Almost all lights here in Christchurch have buttons to request that the lights change, except for a few like https://www.google.com/maps?ll=-43.553027,172.663193&spn... where the button does nothing, and you have to stand on the yellow pad until the lights change, or have a metal bike.
Not everyone understands that you need to keep standing on the pad, or that the bike crossing doesn’t last long enough to walk all the way across.
Just something curious while "walking around" ... https://www.google.com/maps?ll=41.869635,-87.648258&spn=...

It turns red immediately when you press the button. When I was in college, I would entertain myself between classes by going over, pressing the button just as the upstream light turned green and cars began accelerating, and then not crossing the street.
This, incidentally, is probably why most lights don't change immediately.
