Hard to Put Red-Light Violations Under a Lens

An interesting article from today's Wall Street Journal, Hard to Put Red-Light Violations Under a Lens.

Nothing new here, some data shows the number of accidents increase at Red Light Camera intersections because of people slamming on the brakes to avoid a ticket, but the cost of those accidents is less than typically accidents resulting from someone running a red light.

Here's a novel idea though, why not lengthen the yellow light time?  As the article states, this lessens the number of people running a red light and gives people more time to brake before the light turns red.  This would reduce red light accidents, but then the city wouldn't be able to generate their millions in revenue from people who do rolling stops when they are turning on red.
