FHWA’s Proven Safety Countermeasures initiative (PSCi) is a collection of countermeasures and strategies effective in reducing roadway fatalities and serious injuries on our Nation’s highways. Transportation agencies are strongly encouraged to consider widespread implementation of PSCs to accelerate the achievement of local, State, and National safety goals.

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.
