Do those "walk" buttons at traffic lights really work? Do they make the lights change faster?

Yes, I think they do help the lights change faster.
No.  It is just a powerless pedestrian placebo put there to make people feel good.

You know when you are crossing the street at the traffic lights on foot, and they have those buttons labeled "Push Button for Walk"? Do you believe that pressing that button actually expedites the changing of the lights and the appearance of the "walk" signal? Or do you think the light will change in the same amount of time whether you press that button or not?

    It still all depends on who set the control box.

    The real explanation.
    Those buttons place the pedestrian in a waiting que just like the sensors in the street do at intersections. Many people do not realise that traffic lights are controlled at many intersections by magnetic sensors in the street. You can see the outline of the wiring in a rectangular cutout outline in the street near the crossing.
    These sensors tell the traffic control computer how many cars are lined up and whether there are any there at all. You may notice that getting to an intersection late keeps you from getting a green turn arrow. Some places have the sensor back from the intersection to make it possible for tractor trailers to make a turn. This is indicated by the thick white line being a way back from the intersection, as is the rectangular cut out.

    Now, when you push the button for the crosswalk it acts as if you are a waiting car at the intersection and puts you in line for a light.
    I hope that makes it clear.

    You should also include sha_lyn68's explanation below.

    They are not meant to make the light change faster. The walk buttons temporarily halt turn only green arrows (and in some cases any green light) for the parallel street once the next cycle of signals starts.

    Only if traffic is heavily congested and you are running late for work, then the sumbeatches change the farkin lights.

    They don't make the light change any faster. What they do do is give you the white/green walk symbol to cross and not the red walker symbol. They keep the parallel cross street from changing for a few minutes so cars turning left can't go.

    If pedestrians and drivers obey them, they work. It is just like any other traffic law.

    They're there so people can sit there and keep pressing them 10,000 times thinking its helping, when actually its just wasting their time so it makes it seem like that they werent standing there that long

    I walk quite often and don't think they help. Also the light doesn't flash long enough. It always changes when I get part way across.

    The speed of the light change is inversely proportional to the number of times you press the button.

    Ok .. here's my experience ..

    IT ALL Depends on whether it is maintained (or not). I've gone to lights where you can press until you drop and it will NEVER give you the Walk Sign ..

    I've gone to lights where you can press and then within a reasonable time it will say WALK

    I've gone to lights where you can press and then it will say WALK .. but you really have to HUSTLE Because if you are not a Marathon Runner -- you'll be STUCK in the middle!

    Which do you want to take?

    No, they just have the all the lights stop at the next interval that would be appropriate.

    The one thing I have noticed is that when the orange hand starts flashing the light is about to change so either slow down or pedal to the metal for those in a hurry.

    There are intersections on some expressways where the cross-traffic lights never turn green unless a vehicle stops on the inductive sensing loop or a pedestrian pushes the walk button. Those buttons most definitely work. One only needs to push them once, though. Pushing them additional times doesn't speed up the cycle.

    I have no clue since we live in community where that is not ever an issue and crossing the street is no big deal. We stop traffic. With a friendly wave.

    This is what I suspect, anyway. You would think the timing of the lights has to be quite careful and exact in order to not allow the go-ahead signal to occur in more than one direction at once.
