There are a bunch of those main road always green until the sensor or button happens intersections near me. Pressing the button makes them change about 3-5 minutes later. A vehicle triggering the sensor makes them change usually about 1-2 minutes later.
Yeah. Its pretty hit-or-miss. it seems pretty rare to find spaces that setup the lights to handle interrupts well. Makes no sense to make people wait longer when the crosstraffic sensors doesn’t sense anything and the interrupts haven’t happened within a very short period, yet that seems the norm around where I live. So I’m always pleasantly surprised when I’m in a more pedestrian-friendly area that does do it correctly.
