What is a double mini roundabout?

Answer 1

a figure 8

In the UK, a "double mini-roundabout" is a type of traffic intersection where cross-traffic and right-turning traffic have been separated into two joined roundabouts ("traffic circles" to all you Americans). There is no island in the middle of each roundabout, just a circle painted on the pavement, so they can be rather compact (hence, the "mini" classification). Double-minis are more likely to be used at intersections where the roads don't meet at right angles.
