Stochastic equations and cities
Marc Barthelemy
Stochastic equations constitute a major ingredient in many branches of science, from physics to biology and engineering. Not surprisingly, they appear in many quantitative studies…
Modeling the spatial dynamics of income in cities
Vincent Verbavatz, Marc Barthelemy
Urban inequality is a major challenge for cities in the 21st century. This inequality is reflected in the spatial income structure of cities which evolves in time through various p…
Statistical analysis of chess games: space control and tipping points
Marc Barthelemy
Moves in chess games are usually analyzed on a case-by-case basis by professional players, but thanks to the availability of large game databases, we can envision another approach…
The distorting lens of human mobility data
Riccardo Gallotti, Davide Maniscalco, Marc Barthelemy +1
The description of complex human mobility patterns is at the core of many important applications ranging from urbanism and transportation to epidemics containment. Data about colle…
Spatial Structure of City Population Growth
Sandro M. Reia, P. Suresh C. Rao, Marc Barthelemy +1
We show here that population growth, resolved at the county level, is spatially heterogeneous both among and within the U.S. metropolitan statistical areas. Our analysis of data fo…
Evolution of road infrastructures in large urban areas
Erwan Taillanter, Marc Barthelemy
Most cities in the US and in the world were organized around car traffic. In particular, large structures such as urban freeways or ring roads were built for reducing car traffic c…
A dominance tree approach to systems of cities
Thomas Louail, Marc Barthelemy
Characterizing the spatial organization of urban systems is a challenge which points to the more general problem of describing marked point processes in spatial statistics. We prop…
Local impacts on road networks and access to critical locations during extreme floods
Simone Loreti, Enrico Ser-Giacomi, Andreas Zischg +2
Floods affected more than 2 billion people worldwide from 1998 to 2017 and their occurrence is expected to increase due to climate warming, population growth and rapid urbanization…
Betweenness centrality in dense spatial networks
Vincent Verbavatz, Marc Barthelemy
The betweenness centrality (BC) is an important quantity for understanding the structure of complex large networks. However, its calculation is in general difficult and known in si…
Empirical evidence for a jamming transition in urban traffic
Erwan Taillanter, Marc Barthelemy
Understanding the mechanisms leading to the formation and the propagation of traffic jams in large cities is of crucial importance for urban planning and traffic management. Many s…
The growth equation of cities
Vincent Verbavatz, Marc Barthelemy
The science of cities seeks to understand and explain regularities observed in the world's major urban systems. Modelling the population evolution of cities is at the core of this…
Access to mass rapid transit in OECD urban areas
Vincent Verbavatz, Marc Barthelemy
As mitigating car traffic in cities has become paramount to abate climate change effects, fostering public transport in cities appears ever-more appealing. A key ingredient in that…
Scenarios for a post-COVID-19 world airline network
Jiachen Ye, Peng Ji, Marc Barthelemy
The airline industry was severely hit by the COVID-19 crisis with an average demand decrease of about (IATA, April 2020) which triggered already several bankruptcies of airl…
The effect of interurban movements on the spatial distribution of population in China
Jiachen Ye, Qitong Hu, Peng Ji +1
Understanding how interurban movements can modify the spatial distribution of the population is important for transport planning but is also a fundamental ingredient for epidemic m…
Revisiting the coupling between accessibility and population growth
Valerio Volpati, Marc Barthelemy
The coupling between population growth and transport accessibility has been an elusive problem for more than 60 years now. Due to the lack of theoretical foundations, most of the s…
Tomography of scaling
Marc Barthelemy
Scaling describes how a given quantity that characterizes a system varies with its size . For most complex systems it is of the form with a nontrivial value of t…
Modeling cities
Marc Barthelemy
Cities are systems with a large number of constituents and agents interacting with each other and can be considered as emblematic of complex systems. Modeling these systems is a re…
The statistical physics of Cities
Marc Barthelemy
Challenges due to the rapid urbanization of the world -- especially in emerging countries -- range from an increasing dependence on energy, to air pollution, socio-spatial inequali…
The optimal geometry of transportation networks
David Aldous, Marc Barthelemy
Motivated by the shape of transportation networks such as subways, we consider a distribution of points in the plane and ask for the network of given length that is optimal…
Efficiency and shrinking in evolving networks
Arianna Bottinelli, Marco Gherardi, Marc Barthelemy
Characterizing the spatio-temporal evolution of networks is a central topic in many disciplines. While network expansion has been studied thoroughly, less is known about how empiri…
Critical factors for mitigating car traffic in cities
Vincent Verbavatz, Marc Barthelemy
Car traffic in urban systems has been studied intensely in past decades but models are either limited to a specific aspect of traffic or applied to a specific region. Despite the i…
The spatial organization of the population density in cities
Valerio Volpati, Marc Barthelemy
Although the average population density of a city is an extremely simple indicator, it is often used as a determinant factor for describing various aspects of urban phenomena. On t…
From global scaling to the dynamics of individual cities
Jules Depersin, Marc Barthelemy
Scaling has been proposed as a powerful tool to analyze the properties of complex systems, and in particular for cities where it describes how various properties change with popula…
Human Mobility: Models and Applications
Hugo Barbosa-Filho, Marc Barthelemy, Gourab Ghoshal +7
Recent years have witnessed an explosion of extensive geolocated datasets related to human movement, enabling scientists to quantitatively study individual and collective mobility…
