Traffic light circuit with 556 timer?

;D Yeah.
It's good that it is being admitted to. You can now get down to brass tacks on how much they receive and how much they waste.

I don't think they meant to admit it, it was more one of those "Whoops, said that out loud" moments that ended up getting quoted in the article.
It would bother me a bit less if they just were forward about it being about revenue, I'm fine with a tax on people who can't follow the rules and running red lights is a particularly annoying not to mention dangerous habit that has been increasing. Shortening amber light intervals is BS though, they have to know that will increase accident rates, they should have generous amber intervals so that people have time to stop safely without slamming on their brakes and getting rear ended by the guy behind them who thought they were going to gun it through the yellow, that is, if the goal was actually improving safety. I'm also not fond of the fact that our red light cameras are normally run by a private out of state company that skims a substantial profit, and they are not normal traffic tickets so they are much harder to contest in court than a ticket from a police officer.

What is a crime is that you got to 10k posts before I got to 1k. :scared:
Ed.Kloonk:
But there's still time..

Wow,
the official was not fired
plus no injunction against the city?
Around my neck of the woods,
at least they have delayed the green,
as they know everyone is racing it to
get through those amber signals.
With all the "AI" going on these days,
you'd think they would use those traffic light cameras
to intelligently delay ( or not ) the green
depending on whether or not the cross traffic
has stopped ( or is not even present ).
I've never heard it discussed,
but the concept of an amber go zone
( if this zone is ahead of you when the light turns amber,
do not even think about gunning it, get on the brakes )
should be integrated into driver's education
as well as marked out with striping across
the roadway and signage to the side, plus
maybe even a sign strung above the roadway.
It does not take a genius (no offense to any traffic engineers)
to figure out how far such indications should be
from the intersection (including a decent safety margin -- there are
online esitmaters that include reaction time and etc...)
(there could also be an earlier {further before the intersection}
indication for wet conditions or whatever is found to increase safety )
I guess no governing body would actually do this
as the lawyers would get their greedy fingers in
there as someone is gonna figure out how to
to create a wreck no matter what.
Well, then there are those traffic circulations
popping up more and more that seem to
be working out pretty well in most cases....
