Abstract
Operator fatigue is a critical issue that applies to all modes of commercial transportation. Managing the fatigue of commercial transportation operators requires an understanding of the practical challenges faced by operators in managing alertness. A survey of risk factors was conducted among twenty-five commercial transportation operators to help the broader commercial transportation industry understand the relevance of fatigue problems to their operations. A number of factors associated with operator fatigue were found to be common across the airline, rail, maritime, and trucking operations studied. Findings pertaining to eight factors that were found to have a major influence upon operator fatigue are presented. When these factors are present, they can be addressed through comprehensive fatigue management programs that address the systemic causes of fatigue; as well as through countermeasures that may provide long-term or temporary relief to operators.
