How should be tagged roundabout with multiphase traffic light?

  1. As normal street (4 one way streets) because condition "the traffic on the roundabout has right of way" (from Wikipedia) is not fulfilled.
  2. As roundabout (junction:roundabout) because before roundabout exist signposts with information about roundabout.

This place has own name (roundabout ...). Traffic is the same as on 4 crossroads near each other. Only in a situation when traffic lights is not working all drive in this place like as the normal roundabout.

Example for this situation (at google.pl/maps)

I'd map it as a roundabout because it's functionally a single junction.

I prefer roundabout too but I get info from OSM users in Poland that condition "the traffic on the roundabout has right of way" is not fulfilled in this case and I should add tags as for normal oneway streets with 4 crossroads.

In the UK these are still mapped as roundabouts, and I'm sure we had a discussion about it some years ago. Here are some local examples: http://osm.org/go/eu8Yeh_5u and (rather more complex) http://osm.org/go/eu8ZKL4yF. I think the clinching argument was how would traffic behave if the lights were not working. In the example there is a standard roundabout symbol which implies traffic on the roundabout has priority, the lights merely altering the flow.
