摘要

几项研究强调了冠状病毒(新冠肺炎)封锁如何永久性地改变了人们的出行方式,但对主要大都市地区以外的影响关注较少,因为这些地区的替代交通方式更加有限或稀缺。本案例研究利用俄勒冈州莱恩县的微观数据,重点研究新冠肺炎封锁对公共交通和共享单车的长期影响。莱恩县(Lane County)反映了美国近3000个由农村和城市景观混合而成的小县城。调查结果显示,在使用量大幅减少后,这两种交通方式都开始恢复,尽管在封锁18个月后,与公共交通相比,共享单车的弹性似乎较弱。此外,研究结果显示,公交车乘客量和共享单车出行的变化因社会人口特征而异,尽管共享单车出行对变化更敏感。例如,在黑人、西班牙裔或低收入居民比例较高的地区,共享单车出行在统计上存在显著差异,但公交车乘客量没有这种差异。鉴于美国的小县城通常不那么多样化,如果不加以解决,从长远来看,不公平的准入可能会恶化。这项案例研究的结果可能有助于为美国其他小县城,特别是那些没有资源收集微观数据、以大学为基地或大部分人口免费乘坐公共交通的县,提供有关城市流动性和公平性的未来地方政策信息。

A case study on the impacts of COVID-19 on bus ridership, bikesharing, and equity in a small U.S. county

Several studies highlight how the coronavirus (COVID-19) lockdowns have permanently changed the way people travel, but there has been less focus on impacts outside major metropolitan areas, where alternative transportation modes are more limited or scarce. This case study focuses on the long-term effects of the COVID-19 lockdowns on public transit and bikesharing using micro-level data in Lane County, Oregon. Lane County reflects the nearly 3,000 small U.S. counties that are a mixture of rural and urban landscape. Findings show that both transportation modes have begun to recover after large reductions in usage, though bikesharing seems to be less resilient relative to public transit 18-months post-lockdown. Additionally, findings show changes in bus ridership and bikeshare trips differed based on sociodemographic characteristics, though bikeshare trips were more sensitive to change. For example, there were statistically significant differences in bikeshare trips among tracts with a higher proportion of Black, Hispanic, or low-income residents, but no such differences for bus ridership. Given that small U.S. counties are typically less diverse, if not addressed, inequitable access could worsen in the long-run. Results from this case study could help inform other small U.S. counties, especially those that do not have the resources to collect micro-level data and are based around a university or where public transit is free for a large portion of the population, on future local policies regarding urban mobility and equity.
