The Covariance Between the Number of Accidents and the Number of Victims in Multivariate Analysis of Accident Related Outcomes

This study investigated some statistical issues involved in the simultaneous analysis of accident related outcomes of the highway traffic process. The main focus of the study was on the estimation of the variance-covariance structure of such outcomes. Correction for covariance is needed in order to enhance the statistical reliability of techniques applied to the simultaneous analysis of accident related outcomes. It turns out to be possible to derive relatively simple expressions for the variances and covariances of accidents and victim counts.
