Until Bill comes back from France, it could be a good start to read Stephen Town's report on New Urban Urbanism and other approaches to designing out crime: Design Against Crime: Guidance for the Design of Residential Areas, published by the European Union Commission in 2003. I had this article somewhere, but only in paper form. There is an option to try and reach this report via http://www.designagainstcrime.org/. Also, to get a grip of how space syntax could be used for evaluating the effect of built environment on the risk of crime, and the temporal/spatial distributions of crime, you can read: Alford, V. (1996). "Crime and space in the Inner City." Urban Design Studies 2: 45-76. Shu, S. C. F., Huang, J.N.H. (2003). Spatial configuration and Vulnerability of Residential Burglary: A case study of a city in Taiwan. 4th International Space Syntax Symposium, London. Shu's PhD thesis: Shu, S. (2000). Crime in Urban Layouts, University of London. About "constitution": Major, M. D. (2001). When is a door more than a door? 3rd International Space Syntax Symposium Atlanta 2001, Atlanta. You may know there are also lots of discussions on the web about new urbanism. Just as links to warm up for the discussion: http://www.operationscorpion.org.uk/design_out_crime/crime_urbanism.htm http://www.reason.com/0502/fe.st.crime.shtml http://www.planetizen.com/oped/cmt_item.php?id=1312 http://www.planetizen.com/oped/item.php?id=146 I'm sure Bill will provide more connections and explanations as he recently gave a talk at the Congress for New Urbanism in Pasadena, and he has been focusing on the positive and negative aspects of not only new urbanism but also of general conceptual approaches to the relationship between crime and the built environment. We are trying to bring more of an analytical light into this issue using a London crime database that covers 5 years, together with a GIS dataset from the corresponding council. Please do not hesitate to contact us whenever you need during your study. (and sorry I could not reply to this before, there was a problem with my subscription to the list. ) Ozlem
