Summary
Time-critical automation requests increase driver demands, impacting driving performance and posture. Designing automated systems requires considering driver capabilities for safer transitions of control.
Area of Science:
- Human Factors
- Ergonomics
- Automated Driving Systems
Background:
- Automated driving systems are increasingly used in occupational settings.
- Time-critical intervention requests pose challenges for drivers during control transitions.
Purpose of the Study:
- To investigate the impact of time-critical automation intervention requests on driver visual-motor demands.
- To analyze changes in driving performance and driver posture during transitions of control.
Main Methods:
- Measurement of driving performance metrics.
- Assessment of driver posture, including limb engagement and trunk positioning.
- Analysis of maneuver urgency and takeover timing.
Main Results:
- Time-critical intervention requests significantly increase drivers' visual-motor demands.
- Measurable changes in driving performance and posture were observed during control transitions.
- Elevated biomechanical and coordination demands are placed on drivers in work-based automated driving.
Conclusions:
- Automated transportation system design must align request timing with operator capabilities.
- Occupational automated driving requires adequate preparation time for visual-motor coordination.
- System designers and operators should integrate interface timing and alerts to support safe driving performance.
