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. > On Fri, Sep 7, 2018 at 2:37 PM Marian Poara <marian.po...@telenav.com > <mailto:marian.po...@telenav.com>> wrote: > > Hi all,____ > > We have a short but important question: should we tag with > “junction=roundabout” the circular intersections in US where there > is a physical center you can’t drive over and there is more than one > way entering, based on satellite imagery?
