I originally proposed (or rather, started using, then proposed) the 
turning_circle tag. Looking back at what I wrote then I didn't make 
explicit what was at the back of my mind: you could use the width= tag 
to specify just how big the turning circle is. Word-based descriptions 
are ambiguous, and could mean different things depending on the type of 
road the turning circle is in.

As for turning bays, I usually map these as a short stub of highway, 
like here:
