Simple domination doesn't seem like an adequate explanation. Is it the case that the dominant traffic pattern effectively monopolizes the roundabout making it difficult for other traffic to enter for significant periods of time?
- switch007 12y agoYes. It's also an issue of the traffic traversing the roundabout at great speed, making it very difficult to join. I don't understand why they don't add traffic signals to the problem roundabouts, operated when required. It would seem less disruptive.
- kencausey 12y agoThat sounds like a poorly designed roundabout to me. One recently added to my relatively small city has a speed limit of 20 MPH (yes, I'm in the US) and much more than 20 MPH seems too fast to me simply as a result of the radius of the roundabout.
- SixSigma 12y agoIt is routes such as ring roads where effectively it is a crossroads with one of the crosses being 4-6 lanes wide at 40mph and the other being 2 lanes approaching at 30mph, (though not always such a speed disparity). So if you arrive from the 2 lane 30mph road you could have a very long wait time.
