Add additional geographic data to the map.

Bicycle and Pedestrian Collision Data

This map is the observed pedestrian and bicycle collisions in San Francisco thanks to the Statewide Integrated Traffic Records System (SWITRS) database that included their latitude and longitude. The data was queried through the UC Berkeley SafeTREC Transportation Injury Mapping System (TIMS), which provides summaries, other visualizations, and an easy way to access SWITRS data.
  • Collision locations are snapped to the nearest intersection using the latitudes and longitudes given from SWITRS to the latitude and longitudes of the intersections in San Francisco.
  • Data is complete for years 2006-2021.
  • Data for 2022 is provisional and subject to change.
