Stockholm is one of the safest cities for pedestrians, cyclists, and drivers. The reason is that if an automobile crash occurs, it’s not treated as just an accident.
Instead of writing it as a one-off and blaming whoever was involved, the city takes the time to investigate design of the street and improve it so that there are no more crashes there.
This approach helped to reduce traffic fatalities by half (from 445 in 2006 to 204 in 2020).
