As much as you may believe, because you encounter them so rarely, Chicago indeed has several types of “beg buttons”. This is a mechanism wherein a person walking along a street must apply to cross another street. You are begging for permission. They are not popular, many are not even hooked up anymore, and they don’t call the pedestrian signal any sooner (their purpose is to make the green traffic signal long enough for a person to cross).
Jan Gehl et. al. succinctly demonstrate in Cities for People the opposing methods of telling a person when they can cross the street (meaning cross traffic has been halted).

The 2013 Chicago Complete Streets Design Guidelines and 2012 Pedestrian Plan reorients the city to prefer facilitating and encouraging transportation by foot over all other modes of travel. But it doesn’t address the beg button directly. It considers many other realities in Chicago that go against the new transportation paradigm that puts the pedestrian first. For example, it calls for the systematic removal of all slip lanes – none of which I’ve heard or seen removed in the year since CDOT created the guidelines.
