My own two cents, based on living for many years in Washington, DC: at low traffic volumes, traffic circles work well. At high volumes, they can become congested. Am I wrong to be surprised that Minneapolis rates among the top 20 cities for bicycling? I would think that bicycling there would be uncomfortable in the winter, and that the loss of lane width to snow would might make it risky.
