Sample interview questions: Can you provide an example of a time when you used human factors principles to enhance the safety of a railway transportation system?
Sample answer:
In a railway transportation system, I led a project to enhance the safety of signaling systems by applying human factors principles.
• Identified the Issue: We observed a high incidence of signal-related incidents due to misinterpretations and errors made by train operators.
• Conducted Human Factors Analysis: We conducted a comprehensive analysis of the underlying human factors contributing to these incidents. This included evaluating the cognitive workload, attentional demands, and usability of the signaling system.
• Proposed Design Changes: Based on our analysis, we proposed several design modifications to improve the user-friendliness and effectiveness of the signaling system. These included simplifying the visual display, enhancing the clarity of signal indications, and incorporating auditory alerts for critical signals.
• Implemented the Changes: The proposed design changes were implemented in a pilot project. We conducted extensive user testing and evaluation to ensure the effectiveness of the modifications.
• Monitored and Evaluated: Post-implementation, we monitored the performance of the signaling system closely. The results showed a significant reduct… Read full answer
