weary

Posted by Boondoggle on 29 January 2011 in English.

I've started labeling the county roads in Telfair and Wheeler. It needs to be done; it should be done. That's what led me to OSM in the first place. However, as T.S. Eliot penned about cats, the naming of roads is a difficult matter and isn't just a holiday game. And it seems that the roads in these two counties must have three or more names as well.

The problem is that until a short time ago the roads were not names at all, other than informal names that could vary from one end of the road to the other. For instance, there were two roads called Firetower in Telfair, and which you meant depended on which side of the county you were in. As with many counties in Georgia, the roads received an offical name only with the advent of a 911 system. And that should be the end of that, right?

Wrong. First of all, the 911 road name may or may not agree with the signs - where signs exist. The sign name sometimes doesn't agree with the name the US Postal Service says is the correct 911 name. And, to top it off, the Georgia Deparment of Transportation seems to have a different set, as evidenced by their signs preceding the intersections. That's the current set, by the way: The road use maps for both counties show pre-911 system names. Quite a bit of "fun."

However, there is one common denominator. Reguardless of the name, the county road number remains the same. Sometimes this is still posted on the back of the stop signs; sometimes it's posted in tiny characters on the official road signs. But it's the only consistant point.

With that in mind, here's my approach to editing the roads:

1. Go with the road sign name, where available.
2. Add or edit the name_1 tag so that it contains the correct county road number.

That way, even if there's confusion over the official name, anyone who checks can be certain of the road by checking its county number.

They list local names, regional names, official names, old names, national and international names.

Would the ref key be of any use to you for recording the numbers?

http://wiki.openstreetmap.org/wiki/Key:ref

I suppose the only issue would be if any of the roads are also part of a numbered route. loc_ref or reg_ref?

I'm not sure about the ref key. Perhaps that's the way to go. On the other hand, some county road numbers already show up in name_1.

I'd probably use reg_name for state highways, loc_name for county highways. Or of course name if it only has one name.

ref would be its normal number, use nat_, reg_, loc_ when it may have two or more a good example would be an Interstate that is also a US Route...

Fictitious examples
name=Interstate 12
ref=I 12
alt_name=United States Route 82 (possibly nat_name might be better)
alt_ref=US 82

name=Bob's Road
ref=GA 123
loc_name=County Highway 12

I now think that ref should be used, as davespod suggested. A few roads were already set with the County Road number in ref, and they render well. This allows both the official name and the County Road number to be displayed simultaneously. Another ref plus is the ability to use multiple road numbers separated by a semicolon. Very handy for our state and federal highways, which overlap.

Right or wrong, I'm also including "CR" for county roads, and "SR" for state routes. This is nomenclature long used by the Georgia Department of Transportation, and I think will weed out confusion. Just adding "27" in the ref tells nothing, and federal roads imported from TIGER have the US prefix in the ref tag.
