As a mobility of future, the popularity of personal mobility vehicles (PMs) is rapidly increasing worldwide. However, this boom in the use of PMs has resulted in a substantial number of accidents involving not only PM users but also other road users including pedestrians, bicyclists, and motor vehicle drivers. This study aims to explore the potential risk factors for the occurrence of PM-related accidents and the resulting injury severity using the Traffic Accident Analysis System (TAAS) of South Korea between 2017 and 2019. We found that PM–pedestrian accidents tend to occur on roads with wider sidewalks and bike lanes, possibly because the pedestrian–PM conflict increases in this road condition. There is still ongoing debate on whether it is appropriate for PMs to share the sidewalk with pedestrians. Some countries, including Korea, prohibit the use of PMs on sidewalks; however, in reality, this regulation is not well-observed because using PMs on roadways involves higher crash risk with motor vehicles. This study suggests one potential solution to ensure safety of PM users: expansion of bike lane infrastructure having physically separated bike lanes and sidewalks/motorways in addition to the formation and strict enforcement of appropriate safety rules for PM users.

在哪里骑？调查个人交通事故的潜在危险因素的探索性研究

作为未来的出行工具，个人出行工具（PM）的普及在世界范围内迅速增长。但是，PM的使用激增导致大量事故，不仅涉及PM用户，还涉及其他道路用户，包括行人，骑自行车的人和机动车驾驶员。这项研究旨在使用韩国交通事故分析系统（TAAS）在2017年至2019年之间探索发生PM相关事故的潜在风险因素以及由此造成的伤害严重程度。我们发现，PM行人事故往往发生在人行道与PM的冲突在这种路况下增加，因此人行道和自行车道较宽的道路。关于PM与行人共用人行道是否合适仍存在争议。一些国家，包括韩国，禁止在人行道上使用PM；但是，实际上，这一规定并未得到很好的遵守，因为在道路上使用PM会带来更高的机动车碰撞风险。这项研究提出了一种确保PM用户安全的潜在解决方案：扩展自行车道基础设施，在物理上将自行车道和人行道/机动车道分隔开来，此外还要制定和严格执行PM用户的安全规则。
