title	Road hierarchy and speed limits in Brasília/Brazil
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
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	Development of a Simple Web-based GIS System for Sustainable Housing Projects VisualizatioN
source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 236-243

summary	This paper presents a simple web-based GIS system for visualization of Baan Mankong, as known as sustainable housing projects for communities of low-incomers in Thailand. The Baan Mankong project has been so successful that numbers of projects initialized have been increasing during the past couple of years. The projects information is gathered in a huge database, but there is a lack of visualization tool to help the officers and executives to have a global view of the projects’ spatial distribution and to have a quick access to project information. GIS is proposed as a tool to be developed on the web for the visualization of this project. The Baan Mankong’s work flow and project information are studied in order to select only necessary information to be stored in the system. Then, the geographic visualization tool development process is presented.

title	Brand Value of Area-Images Extracted from SpatialDistribution of Building Names
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	Our area-images are composed of evaluations derived from the various kinds of elements or activities within different regions. In quantitative terms, the extraction of area-images is difficult. In this paper, we focus on a phenomenon in which a part of people’s area-image can be observed in the names of buildings. In the first instance, a model based on the random utility theory is constructed to describe the spatial distribution of building names. Secondly, the proposed model is calibrated using actual data from the city of Tokyo (Setagaya Ward), and effects of such area-elements or activities on area-images are then estimated. Finally, values for the area-images are quantitatively estimated and their spatial distribution is represented on a map.
