San Francisco has put its most dangerous streets on blast. Today, the city rolled out an updated High Injury Network map that pinpoints the relatively small set of corridors where its most severe crashes keep happening. The new dataset identifies streets that have become safer after upgrades, highlights new trouble spots, and is expected to drive faster redesigns and more focused enforcement in the months ahead.
What the new map shows
Mayor Daniel Lurie announced the 2024 High Injury Network, which uses hospital records, police crash reports, and death records to identify where severe and fatal collisions are clustering, as reported by The San Francisco Standard. The interactive map and its underlying dataset are live on the city's open data portal at DataSF, where officials say the information will help them decide how to spend limited safety dollars.
How enforcement and cameras changed behavior
The city has been pairing quick street fixes with enforcement tools, including an automated speed camera pilot set up where high speeds are most dangerous. An SFMTA evaluation found that speeding dropped by about 72% on average at 15 sampled camera locations after the cameras went in, according to SFMTA.
Proof it can work, and where danger shifted
City officials are already pointing to corridors where recent design changes appear to have cut crashes. Seventh Street between Harrison and Townsend saw injury crashes fall 69% between 2016 and 2024. California Street between 18th Avenue and Arguello Boulevard recorded a 64% drop in total crashes after upgrades, and Townsend Street between Third and Eighth saw a 52% drop in total crashes over the same period.
At the same time, the updated High Injury Network flags newly risky segments, including Fulton Street between Fourth and Seventh avenues, the Embarcadero between Howard Street and Pier 40, and Point Lobos Avenue between 46th Avenue and the Great Highway. That last stretch is called out because an unprotected bike lane forces cyclists to merge into traffic, as reported by The San Francisco Standard.
What is coming next
Transportation officials say they will lean on the High Injury Network to sequence faster “quick-build” projects such as painted curb extensions, protected bike lanes, and other lower-cost changes, while also aligning transit and enforcement resources with the corridors that generate the most harm, per SFMTA. City leaders argue that those near-term moves, paired with continued monitoring, are the most direct path to reducing severe and fatal crashes on the streets flagged by the map.
Residents and riders can dig into the interactive High Injury Network and the underlying crash data on the city’s portal and watch for quick-build projects to roll out along the highlighted corridors. For the full map and datasets, visit DataSF.
