There isn't. A roundabout is always one way. If there are two directions
it is not a roundabout but a circular road.
Just after sending this I realized that I must have misread your
question. You mean why most roundabouts are made up of more than one way.
Initially it is because of the AND import. The AND dataset was such that
between every junction of 3 or more roads there was a sperate way.
What means the AND dataset?
Now it is just convenient if you have different relations (like a bus
line) over the roundabout. Then you can indicate exactly which side a
relation takes.
Well, this is really not necessary because you drive the roundabout
alwas in the same direction.
In Germany we only have roundabouts made of ONE way. If you use the
relation-editor of JOSM, than you can easily recgnize a roundabout.
Would it not be easier, to use only ONE way in a roundabaout?
