Y'know, i think it might be kinda fun to close that off and hold a gymkahna event, driving around the little circles in the same order as you would tighten nuts on a 5-lug wheel...
It's an interesting solution, I suppose. Instead of making cars stop for lengths of time, you keep traffic flowing...supposedly...
We have a "Roundabout" of sorts in our town, the Historic Square. Of course, there's a problem, here.
You see, It's not meant for traffic safety. There is only one lane, and one road goes straight across one side of the loop. As well, people...um...park on the edge.

Use the street view to get a feel for the layout. It's interesting...Peoria/Walnut Street (AKA US Route 24) goes straight through the center of the circle (which has a small park in the middle, so we don't have the crossing straight over problems...if every roundabout had a fountain...) while Main street goes straight across the west side of the square. Traffic going Northbound must loop around the square.
The area is also a business district, so there's parking on all four sides of the square formed by the buildings. (hence the term, "Square") This gets interesting when wants to get into or out of a spot. Because US 24 is a major route as well, the Square is frequented by heavy truck traffic. As well, because it's a business district, Pedestrian traffic is very heavy, and all crosswalks are thus blatantly marked out.
There is a stop sign governing both sides or Main Street, while US 24 is governed by yield signs.
