揭示COVID-19大流行期间纽约市流动模式的关键特征

Revealing Critical Characteristics of Mobility Patterns in New York City during the Onset of COVID-19 Pandemic

摘要:

由于持续的危机,纽约已成为受COVID-19影响最严重的热点之一及疫情中心。本文通过分析纽约市宏观和微观层面的多个数据集,确定了疫情的影响和政府政策对人类流动的有效性。使用与人口密度,总人口流动性,公共轨道交通使用,车辆使用,热点和非热点移动模式,以及人类活动聚集相关的数据源,我们通过在市镇一级汇总数据来分析纽约市的市镇间和市镇内时刻。我们亦评估了2020年3月及4月热点及非热点关注点之间的节点间人口流动。结果显示,从3月中旬开始,该市的人口流动性下降了约80%。进出曼哈顿的行动对公共交通和道路交通的干扰最大。该市于2020年3月1日出现了第一例病例,但只有在3月的第二周,当庇护所订单生效后,才能看到流动性中断。由于人们在家工作并坚持留在家里的命令,曼哈顿看到了最大的中断,无论是区际和区内的运动。但事实证明,由于与热点地区有关的活动增多,曼哈顿的感染传播风险很高。居家限制也导致布鲁克林和皇后区的人口密度增加,因为人们不再通勤到曼哈顿。从这项研究中获得的见解将有助于政策制定者更好地了解人类行为及其对新闻和政府政策的反应。

英文摘要:

New York has become one of the worst-affected COVID-19 hotspots and a pandemic epicenter due to the ongoing crisis. This paper identifies the impact of the pandemic and the effectiveness of government policies on human mobility by analyzing multiple datasets available at both macro and micro levels for the New York City. Using data sources related to population density, aggregated population mobility, public rail transit use, vehicle use, hotspot and non-hotspot movement patterns, and human activity agglomeration, we analyzed the inter-borough and intra-borough moment for New York City by aggregating the data at the borough level. We also assessed the internodal population movement amongst hotspot and non-hotspot points of interest for the month of March and April 2020. Results indicate a drop of about 80% in people's mobility in the city, beginning in mid-March. The movement to and from Manhattan showed the most disruption for both public transit and road traffic. The city saw its first case on March 1, 2020, but disruptions in mobility can be seen only after the second week of March when the shelter in place orders was put in effect. Owing to people working from home and adhering to stay-at-home orders, Manhattan saw the largest disruption to both inter- and intra-borough movement. But the risk of spread of infection in Manhattan turned out to be high because of higher hotspot-linked movements. The stay-at-home restrictions also led to an increased population density in Brooklyn and Queens as people were not commuting to Manhattan. Insights obtained from this study would help policymakers better understand human behavior and their response to the news and governmental policies.
