If phase associated pedestrian indications are not acceptable, the "walk scramble" option can provide the ability to leave the signal's pedestrian indications as phase-associated until changed by an adult crossing guard. This type of installation provides for a pushbutton enclosed in a locked box that when pressed, puts all of the vehicle indications to red and all pedestrian indications to Walk for a programmed amount of time (a "walk scramble").
