In the suburbs in southern california, I'm used to one of three things happening:
a) I walk up, the light is red in my direction; I push the button, and the other direction turns yellow within 10 seconds (often immediately), and shortly I get a walk sign
b) I walk up, the light is green in my direction, I push the button, and get a walk sign immediately
c) I walk up, the light is green in my direction, I push the button, and don't get a walk sign -- but soon the light turns yellow, and the other direction gets to go, then i get a walk sign.
It's not too far off in the south bay (SF bay area).
It's different in the middle of a city like Seattle, where there's always a lot of traffic, so the lights are changing frequently anyway, a lot of the lights just have the pedestrian cycle enabled almost always; and they often won't add the walk sign in the middle of a cycle, when it's already decided to change the cycle in less time than is needed for a pedestrian to cross.
