Safe Speeds SF Campaign Evaluation

This a high-visibility enforcement (HVE) campaign focused on driver speeds to support safer conditions for people walking and biking showcases a good example of the partnership between local law enforcement, public health and transportation agencies in focusing on high visibility traffic enforcement. The evaluation of this project, conducted by San Francisco’s Department of Public Health (SFDPH) and researchers at the University of North Carolina’s Highway Safety Research Center, found that reductions in driver speeds achieved during HVE enforcement began to diminish one week post-enforcement. There was not a lasting effect of the HVE campaign once it ended. This points to the importance of regular, sustained efforts to achieve lower vehicle speeds.
