Yup. Amherst. Pretty little town.
I think the circles work best where there’s a modest but fairly constant traffic flow in both directions. Then there’s a rhythm to them that makes sense. There’s a town near here with one on each side of a freeway overpass, but it’s not a heavily traveled freeway, and there’s a Wal-Mart on one side and a retail strip on the other, and the circles move things along fine.
Love roundabouts...Lived in England for three months, and after getting used to them, it was great for not having to stop or get stuck behind red lights. But as mentioned, there are not good for every place. High traffic, multi lane intersections may not be good. I see these working better for simple road intersections in the suburbs. Saves on the cost/maintenance of a traffic light, plus it looks better. Not everything European is bad...
