The project is part of an effort to provide data to support a engineering position on motor vehicle crashworthiness rulemaking policies. Detailed accident data on pedestrian/light vehicle collisions were collected in order to explore the causes and mechanisms of pedestrian injuries. The data is used to support vehicle design changes intended to reduce the severity of pedestrian injuries. The report details nine aspects of the research enterprise -- study area, team structure, sampling procedure, cooperative arrangements, special data collection techniques, and the procedures for on-scene accident investigation, follow-on accident investigation, accident reconstruction, and accident notification. In addition, major problems experienced and the procedures developed for internal review and quality control are discussed. Recommendations for handling problems related to the sample plan are offered.
