Abstract

Recent studies do not agree on the possible relationships between medical conditions and traffic safety; most of them do not control for exposure factors. In this study, we estimate the effect of different medical conditions (namely diabetes, high blood pressure, coronary disease, and visual impairment) on the distribution of accidents of truck drivers. Our data and our model permit the simultaneous control for age, medical conditions and other characteristics of the truck drivers; exposure factors measured by hours, kilometers, and qualitative factors; and of the circumstances surrounding accidents described in police reports. The results show that truck drivers not in class 1 (79% are class 3) with diabetes have more accidents than the drivers in good health. No other medical condition studied has a significant effect on individual accident rates. Many risk exposure variables are significant. We have also estimated the parameters of the severity distribution. Our data limited the regression analysis of the severity in terms of the number of victims injured or killed. The results indicate that drivers with a visual impairment (binocular vision impairment) have more serious accidents than those in good health. Our cost estimations show that the expected average cost of drivers with diabetes is twice as high as the expected average cost of drivers in good health. The cost differences are less significant for the drivers with a visual impairment. The conclusion summarizes the main results.
