Predicting Fatigue of Haul Truck Operators Using Reaction Time

Key Points

• Fatigue significantly reduces reaction time in haul truck operators, affecting performance.
• A decrease in reaction time measures correlated with increased fatigue levels, notably within a critical range.
• Analysis focused on reaction time as a performance metric to assess fatigue impacts during operations on-site.
• The findings underscore the need for fatigue management strategies to promote operator safety in transport environments.
