Right of way when two pedestrians approach from perpendicular directions to cross the intersection.

This usually occurs on a busy intersection and is fairly obvious. Chances are pedestrians are walking towards a crosswalk from perpendicular directions (See diagram: Pedestrian 1 moves towards west and Pedestrian 2 towards north). When there is a chance for collision the person who has the "walk" signal (1) should be given the right of way since they have the opportunity to cross since the person who has the "stop" signal (2) has to decelerate to a stop. And by right of way I mean that Pedestrian 2 should let Pedestrian 1 who has the signal to cross go past first. If one is a super aware pedestrian they would pay attention to see if the signal is counting down thereby preparing oneself for possible pedestrians who are accelerating to beat the clock.
