For this prioritization, skewed crosswalk is defined differently than a skewed intersections, as it's traditionally defined by traffic engineers, where roads don't meet at 90 degrees (picture on the right). For the APS Prioritization Tool, the crosswalks at that intersection are not necessarily considered skewed.

For the points assigned in this Prioritization Tool, the definition of skew has to do with the issue of whether the pedestrian will end up in the road if they maintain the same approach vector from the sidewalk. In the illustration on the left, a pedestrian who maintains the same line as the approaching sidewalk will end up in the traffic lanes on the far side, thus the crosswalk is skewed. In the illustration on the right, a pedestrian who maintains the same line as the approaching sidewalk will end up on the curb and is traveling roughly parallel to traffic movement, thus the crosswalk is not skewed, even though it is slanted.
