LOL, if the state was really interested in safety, they could lengthen the duration of the yellow light, not shorten it, as was done to the lights with cameras in a jurisdiction near me.
They could also lengthen the delay between one direction going red and the other green...but that wouldn't create "revenue."
Of course a big portion of the reason for those cameras are to generate income for the govt. And that does what to mitigate her personal responsibility?
In order to make more money some just make the yellow light variable. The traffic camera people make more money than the city, but they are not placed there for safety, anyone that thinks so is delusional.
The problem with that is that human nature being what it is, those who like to "cut it close" rationalize cutting it closer and closer, because "well, there's going to be a delay before the other light turns green anyway, so I can still make it" or " well, the yellow is going to stay yellow longer, so I can speed up and zip through." Right up until they rely on gaming the system one too many times and hit somebody, usually at a fairly high rate of speed, since they're trying to "beat" an already turned light. Extending the gaps just encourages more people to try their hands at "cutting it close," because most people are lazy and impatient and don't like to wait. I'm not a fan of traffic cameras, but extending the times just encourages more people to run lights, because it gives them a wider margin for error.
