Objective: The cognitive and driving performance of both young adult drivers and elderly drivers during unexpected driving situations were compared and analyzed, using a graphic driving simulator. Background: An unexpected event described as while driving, the lead-vehicle stops unexpectedly the participant vehicle needs to apply last minute braking to avoid accident. The physiological stress and responses involved during unexpected event are studied very little. Aging makes people do less social, physical and psychological activities. Method: The cognitive parameters considered were percentage of relative beta spectrum power, measured from Fz and O2 area using electroencephalogram, and R-R interval measured using an electrocardiogram. The driving performances measured from the driving simulator were: crash rate, inter vehicle distance, reaction time, full braking time and participant vehicle approaching velocity to the unexpected event. There were two groups of participants employed in this study. The younger group 26.3±2.0 years of age and older group were 65.6±5.0 years of age. Nineteen participants were assigned to each group, and these groups included only male drivers. All the participants were experienced two unexpected driving situations, one while driving at 70 km/h and another at 90 km/h. Results: Compared with young drivers, elderly drivers showed longer and greater cognitive stain during unexpected events. Electroencephalogram analysis showed significant difference (p < 0.05) in relative beta spectrum power before and after the unexpected event, and also a significant difference (p < 0.05) between driving situations. Young drivers reacted quicker to the sudden event than elderly drivers. Therefore, the crash rates were higher by the elderly drivers in both driving situations. Conclusion: Elderly drivers showed the different physiological responses under unexpected events and may need different guides for the safer driving.
