“…Choice, instead, defined as the frequency of a spatial element on the shortest paths connecting all pairs of other elements, and hence the equivalent of betweenness in graph theory [23], is suitable for measuring how likely a spatial element is to be passed through. In fact, several studies attest to a strong correlation of choice with the distribution of movement flows [12,25,26]. In other words, while integration reproduces the to-movement potential of a spatial element as a destination, choice measures the through-movement potential of an element as a part of a route [1,27].…”

Abstract:The recent urban growth of Florence was mainly oriented northward, thus determining the urbanization of the flatland and the inclusion within a unique conurbation of a number of pre-existing urban nuclei. Over time, the congestion of the inner core has caused more and more prominent activities to shift towards this developing area, which is today one of the most attractive parts of the whole settlement, counterbalancing the representativeness and the touristic attractiveness of the historic center of Florence. This paper is concerned with the use of space syntax in order to reconstruct the genesis of the configurational geography of Florence. Configurational values at different dates will be cross-referenced with vehicular traffic data, so as to pinpoint the actual inclusion of the motorway A1, touching Florence on its western side, within the urban grid of Florence and its influence in the distribution of local traffic flows. Aside from this case study, this method can be extended to the general issue of the management of motorways in metropolitan areas. More in general, this approach is proposed as a suitable tool for interconnecting spatial issues and traffic questions, so as to concur in bridging the gap between urban design, focused on the morphologic features of blocks and buildings, and transport analysis, strictly concerned with the distribution of movement flows on the street network.

“…Segment Angular Analysis -The study area is formed as a street network into a segment map (Hillier et al 2007). The analysis reveals patterns of line connectivity that is called integration 8 , which can be the global or local measurement that extrapolates an average on all other lines within the whole configuration (Penn et al 1998). The study uses segment analysis, which utilises the axial map to convert each line into segments between each street (Turner 2008), measuring the segment angular integration and choice in the urban street network.…”

IntroductionThis paper explores how choices made about land use are related to the configurationnal logic of space. Configurative analysis is a complex technique that explores space based on the urban grid as the fundamental generator of movement and locator of activities. The distribution of activities that people adapt and transform is produced by the choices of actions. These actions involve decision-making processes that also reflect a process of urbanity. Urbanity comes from the notion of city form and its activity, street life and urban culture. It forms as a result of urban design, which supports and organises urban life as a 'socio-spatial category of urban form ' (Marcus 2007: 3). Decision-making, in this case, refers to the outcome taken from a rational selection of alternatives that leads to a specific course of action, resulting in a final choice. Urban planning can generate strategies that serve for future urbanisation, yet the temporality of space is an important part of how different places are generated. Aldo Rossi (1982) argues that the mutations, transformations or even small alterations in a city take different lengths of Urban forms emerge from the interplay of social, economic, political and cultural forces, which are partly attributed to decision-making processes of urban planning and design. However, decision-making involves the everyday life of using and navigating in the built environment to the management of urban space. This paper seeks to understand the basic notion of how pedestrian movement is related to land use choices in the built form. The hypothesis is that movement itself involves a choice; that is, a decision-making of direction and destination, of passing through or of static behaviour. The density of movement flow is seen as a result of locations that potentially become attractors that have a rich distribution of land use. How we accommodate and modulate movement is thus important in helping us understand the multiple effects of everyday use that arises from decision-making processes and its subsequent effectuation in the configuration of urban space. Therefore, two key questions are addressed: first, how the types of movement choices influence and are influenced by the spatial layout; and second, how the distribution of land uses is affected by such choices. The paper uses Space Syntax and Game theory as a combination of theoretical frameworks that study independent and interdependent decision-making processes in urban space, to answer these questions. Taking the River Thames Path as an example, the research project focuses on the unconnected section of the river walk between London Bridge and Southwark Bridge. In analogy with a game of chess, the results demonstrate how different kinds of choices are ruled primarily by the location of commercial uses in the urban grid. MDCCCXXVI OPTICON

Pedestrian-oriented transportation has recently emerged as an important issue to supplement transportation modes as a method to reduce traffic accidents and environmental pollution. Compared to the increasing attention, practical studies considering the transportation environment in Korea are very limited. As a first step for studying the service level of pedestrian environment, it is necessary to develop an objective and systematic evaluation scheme. This paper aims to develop the 'Green Score', an evaluation system, which can be used to compute and evaluate the service level of pedestrian environment. In this study, we focused on pedestrian axes associated with vehicle crosses for the evaluation. We applied the depth-based index used in space syntax theory in assessing the space structure in terms of the connectivity. For setting the weight values of evaluation criteria obtained from survey, we employed AHP (Analytic Hierarchy Process). The computed scores using these criteria are classified and normalized according to the levels of pedestrian dependency and, finally, displayed on a map. The proposed Green Score system is expected to be applicable in the visualization of pedestrian movements and the evaluation of convenience levels of pedestrian environment.
