title Road hierarchy and speed limits in Brasília/Brazil

summary This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

title Spatial Configuration and Sociaty. Comparison between the street market Tristan Matta and Tirso de Molina Market
source SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 2 - ISBN: 978-85-8039-133-6] Florianópolis, SC, Brasil 23-27 November 2015, pp. 481-485.
summary This research aims to clarify how certain visual and accessibility patterns, in buildings and urban environments, are related to social activities that take place in them. The study, based on the theory of space syntax (Hillier & Hanson 1984; Hillier, 1996), seeks to recognize patterns of behavior, both individual and aggregate. The case studies are Tirso de Molina Market and the free street market Tristan Matta, both in Santiago de Chile.

title Image and Shape: Two Distinct Approaches
source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 410-415
summary This paper is the result of two researches done at the district of Campeche, Florianópolis, by the Grupo PET/ARQ/UFSC/CAPES. Different aspects and conceptual approaches were used to study the spatial attributes of this district located in the Southern part of Santa Catarina Island. The readings and analysis of two researches were based on graphic pistures builded with the use of Corel 7.0 e AutoCadR14. The first research – "Urban Development in the Island of Santa Catarina: Public Space Study"- examined the urban structures of Campeche based on the Spatial Syntax Theory developed by Hillier and Hanson (1984) that relates form and social appropriation of public spaces. The second research – "Topoceptive Characterisation of Campeche: The Image of a Locality in Expansion in the Island of Santa Catarina" -, based on the methodology developed by Kohlsdorf (1996) and also on the visual analysis proposed by Lynch (1960), identified characteristics of this locality with the specific goal of selecting attributes that contributed to the ideas of the place its population held. The paper consists of an initial exercise of linking these two methods in order to test the complementarity of their analytical tools. Exemplifying the analytical procedures undertaken in the two approaches, the readings done - global (of the locality as a whole) and partial (from parts of the settlement) - are presented and compared.

title Awareness Space in Distributed Social Networks
source Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 615-628
summary In the real work environment we are constantly aware of the presence and activity of others. We know when people are away from their desks, whether they are doing concentrated work, or whether they are available for interaction. We use this peripheral awareness of others to guide our interactions and social behaviour. However, when teams of workers are spatially separated we lose 'awareness' information and this severely inhibits interaction and information flow. The Theatre of Work (TOWER) aims to develop a virtual space to help create a sense of social awareness and presence to support distributed working. Presence, status and activity of other people are made visible in the theatre of work and allow one to build peripheral awareness of the current activity patterns of those who we do not share space with in reality. TOWER is developing a construction set to augment the workplace with synchronous as well as asynchronous awareness. Current, synchronous activity patterns and statuses are played out in a 3D virtual space through the use of symbolic acting. The environment itself however is automatically constructed on the basis of the organisation's information resources and is in effect an information space. Location of the symbolic actor in the environment can therefore represent the focus of that person's current activity. The environment itself evolves to reflect historic patterns of information use and exchange, and becomes an asynchronous representation of the past history of the organisation. A module that records specific episodes from the synchronous event cycle as a Docudrama forms an asynchronous information resource to give a history of team work and decision taking. The TOWER environment is displayed using a number of screen based and ambient display devices. Current status and activity events are supplied to the system using a range of sensors both in the real environment and in the information systems. The methodology has been established as a two-stage process. The 3D spatial environment will be automatically constructed or generated from some aspect of the pre-existing organisational structure or its information resources or usage patterns. The methodology must be extended to provide means for that structure to grow and evolve in the light of patterns of actual user behaviour in the TOWER space. We have developed a generative algorithm that uses a cell aggregation process to transcribe the information space into a 3d space. In stage 2 that space was analysed using space syntax methods (Hillier & Hanson, 1984; Hillier 1996) to allow the properties of permeability and intelligibility to be measured, and then these fed back into the generative algorithm. Finally, these same measures have been used to evaluate the spatialised behaviour that users of the TOWER space show, and will used to feed this back into the evolution of the space. The stage of transcription from information structure to 3d space through a generative algorithm is critical since it is this stage that allows neighbourhood relations to be created that are not present in the original information structure. It is these relations that could be expected to help increase social density.

