Modeling Fatigue-Induced Collision Relative Risk: Implications of Service Hours and Fatigue Management Policies on Transit Bus Operators in Florida


This research explores the association between fatigue-induced crash risk, transit operator hours of service and fatigue management policies in the state of Florida. Data used in this study include incident data archived by transit agencies and bus driver schedules. The results show a decreasing trend of collision risks when drivers start their schedules late morning or afternoon compared with early morning. The effect of time on task shows increasing collision risk as drivers drive long hours without enough off duty periods.
