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. Furthermore, this project will evaluate the efficacy of Virtual Private Network (VPN) to provide a secure wireless environment for communicating with traffic signal controllers. In addition, our approach can also be applied for providing the visually impaired with sidewalk work zone bypass or bus arrival information at bus stops.
