Note that roundabouts don't have implicit yielding rules - actually, by
default the entering traffic has the right of way, which is why you'll
see yield signs in about 99% of them.
A roundabout would be a place with one-way traffic (if there's a
roundabout sign, that's even better - easier for us). Two-way traffic
would not be a roundabout.
I haven't seen/tagged junction=circular, it might be appropriate in such
cases.
If it's a small one with a (streetcar) passable central section, that
would be mini_roundabout - but only if there's nothing obstructing
straight-through traffic.
