I was away most of last month, and missed most of the discussion of mini
and normal roundabouts. However, looking at the wiki now, from what I can
tell the differences now are
-Roundabouts can be mapped as a way or node (though way is preferred), mini
roundabouts only as a node
-Roundabouts
IMO tagging a mini - no matter how large it is - as a way would be
inconsistent with our way we map (most?) features. When mapping a
street, we draw the way where one can drive/go. On a normal roundabout
you can not drive in the middle, that's why we map it as circle. We

Diameter is more universally understood by the layman than radius. Radius is
normally only used by engineers, scientists and mathematicians.
Plus it keeps us from having to map fractions.

It is. It is a perfect circle on a frictionless plane.
But if it's not, use the minor radius, then calculations can be done for the
worst case (large vehicle, smallest

I missed the point that the miniroundabout would be drawn as a circle
(area). Then why talking about tagging radius/diameter when you have
the information in the geometry ?
I think it is micromapping like drawing normal highways with
rectangles instead of lines. It's experimental and not very

IMOH the only problem I see is the key highway= . Why not changes this
to junction=mini_roundabout and draw a circle with
highway=primary/secondary... and add area=yes.
A side affect would be that all minis will be rechecked.

Mini roundabouts are normally too small to be anything but round.
I realise that we would use decimal s rather than fractions. But in most cases
a guestimate of diameter in metres will do. Most will be either 1, 2 or 3
metres, using radius there will be a lot that are radius of 0.5m.

ah, so you are talking about diameter of the center usually not
traversed section.
i suspect that using diameter to mean ID will be error prone as some (many?)
will assume it means the OD of the mini-roundabout.

I would map that as a mini-roundabout node, since the center median
