Increased Perception of Strain and Related Cognitive Functions in Drivers with Aging

Abstract

With age, physical and cognitive functions generally tend to decline. However, with appropriate measures, it is possible for older train drivers to continue their duties safely and confidently. The first step in this study was to obtain fundamental data to investigate measures needed to enable older drivers to continue driving. Based on a survey result, we identified tasks for which perceived strain increases with age. Furthermore, it was revealed that the increase in perceived strain of these tasks is associated with age-related declines in attention, vison, decision making and reaction time.
