I grew up in New Jersey and had six traffic circles within 10 miles of my home.
Today there are none.
You had to practically fight your way into and out of the circle, the greater majority of people did not have the skills to make them work correctly. Further study on this issue is more than warranted. The jug handle takes traffic straight through an intersection, then allows a series of right-turns into the cross street. Proper turn-laning eliminates the need for Stop signs at the turns. Florida Transportation officials would well advised to study the jug handle.
