Summary
This study identifies common driver mental workload assessments like EEG and eye tracking. It also shows how driving distractions impact workload, informing future vehicle safety research.
Area of Science:
- Human Factors
- Transportation Safety
- Cognitive Psychology
Background:
- Driver mental workload is crucial for vehicle safety.
- Understanding workload is key to mitigating driving distraction risks.
Purpose of the Study:
- To identify common assessments for evaluating driver mental workload.
- To explore the relationship between mental workload and driving distraction.
Main Methods:
- Systematic literature review of academic articles (Jan 2015 - Apr 2020).
- Utilized PRISMA checklist and flow diagram for study selection.
- Focused on workload measurement methods for drivers.
Main Results:
- Common assessments include Karolinska Sleepiness Scale (KSS), NASA TLX, Electroencephalogram (EEG), Heart Rate (HR), eye tracking, and driving performance.
- Driving distractions demonstrably affect driver mental workload as measured by these assessments.
Conclusions:
- Findings highlight the need for multimodal monitoring in driving assessments.
- Future research should focus on increasing the validity and robustness of driving assessments through integrated methods.
