论文摘要
旨在阻碍COVID-19-19的政策是历史上最大的关键事件之一。对这一过程的理解对于制作和调整污水策划后的救济至关重要。在这项工作中，我们通过来自1300万Facebook用户的地理位置数据进行大规模数据分析，这些数据如何影响法国，意大利和英国的移动性模式。我们发现，运动网络中总体效率的总体降低伴随着地理碎片，并大量降低了远距离连接。然而，影响国家根据其最初的移动性结构而有所不同。确实，我们发现锁定后的移动性网络更加集中在法国和英国的情况下，并且在意大利分布更多。可以通过渗透来近似这样的过程，以量化锁定的实质影响。
The policies implemented to hinder the COVID-19 outbreak represent one of the largest critical events in history. The understanding of this process is fundamental for crafting and tailoring post-disaster relief. In this work we perform a massive data analysis, through geolocalized data from 13M Facebook users, on how such a stress affected mobility patterns in France, Italy and UK. We find that the general reduction of the overall efficiency in the network of movements is accompanied by geographical fragmentation with a massive reduction of long-range connections. The impact, however, differs among nations according to their initial mobility structure. Indeed, we find that the mobility network after the lockdown is more concentrated in the case of France and UK and more distributed in Italy. Such a process can be approximated through percolation to quantify the substantial impact of the lockdown.
