[Talk-GB] C roads

[Nick Whitelegg]

As an aside, C roads are really eccentrically designated, at least if their osm tagging is correct.

e.g.

http://www.openstreetmap.org/?lat=50.9256&lon=-1.3605&zoom=14&layers=M

Re. the C351.... WTF?

I note an increasing number of roads tagged with ref=C<number>:

	http://osm.org/go/euF7qf93-
	http://osm.org/go/eu6CM0IS-
	etc.

Leaving aside for now the question of sourcing, I feel a little uneasy 
about these being rendered on the map. Anyone using the map as, well, a 
navigational aid will think "turn left onto the C94... oh... hang on... 
what C94?".

So if we are to have such arcana in the database, and experience 
suggests you can't actually stop people adding arcana to OSM (I guess 
that's one of our strengths ;) ), it would be helpful to have some way 
of tagging "this ref is not actually signed". That way, renderers and 
routers could choose not to show refs which aren't helpful for their 
audience. Something like ref:signed=no would work.

Any thoughts?

cheers
Richard
