The Relationship between Fatigue Driving and Injury Severity: An Endogenous Binary-Ordered Probit Model Framework Analysis
Fatigue driving is one of the most risky driving-related behaviors and represented a significant social and economic cost to the community. Several studies have already examined the relationship between fatigue driving and traffic injury severity from different aspects. However, fatigue driving and injury severity in traffic crash may share some common influential factors. Ignoring the impact of these common factors will lead to endogeneity problem and result in biased parameter estimation. Based on 38564 crash records during 2006-2011 in Guangdong province, China, the authors apply an endogenous binary-ordered probit model to examine the relationship between fatigue driving and injury severity considering endogeneity of fatigue driving. The results reveal a substantial and significant negative error correlation between fatigue driving propensity and fatal injury propensity. The influence of fatigue driving on injury severity is significantly underestimated if ignoring the unobserved correlation between them. The authors also separate the sample into commercial vehicle drivers and non-commercial vehicle drivers, and explore the difference of influential factors between these two groups.
