Summary

This report, prepared by BioTechnology, Inc. for the National Highway Traffic Safety Administration (NHTSA) and the Federal Highway Administration, addresses the problem of rural and suburban pedestrian accidents. The study aimed to collect and analyze data to identify causative factors and develop potential countermeasures to reduce these incidents. The research was conducted in two phases between July 1973 and March 1976. The methodology involved a stratified random sample of over 1,500 pedestrian accidents from six states: California, Michigan, Missouri, North Carolina, Pennsylvania, and Texas. Data collection relied on interviews with pedestrians, drivers, and witnesses, as well as on-site observations. The researchers gathered detailed information on behavioral sequences, site characteristics, and exposure data to identify both precipitating and predisposing causal factors. The data collection forms covered a wide range of variables, including pedestrian and driver activities, physical conditions, vehicle actions, environmental factors, and specific site features such as roadway geometry and lighting. The analysis focused on grouping behaviorally similar accidents to develop characteristic "accident types." The study identified twenty-three distinct accident types. Notably, the six most frequently encountered types accounted for over 60% of the sample. The report discusses countermeasures intended to apply to each specific accident type. The appendices provide detailed distributions of data items, precipitating factors for pedestrians and drivers for each accident type, and abbreviated accident descriptions. The significance of this study lies in its comprehensive approach to understanding the complex interactions between pedestrians, drivers, and the environment in rural and suburban settings. By categorizing accidents into specific types and linking them to causative factors, the research provides a foundation for targeted safety interventions. The findings support the development of countermeasures that address the specific behaviors and conditions prevalent in the majority of rural and suburban pedestrian accidents, thereby contributing to improved pedestrian safety strategies.
