Intervention Fact Sheets - Table of Contents

Our main source for identifying interventions was the Countermeasures That Work report (UNC Highway Safety Research Center, 2011). At the time this research began, the 2011 version was the most recent available (an update was published in 2013 [Goodwin, Kirley, et al., 2013]). Because the information was useful, instead of writing entirely new fact sheets, we simply updated them based on the new research findings. For all of the fact sheets, unless otherwise noted, quoted material is from UNC Highway Safety Research Center, 2011. The references include both.

Note: The most recent version of NHTSA’s Countermeasures That Work: A Highway Safety Countermeasure Guide for State Highway Safety Offices is 2015
