Some were, there are two intersections in Georgia, one is Windy Hill Road and I forget the other but it is in Gwinn ette county where they had real numbers to show the crashes went down. Windy Hill was just damn nasty and its a big intersection. I still prefer those where traffic is only going one direction.

Still I do think many are in place only for revenue, much like speed limit cameras. I would rather see red light cameras than speed limit cameras, however I want the later to come only under specific circumstances with full public accounting. I think if they really want to sell us on safety it should all go to charity.
