Abstract PedPal is a prototype mobile (smartphone) app designed to assist pedestrians with disabilities when crossing the street at signalized intersections. PedPal interacts directly with the traffic signal system controlling the intersection to communicate both crossing intent (eliminating the need to seek out and push a pedestrian call button) and personalized crossing constraints (ensuring sufficient time is allocated for the pedestrian to cross). Future versions of PedPal will incorporate the ability to monitor crossing progress and to dynamically extend the crossing time in situations where more time is needed to safely get across, as well as provide enhanced capabilities aimed at improving crossing efficiency and general mobility. In this report, we summarize an initial series of user tests that were conducted with the PedPal mobile app and present the results that were obtained.
