Development of pathNav: A Pedestrian Navigation Tool that Utilizes Smart Data for Improved Accessibility and Walkability

The 2.2 million wheelchair users in the U.S. and 70 million around the world face significant challenges to participate fully in their communities, and people with visual impairments limit their travel to familiar places. Furthermore, one in three older adults fall each year, the majority of which occur outdoors, costing $34 million in direct medical costs. The condition of sidewalks and pathways affect all pedestrians, but people with disabilities, older adults, and injured veterans are especially affected by them. The goal of this project is to develop pathNav, a pedestrian navigation web app that utilizes a connected network of sidewalk and pathway data. The research team will implement the published route accessibility index (RAI) that considers the quality of the pathway as determined by data collected through the PathMeT device and/or reported through the free pathVu mobile app. A web interface will be built allowing pedestrians to search for the most accessible routes to their destination based on their profile (e.g. wheelchair user, individual with low-vision or blindness). Upon completion of pathNav and the web interface, the team will conduct human subject testing to investigate usability and commercial viability. The team hypothesizes that pathNav will: 1) Increase safety and reduce trip and fall injuries 2) Reduce social isolation of people with disabilities and older adults 3) Increase public transit ridership 4) Reduce trip/fall personal injury cases of pedestrians 5) Be accepted by the user group, suggesting it is commercially viable.
