Module D - Slide 30


If the intersection/signal is designed so that WALK interval is given for a crosswalk at a different time than the parallel traffic movement, this raises the priority for having APS at the crosswalk. 4 points are given for that situation. We have termed this situation to be a “non-concurrent WALK interval”. As shown in the illustration, pedestrians receive a walk indication when traffic is moving at another location in the intersection, not when the traffic is moving beside the pedestrian providing the typical cue for the pedestrian who cannot see the WALK. An APS would let the pedestrian know that the WALK signal has been given.
