This example is a full-stop roundabout in Hawthorn Woods. The distinct feature that makes it different than a modern roundabout is that on each leg there are stop signs. You can see the white stop bar on each entrance into the circle. This is similar to a modern roundabout, but does not provide the traffic flow efficiency of a modern roundabout. This is basically a four-way stop intersection with a landscape median. Communities usually implement this style of intersection as a method of traffic calming.
