The latest outputs from researchers, alumni and friends at the UCL Centre for Advanced Spatial Analysis (CASA).
Michael Mehaffy and Nikos Salingaros have written a nice paper on networks which is the online journal Biourbanism. They quote from E. Forster who made much in stories of the fact that we need to ‘connect’. His novella The Machine … Continue reading →
Continue reading »Social physics, scaling, urban informatics, energy in cities are all elements of a science of cities. The recent article by Solecki, Seto, and Marcotullio ‘It’s Time for an Urbanization Science’ in the magazine Environment develops yet another notion of what … Continue reading →
Continue reading »In 1999, Jeff Kenworthy & colleagues (Laube & Zeibots) published a paper entitled “Towards a Science of Cities“. Jeff recently drew my attention to this and I post it here as it is key to many indicators of city structure … Continue reading →
Continue reading »This interesting meeting is being held in Oporto, Portugal and involves a reassessment of progress and problems in this field of simulation. I am giving the keynote at 2-30pm November 8th -19th and the pdf of my power point can … Continue reading →
Continue reading »Singapore World Cities Summit, Singapore WasteMetAsia sessions, today. Talking on how complexity theory can be used to think about waste in cities – of course it can be used to think about anything in cities, but here are some improvised … Continue reading →
Continue reading »A deluge of data makes cities laboratories for those seeking to run them better. Nice summary from Ludwig Siegele in this week’s Economist, online version I think. Merging smart cities and new scaling laws. And reference to the forthcoming meeting … Continue reading →
Continue reading »My talk at CPGIS this morning is about how we might use all our new flow data to build new models to explore how city systems fail. This is more a talk about what we would like to do, rather … Continue reading →
Continue reading »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 … Continue reading →
Continue reading »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 … Continue reading →
Continue reading »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, … Continue reading →
Continue reading »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 … Continue reading →
Continue reading »Topical visualisations of flows: so simple, so effective. How we can visualise the flow of debt in the west between countries by the BBC and even better by the New York Times which introduces scenarios about future flows, reflecting contagion, phase … Continue reading →
Continue reading »BitCity tomorrow (3rd November) at Columbia (NYC). Click left for my presentation on Cities as Flow Systems. Talks about CASA’s Oyster Card, Bikes, Networks, and LUTI model projects and how they can be used to look at fractured networks. Thanks … Continue reading →
Continue reading »Amazing what you discover when you search the web. Couldn’t find Ravenstein’s 1888 map that Waldo Tobler sent me as a detailed scan. Its framed in my room at UCL and somewhere on the web I know. What I did … Continue reading →
Continue reading »The TfL Oyster Card Tube and Train flow volumes over 24 hrs at 666 (don’t worry about the number) hubs reveal classic diurnal peaks but the profiles are far from power laws. If anything, they are lognormal. Watch the Vimeo Clip. … Continue reading →
Continue reading »Bit of an experiment really as it is the weekend. Thought I would embed some background music into the website and the album Flux from the indie group Broken Cities reflects the themes of a Science of Cities. And the … Continue reading →
Continue reading »Inspired by Victor Gruen’s heart of the city posted here a little while ago, Jon Reade’s 24 hour movie of traffic on London’s railways (tube+overground) moves us a little closer to Leonardo’s analogy of the city as body. More biology perhaps … Continue reading →
Continue reading »…. 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 … Continue reading →
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 … Continue reading →
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, … Continue reading →
The analogy between the city and the human body goes back to Leonardo. The heart of the city, said Victor Gruen, pumps its people as flows of traffic to keep it energized as an exchange mechanism. Great visualization of the … Continue reading →
Anil Bawa-Cavia, on CASA’s SCALE project, is researching data from the social networking site FourSquare. At the PURBA last week, he won the prize for the best doctoral paper. Read it. Full-text PDF size: 688 Kb.
