Mobility Flow
收藏资源简介:
这是一个横跨美国的多尺度动态人流流动数据集,数据从 2019 年 1 月 1 日开始。通过分析由 SafeGraph 提供的数百万匿名手机用户到各个地方的访问轨迹,每日和每周动态的起点-到-目的地 (O-D) 人口流量在三个地理尺度上计算、汇总和推断:人口普查区、县和州。随着时间的推移,如此高时空分辨率的不同地理尺度的人类流动流动数据集可能有助于监测流行病传播动态,为公共卫生政策提供信息,并加深我们对前所未有的公共卫生危机下人类行为变化的理解。
This is a multi-scale dynamic human mobility flow dataset spanning the United States, with data starting from January 1, 2019. By analyzing the visit trajectories of millions of anonymous mobile phone users to various locations provided by SafeGraph, daily and weekly dynamic origin-destination (O-D) population flows are calculated, aggregated, and inferred across three geographic scales: census tracts, counties, and states. Over time, such human mobility datasets with high spatiotemporal resolution across different geographic scales can help monitor epidemic transmission dynamics, inform public health policy-making, and deepen our understanding of changes in human behavior during an unprecedented public health crisis.
