How much land will a typical roundabout require?

60% increase in ROW.

Bob, what is your source on this?
The general description (I'll dig out the ref) is something like this:

A roundabout requires more space within the intersection.
A signal intersection requires more space leading up to the intersection when there is a right turn lane.
The total difference may be nil.
