We model the use of various modes of transport in a city by aggregating Active mobility (A), Public Transport (B) and Cars (C), expressing the modal share of a city by its ABC.
Scaling of the morphology of African cities
Based on the location and surface of nearly 200 million buildings on the continent, we estimate the interbuilding distance of almost six thousand cities. Buildings’ footprint data enable the construction of urban form indicators to compare African cities’ elongation, sprawl, …
A Ubiquitous Collective Tragedy in Transport
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 …
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.
