Summary
This document, published by the National Highway Traffic Safety Administration (NHTSA) in November 2021, serves as a technical reference summarizing effective pedestrian safety countermeasures from the tenth edition of *Countermeasures That Work*. The publication addresses the rising proportion of pedestrians among roadway fatalities, noting that 6,205 pedestrians were killed and approximately 76,000 injured in U.S. traffic crashes in 2019. Pedestrians accounted for 17% of all traffic fatalities. Key risk factors identified include male gender (70% of fatalities), alcohol impairment (31%), urban locations (82%), non-intersection settings (73%), and nighttime conditions (76%). The document highlights that fatality rates per walking trip cannot be calculated due to a lack of systematic exposure data. The paper categorizes evidence-based countermeasures by target population and effectiveness rating. For school-age children, three measures are identified as promising or likely effective: elementary-age child pedestrian training, Safe Routes to School (SRTS) programs, and walking school buses. SRTS is noted as having high usage and short implementation time, combining infrastructure, enforcement, and education. Walking school buses rely on volunteer adults and community involvement, while training programs focus on developmental appropriateness. For all pedestrians, the document evaluates four primary strategies. Pedestrian Safety Zones are rated as the most effective countermeasure (four stars), focusing education, enforcement, and engineering on specific geographic areas with high crash rates. Enforcement strategies, which include highly visible campaigns targeting both drivers and pedestrians, are rated as promising. Reducing and enforcing speed limits is also rated as promising; this measure increases reaction time and reduces injury severity, though its effectiveness depends on public buy-in and infrastructural support. Finally, conspicuity enhancements, such as retroreflective materials and flashing lights, are rated as promising. These are particularly critical given that 75% of fatalities occur in the dark, though usage is limited by user convenience and aesthetic concerns. The significance of this report lies in its guidance for State Highway Safety Offices and professionals in selecting cost-effective interventions. The findings suggest that the most effective programs rely on comprehensive, targeted strategies supported by community engagement. The document emphasizes that countermeasures often overlap and should be deployed jointly; for instance, speeding countermeasures can be combined with infrastructure changes, and bicycle safety curricula can be integrated with pedestrian safety education. By providing specific ratings on effectiveness, cost, usage, and implementation time, the report aims to facilitate the adoption of evidence-based policies to reduce pedestrian fatalities and injuries.
Key finding
Pedestrian Safety Zones are identified as the top-rated countermeasure for effectiveness, while the most effective overall programs rely on comprehensive strategies, targeted implementation, and community-based support.
