Decades of traffic engineering based on a math error

"Because of the presence of the 2 in the denominator, the Formula is not an equation of motion. In physics terminology, a formula that is not an equation of motion means that objects in the real world do not abide by it. Had the formula been Y = tp + v/(a + Gg), then the formula would be an equation of motion. But the Formula says v/2(a +Gg) which means that the yellow light lasts half the time it takes for a driver to stop. "

Wow.

But it's random whether they catch anyone that way or not! This technology can still be improved upon! My red light software would wait until there are one or more cars inside the danger zone before turning the light to yellow, which would then last a barely-perceptible fraction of a second! It would catch one or more cars on every light change! Muahahahahahaha!

Oh yes, did I mention I'm evil?
I'm trying to teach myself how to set things on fire with my mind. Hey... is it hot in here?

that surprises me about as much as that economics thing they were talking about last year based on a flawed spreadsheet that nobody could replicate but they just accepted anyway.

Figures. It certainly explains why I have to blow through so many 'orange' lights. In my mind, the yellow light needs a period of time for driver recognition, then driver response, then vehicle response, plus a margin of safety before the red light activates.
I know it just wouldnt be right to kill all the stupid people that we meet..

But do you think it would be appropriate to just remove all of the warning labels and let nature take its course.

There are two reliable signs of a complete pussy who doesn't believe in himself:

1. People who double check their work
2. People who test things before they deploy them.

Push forward and damn the consequences.

I don't know why anyone is surprised by this.

It's been shown that red light cameras increase traffic accidents at lights.

It's been shown that the lights with cameras have shorter yellow lights than those without.

It's pretty clear that they are there for revenue production, not safety.

Hi ryoder,

This is what happened here where I live, Beaverton, Oregon.

As to shown where, it was numerous articles in the local newspaper.

I cannot offer any thoughts on shorter times for yellow lights, etc; but I do know that here, there was an increase in traffic accidents. Not so much now as people are getting used to them and are more wary.

Yeah, people would slam on the brakes rather than go through the light with the camera, and get rear-ended by the people tailgating them.
