But then that's not what I did. Sadly for you, I made the comparisons on the same day of week and the same time of day, excluded holidays and sporting events.
The minimum in almost all of them around here is 3 different plans (morning rush hour, evening rush hour, and all other times). Different plans mean different times for each color. Between each plan, there is also a transition built into the computer — and that also changes the color time. In addition, the timing for each light depends on the cars above the sensors in the pavement (or other types of monitors). There is a maximum and minimum time for each color in each direction, depending on the number of cars it senses.
I am aware of all of this, and it tends to make my argument.
There is a maximum and minimum time for each color
This is an admission that yellow light times are manipulated.
It is entirely possible (theoretically) for EVERY SINGLE color in each direction to be a different stop-watch time during the day.
A second admission that EVERY light is manipulated.
computer settings for each and every intersection that details how it is programmed. I assume that you took all of this into account when you stood nearby with your stopwatch.
Yes, it's not that hard.
In a given working day, there are between a dozen and three-dozen changes made to timing. This is based on malfunctions, changes in traffic, new or widened streets nearby changing traffic patterns, new businesses that draw traffic, new housing developments, and new apartments. it is farmed out to private firms, including the one I work for.
Again, manipulation, and you guys are great to be able to widen streets, build new ones, new businesses and apartments inside a DAY.
Actually, the ITE recommends that traffic counts be taken yearly and the traffic light timing be reviewed and adjusted each year. It never gets done
So there's nobody watching you?
We don’t have Red-Light-cameras around here, yet. I fully expect it to be authorized by the legislature next year.
And the contracting supplier getting a percentage, will that be yours?
You are spouting BS.
I can't hold a candle to you.

And you had exactly the same number of cars on top of each sensor, too, I suppose. If not, the times WILL be different.
> “This is an admission that yellow light times are manipulated.”
You use the word manipulated as a weapon over and over. The times are “manipulated” within computer set boundaries to minimize the amount of red time whenever possible. I see that as helping the motorist — and so does the ITE.
> “Yes, it’s not that hard.”
Totally wrong, and you don’t even realize that. I would really, really like to see you set up the times on an intersection some day.
> “Again, manipulation, and you guys are great to be able to widen streets, build new ones, new businesses and apartments inside a DAY.”
Deliberately misrepresenting things again. The traffic timing is usually changed AFTER a traffic count, which is done after the traffic has stabilized after construction is done. The “manipulation” is done to reduce the amount of time spent on red based on the latest data.
> “So there’s nobody watching you?”
The politicians who hire us get reports on what we do every year. If they cannot handle it, maybe they should hire their OWN traffic engineer. They can do that you know. However, places that have done that usually end up with worse traffic timing because the POLITICIANS end up dictating what they want instead of what is best for the City as a whole.
> “And the contracting supplier getting a percentage, will that be yours?”
Wrong. We (and other engineering consulting firms that I am aware of) don’t do Red-Light-cameras. A completely different, self-contained “for profit” firm does that.