title Space-Use Interactions Described Through Computer Vision
source Stouffs, Rudi and Sariyildiz, Sevil (eds.), Computation and Performance – Proceedings of the 31st eCAADe Conference – Volume 1, Faculty of Architecture, Delft University of Technology, Delft, The Netherlands, 18-20 September 2013, pp. 403-412
summary This paper examines analytical procedures aimed at the study of the functional condition of architectural artefacts and, as a result, the promotion of a better understanding of the connections established with spatial conditions. The goal is to contribute to the development of techniques based on computer vision of mobility and users’ interaction, producing non-arbitrary registries of their movement/navigation and occupancy/co-presence patterns via a quantitatively based analysis.Movement/navigation and occupancy/co-presence patterns were correlated with configurational properties obtained by applying the space syntax descriptive model (Hillier and Hanson, 1984). It was possible to analyse relations between the spatial configuration and the movement/navigation and occupancy/co-presence patterns, a key question within the architectural conceptual process.

title Visual and Spatial Analysis in Office Design
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The demands for rapid response to complex problems, flexibility, and other characteristics of today's workplace, such as a highly trained work force, have led many organizations to move from strict hierarchical structures to a more flexible project team organization. The organizational structure is broader and flatter, with greater independence given to organizational units, in this case the project teams. To understand the relationship between project team communication patterns and the design and layout of team space, a study was conducted of an architectural office before and after a move to new space. The study involved three project teams. Information was collected on individual communication patterns; perceptions of the ease of communication; and the effectiveness of the design and layout of physical space to support these communications. In order to provide guidance for critical decision-making in design, these communication data were correlated with a series of measures for the specification of team space enclosure and layout. These group/team space measures were adaptations of existing measures of individual work space, and included an enclosure measure, based on an enclosure measure developed by Stokols (1990); a measure of visual field, based on the "isovist" fields of Benedikt (1979); and an "integration" measure, based on the work of Hillier and Hanson (1984). Results indicate both linear and non-linear relationships between interaction patterns and physical space measures. This work is the initial stage of a research program to define a set of specific physical measures to guide the design of supportive work space for project teams and work groups within various types of organizations.

title Building a Synthetic Cognizer
source Design Computation Cognition conference 2004, MIT
summary Understanding ‘space’ as a structured and dynamic system can provide us with insight into the central concept in the architectural discourse that so far has proven to withstand theoretical framing (McLuhan 1964). The basis for this theoretical assumption is that space is not a void left by solid matter but instead an emergent quality of action and interaction between individuals and groups with a physical environment (Hillier 1996). In this way it can be described as a parallel distributed system, a self-organising entity. Extrapolating from Luhmann’s theory of social systems (Luhmann 1984), a spatial system is autonomous from its progenitors, people, but remains intangible to a human observer due to its abstract nature and therefore has to be analysed by computed entities, synthetic cognisers, with the capacity to perceive. This poster shows an attempt to use another complex system, a distributed connected algorithm based on Kohonen’s self-organising feature maps – SOM (Kohonen 1997), as a “perceptual aid” for creating geometric mappings of these spatial systems that will shed light on our understanding of space by not representing space through our usual mechanics but by constructing artificial spatial cognisers with abilities to make spatial representations of their own. This allows us to be shown novel representations that can help us to see new differences and similarities in spatial configurations.

title Generative sub-division morphogenesis with Cellular Automata and Agent-Based Modelling
source RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.166-174
summary This paper reports on some recent research carried out to develop computational generative urban design system that can be used as an alternative approach to master planning. The focus of the investigation is an 11 ha site located in the South-East edge of Auckland, New Zealand. The urban (or sub-urban) morphology is modelled as cellular automaton based on Hillier’s (1984) x-y syntax in order to resemble the morphology of the existing village. An agent based system based on Reynolds’ (1987) flocking algorithm evolves synchronously with the automaton and tests its ecological fitness. The emergent pattern of development therefore results from the mutual co-adaption of the cellular automaton and the agent based model. The outcomes are variety of spatial morphologies that connects well with adjacent existing village and at the same time take into account landscape and ecological peculiarities of the site.
