Any such thing as a roundabout junction?

Obviously CD you're being contrary soley for the sake of sophomoric kneejerk reactionism.  The roundabout's purpose is exactly what I stated.   [quote user="CrazyDiamond"][quote user="DSchmitt"] Posted by CrazyDiamond "FM, you're wrong about the purpose of steeet roundabouts......there are many ways to prevent right-of-way conflicts.....a roundabout's sole purpose is to allow very high-capacity traffic flow of an intersection where signs and/or signals would bottleneck the intersection AND where space is too limited to build a conflict-free interchange."

I read through that info a couple of years ago.  I didn't say roundabouts don't reduce points of conflict.  I said that is not its purpose which is what FM said. Reducing conflict points is a benefit of roudabouts, a safety benefit to be specific, but that is not its purpose. When space is available engineers will often choose an interchange over a roundabout...unless the space is just not there. [quote user="futuremodal"] The purpose of a street roundabout is to prevent right of way conflicts by forcing all traffic to move one circular direction.  For railroads, if the purpose is to avoid at grade diamond crossings, it'd be a lot cheaper to construct an elevated grade separation than some mile wide circle of tracks.  And yes, a lot less real estate.
