Interplay between mapping and understanding pedestrian access through an equity lens
summary
A practical method for city‑scale pedestrian mapping maps sidewalks, crossings, curb ramps and on‑sidewalk vs on‑street segments together so routing and network analyses actually work; the project builds a routing app (AccessMap), a curated dataset (OpenSidewalks) and uses the HOT Tasking Manager to break work into tasks, fully mapping three cities (Bellingham, Buron and Seattle). The system produces accessible trip plans and walk‑shed equity analyses that reveal dramatically smaller reach for a manual wheelchair profile.
