[Tagging] tagging of a throughabout

[Lukas Sommer]

Hello.

How do I tag correct a Hamburger roundabout/throughabout/cut-through (see
http://en.wikipedia.org/wiki/Roundabout#Hamburger_roundabout.2Fthroughabout.2Fcut-through
for a description).

My thoughts: The OSM wiki describes a roundabout at
http://wiki.openstreetmap.org/wiki/Tag:junction=roundabout with these
points:

– where the traffic goes around a non-traversable island (or a void in case
of elevated roads) in the middle

– the traffic on the roundabout has right of way.

Both conditions are not true for hamburger roundabouts/throughabouts. So I
would say that a hamburger roundabout – in spite of its name – is not a
roundabout, but a traffic circle (see
http://wiki.openstreetmap.org/wiki/Tag:junction=roundabout#Possible_misinterpretations
for details).
Consequently they are not tagged with junction=roundabout, but like normal
roads or carriageways (and using turn restrictions where appropriate).

Am I right?
