Without looking at the intersections in question, I suspect they could
be traffic calming circles. These are common in residential areas.
They're frequently uncontrolled and unsigned and the purpose of them is
to slow down traffic, not to improve traffic flow like a roundabout.</div><div><br></div><div>I agree with Albert that junction=circular is the way to go. However, I'm unsure of whether it would be better to just tag the intersection node or draw out the circle and add 4 nodes as the wiki seems to suggest. I think you can argue it either way, there's technically a roundish right of way, but all of the ones I've seen are basically a hole cut in the middle of an otherwise straight intersection. Sometimes the circle is small enough that you can swerve around it if you're going straight. It's not something I've tried to map before so I haven't given it much thought.<br></div></div></blockquote><div><br></div><div>The location Marian provided all look like roudabouts but without any directional arrows in the pavement. Seattle has a bunch of island calming intersections that I've mapped in the past with just a node at the intersection.

I believe that the city ordinance allows for left turn without going through the circle. </div><div><br></div><div>All of the examples Marian gave I would map as a circle with a oneway=yes along with a note for help from a local mapper to verify. Going one way in the circle wouldn't be wrong, but making it two way could be wrong. </div><div><br></div><div>Best,</div><div>Clifford</div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div></div></div></blockquote></div><br><div dir="ltr" class="gmail_signature"><div dir="ltr"><div>@osm_seattle<br></div><div><a href="http://osm_seattle.snowandsnow.us" target="_blank">osm_seattle.snowandsnow.us</a></div><div>OpenStreetMap: Maps with a human touch</div></div></div></div></div></div>
