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.
