Despite comprehensive civil rights legislation for Americans with disabilities, many city streets, sidewalks, and businesses in the US remain inaccessible. The problem is not just that sidewalk accessibility fundamentally affects where and how people move about in cities but also that there are few, if any, ways to easily determine accessible areas of a city.

You can help change this! Use our interactive tool to virtually walk through city streets and mark accessibility attributes such as missing curb ramps, blocked or overly narrow sidewalks, and broken pavement. Our focus is currently on Washington DC—so, if you've never been there, enjoy walking through the U.S. Capitol—but we plan on launching in other cities soon (including outside the US). Your data will be used to create new types of map-based accessibility tools, such as AccessScore, an interactive map of a city's accessibility, and RouteAssist, personalized routing algorithms based on a user's reported mobility level.

We also have some secret sauce: to scale our approach, your labels are also being used to train machine learning algorithms to automatically find future accessibility problems.
