Data from: Rich do not rise early: spatio-temporal patterns in the mobility networks of different socio-economic classes

We analyse the urban mobility in the cities of Medellín and Manizales
(Colombia). Each city is represented by six mobility networks, each one
encoding the origin-destination trips performed by a subset of the
population corresponding to a particular socio-economic status. The nodes
of each network are the different urban locations whereas links account
for the existence of a trip between two different areas of the city. We
study the main structural properties of these mobility networks by
focusing on their spatio-temporal patterns. Our goal is to relate these
patterns with the partition into six socio-economic compartments of these
two societies. Our results show that spatial and temporal patterns vary
across these socio-economic groups. In particular, the two datasets show
that as wealth increases the early-morning activity is delayed, the midday
peak becomes smoother and the spatial distribution of trips becomes more
localized.

我们对哥伦比亚麦德林（Medellín）和马尼萨莱斯（Manizales）两座城市的城市流动性展开分析。每座城市由六个流动性网络（mobility network）表征，每个网络编码对应特定社会经济地位（socio-economic status）人群子集的起终点出行数据。每个网络的节点（node）为不同城市区位，而连边（link）则表示城市内两个不同区域间存在出行活动。我们通过聚焦其时空模式（spatio-temporal pattern），研究这些流动性网络的主要结构特征。我们的目标是将这些模式与两座城市社会划分为六个社会经济分区（socio-economic compartment）的情况关联起来。研究结果表明，不同社会经济分区的时空模式存在差异。具体而言，两个数据集显示，随着财富水平提升，早间活动时间推迟，午间高峰趋于平缓，且出行的空间分布更趋本地化。
