Driver aging and its effect on male and female single-vehicle accident injuries: Some additional evidence

Abstract

Introduction This study explores the differences in injury severity between male and female drivers, and across the different age groups, in single-vehicle accidents involving passenger cars. Method Given the occurrence of an accident, separate male and female multinomial logit models of injury severity (with possible outcomes of no injury, injury, and fatality) were estimated for young (ages 16 to 24), middle-aged (ages 25 to 64), and older (ages 65 and older) drivers. Results The estimation results show statistically significant differences in the factors that determine injury-severity levels between male and female drivers and among the different driver age groups. Conclusions We discuss a number of plausible explanations for the observed age/gender differences and provide suggestions for future work on the subject. Impact on Industry A better understanding of age and gender differences can lead to improvements in vehicle and highway design to minimize driver injury severity. This paper provides some new evidence to help unravel this complex problem.
