Study of Traffic Accidents with Micro Mobility: Mini-car

本研究报告了一项关于微型流动性的研究，这被视为支持老年人流动性的一种非常有前途的新方式。在日本，个人移动性与微型汽车的使用有关。在本研究中，使用与微型车有关的交通事故数据和碰撞试验，对微型车事故进行了分析。在日本，每年约有180起与微型车有关的交通事故。安全带使用率仅为44%。安全带能有效地减少受伤的发生率，特别是手臂和腿部的受伤。然而，使用安全带的人往往会遭受更多的上半身伤害，特别是颈部。在碰撞测试中，发现安装在平台上的驾驶室在正面碰撞后有足够的空间保证乘客的安全。但由于中柱变形，安全带肩部锚前移，导致上半身前倾，胸部区域撞到方向盘。

This study reports on a study of micro mobility, which is seen as a highly promising new way of supporting mobility among elderly people. In Japan, personal mobility is associated with the use of mini-cars. In the study reported here, mini-car accidents were analyzed using traffic accident data and crash tests involving mini-cars.In Japan, there are about 180 traffic accidents involving mini-cars every year. The seatbelt usage ratio is just 44%. Seatbelts are effective in reducing the incidence of injuries,especially those to arms and legs. However, seatbelt users tend to suffer more upper-body injuries, especially of the neck.In the crash tests, it was found that the cabin, which was mounted on a platform, had enough space for passenger safety after a frontal crash. However, the upper body was thrown forward and the chest area hit the steering wheel because the shoulder anchor of the seatbelt moved forward due to center-pillar deformation.
