Research on dementia older drivers and proposal of check system of their characteristics

随着老龄化社会的发展，存在许多老年驾驶员痴呆。他们开着汽车却不知道它们是非常危险的。本研究旨在探讨老年人的驾驶行为及认知特征。研究内容如下。(1)使用测量数据的驾驶性能监控系统：我们制作了一辆特殊的车辆，该车辆具有测量系统，以评估驾驶行为及其性能。我们提出的方法来评估驾驶特性，其中一个人的驾驶特性相比，驾驶学校的教练。(2)认知不良条件下的驾驶行为：研究认知不良条件下的驾驶行为及其特征。利用驾驶模拟器对酒后驾驶行为进行了模拟实验，得到了酒后驾驶行为的特征。(3)老年人特点：我们参加了一个镇的老年人体检。收集了400多个数据，包括痴呆测试。(4)老年人驾驶特征：针对驾校的一辆车，建立了测量系统，对老年人驾驶特征进行了长时间的测量。通过对视频数据的分析，我们提取了老年驾驶员的许多不安全行为，并将其分为几个方面。(5)老年人特征评价工具的建议：因此，我们提出了一种新的老年人特征评价工具。

By growth of aging society, there exist many older drivers who are dementia. They drive cars without knowing they are very dangerous. There are may traffic accidents due to such drivers.In this study, we investigate driving performance of older people as well as cognition characteristics. Research contents are as follows.(1) Monitoring system for driving performance using measurement data : We made a special vehicle which had measuring system to evaluate driving behavior and its performance. We propose method to evaluate driving characteristics in which a person's driving characteristics is compared with that of driving school instructor.(2) Driving behavior under poor cognitive condition : We investigate driving behavior and characteristics under poor cognitive condition. We made experiment using driving simulator for drunken driver behavior and got characteristics of such condition.(3) Characteristics of older people : We took part in medical examination of older people in a town. More than 400 data were collected including dementia test.(4) Driving characteristics of older people : We set measuring system for a car of driving school, and made a long rage measurement of driving characteristics of older people. By examining video data, we extracted many unsafe behaviors of older drivers which were classified into several points.(5) Proposal of tool for evaluation of older people's characteristics : As a consequence, we propose a new tool for evaluation for older people's characteristics.
