Deploy and Test a Smartphone Based Accessible Traffic Information System for the Visually Impaired

Previous research developed a smartphone-based accessible pedestrian system to support wayfinding and navigation for people with vision impairment at both signalized and un-signalized intersections. A digital map was also created to support the wayfinding app. This system allows a visually impaired pedestrian to receive signal timing and intersection geometry information from a smartphone app for wayfinding assistance. The proposed project will leverage the previous development by installing the system at a number of intersections in downtown Stillwater, where MnDOT operates the signalized intersections. The smartphone-based accessible system will be tested and evaluated on the effectiveness and usefulness of the system in supporting their wayfinding and navigation while travelling through signalized and un-signalized intersections.
