Mythbusters Adam & Jamie test the efficiency of roundabouts vs stop signs.
This video is about 10 minutes long. Although, the roundabouts were not two lanes like here, the result were pretty clear.

unfortunately since there ARE 2 lanes in the roundabouts here the test is not valid. That's basic to testing a scenario, apples to apples not oranges, this test does not meet scientific method basic criteria if you try to apply those results here. sorry. our numbers would probably be significantly higher for throughput
