Cities as Brains

As cities get bigger, their capacity to innovate (hence their wealth) appears to scale super-linearly (with their size).  But the idea that ‘big cities’ have ‘big brains’ and are smarter, is problematic as is their scaling and allometry. Read Changizi & Destefano.

Movies Are Now Online

Put my experiments with movies online. The current one is that based on linking our desktop LUTI model to Google Earth. Click here. No sound yet and still getting used to the capture. Click to explore the full Tyndall & Arcadia movies with golden oldies.

The Oldest Flow Map

…. according to the great cartographer Arthur Robinson, the two maps of traffic between Dublin and the rest of Ireland by Lt. Harness of the British Army in 1837, are the oldest. Mapped for the Irish Railway Commissioners prior to construction of the railway. Are these actually the first?

Visualising Fast Flows

Aaron Koblin has produced some fantastic animations of airline flows reminiscent of some of Joan Serras’ work on our SIMULACRA blog. Check out Aaron’s flow stuff. He uses Google Maps to zoom in and out. Also dig into his web site for very innovative animations of fast flows and fluxes.

Procedures to Generate Fractal Cityscapes

For a decade or more, computer scientists have used procedural logics (grammars) to generate urban morphologies. The paper by Li and Miller uses such recursive procedures similar to those we used a while ago to generate fractal cityscapes. Watch their movie. We need to explore this CS stuff more.

Cellular Urban Regeneration

Most of urban dynamics involve activities that are in situ already. Here we present a populist foray into simulating the impact of regeneration on Stratford (the site of the Olympics Games) in east London using our Tyndall LUTI model. Read the paper.

Movements from Point Data

Constructing flows from where people are located at different points in time is usually hard and often impossible for large populations. You can only do it for individuals if you know the actual locations and order visited: posted on vimeo, and tweeted.
