If your intersection is busy enough to justify some of these rather large and expensive intersection designs (like #5 and #13 from the article) -- then you might as well spend the cash to make it into a real freeway interchange and have zero intersections or stoplights at all. That will handle even more traffic, be even safer (by their geometric conflict metric), have no stoplights for drivers to deal with, and no one has to learn anything new to navigate it safely.
