Homer Watson and Ottawa Three Lane Roundabouts

[jamincan]

If traffic is backing up in them, it would be backing up without them too. The idea is that people who are making a right turn can bypass the traffic in the roundabout. In theory, it means that the intersection should be able to handle quite a bit higher volume than without. The ones on Homer Watson make a lot of sense, as there will be a lot of right-turning traffic there due to the highway ramps, but I'm a little surprised by the one on Alpine. Is Alpine really that busy?
