There are many; the supermajority show that the cameras do increase the number of rear-end accidents at intersection.
Other studies show that if the concern is T-bone accidents at intersections, *lengthening* the yellow light at an intersection actually reduces accidents an average of about the same amount as the best case presented for the cameras. Cost to city: $0.
These cameras are ALL about revenue.
I’ve seen those other studies. If it was about safety, the yellow light can be lengthened a minute amount and make a huge difference. But, as you said, this is about revenue.
Recently I watched six cars make their left turn after the light had changed to red.
There are legitimate concerns about the way people “obey” traffic lights.

I recall reading a study that stated "lengthening the yellow lights 2 seconds decreased accidents by almost 50%".
I believe that study was paid for by the insurance industry. Their reasoning that fewer claims paid out for rear end collisions where red light cameras were located and fewer T Bone wrecks at intersections without red light cameras.
As a wise person once said "When it comes to studies and new laws, always follow the money trail".
Cities want the red light revenue, insurance companies want less claims and I want less injures. I don't heal as fast as I once did.
