From motifs to Lévy flights: Modeling urban mobility in Bogotá's public transport system
Juan F. Alayón-Martínez, Alejandro P. Riascos
In this paper, we study two years of access card validation records from Bogotá's multimodal public transport system, comprising over 2.3 billion trips across bus rapid transit, fe…
Temporal visitation patterns of points of interest in cities on a planetary scale: a network science and machine learning approach
Francisco Betancourt, Alejandro P. Riascos, José L. Mateos
We aim to study the temporal patterns of activity in points of interest of cities around the world. In order to do so, we use the data provided by the online location-based social…
Evolution of transport under cumulative damage in metro systems
L. K. Eraso-Hernandez, A. P. Riascos, T. M. Michelitsch +1
One dominant aspect of cities is transport and massive passenger mobilization which remains a challenge with the increasing demand on the public as cities grow. In addition, public…
A markovian random walk model of epidemic spreading
Michael Bestehorn, Alejandro P. Riascos, Thomas M. Michelitsch +1
We analyze the dynamics of a population of independent random walkers on a graph and develop a simple model of epidemic spreading. We assume that each walker visits independently t…
Aging in transport processes on networks with stochastic cumulative damage
A. P. Riascos, J. Wang-Michelitsch, T. M. Michelitsch
In this paper we explore the evolution of transport capacity on networks with stochastic incidence of damage and accumulation of faults in their connections. For each damaged confi…
Random Multi-Hopper Model. Super-Fast Random Walks on Graphs
Ernesto Estrada, Jean-Charles Delvenne, Naomichi Hatano +4
We develop a model for a random walker with long-range hops on general graphs. This random multi-hopper jumps from a node to any other node in the graph with a probability that dec…
