Summary
Night driving fatigue affects performance, especially in older drivers. Electroencephalography (EEG) shows vigilance decline correlates with driving errors in seniors, unlike younger drivers.
Area of Science:
- Neuroscience
- Human Factors
- Transportation Safety
Background:
- Night driving poses risks due to driver fatigue and reduced vigilance.
- Driving performance is known to degrade with fatigue, but age-related differences are not fully understood.
Purpose of the Study:
- To investigate the relationship between driving performance degradation and physiological vigilance during night driving.
- To determine if this relationship is influenced by driver age.
Main Methods:
- Forty-six male drivers (20-70 years) completed a 350-km night driving simulation.
- Driving errors (road incidents, speed deviations) and electroencephalography (EEG) for vigilance were monitored.
Main Results:
- Older drivers showed degraded driving performance correlated with increased theta waves (lower frequency EEG).
- In older drivers, EEG-verified vigilance decline correlated with increased severity of all driving errors.
- Younger and middle-aged drivers did not show the same correlation between vigilance decline and all driving errors.
Conclusions:
- Driving errors as indicators of low arousal vary in relevance based on driver age.
- Age is a critical factor in how vigilance decline manifests in driving errors during night driving.
- EEG-based vigilance monitoring can reveal age-specific patterns of driving impairment.
