Saves money on traffic lights. Actually I like roundabouts far better then regular intersections. In the Raleigh area there is a multitude of stop lights about every 100 ft. Since the traffic is quite heavy, many of the lights stay red or green for 2.5 minutes each. That includes straight ahead travel, left hand turns at each light (separate). You can spend up to 10 minutes at each intersection, but, when you do get a green it doesn't matter where you are in line, you will make it through.
On the traffic episode of MythBusters they found that roundabouts are 20% more efficient. That's a significant difference. It makes me wonder why we don't utilize them more.
