The COVID-19 pandemic is causing mass disruption to our daily lives. We integrate mobility data from mobile devices and area-level data to study the walking patterns of 1.62 million anonymous users in 10 metropolitan areas in the United States. The data covers the period from mid-February 2020 (pre-lockdown) to late June 2020 (easing of lockdown restrictions). We detect when users were walking, distance walked and time of the walk, and classify each walk as recreational or utilitarian. Our results reveal dramatic declines in walking, particularly utilitarian walking, while recreational walking has recovered and even surpassed pre-pandemic levels. Our findings also demonstrate important social patterns, widening existing inequalities in walking behavior. COVID-19 response measures have a larger impact on walking behavior for those from low-income areas and high use of public transportation. Provision of equal opportunities to support walking is key to opening up our society and economy.
新冠疫情大流行正在严重扰乱我们的日常生活。我们整合了来自移动设备和区域级别的数据，研究了美国 10 个大都市区 162 万名匿名用户的步行模式。这些数据涵盖了 2020 年 2 月中旬（封锁前）到 2020 年 6 月底（封锁限制放宽）的时间段。我们可以检测到用户何时在步行、步行距离和步行时间，并将每次步行分类为娱乐性或实用性。我们的研究结果显示，步行的次数大幅减少，特别是实用性步行，而娱乐性步行已经恢复，甚至超过了疫情前的水平。我们的研究结果还表明了一些重要的社会模式，即步行行为方面的不平等进一步扩大。对于那些来自低收入地区和高度依赖公共交通的人来说，新冠疫情应对措施对他们的步行行为影响更大。提供平等的机会来支持步行是开放我们的社会和经济的关键。
