Just warning about small traffic circles.
If they are small enough, they are easy to ride a bike through.
But they are miserable to walk through.
Unless motor traffic is rare, don’t. Unless truck traffic is near zero, beware.
(Plus they are expensive to shoehorn into
an existing intersection.)
Have way too much experience with too many rotaries of all sizes usually ineptly executed and always driven through by mad drivers. Yield? With my piece of crap car?
