Trends in Elderly Drivers Population and Related Accidents in Japan

Yoko Kato･Yasuhiro Matsui･Michiaki Sekine (NALTEC)

Japan is experiencing population aging. Meanwhile, due to increasing automobile dependence and generational changes in driving experience, the proportion of elderly drivers may be increasing at a faster pace. This presentation quantitatively shows the increase in elderly drivers and discusses annual trends in accidents frequently associated with elderly drivers, such as pedal misapplication accidents.

A User Survey of Personal Mobility Devices Was Conducted in a Demonstration Project for Supporting Mobility Among Community-Dwelling Older Adults. The Relationship Between Physical/Cognitive Functions and UX Evaluations of Two Mobility Models Was Analyzed. The Results Suggested the Importance of Selecting and Adjusting Mobility Devices According to User Characteristics.

An intervention study using VR training was conducted with older drivers to examine its effects on safety confirmation behavior in actual vehicle driving. Drivers with safety-oriented characteristics showed a positive correlation between training performance and on-road confirmation behavior, suggesting that driver characteristics influence the transfer of training effects.

Elucidation of Accident Risk Structure in Older Drivers Based on an Integrated Analysis of Driving Aptitude Tests and Surveys on Lifestyle, Health, and Driving Awareness
-Study on Driver Characteristics for Delaying Driving Cessation (50)-

Shunji Taniguchi･Rin Ito･Hirofumi Aoki (Nagoya University)

This study integrates survey data on lifestyle, health, driving behavior, and safety awareness with results from driving aptitude tests to conduct a multifaceted analysis of accident risk structures. The findings confirm pathways whereby health decline increases accident risk through impaired cognitive function, and reveal discrepancies between self-assessed and actual driving abilities. Furthermore, the relationship with the perceived necessity of ADAS is clarified, and directions for effective safety interventions are proposed.
