Characterizing Sidewalk Accessibility at Scale

Poorly maintained sidewalks pose considerable accessibility challenges for people with mobility impairments. Despite comprehensive civil rights legislation for Americans with disabilities, many city streets and sidewalks in the U.S. remain inaccessible. The problem is not just that sidewalk accessibility fundamentally affects where and how people travel in cities, but also that there are few, if any, mechanisms to determine accessible areas of a city a priori.

To address this problem, we introduce new scalable methods for collecting data about street-level accessibility using a combination of crowdsourcing, automated methods, and Google Street View as well as proof-of-concept map-based accessibility applications that leverage this data.
