论文摘要
我们提供了一系列网络，描述了2020年至2021年之间墨西哥市政当局之间的旅行模式。使用匿名移动设备地理位置数据，我们构建了定向的，加权网络，代表了市政当局之间的（归一化）旅行。我们分析了全局（图总重量），本地（中心度度量）和中尺度（社区结构）网络特征的变化。我们观察到这些特征的变化与COVID-19限制和人口规模等因素有关。总的来说，2020年初（最初的COVID-19限制实施）的事件引起了网络功能的更严重变化，而后来的事件对网络功能的影响较小。我们认为，这些网络对于整个运输，基础设施规划，流行病控制和网络科学领域的研究人员和决策者将很有用。
We present a collection of networks that describe the travel patterns between municipalities in Mexico between 2020 and 2021. Using anonymized mobile device geo-location data we constructed directed, weighted networks representing the (normalized) volume of travels between municipalities. We analysed changes in global (graph total weight sum), local (centrality measures), and mesoscale (community structure) network features. We observe that changes in these features are associated with factors such as Covid-19 restrictions and population size. In general, events in early 2020 (when initial Covid-19 restrictions were implemented) induced more intense changes in network features, whereas later events had a less notable impact in network features. We believe these networks will be useful for researchers and decision makers in the areas of transportation, infrastructure planning, epidemic control and network science at large.
