Audible Pedestrian Signals (APS) provide aid to the visually impaired at intersections by generating an audible noise that guides the pedestrian through a crosswalk. The effectiveness of these signals, however, is potentially undermined by their placement if planning considerations do not maximize their use. One hundred and twelve blocks of the downtown Salt Lake City area were inventoried in the months of November and December of 2013. Over 500 possible paths were then measured and compared to the shortest possible paths to determine the area's connectivity.
