Understanding the long-term impact that changes in a city's transportation infrastructure have on its spatial interactions remains a challenge. The difficulty arises from the fact that the real impact may not be revealed in static or aggregated mobility measures, as these are remarkably robust to perturbations. More generally, the lack of longitudinal, cross-sectional data demonstrating the evolution of spatial interactions at a meaningful urban scale also hinders us from evaluating the…

Urban socioeconomic patterns revealed through morphology of travel routes

The city is a complex system that evolves through its inherent social and economic interactions. Mediating the movements of people and resources, urban street networks o↵er a spatial footprint of

Understanding the Spatial and Temporal Activity Patterns of Subway Mobility Flows

This study provides a method for modelling the effects of social features on mobility flows and for predicting the spatial-temporal mobility flows of newly built subway stations.

Spatio-Temporal Understanding and Representation of Transformative Urban Mobility and Trip Patterns, A Review.

The spatio-temporal models evaluated in this review can be used in a wide range of mobility studies suggesting trip patterns and related variables are significantly affected by spatial and non-spatial impacts.

Portraying Temporal Dynamics of Urban Spatial Divisions with Mobile Phone Positioning Data: A Complex Network Approach

Great potential of large-scale mobility data is demonstrated in supporting intelligent spatial decision making and providing valuable knowledge to the urban planning sectors with a high level of variability in spatial divisions at different times of day.

Morphology of travel routes and the organization of cities

The shape of travel routes in 92 cities is investigated and a metric called inness is defined which reveals connections between common urban features in cities with similar inness profiles, suggesting a strong connection between urban development, increasing physical connectivity, and diversity of road hierarchies.

Revisiting the coupling between accessibility and population growth

A model is proposed that integrates the stochastic internal variation of the municipalitie's population and an inter-urban migration term that is proportional to the accessibility variation and has a limited time duration and sheds a new light on the impact of transportation modes on city growth.

Interplay between urban communities and human‐crowd mobility: A study using contributed geospatial data sources

The results obtained by various empirical analyses suggest that the modified community‐constrained origin–destination flow estimation models exhibit better performance levels than those of alternative conventional mobility models.

Patterns and Limitations of Urban Human Mobility Resilience under the Influence of Multiple Types of Natural Disaster

This study examines how natural disasters influence human mobility patterns in urban populations using individuals’ movement data collected from Twitter, suggesting that the power-law can describe human mobility in most cases and that human Mobility patterns observed in steady states are often correlated with those in perturbed states.



Structure of Urban Movements: Polycentric Activity and Entangled Hierarchical Flows

The large scale, real-time ‘Oyster’ card database of individual person movements in the London subway is utilized in an unprecedented manner to reveal the structure and organization of the city.

Multiscale mobility networks and the spatial spreading of infectious diseases

The present approach outlines the possibility for the definition of layered computational approaches where different modeling assumptions and granularities can be used consistently in a unifying multiscale framework.

Universal predictability of mobility patterns in cities

This work presents a population-weighted opportunities model without any adjustable parameters to capture the underlying driving force accounting for human mobility patterns at the city scale, and finds that insofar as the spatial distribution of population is available, it offers universal prediction of mobility patterns in good agreement with real observations.

A universal model for mobility and migration patterns

A stochastic process capturing local mobility decisions that helps to derive commuting and mobility fluxes that require as input only information on the population distribution is introduced, significantly improving the predictive accuracy of most of the phenomena affected by mobility and transport processes.

Understanding individual human mobility patterns

The trajectory of 100,000 anonymized mobile phone users whose position is tracked for a six-month period is studied, finding that, in contrast with the random trajectories predicted by the prevailing Lévy flight and random walk models, human trajectories show a high degree of temporal and spatial regularity.

The worldwide air transportation network: Anomalous centrality, community structure, and cities' global roles

It is found that the worldwide air transportation network is a scale-free small-world network, and it is demonstrated that the most connected cities are not necessarily the most central, resulting in anomalous values of the centrality.

Urban characteristics attributable to density-driven tie formation

Here it is demonstrated that the model provides a robust and accurate fit for the dependency of city characteristics with city-size, ranging from individual-level dyadic interactions to population level variables without the need to appeal to heterogeneity, modularity, specialization or hierarchy.

The Origins of Scaling in Cities

All cities may evolve according to a small set of basic principles that operate locally, which are shown to be independent of city size and might be a useful means to evaluate urban planning strategies.

Uncovering space-independent communities in spatial networks

This paper argues in this paper for a careful treatment of the constraints imposed by space on network topology and proposes a modularity function adapted to spatial networks for community detection and focuses on the problem of community detection.
