M, it might. My reference in the post to “poor traffic engineering” certainly includes the possibility of flaws in timing and sequencing at intersections. I encounter a lot of traffic light timing problems at Las Vegas intersections–far more so than in other places I’ve lived. In many cases it’s entire cycles that strike me as too long. But having said that, I don’t know that the solution to red-light running is longer yellows. They generally don’t seem that short to me now. The problem I see is a certain number of folks perceiving a yellow light as a starter’s pistol, speeding up and entering the intersection before it turns red. While longer yellows might restrain the cross traffic, which would be good, in the long run I fear they might encourage even worse behavior on the part of the runners who might think they can take greater risks. And as we know, as its essence Las Vegas is a place with a great tolerance for risk.
