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

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?
