About the Project

Crash Data Explorer is an analysis and engagement tool for urban pedestrian and bike safety. It is an open source javascript application leveraging Leaflet, Chart.js, CitySDK, OpenStreetMap, Google Street View, and GeoJSON.


This site hosts explorers built on state DOT data, allowing analyses and comparisons between cities based on the full spectrum of crashes, not just fatal crashes. More states and cities will be added as they adopt open data frameworks.


For custom installs and applications, consulting inquiries, or to help get your city and state added to this site, please contact here.
