Over at Car Gurus, there is a post about a traffic flow design concept which eliminates left turns at intersections. Called a "superstreet", the design prevents cars from crossing a major street, and instead do what is known around here as a "Michigan Left".
From the NCSU study on the subject:
“The study shows a 20 percent overall reduction in travel time compared to similar intersections that use conventional traffic designs,” says Dr. Joe Hummer, professor of civil, construction and environmental engineering at NC State and one of the researchers who conducted the study. “We also found that superstreet intersections experience an average of 46 percent fewer reported automobile collisions – and 63 percent fewer collisions that result in personal injury.”
I like it.
