The extraction of a clear and simple footprint of the structure of large, weighted and directed networks is a general problem that has relevance for many applications. An important example is seen in origin-destination matrices, which contain the complete information on commuting flows, but are difficult to analyze and compare. We propose here a versatile method, which extracts a coarse-grained signature of mobility networks, under the form of a 2 × 2 matrix that separates the flows into four… 

Revealing latent characteristics of mobility networks with coarse-graining

This paper analyzes the travel demand characteristics of mobility networks through studying a coarse-grained representation of individual trips in a simplified representation of large-scale origin-destination matrices derived from more than 16 million taxi trip records from New York and Chicago.

Mobility Signatures: A Tool for Characterizing Cities Using Intercity Mobility Flows

The mobility signature approach is introduced as a tool for understanding how a city (or a region) is embedded in the wider mobility network and how the SARS-CoV-2 pandemic disrupted the mobility patterns in Finland in the spring of 2020.

Uncovering structural diversity in commuting networks: global and local entropy

It is shown that entropy at the link and node level give different insights on the characteristics of the systems, enabling us to identify employment hubs and interdependencies between and within different parts of the system.

Ranking places in attributed temporal urban mobility networks

The spatio-temporal characteristics of “hotspots” of different types of socio-economic activities as characterized by recently developed attribute-augmented network centrality measures within the urban OD network are studied.

Dissecting the Spatial Structure of Cities from Human Mobility Patterns to Define Functional Urban Boundaries

This work ranks places in 11 of the major Chilean urban regions from a high-resolution human mobility dataset: Official origin-destination (OD) surveys, and proposes a method for further distinguishing urban and rural land-uses within these regions by means of a network centrality measure.

Networks and long-range mobility in cities: A study of more than one billion taxi trips in New York City

Considering the taxi trips as a proxy of human mobility in cities, it might be possible that the long-range mobility found for New York City would be a general feature in other large cities around the world.

The universal visitation law of human mobility.

A simple and robust scaling law is revealed that captures the temporal and spatial spectrum of population movement on the basis of large-scale mobility data from diverse cities around the globe and gives rise to prominent spatial clusters with an area distribution that follows Zipf's law.

Topological indexes and community structure for urban mobility networks: Variations in a business day

This paper studies how topological indexes and community structure changes in a business day in the city of São José dos Campos, Brazil, and calculates topological properties, such as degree, clustering coefficient and diameter, and the network’s community structure.

Detecting the dynamics of urban structure through spatial network analysis

Singapore, even from such a short time series, is developing rapidly towards a polycentric urban form, where new subcenters and communities are emerging largely in line with the city’s master plan.

Cross-Checking Different Sources of Mobility Information

A cross-check analysis by comparing results obtained with data collected from three different sources: Twitter, census, and cell phones to assess the correlation between the datasets on different aspects: the spatial distribution of people concentration, the temporal evolution of people density, and the mobility patterns of individuals.

From mobile phone data to the spatial structure of cities

An urban dilatation index is defined which measures how the average distance between individuals evolves during the day, allowing us to highlight different types of city structure, and a parameter free method to detect hotspots, the most crowded places in the city is proposed.

Surprisingly, while there are variations in human movement in different cities, this analysis shows that those are predominantly due to different distributions of places across different urban environments.

A review of urban computing for mobile phone traces: current methods, challenges and opportunities

Three classes of methods to extract information from triangulated mobile phone signals are presented, and applications with different goals in spatiotemporal analysis and urban modeling are described, to demonstrate the state-of-the-art algorithms that can be adapted to triangulation data for the context of urban computing and modeling applications.

The New Science of Cities

In The New Science of Cities, Michael Batty suggests that to understand cities we must view them not simply as places in space but as systems of networks and flows. To understand space, he argues, we

This work applies mobile phone call detail records to a broad range of datasets, showing that home-work time distributions and average values within a single region are indeed largely independent of commute distance or country–despite substantial spatial and infrastructural differences.

Daily human mobility can be reproduced by an analytically tractable framework for Markov chains by modelling periods of high-frequency trips followed by periods of lower activity as the key ingredient.
