Development of Functional Visual Field of Driving fitness for Elderly.

最近在日本，高级司机的交通事故一直在增加。本研究的目的是开发适合驾驶的筛查工具。然后，我们对75岁及以上的资深司机进行了实地调查。结果，认知功能下降的人中有10%存在。他们不想退还驾照，因为他们的生活变得不方便。接下来，我们开发了测试VFit-EV，它可以筛选年长司机的驾驶健康状况。我们让20位老人乘坐VFit-EV。因此，我们获得了良好的重测信度。接下来，我们比较了VFit-EV和VFit-EV在方向盘后由认证驾驶教练进行评估的结果。结果，我们获得了良好的效度。最后，我们比较了VFit-EV在13名出租车司机的交通事故中的应用结果。然而，VFit-EV之间没有交通事故的关系。

The traffic accident by senior drivers has been increasing more recently in Japan. The purpose of this study was to develop the screening tool of fitness to drive. Then, we performed the factual survey to the senior drivers aged 75 and over. As a result, 10 percent of them to whom the cognitive function is falling existed. They don`t want to returned their driver`s license for their life turned inconvenient. Next, we developed test VFIT-EV which screens an older driver's fitness to drive. We got the 20 elderly to take VFIT-EV. As a result, we acquired the good re-test reliability. Next, we compared the result for which VFIT-EV between behind the wheel assessment by certified driving instructor. As a result, we acquired the good validity. Finally, we compared the result for which VFIT-EV between traffic accidents of 13 taxi drivers. However, there was no relationship of a traffic accident between VFIT-EV.
