With long enough yellows, red light cameras shouldn't be a problem. The places that shorten yellows to raise revenue are criminally stupid. Anyway, this problem will hopefully be moot in ten years or so. If cars aren't driving themselves yet, just send a message to individual cars telling them to stop before the intersection. When the ones allowed to continue have cleared the intersection, give another direction a green light. No need to speed to make a yellow or slam on brakes.
