Geometry of Urban Order
Marc Barthelemy, Geoff Boeing
Urban street networks are modeled as spatial graphs whose geometry reflects planning, history, and physical constraints. Global orientation measures describe the overall order of a…
Crowding controls the scaling of bus frequency with demand
Siddharth Patwardhan, Şirag Erkol, Filippo Radicchi +1
Cities must allocate limited resources to maintain mobility, with uncertainties about the resulting state of the system. Analyzing roughly 3,000 bus routes with more than 4 billion…
Universal Model of Urban Street Networks
Marc Barthelemy, Geoff Boeing
Analyzing 9,000 urban areas' street networks, we identify properties, including extreme betweenness centrality heterogeneity, that typical spatial network models fail to explain. A…
From lines to networks
Marc Barthelemy
Many real-world networks, ranging from subway systems to polymer structures and fungal mycelia, do not form by the incremental addition of individual nodes but instead grow through…
Critical demand in a stochastic model of flows in supply networks
Yannick Feld, Marc Barthelemy
Supply networks are essential for modern production, yet their critical properties remain understudied. We present a stochastic model with random production capacities to analyze m…
Surfacic networks
Marc Barthelemy, Geoff Boeing, Alain Chiarada +1
Surfacic networks are structures built upon a two-dimensional manifold. Many systems, including transportation networks and various urban networks, fall into this category. The flu…
Fragility of Chess positions: measure, universality and tipping points
Marc Barthelemy
We introduce a novel metric to quantify the fragility of chess positions using the interaction graph of pieces. This fragility score captures the tension within a position and…
A review of the structure of street networks
Marc Barthelemy, Geoff Boeing
We review measures of street network structure proposed in the recent literature, establish their relevance to practice, and identify open challenges facing researchers. These meas…
A typology of activities over a century of urban growth
Julie Gravier, Marc Barthelemy
Contemporary literature on the dynamics of economic activities in growing cities mainly focused on a few years or decades time frames. Using a new geo-historical database construct…
A Stochastic Block Hypergraph model
Alexis Pister, Marc Barthelemy
The stochastic block model is widely used to generate graphs with a community structure, but no simple alternative currently exists for hypergraphs, in which more than two nodes ca…
Symmetry breaking in optimal transport networks
Siddharth Patwardhan, Marc Barthelemy, Sirag Erkol +2
Despite its importance for practical applications, not much is known about the optimal shape of a network that connects in an efficient way a set of points. This problem can be for…
Structure of road networks and the shape of the macroscopic fundamental diagram
Erwan Taillanter, Andreas Schadschneider, Marc Barthelemy
The macroscopic fundamental diagram (MFD) is a large scale description of the traffic in a urban area and relates the average car flow to the average car density. This MFD has been…
