Abstract:This report details the results of an analysis that compared the Crash Avoidance
Research Data Base (CARDfile) with the National Accident Sampling System (NASS).
CARDfile combines, in one data base, the police accident records for three years
(1983 through 1985) from Indiana, Maryland, Michigan, Pennsylvania, Texas, and
Washington. It comtains in excess of 4.0 million accidents that involved 6.5 million
vehicles. NHTSA's Office of Crash Avoidance (NRD-50) uses CARDfile to evaluate
crash avoidance concepts and to assist in program development.
To make the best use of CARDfile, it is important to understand how well the
accident experience derived from the six CARDfile states compares to other national
data bases.
During the first effort in this evaluation, TSC examined the general characteristics
of the population, the vehicles, the roads, and the fatal accidents in these states and
compared them to the same characteristics for the whole nation. We found that the
six states agreed well with the nation (Salvatore, Mengert, Walter, 1987).
