Sustainability, Scalability, and Resiliency of the Town of Innisfil Mobility-on-Demand Experiment: Preliminary Results, Analyses, and Lessons Learned Innisfil镇按需移动实验的可持续性、可扩展性和弹性:初步结果、分析和经验教训

In 2017, the town of Innisfil, Ontario, launched Innisfil Transit in partnership with Uber, a transportation network company, to provide a subsidized on-demand public mobility service as an alternative to investing in a new fixed-route bus service. The performance of Innisfil Transit is documented in a 2021 Ryerson University report by Sweet, Mitra, and Benaroya, which shows greater cost effectiveness of the mobility provided over the proposed bus alternative. This paper expands on those findings by assessing Innisfil Transit with respect to sustainability, scalability, and resiliency. First, we quantify the energy and emissions of this program relative to traditional transit and driving alone across varying powertrains. We then characterize a conservative first-order estimate of the percentage of US communities that fall within a similar spatial-demographic tier as Innisfil. Replicability also hinges on service cost and performance in comparison to average values for low-density transit in the US. Lastly, most transit agencies experienced a significant drop in demand (as much as 90%) with slowly rebounding ridership since the onset of the COVID-19 pandemic. The resiliency of the Innisfil program to the pressures induced by the pandemic is examined in comparison to other transit operations. The lessons learned across these three dimensions complement prior work to better understand the efficiency and sustainability of on-demand public mobility service for low-density communities like Innisfil. © ASCE.

2017年,安大略省Innisfil镇与交通网络公司优步(Uber)合作,推出了Innisfil Transit,提供按需公共交通服务补贴,作为投资新的固定路线公交服务的替代方案。2021年,Sweet、Mitra和Benaroya在瑞尔森大学的一份报告中记录了Innisfil Transit的表现,该报告显示,与拟议的公交替代方案相比,Innisfil Transit的成本效益更高。本文通过评估Innisfil Transit的可持续性、可扩展性和弹性来扩展这些发现。首先,我们量化了与传统交通和不同动力系统的单独驾驶相比,该计划的能源和排放。然后,我们对与Innisfil处于相似空间人口层的美国社区百分比进行了保守的一阶估计。与美国低密度交通的平均值相比,可复制性还取决于服务成本和性能。最后,自2019冠状病毒病大流行爆发以来,大多数运输机构的需求大幅下降(降幅高达90%),客流量缓慢反弹。与其他过境业务相比,审查了Innisfil方案对大流行病造成的压力的弹性。从这三个方面吸取的经验教训补充了之前的工作,以更好地了解Innisfil等低密度社区按需公共交通服务的效率和可持续性。©第3期。版权所有。
