There was a discussion about this on the radio. I wish they had posted the whole interview and call-in show. The diverging diamond was referred as an affordable alternative to building elevated roads. The proponent of the system said it isn't the best solution but it was relatively inexpensive to build, making it possible to use it at more intersections.
