摘要:

延缓新型冠状病毒(COVID-19)传播的一种方法是通过实施旅行限制政策来减少人类旅行。目前尚不清楚这些政策在抑制流动趋势方面的有效性,因为缺乏描述大流行期间人员流动的基本事实和大规模数据集。这项研究使用从匿名移动设备收集的真实世界基于位置的服务数据,以揭示COVID-19期间和美国“呆在家里”状态下的移动性变化。数据驱动的分析和建模将不到5%的出行次数和人英里数的减少归因于政策的影响。该研究中开发的模型具有很高的预测准确性,可用于通过经验验证的流动性趋势为流行病建模提供信息,并支持对时间敏感的决策过程。

英文摘要:

One approach to delay the spread of the novel coronavirus (COVID-19) is to reduce human travel by imposing travel restriction policies. It is yet unclear how effective those policies are on suppressing the mobility trend due to the lack of ground truth and large-scale dataset describing human mobility during the pandemic. This study uses real-world location-based service data collected from anonymized mobile devices to uncover mobility changes during COVID-19 and under the 'Stay-at-home' state orders in the U.S. The study measures human mobility with two important metrics: daily average number of trips per person and daily average person-miles traveled. The data-driven analysis and modeling attribute less than 5% of the reduction in the number of trips and person-miles traveled to the effect of the policy. The models developed in the study exhibit high prediction accuracy and can be applied to inform epidemics modeling with empirically verified mobility trends and to support time-sensitive decision-making processes.
