Where the Sidewalk Ends Data Driven Urban Safety

" summary

MOSEY is a Streamlit app that pulls MassDOT crash lat/longs and Walk Score via the Walk Score API, visualizes them with OpenStreetMap, geopandas and folium, and returns crash counts around an entered address over the last 10 years. It uncovers hotspots, underreported incidents from scanned police PDFs, and supports advocacy — joining local groups and pushing a proposed trail; one rotary change drops crashes from 47 to 22 in two years. Code and data live on the repo.
