Material and people flows in cities show atoms are bonded together but money and information flows have much greater resonance. The great challenge is not only to build good economic flow models but first to observe and measure them. Pioneering work at Senseable Cities (movie) - a picture of how people spent money during Easter 2011 in Spain.

Joan Serras in CASA is visualising some excellent flow data on the use of 114,000 pubic buses in London over a 24 hour period. Watch his previous Vimeo clip. Soon we will post Jon Reades visulizations of flows on subways and heavy rail from our Oyster card data.

Nothing like a lecture course to force you to publish digital copies of what one has written. Retrieved a 2 page article, more an entry, on spatial interaction from the Encyclopaedia of Geographic Information Science edited by Karen Kemp, Sage, 2007, 417-419. Largely for our Master’s students but relevant to LUTI models. See Models Blog.

We published quite a high profile paper this week in The Lancet Infectious Diseases. Anders Johansson, myself and colleagues wrote a speculative paper on how to generalise the dynamics of SIR (spatial epidemics) models from pedestrian crowding models as part of their new series on Mass Gatherings. Here is the article.
