Roadway Design - Quad Left Turns
Roadway Design - Quad Left Turns
(OP)
Hi All,
I am looking for information regarding the use of quad left turns in roadway design; specifically, existing examples of quad-lefts, pros and cons of design, traffic studies/analysis, etc. So far, I have come across a few examples from New York, China, and Ohio as well as an example of a double-double right turn in Jacksonville, FL. Unfortunately, the quad left in NY was changed to a triple left in 2010 and I have not found an explanation, as yet.
Any information and guidance is greatly appreciated!
