What is a dog bone roundabout?

The dogbone roundabouts are employed in places where a fast arterial or highway intersects a smaller street. It's a bit like a cloverleaf interchange, but with the additional benefit of slowing and separating traffic converging at the center of the intersecting road. The diagram here explains the flow.

Is a roundabout also called a rotary?

Why are there no roundabouts in America?

Americans' aversion to rotaries started with the introduction of an old type of traffic circle in the 1910s.

How is a traffic circle different from a roundabout?

Traffic circles are larger, usually with two or more lanes, and are designed to move drivers at higher speeds. You can expect to find them on main roads and at high volume intersections. Roundabouts are smaller and intended for slower speeds. They're most common in residential areas where they're used to calm traffic.

What are the small roundabouts called?

Mini Roundabouts

These smaller roundabouts have a mountable central island, making for a smaller footprint. This allows larger trucks to drive over the central island while still encouraging most vehicles to navigate on the circulatory road surface.
