Red-light cameras don't reduce the number of traffic accidents or injuries at intersections where the devices are installed, according a new analysis by Case Western Reserve University.

Touted by supporters as a way increase public safety by ticketing drivers who continue through red lights, the cameras actually shift traffic patterns: More drivers tend to brake harder and more abruptly, increasing fender-benders and other so-called "non-angle" collisions.

"Once drivers knew about the cameras, they appeared to accept a higher accident risk from slamming on their brakes at yellow lights to avoid an expensive traffic citation—thereby decreasing safety for themselves and other drivers," said Justin Gallagher, an assistant professor of economics at Weatherhead School of Management at Case Western Reserve.

Accidents didn't decrease, only shift.

    On the contrary. Red light cameras work so well that the municipalities have been able to reduce the duration of yellow lights, thus giving traffic more time to move. It's also been found to increase revenue for local auto body repair shops, so win-win.

    Increasing revenue to body shops is not a net increase in the economy. That money spent at body shops could have been spent on something else. It is merely a diversion of resources to something that does not improve humanity as a whole. Creating artificial destruction so that you can fix it. That is EXACTLY the type of thing that government is supposed to do. So I guess they're doing their job.
