Agreed. I think any equipment/service contract which is based on a
percentage of fines is wrong since revenue then becomes the major
controlling factor.
I was hoping there might be someone on the list who's familiar with real
life traffic engineering within a metro area. Again, it seems like there
should be some sort of guidelines as to how long a yellow should be for
safety (based on speeds, road conditions, etc.). Or is the cynical view
that safety is ignored for revenue purposes what really happens? I have
noted that yellows along some higher speed roadways are much longer than
on some other roads (California).

Mostly agreed. But I think you have to acknowledge that a lot of people
will speed up when they see a yellow in order to try to make it all the
way through an intersection before it turns red (i.e., they presumably
enter the intersection on a yellow). I see it every day. And it's a
dangerous thing to do. I can't see how increasing the yellow's duration
will reduce that problem. I've been told that some officers will
automatically issue a citation if they observe a driver accelerating to
make a yellow light.
Now when you mix that with drivers who will slow down & prepare to stop
when they see a yellow (can you imagine that?), you have a dangerous mix.
Rear-enders happen because of that mix & they can be bad ones. It
apparently gets worse (my assumption) when people learn there's a camera
at a given intersection & make bad decisions to stop when they shouldn't.
