    Towards a Science of Cities

    Posted on Saturday 16 February 2013 by Michael Batty

    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 →

    Urban Transformations and Urban Structure

    Posted on Thursday 15 November 2012 by Michael Batty

    Check out Luc D’Acci’s Blog. He has some very interesting projects on mega cities and the internal structure of cities which blends lots of ideas from economics and complexity theory with spatial structures and patterns. Some papers are downloadable

    Fractal Architecture

    Posted on Thursday 19 July 2012 by Michael Batty

    Much of this site is about the morphology of cities using fractal geometry as one of the key unifying themes. But it is in architecture that the real modularity of fractals has become a central feature in design. Harris’s exposition … Continue reading →

    Complexity Theories of Cities Have Come of Age

    Posted on Monday 13 February 2012 by Michael Batty

    A new book on complexity and cities edited by Juval Portugali, Han Meyer, Egbert Stolk and Ekim Tan with the intriguing title that what we do has come of age. Well maybe, maybe not, I leave you to be the … Continue reading →

    Města, komplexita a vznikající řád

    Posted on Tuesday 15 November 2011 by Michael Batty

    Well I only know what it means because others translated it for me – click left image for it in Czech and here for it in English as I posted it once before as Cities, Complexity and Emergent Order. The … Continue reading →

    Complexity in Regional Science: The Alonso Lecture

    Posted on Saturday 12 November 2011 by Michael Batty

    Here is my lecture given at the North American Regional Science Association Annual Conference in Miami, 11th Nov 2011. It is as good a summary as I can muster of complexity theory applied to cities & regions. I focus on … Continue reading →

    Paris Plages – the City Beach

    Posted on Monday 25 July 2011 by Fabian Neuhaus

    Transformations towards opening the waterside of cities particularly in Europe are taking place for the last fifteen years. Rivers and lake side areas are being discovered as recreation areas of high value. What was formerly waste land or industrial ar…

    Network Science, A Guide

    Posted on Friday 22 July 2011 by Michael Batty

    A science of cities is rooted in networks that deliver energy and information to the components that make up a functioning urban system. This one page guide takes you to the key sites, people, books, papers, data and software associated … Continue reading →

    The Heart of the City

    Posted on Wednesday 6 July 2011 by Michael Batty

    Written by Victor Gruen in 1964 who said “I can visualize a metropolitan organism in which cells, each one consisting of a nucleus and a protoplasm, are combined into clusterizations to form specialised organs like towns…..” He portrayed this idealised … Continue reading →

    Procedures to Generate Fractal Cityscapes

    Posted on Friday 24 June 2011 by Michael Batty

    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 … Continue reading →

    Cities as Biologies

    Posted on Sunday 19 June 2011 by jmichaelbatty

    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 →

    Architecture in the Science of Cities

    Posted on Thursday 16 June 2011 by jmichaelbatty

    A significant movement in architecture deals with complexity theory with strong resonance to a science of cities. In 2004, the journal Katarxis Nº 3 reported this new wave with extracts from the writings of Jacobs, Salingaros, and Alexander.
