Except as I pointed out in my earlier post, there are more effective and safer ways to improve intersections without the need to use enforcing measures (e.g. traffic circles).
In addition, red light cameras at intersections with reasonable yellow times turn out to be unprofitable a lot of the time, which makes their use even more counter intuitive since once you remove them, people will just start running the light again. As such red light cameras are not a viable solution.
