No, they say that is ONE of the defining characteristics. They have also pointed you at documentation fully describing mini roundabouts as implemented in the UK. Perhaps that was thttps://en.wikipedia.org/wiki/Roundabout#Mini-roundaboutsoo much for you to read, so here is a briefer description: So - as in my example - somebody changed a clear roundabout to > a mini_roundabout with 7 exits just because its flat in the middle. > And they expect to get the same navaids. > > So either - their understanding is wrong, the documentation is unclear > or there is no differentiation which is proper. > Their understanding is probably wrong (without seeing it I can't tell) and the documentation is unclear. The documentation you were previously pointed at, plus the link I just gave, both make it very, very clear that there is a distinction. A question which arises for me now - Why is it called roundabout > when there is no roundabout - when its just a junction. Because it IS a roundabout. A roundabout that routers can treat as a junction to save a lot of preprocessing and for which drivers (in the UK) are perfectly capable of understanding junction-type turn instructions. I'd expect a roundabout (either mini or not) to produce nav aids > in the format of "take the n.th exit" not something "left at the next > junction" > That is a language/cultural/experience difference. You say you've never driven at a mini roundabout. If you had, you might accept that "turn right" works as well as, or even better, than "take the third exit." At large roundabouts you may not have clear visibility of all the exits in order to see which one is the right turn. Some roundabouts have trees: https://goo.gl/maps/wmoA71gGUGrNTAH18 > From the document you mention i have the feeling that that is a British > special.

It's not just about traversability, size or number of exits, it's about signage and laws. In the UK a mini roundabout is signed as such and has specific legal differences from an ordinary roundabout. -- Paul
