New Transportation Systems for Elderly People

需要对年轻人和老年人都有利的新交通系统。在过去1998-2000年的项目中，我们提出了微型车辆作为解决方案之一。由于本研究的目标是实现这样一种车辆，因此我们将重点放在了实现这一目标的障碍，即操纵臂的改进和交通中的安全性。我们的研究明确了车辆的实现要点，建立了新型交通系统的基础技术。首先，搭建移动基座驾驶模拟器，采集老年驾驶员的驾驶特征，并在常见工况和综合工况下进行评价。我们提出了基于这些数据驱动操纵装置。评价结果证明了人工集成操纵车辆的优越性。其次，以微型电子汽车为例，对该机械手在驾驶模拟器实验中的有效性进行了评价。仿真结果表明了转向传动比的合理设置和手控机械手的有效性。最后，我们从茨城县Juo镇的人们中选择了年轻人和老年人。我们让他们使用微型电动车大约三个月，并填写调查问卷。结果显示了车辆的有用性，并提出了与实现这种车辆有关的问题。

New transportation systems which are of benefit to both younger and older people are needed. We had proposed a micro vehicle as one of the solutions in the past project conducted through 1998-2000. Because the goal of this study is to realize such a vehicle, we focused on the improvement of manipulators and safety in the traffic, which are obstacles to the realization.Our study clarified the points for the accomplishment of the vehicle and established the basic technology for the new transportation systems.First, a moving-base driving simulator has built to collect driving characteristics of older drivers and to conduct evaluation under the common situations and the integrated conditions. We proposed driving manipulating devices based on these data. Evaluation results proved the advantage of hand-integrated manipulation of the vehicle.Secondly, we evaluated the manipulators, which were effective in the driving simulator experiments, utilizing a micro electronic vehicle. The results showed the suitable settings of steering gear-ratio and the effectiveness of hand-integrated manipulators.And finally, we selected both younger and older subjects from the people in Juo town, Ibaraki prefecture. We asked them to use micro electric vehicle for about three months and to fill in questionnaires. The results showed the usefulness of the vehicle and made the point at issue related to the realization of such a vehicle clear.
