Abstract
The report presents the results of a study of commercial vehicle accident statistics, with the objectives of establishing and evaluating appropriate data base development procedures and statistical analysis techniques, and of deriving inferences about accident causation and the potential of possible countermeasures. Special aspects of the study are the estimation and introduction into the causation analysis of (a) the exposure of commercial vehicles to accidents, and (b) surrogates for accident economic costs.
