Data Collection

Students and volunteers are collecting data across the City of Atlanta and beyond developing a working database of sidewalk data.

The team is currently collecting data in the City of Atlanta using Android software developed by Georgia Tech and deployed on a tablet mounted to a standard wheelchair.  Data collection entails running the app while walking the wheelchair along the sidewalk segment of interest.

  • The Sidewalk Sentry Android App is used to collect data
  • The app collects video, accelerometer, gyroscope, and GPS data
  • Researchers take data in city block-length segments
  • Diverse geographic locations, land use, and sidewalk quality are included in the sidewalk segment evaluation database

Community members and high school student volunteers participate in data collection along side graduate and undergraduate students.
