Abstract

Abstract In recent years, a rush of privately-owned shared micromobility services has descended on many American cities. The increased availability in these emergent mobility options, which include dockless bikeshare and electric scooter systems, offers urban residents, workers, and visitors a convenient travel alternative to more established modes. However, with limited regulation and dedicated infrastructure, the rapid introduction of new micromobility services has come with rising safety concerns. This study provides new evidence on the spatial associations between e-scooter trip generation and vulnerable road user crash counts by investigating eight months of shared mobility data collected during a 2019 pilot program in Brookline, Massachusetts. The findings from traditional and spatial negative binomial models with a set of network and environmental predictors are presented and demonstrate a connection between shared e-scooter and long-term vulnerable user crash activity. Our results illustrate the need for policies that promote shared mobility services through safer infrastructure provisions.

共享电动滑板车出行产生与弱势道路使用者碰撞频率的空间交互作用
近年来,私人拥有的共享微出行服务在美国许多城市兴起。包括无桩共享单车和电动滑板车系统在内的这些新兴出行选择的可用性越来越高,为城市居民、工人和游客提供了一种更便捷的出行方式,而不是更成熟的出行方式。然而,由于监管和专用基础设施的限制,新的微型交通服务的迅速引入带来了越来越多的安全问题。这项研究通过调查2019年在马萨诸塞州布鲁克莱恩的一个试点项目中收集的8个月的共享出行数据,为电动滑板车出行次数与弱势道路使用者碰撞次数之间的空间关联提供了新的证据。本文提出了一组网络和环境预测因子的传统和空间负二项模型的结果,并证明了共享电动滑板车与长期弱势用户碰撞活动之间的联系。我们的研究结果表明,需要制定政策,通过提供更安全的基础设施来促进共享移动服务。
