The emergence of shared electric scooter (e-scooter) services has introduced a new mobility option in numerous urban areas worldwide. Safety concerns surrounding e-scooter riding have prompted some cities to impose bans or restrictions on shared e-scooters. This study aims to assess the impact of e-scooter restriction policies, on the spatiotemporal distribution of e-scooter injuries and factors influencing injury severity in Helsinki, Finland, in 2021 and 2022. These restrictions include banning shared e-scooter use from midnight to 5 a.m. on weekends and reducing speeds during certain hours.
This study employed an ordered logit model, heatmap analysis of crash locations, and temporal analysis across different time frames to achieve these objectives.
The findings indicate a 64% reduction in the number of e-scooter injuries after the restrictions. However, the severity of injuries experienced only a slight decrease. Notably, the trend of injury severity appeared smoother in 2022 compared to 2021, with spikes occurring from Friday to Sunday. The spatial distribution of crashes revealed that, in 2021, most crashes were concentrated in the city center, while in 2022, the crash locations were more scattered, partly due to the increased area serviced by e-scooters. The results also underscored the substantial impact of alcohol intoxication, as it significantly increased the probability of more severe injuries. Furthermore, higher age groups and people using e-scooters from 4 p.m. to 9 p.m. are more likely to experience higher injury severity after the restrictions were implemented. These research outcomes offer valuable insights for other cities, providing lessons on how to tailor policies to effectively reduce the number of e-scooter-related injuries.
共享电动滑板车服务的出现为全球众多城市地区带来了一种新的出行选择。围绕电动滑板车骑行的安全问题促使一些城市对共享电动滑板车实施禁令或限制。本研究旨在评估2021年和2022年芬兰赫尔辛基电动滑板车限制政策对电动滑板车受伤的时空分布以及影响受伤严重程度的因素的影响。这些限制包括在周末午夜至凌晨5点禁止使用共享电动滑板车以及在特定时段降低速度。
本研究采用有序逻辑模型、碰撞地点的热图分析以及不同时间框架的时间分析来实现这些目标。
研究结果表明，限制措施实施后，电动滑板车受伤人数减少了64%。然而，受伤严重程度仅略有下降。值得注意的是，与2021年相比，2022年受伤严重程度的趋势显得更为平稳，周五至周日出现峰值。碰撞的空间分布显示，2021年，大多数碰撞集中在市中心，而2022年，碰撞地点更为分散，部分原因是电动滑板车服务的区域增加。结果还强调了酒精中毒的重大影响，因为它显著增加了更严重受伤的可能性。此外，年龄较大的群体以及在下午4点至晚上9点使用电动滑板车的人在限制措施实施后更有可能经历更高的受伤严重程度。这些研究结果为其他城市提供了有价值的见解，为如何制定政策以有效减少与电动滑板车相关的受伤数量提供了经验教训。
