ASTA Accessible Wayfinding

2019–2020 · Accessible sidewalk wayfinding & hazard reporting design

I designed and prototyped ASTA (Accessible and Sustainable Transportation Application), a community-powered service to help people with disabilities find accessible routes through a city. The mobile web app was optimized for hazard-aware sidewalk and transit routing, and reporting hazards and assets. The companion desktop site was designed for public transparency and community-organized reporting events. The work was funded by a HHS SBIR grant.
