Cities making red-light cameras more profitable by making them less safe

Red light cameras cause more accidents, and not just because drivers slam their brakes to avoid getting a robo-ticket -- also because the optimal money-making strategy for red-light cams is to make them less safe.

If city planners want to reduce traffic accidents at intersections, the best practice is to make the yellow last longer and insert a pause between the red signal on one side and the green on the other. However, if the objective is to make as much money as possible from red-light cameras, the best thing to do is shorten the yellow signal, eliminate the pause, and enrich the city coffers (even as you kill its citizens).
