Several Multiplexes in the Same City: The Role of Socioeconomic Differences in Urban Mobility

Abstract

In this work we analyze the architecture of real urban mobility networks from the multiplex perspective. In particular, based on empirical data about the mobility patterns in the cities of Bogotá and Medellín, each city is represented by six multiplex networks, each one representing the origin-destination trips performed by a subset of the population corresponding to a particular socioeconomic status. The nodes of each multiplex are the different urban locations whereas links represent the existence of a trip from one node (origin) to another (destination). On the other hand, the different layers of each multiplex correspond to the different existing transportation modes. By exploiting the characterization of multiplex transportation networks combining different transportation modes, we aim at characterizing the mobility patterns of each subset of the population. Our results show that the socioeconomic characteristics of the population have an extraordinary impact in the layer organization of these multiplex systems.

An analytical framework to nowcast well-being using mobile phone data

“…Lotero et al analyze the architecture of urban mobility networks in two Latin-American cities from the multiplex perspective. They discover that the socio-economic characteristics of the population have an extraordinary impact in the layer organization of these multiplex systems [33]. Amini et al use mobile phone data to compare human mobility patterns of a developing country (Ivory Coast) and a developed country (Portugal).…”

Impact of temporal scales and recurrent mobility patterns on the unfolding of epidemics

“…Notwithstanding, some of the assumptions are still far from being realistic. In this sense, our formalism paves the way to the elaboration of more realistic frameworks by considering other contagion mechanisms like those associated to vector-borne diseases [38,39], or by including more realistic scenarios regarding mobility such as the multiplex nature of human flows [40][41][42], the existence of mobility patterns beyond recurrent movements [43][44][45] or the modification of human mobility patterns as a response to epidemic outbreaks [16,46].…”

Gender Patterns of Human Mobility in Colombia: Reexamining Ravenstein’s Laws of Migration

“…The characterisation of the travel's temporal features, instead, unveiled unexpected features induced by gender. The analysis of the percentage of travels made along the day, grouped according to either occupation or purpose, highlights that each class of travels displays a specific temporal pattern, which is different from its aggregated counterpart [9]. Such phenomenon constitutes one of the hallmarks of complex systems, which is usually encapsulated by the statement "more is different" [1].…”

“…Some models on mobility assume that all travellers are -more or less -the same, disregarding the wealth of attributes discriminating one social group from another. Conversely, other studies demonstrate that social demographic attributes like socio-economic status do play a role in mobility [9]. Amidst the plethora of attributes available, gender is a key one because men and women can emerge alternative behaviours [11].…”

“…In this work, we study the gender-based spatiotemporal differences in urban mobility taking place within the Medellín's metropolitan area (known as Aburrá Valley) in Colombia in two distinct years, 2005 and 2017. Using an approach similar to the one used in [9,10], we find that despite more than one century has passed since Ravenstein's study, women still make shorter trips -remaining closer to their "homes," -and that employment continues to play a considerable role in mobility. Furthermore, our results are in agreement with those of a recent study based on Chilean mobile phone data by Gauvin et al [6] which found, among other things, that men tend to visit more diverse places than women.…”
