Disclosed herein are techniques and systems to guide a visually impaired user through an urban area, such as, across a crosswalk. A mobile device may receive messages broadcast by wireless beacons deployed in an area and determine a path, for example, across a crosswalk, based on the messages. The mobile device can then provide feedback to guide a visually impaired user across the crosswalk.
