Summary
This study, conducted by Dunlap and Associates East for the National Highway Traffic Safety Administration (NHTSA), evaluated the effectiveness of public information and education (PI&E) messages designed to reduce specific types of pedestrian accidents. Building on previous research identifying distinct accident types based on behavioral errors, the project aimed to test whether mass media campaigns could modify unsafe behaviors in "real world" settings. The study focused on two primary accident categories: "Dart-Out" accidents, predominantly involving children, and "Vehicle Turn-Merge" (VTM) and "Multiple Threat" (MT) accidents, which primarily involved adults. The experimental design involved developing targeted media messages and distributing them in selected test cities. For children, an animated character named "Willy Whistle" was used in TV spots, radio ads, and classroom films to teach safe crossing behaviors, such as stopping at curbs and looking left-right-left. These materials were distributed in Los Angeles, Columbus, and Milwaukee between 1976 and 1977. For adults, TV and radio spots addressed VTM and MT scenarios, instructing drivers to check for pedestrians before turning and pedestrians to verify they have been seen before crossing. These adult messages were tested in Los Angeles and San Diego from 1976 to 1977. The study utilized a seven-step model of public education, measuring exposure, recall, knowledge, behavior, and accident rates before and after the intervention. The results for the child-focused "Willy Whistle" campaign were highly positive. Exposure was high, with significant airtime during prime hours for children. Surveys showed dramatic increases in children's knowledge of safe crossing behaviors, particularly regarding novel concepts like reinitiation of the look sequence. Behavioral observations indicated statistically significant improvements in children's search behaviors. Most importantly, time-series analysis of police reports revealed a significant reduction in Dart-Out accidents involving children aged 14 and under, with an average decline of over 20% across the three cities. The reduction was most pronounced among children aged four to six, suggesting the TV component was particularly effective for this demographic. The campaign was estimated to have prevented nearly 300 crashes, saving society approximately $3 million. In contrast, the adult messages yielded mixed results. Exposure for adult materials was significantly lower than for child materials due to competition for public service airtime. While Spanish-speaking residents in Los Angeles showed high recall and knowledge gains, English-speaking audiences showed minimal improvement. Behavioral observations indicated that pedestrians improved their search behaviors in VTM and MT situations, but driver behavior data were equivocal due to measurement difficulties. Time-series analysis of accident data showed no significant overall reduction in VTM or MT accidents in the general population. However, a subgroup analysis revealed that VTM accidents involving Spanish-speaking pedestrians or drivers in Los Angeles declined by 18% (approximately 24 crashes per year). The study concluded that PI&E is a viable countermeasure for modifying simple behaviors, but its effectiveness is heavily dependent on achieving adequate exposure, which remains a challenge for adult audiences.
Key finding
VTM accidents involving Spanish-speaking pedestrians or drivers in Los Angeles declined by 18 percent, while general adult pedestrian knowledge and correct behaviors improved despite lower message exposure.
