A new theory of space syntax

Relations between different components of urban structure are often measured in aliteral manner, along streets for example, the usual representation being routesbetween junctions which form the nodes of an equivalent planar graph. A popularvariant on this theme ? space syntax ? treats these routes as streets containing one ormore junctions, with the equivalent graph representation being more abstract, basedon relations between the streets which themselves are treated as nodes. In this paper,we articulate space syntax as a specific case of relations between any two sets, in thiscase, streets and their junctions, from which we derive two related representations.The first or primal problem is traditional space syntax based on relations betweenstreets through their junctions; the second or dual problem is the more usualmorphological representation of relations between junctions through their streets.The unifying framework that we propose suggests we shift our focus from the primalproblem where accessibility or distance is associated with lines or streets, to the dualproblem where accessibility is associated with points or junctions. This traditionalrepresentation of accessibility between points rather than between lines is easier tounderstand and makes more sense visually. Our unifying framework enables us toeasily shift from the primal problem to the dual and back, thus providing a muchricher interpretation of the syntax. We develop an appropriate algebra which providesa clearer approach to connectivity and distance in the equivalent graphrepresentations, and we then demonstrate these variants for the primal and dualproblems in one of the first space syntax street network examples, the French villageof Gassin. An immediate consequence of our analysis is that we show how the directconnectivity of streets (or junctions) to one another is highly correlated with thedistance measures used. This suggests that a simplified form of syntax can beoperationalized through counts of streets and junctions in the original street network

Feeling good and feeling safe in the landscape: a `syntactic' approach

Space syntax is a theory and set of tools and techniques for the analysis of spatial configurations. It was developed at UCL in the late 1970s, as an approach to understanding human spatial organisation and to help architects and urban designers to simulate the likely social consequences of their projects. The fundamental proposition of space syntax is that a building or place can be broken down into spatial components, so that an analysis of the interrelations of the components will yield information about the pattern of space that is meaningful and functionally relevant. Over the past thirty years, space syntax has been successfully applied to resolve problems as diverse as master planning entire cities or revealing the imprint of culture in domestic settings. With this in mind, this paper will explore opportunities and challenges of taking a syntactic approach to the spatial analysis of landscape. To the extent that people avoid walking through landscapes in which they feel apprehensive, understanding the spatial characteristics of such environments should enable landscape designers to create vital landscapes that support healthy lifestyles and avoid those conditions where people may feel insecure. The paper will focus on how the tools/techniques of space syntax can be adapted to understand the circumstances in which people feel motivated to explore their local landscape and the spatial factors that may deter people from incorporating walking into their everyday routines

Balancing operating revenues and occupied refurbishment costs 2: a Space Syntax approach to locating hoardings

By placing hoardings in publicly accessible areas while carrying out phased occupied refurbishments, a contractor is temporarily redesigning that area. This reconfiguration affects the normal pedestrian flows through such areas. A technique for the analysis of such flows has been developed under a general area of research called Space Syntax. This demonstrates the extent to which visual barriers both constrain and promote pedestrian movement. The main analytical techniques used are Axial analysis and Visibility Graph Analysis which are based upon lines or areas of visibility. Empirical evidence is presented in observations carried out at London Victoria Station before and during a small refurbishment project involving the temporary closure of a single entrance. This evidence is in line with previous Space Syntax studies. The relationship between changes in the station configuration and visitor numbers to retail outlets suggests the need to place hoardings in such a way that both movement and browsing areas remain spatially separated but visually connected. This is also suggested by previous Space Syntax studies and is incorporated into a brief set of general guidelines for clients and contractors to assist the minimisation of disruption to pedestrian movement in publicly accessible areas

An investigation of the relation of space to society: a discussion on A. Giddens, H. Lefebvre and space syntax

This thesis is dealing with the relation of society and space as a main characteristic for elucidating the design process. More particular is based on the problem which appears both in spatial and social theories of relating entities which ‘are in different scales’. This is the relation of space, which is a local notion, to society, which is a global idea or the relation of society to the everyday life, which is also local and spatial. Thιs thesis attempts to investigate the relation of society to space through this core problem by examining three theories which seem to deal with this issue. These are the Space Syntax Theory of Hillier and Hanson, the Structuration theory of Giddens and the theory of the Production of Space of Lefebvre. The first has an architectural and urban point of view of the matter, the second a sociological and the third a politico-economic. The discussion of the three theories shows that all three grasp an interrelation between society and space although each theory sees this interrelation in a different way. For the Structuration theory space has an important role in the structuration of society, for Space Syntax a constructive role of the generic forms of society and for Lefebvre an instrumental character

Ranking Spaces for Predicting Human Movement in an Urban Environment

A city can be topologically represented as a connectivity graph, consisting of nodes representing individual spaces and links if the corresponding spaces are intersected. It turns out in the space syntax literature that some defined topological metrics can capture human movement rates in individual spaces. In other words, the topological metrics are significantly correlated to human movement rates, and individual spaces can be ranked by the metrics for predicting human movement. However, this correlation has never been well justified. In this paper, we study the same issue by applying the weighted PageRank algorithm to the connectivity graph or space-space topology for ranking the individual spaces, and find surprisingly that (1) the PageRank scores are better correlated to human movement rates than the space syntax metrics, and (2) the underlying space-space topology demonstrates small world and scale free properties. The findings provide a novel justification as to why space syntax, or topological analysis in general, can be used to predict human movement. We further conjecture that this kind of analysis is no more than predicting a drunkard's walking on a small world and scale free network.
