Sometimes, but not always, when a bus (in the dedicated bus lane) stops at this signal, the driver reaches out a window to push a little button up on a pole.

Is this a beg button for buses?

What does it do?

Why isn't this done with sensor or radio?

What happens if you just walk up and push the button?

Does a light illuminate on a control panel in a central office somewhere? Is there a beep?
