Summary
This 1982 NHTSA technical report evaluates the effectiveness and efficiency of pedestrian safety programs, motivated by the high prevalence of pedestrian fatalities, which constituted 16 percent of total highway-related deaths. Pedestrians represent the largest non-occupant fatality category, with 85 percent of accidents and 60 percent of deaths occurring on urban streets. The report identifies alcohol involvement in one-third of adult urban accidents and poor visibility as significant causal factors. To address these issues, NHTSA and the Federal Highway Administration (FHWA) developed countermeasures targeting specific "accident types" derived from a behavioral "Safety Sequence" analysis. Seven major accident types, such as "dart-out" and "intersection dash," account for 57 percent of urban pedestrian accidents. The study reviews evidence from over 600 entries in Docket 81-12, focusing on eight projects with specific effectiveness data and five with promising results. Methods included field tests of educational programs, enforcement initiatives, traffic engineering modifications, and regulatory ordinances. Specific countermeasures were matched to accident types; for example, safe street-crossing training and safety messages targeted child "dart-out" accidents, while model ordinances addressed hazards associated with ice cream trucks and bus stops. Traffic engineering solutions, such as converting streets to one-way systems and relocating bus stops to far-side intersections, aimed to reduce vehicle-pedestrian conflicts and screening effects. Findings indicate that targeted countermeasures significantly reduce accidents. Safe street-crossing training in Ohio resulted in a 43 percent reduction in dart-out accidents, while child safety messages in Los Angeles, Milwaukee, and Columbus yielded a 20 percent decrease. The Model Ice Cream Truck Ordinance reduced accidents by 77 percent in Detroit and nearly eliminated them in Indianapolis over five years. Relocating bus stops reduced related accidents by up to two-thirds in Arizona, Colorado, and Connecticut. Converting streets to one-way systems reduced pedestrian accidents by 29 to 62 percent in cities including Sacramento, Hollywood, and Manhattan. Enforcement of walking while intoxicated laws in Miami-Dade County reduced accidents by 14 percent. Additionally, fixed illumination improved intersection safety, and comprehensive community-wide projects demonstrated estimated savings of 19 accidents across four cities. The report concludes that a variety of cost-effective solutions exist for specific pedestrian accident types, validating the approach of matching countermeasures to identified behavioral and environmental errors. It highlights the importance of systematic program implementation, supported by NHTSA and FHWA guides and manuals, to enhance efficiency and reduce costs. The findings underscore that while past efforts were often scattered, targeted interventions addressing specific accident mechanisms—such as improving visibility, enforcing regulations, and modifying infrastructure—can effectively change unsafe behaviors and reduce accident rates.
Key finding
Specific countermeasures including safe street-crossing training, model ordinances for ice cream trucks and bus stops, and one-way street conversions significantly reduced pedestrian accident rates in tested jurisdictions.
