About

A screenshot of one of our AccessScore prototype visualizations

Our interactive visualizations of city accessibility are intended to address questions like "is this region accessible?" and "why does this neighborhood have poor accessibility?"

Walkability indices such as walkscore.com model the proximity and density of walkable destinations within a neighborhood. While these metrics have gained widespread use (e.g., incorporated into real-estate tools), they do not integrate accessibility-related features such as sidewalk conditions or curb ramps—thereby excluding a significant portion of the population. In this project, we explore the design, implementation, and evaluation of neighborhood accessibility models and visualizations for people with mobility impairments. We are able to overcome previous data availability challenges by using the Project Sidewalk API, which provides access to 255,000+ labels about the accessibility and location of DC sidewalks.

AccessVis is part of the larger Project Sidewalk initative.
