The idea in the OP's article is great. Anything to get drivers to obey the speed limit. I'm afraid it's just going to lead to more red light running as drivers figure out that there is no cross traffic waiting to go.
I like it, except ... with speeders triggering red it's going to happen frequently and the lights will wind up defaulting to some basic cycle. So why not simply time the lights to a lower speed to begin with, to pretty much the same effect?
It wouldn't give anybody in A&S fodder for posts.
Middle of the night cycle commuting, I want the lights along the main roads to stay green as long as possible. I do not want them turning red when there is no side street traffic.
