About the Proven Safety Countermeasures Initiative (PSCi)

In 2008, FHWA began promoting widespread use of certain infrastructure-oriented safety treatments and strategies that can offer significant, measurable impacts as part of any agency’s data-driven, systemic approach to improving safety. FHWA updated the PSCi in 2012, 2017, and 2021, reaching a current total of 28 PSCs. The cumulative list is diverse and broad, and practitioners can implement PSCs to successfully address a variety of crash types and focus areas like speed management, roadway departure, intersection, pedestrian, and bicyclist crashes to save lives and prevent serious injuries. Search Proven Safety Countermeasures.
