We explore the individual decision-making processes of commuters using various forms of transport within a city, forming a modal share which is then built into a dynamical model using travel time as the key variable. From a randomised start in …
Detecting cities with high intermediacy in the African urban network
We construct Africa’s urban network obtained from OpenStreetMap road data. City centrality is measured using two indices: by the degree of cities, so the number of roads that connect it, and by the intermediacy, or the number of intracity journeys …
Boosting African cities’ resilience to climate change
Here we estimate the availability of green spaces in 5 625 urban agglomerations in Africa with 10 000 inhabitants and above.
Constructing a simplified interurban road network based on crowdsourced geodata
We present a method to construct a simplified and connected urban network. Some network nodes are cities, and others are “transport nodes” representing road crossings or other types of infrastructure.
Scaling beyond cities
We analyse the scaling behaviour of cities beyond their boundaries by considering the emergence and growth of nearby cities.

Reconciling big data and thick data to advance the new urban science and smart city governance
Amid growing enthusiasm for a ”new urban science” and ”smart city” approaches to urban management, ”big data” is expected to create radical new opportunities for urban research and practice. Meanwhile, anthropologists, sociologists, and human geographers, among others, generate highly contextualized …
Mobility between Colombian cities is predominantly repeat and return migration
A new model is presented for representing onward and repeat human migration.
Weekly Crime Concentration
Crime frequently happens in a few places, is mainly suffered and committed by some individuals and now, we know that it is highly concentrated in moments of the week.
