This volume presents summaries of each of the three phases of the study. In Phase I, dealing with exposure survey considerations, analyses were performed on classifications of exposure data and procedures for exposure surveys. A pilot survey of driving exposure (vehicle miles of travel) was performed and six variables were determined as best predictors of exposure: driver sex and age, vehicle type and model year, roadway type, and day vs. night. In Phase II, dealing with accident data inaccuracies, data form a survey of drivers was compared with driver's official records to determine under-reporting bias. Results may be used to make corrections in accident data. A technique for correcting accident injury data, based on hospital records, was considered. In Phase III, detailed procedures were determined to implement a national exposure survey in 1972. (Author)
