Comparative study of the work load between one-man buses and two-man buses
Acta Medica Okayama
|June 1, 1985
Summary
One-man bus drivers experience greater occupational fatigue due to increased workload and stress compared to two-man bus drivers. This study highlights significant physiological and safety differences impacting driver performance and well-being.
Area of Science:
- Occupational Health
- Human Factors Engineering
- Transportation Safety
Background:
- One-man bus operations present potential challenges to driver well-being and safety.
- Previous research indicates varied physiological and psychological responses to different driving configurations.
Purpose of the Study:
- To compare the physiological and safety conditions between one-man and two-man bus operations.
- To investigate the impact of bus operation type on occupational fatigue in drivers.
Main Methods:
- Workload assessment including time studies, subsidiary behavior analysis, auditory tasks, and memory tests.
- Physiological measurements such as Galvanic Skin Response (GSR) and other physiological function tests.
- Self-administered questionnaires on safety perceptions and subjective fatigue complaints.
Main Results:
- One-man bus drivers faced greater visual and postural restrictions.
- Reduced mental capacity, increased mental fatigue, and higher stress levels were noted in one-man bus drivers.
- One-man bus drivers reported more subjective fatigue complaints and experienced a higher incidence of near accidents.
Conclusions:
- One-man bus operation imposes a significantly greater mental and physical workload on drivers.
- The findings suggest a need for interventions to mitigate the adverse effects of one-man bus operations on driver health and safety.
