The Car Crashes That Go Undetected


The Vision Zero program many cities use to reduce traffic deaths depends on data to inform where to target safety measures like redesigned streets and speed limits. But, when significant numbers of crashes, particularly involving pedestrians and bicycles, go missing in the data, the interventions miss the problems. Racial disparities in unreported crashes or unresponsive police mean that the problems are compounded in under-served areas. Data improvements in D.C., San Francisco, and other cities aim to fill the gaps so that the benefits of Vision Zero can extend to places where they're needed most.
