This conference is the seventh in a by-now very well established meeting held each June in Cambridge UK, which brings together those working on land use transport interaction/integration models (LUTI models) in the narrower sense and more generally on urban simulation models. Although initially set up to continue work on aggregate land use and transportation models, it has broadened to include other kinds of models and this year there are interesting papers on very large scale models such as UrbanSim, PECAS and TRANUS as well as cellular automata models like SLEUTH. The programme is here and those wanting the papers should contact the authors. During the meeting we have had a session dealing with the contributions of Lionel March to urban modelling. I tweeted about this a couple of weeks ago but here is my contribution – the PDF of my talk about my work with Lionel some 44 years ago when we were both at the University of Waterloo in Engineering. Lionel of course set up the Centre for Land Use and Built Form Studies that morphed into the Martin Centre (at the University of Cambridge’s School of Architecture) in the mid 1970s. Much of what goes on in LUTI modelling can be traced to Lionel and I am not being melodramatic. My talk recounts what we did with probability theory and spatial interaction and how we tried to fashion ideas about priors, posteriors, minimum information and so on. There is much more to say about Lionel’s contributions but readers might be interested in my own thoughts which are in the attached PDF. Enjoy.
Infrastructure has become another hot word in post-industrial economies that are busy figuring out how they can renew all the physical plant that was constructed during their industrial past. The UK has established a National Infrastructure Commission amidst a flurry of proposed new initiatives involving high speed rail, and other new rail lines, a focus on new housing, as well as a continuing concern for ever faster broadband, specifically based on G5 technologies. American too, notwithstanding the President’s pronouncements, is also initiating new approach’s to established and renewing infrastructure from roads to bridges to airports.
Infrastructure, however, no longer relates to simply physical things, information infrastructure is hot on the agenda while social infrastructure pertains to all our organisational and indeed socially responsible administration that emerged during the 20th century and badly needs renewing. In the current editorial in Environment and Planning B, I summarise some of the key points about renewing our infrastructure. Many new kinds of models are being fashioned to deal with such problems which are now spatially extensive in a way their precursors were not, and integrating different sectors is now one of the key issues so that the wider impacts of new infrastructure can be assessed, as for example in the MISTRAL models being developed by a consortium of research groups in the UK.
This new book edited by Tigran Haas and Hans Westlund from KTH is a collection of interesting and somewhat oblique essays on the urban world we have entered. Lot of people you know writing here. Ed Glaeser, Richard Florida, Patrick Adler, Rahul Mehrotra, Felipe Vera, myself, Hans Westlund, Paul Knox, and Richard Sennett – and that is the first part. And then in two more parts: Jessie Poon, Wei Yin, Kaisa Snellman, Jennifer Silva, Carl Frederick, Robert Putnam, Kyle Farrell, Tigran Haas, Fulong Wu, Karima Kourtit, Peter Nijkamp, Edward Soja, Fran Tonkiss, Laura Burkhalter, Manuel Castells, Saskia Sassen, Susan Fainstein, Emily Talen, Michael Neuman, Nadia Nur, Nina-Marie Lister, Duncan McLaren and Julian Agyeman. You can get a sneak preview using some Google Gizmo that is attached to the site.
In the last few decades, many global cities and towns have experienced unprecedented economic, social, and spatial structural change. Today, we find ourselves at the juncture between entering a post-urban and a post-political world, both presenting new challenges to our metropolitan regions, municipalities, and cities. Many megacities, declining regions and towns are experiencing an increase in the number of complex problems regarding internal relationships, governance, and external connections. In particular, a growing disparity exists between citizens that are socially excluded within declining physical and economic realms and those situated in thriving geographic areas. This book conveys how forces of structural change shape the urban landscape.
In The Post-Urban World is divided into three main sections: Spatial Transformations and the New Geography of Cities and Regions; Urbanization, Knowledge Economies, and Social Structuration; and New Cultures in a Post-Political and Post-Resilient World. One important subject covered in this book, in addition to the spatial and economic forces that shape our regions, cities, and neighbourhoods, is the social, cultural, ecological, and psychological aspects which are also critically involved. Additionally, the urban transformation occurring throughout cities is thoroughly discussed. Written by today’s leading experts in urban studies, this book discusses subjects from different theoretical standpoints, as well as various methodological approaches and perspectives; this is alongside the challenges and new solutions for cities and regions in an interconnected world of global economies.
