Hi Colin,
yes, I think for most drivers the destinction between the two types is not needed. I guess that a routing software specilized for large vehicles would also be able to interpret the circular shape like a highway=passing_place.

In the UK (where there are lot of mini-roundabouts) you are expected to drive "around" a painted mini-roundabout, and not "over" it, unless the size of your vehicle makes it impossible to do otherwise. So I see the main difference being in the way they are tagged in OSM: circular way with junction=roundabout, or a simple node with highway=mini_roundabout. The radius of the roundabout is not involved in the distinction, only the way it is mapped. In NL there are many small roundabouts with a proper round obstacle in the middle, but different surfaces for the inner "lane" and the outer "lane" such that you are subconsciously led to follow the outer lane. There is no actual barrier or law stopping you using the inner lane however. These roundabouts are almost a hybrid between grown-up roundabouts with the central obstacle, and mini-roundabouts with no physical obstacle at all.

However, there seems to be a need to draw a circular way instead. See my discussion with ij_ http://www.openstreetmap.org/changeset/11603397#map=16/60.2119/25.1869 I found a few cases where mappers added mini_roundabout=yes as an attribute, I'd also be happy with e.g. center_barrier=no or just barrier=no as an attribute on the ways which make up the junction=roundabout. I also saw a few junction=mini_roundabout on circular ways. Why not? Your thoughts?
