论文摘要
人们的流动性数据集在评估锁定措施的影响并将流动性与大流行趋势相关联时，在Covid-19大流行期间发挥了作用。全球两个全球数据集是苹果的移动趋势报告和Google的社区流动性报告。前者不再可用，而后者将在2022年10月停产。因此，将需要新产品。为了确定数据集渗透率的下限，确保了新产品与大型技术产品之间的高依从性，分析了基于380万个智能手机轨迹的独立移动性数据集，以将其信息内容与Google数据集进行比较。该下限被确定为10^-4至10^-3（分别为1个轨迹每10,000和1000人），这表明相对较小的数据集适用于更换大型技术报告。
People mobility data sets played a role during the COVID-19 pandemic in assessing the impact of lockdown measures and correlating mobility with pandemic trends. Two global data sets were Apple's Mobility Trends Reports and Google's Community Mobility Reports. The former is no longer available, while the latter will be discontinued in October 2022. Thus, new products will be required. To establish a lower bound on data set penetration guaranteeing high adherence between new products and the Big Tech products, an independent mobility data set based on 3.8 million smartphone trajectories is analysed to compare its information content with that of the Google data set. This lower bound is determined to be between 10^-4 and 10^-3 (1 trajectory every 10,000 and 1000 people, respectively) suggesting that relatively small data sets are suitable for replacing Big Tech reports.
