Crowdsourcing of accessibility attributes on sidewalk-based geodatabase

Abstract

Although the issue of limited mobility affects a large portion of the population, current navigation systems working with roadway-based geodatabases are designed primarily for cars and therefore cannot efficiently help. Usage of the professionally created sidewalk-based geodatabase is a solution. However, the professional geographical “on-site reconnaissance” is labor demanding. In this poster, we report on results of preliminary research focused on a design of the gamified collection of accessibility attributes by non-expert crowd, which will reduce the data collection cost. Preliminary results suggest the feasibility of the approach supported by a proper guidance of non-experts and creativity of achieving precise measurements.
