Module D - Slide 22


When there is exclusive pedestrian phasing (scramble phasing), all vehicles have a red light during pedestrian walk interval, even though right-turn-on-red may be permitted, and all crosswalks have the walk interval at the same time. Without APS and with the absence of parallel traffic movements, a blind pedestrian will not be able to determine with certainty when the WALK begins and will have no cars moving through the intersection parallel to the crosswalk to use to maintain alignment while crossing.
