Flat City; a space syntax derived urban movement network model

by Stephen Read

A model of urban movement dynamics is presented, based on a system of overlaid movement infrastructural networks distinguished by movement scale. This model accounts simply for the space syntax `intelligibility' scattergram, proposing that it is a systematic product of the interaction between two movement centrality efects in two conceptually and functionally separable infrastructural networks. The signifcance of this model consists in the ¯rst place in the fact that it o®ers a simple way of thinking the relation between the two diferent but related levels of spatial integration. It is argued that this relation supports situated intelligibility on the one hand and on the other refers to the emergence of particular place conditions. It is argued that it offers an easily conceivable model to replace the objectivist centre-periphery model, which is at present the default but inadequate model for beginning to think the form of the contemporary city. The extendibility of the idea (through the addition of further infrastructural network layers representing higher scales of mobility and connectivity) also begins to address a fundamental edge problem in the application of conventional space syntax to the metropolitan spatial problematic. It is believed that the model can be adjusted to model other types of city and that in its most general formulation that it may have a generic relevance to the way that urban form may be understood in the way it a®ords situated environmental action, perception and intelligibility.
