[OSM-talk] ref in roundabouts

[Dermot McNally]

I'm also against tagging a ref on roundabouts unless it refers
specifically _to_ the roundabout, rather than to one of the (by
definition) several routes passing through. The very fact that we tag
roundabouts with a junction tag emphasises their role as "neutral
territory" owned by none (or all, you decide) of the roads feeding it.

I've seen arguments in favour of tagging with the ref of the most
major through route, but I don't find that compelling. Certainly, you
could consider that a roundabout without a ref would create a
discontinuity in the through route, but my view is that the junction
tag is special and that such discontinuities don't count.
