I just returned from a 10-day driving trip in New Zealand, where the preferred traffic control method is "roundabouts." They outnumber traffic lights by a large margin throughout the country. In my experience, they work extremely well to control the flow of traffic, but they do require a different mindset.
Ms. Morehouse of the Department of Transportation (Empire, Sept. 8) is quite correct that it is dangerous to stop in the middle of the circle. The secret is to yield to vehicles that are already in the circle until you have a space to enter, and then when you see a clear space, go for it. Drive like you mean it until you reach your exit point. Once local drivers get the hang of it, it should really cut down delays on the Douglas side of the bridge. I'd like to see DOT consider more roundabouts for Juneau. They might be a good solution for some of the problematic intersections on Egan Drive and Mendenhall Loop Road.
