title	Public Transport Planning Evaluation Tools and theirData Requirements and Availability
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 describes two different public transport planning evaluation tools that are used to support planning activities in The Netherlands and Brazil. In the paper extra attention is paid to data requirements and availability. The Dutch tool generates so-called Public Transport Potential Maps that present the potential of public transport at the level of 6-digit postal code zones based on area and public transport related characteristics. With the Brazilian tool, existing and new implemented public transport routes can be evaluated. To identify urban features that influence the performance of the public transport system, the tool compares characteristics of the urban spaces with the different typologies of public transport routes. Examples of the use of both tools including data requirement and availability are shown in this paper, stressing the fact that GIS is currently an essential and universal tool for public transportation planning, despite the conditions of the site and the complexity of the model under analysis.

title	Improved Understanding of Urban Sprawl Using Neural Networks
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 14020-2408-8, p. 33-49
summary	It is widely accepted that the spatial pattern of settlements is a crucial factor affecting quality of life and environmental sustainability, but few recent studies have attempted to examine the phenomenon of sprawl by modelling the process rather than adopting a descriptive approach. The issue was partly addressed by models of land use and transportation which were mainly developed in the UK and US in the 1970s and 1980s, but the major advances were made in the area of modelling transportation, while very little was achieved in the area of spatial and temporal land use. Models of land use and transportation are well-established tools, based on explicit, exogenouslyformulated rules within a theoretical framework. The new approaches of artificial intelligence, and in particular, systems involving parallel processing, (Neural Networks, Cellular Automata and Multi-Agent Systems) defined by the expression “Neurocomputing”, allow problems to be approached in the reverse, bottom-up, direction by discovering rules, relationships and scenarios from a database. In this article we examine the hypothesis that territorial micro-transformations occur according to a local logic, i.e. according to use, accessibility, the presence of services and conditions of centrality, periphericity or isolation of each territorial “cell” relative to its surroundings. The prediction capabilities of different architectures of supervised Neural networks are implemented to the south Metropolitan area of Milan at two different temporal thresholds and discussed. Starting from data on land use in 1980 and 1994 and by subdividing the area into square cells on an orthogonal grid, the model produces a spatial and functional map of urbanisation in 2008. An implementation of the SOM (Self Organizing Map) processing to the Data Base allows the typologies of transformation to be identified, i.e. the classes of area which are transformed in the same way and which give rise to territorial morphologies; this is an interesting by-product of the approach.

title	ARCHITECTURE ‘in computro’ - Integrating methods and techniques
doi	https://doi.org/10.52842/conf.ecaade.2008

summary	The presence of both visible and hidden digital resources in daily life is overwhelming and their presence continues to grow exponentially. It is surprising how little the impact of this evolution is questioned, especially in education. Reflecting on past experiences of this subject to learn for the future seems rarely to be done, and the sheer fact that a digital method exists is often seen as sufficient justification for its use. Are these the perceptions of serious misgivings or isolated views that circulate in the educational world and beyond? We would suggest that the eCAADe (Education and Research in Computer Aided Architectural Design in Europe) and its conferences provide the ideal forum to provide answers in this debate. For the first conference in what is to be the next quarter century of the existence of eCAADe, a theme was chosen that could easily include all aspects of this debate: ARCHITECTURE ‘in computro’ , Integrating methods and techniques It seems a bit vulgar to use a dog-Latin phrase ‘in computro’ for such a serious matter but at least it now has a place between ‘in vivo’ and ‘in vitro’. For more than 25 years CAAD has been available, and has been more and more successfully used in research and commercial architectural practice. In education, which by definition should prepare students for the future, the constantly evolving CAAD metaphor is provoking a challenge to cope with the ever expanding scope of related topics. It is not surprising that this has led to differing opinions as to how CAAD should be taught. Questions such as how advanced research results can be incorporated in teaching, or if the Internet is provoking self-education by students, are in striking contrast with the more fundamental issues such as the discussion on analogue versus digital design methods. Is CAAD a part of design teaching or is it its logical successor in a global E-topia? Although the E of education is a prominent factor in the ‘raison d’être’ of the organisation, the papers presented at this conference illustrate that eCAADe is open to all other relevant contributions in the area of computer-aided architectural design. It will be a fortunate coincidence that this exchange of knowledge and opinions on such state-of-the-art subjects, will be hosted by the The Higher Institute of Architectural Sciences, Henry van de Velde, located in the historical buildings of the Royal Academy of Fine Art established since the founding of the academy in 1662.

summary	New information and communication technologies (ICT’s), gain importance and are changing people’s daily lives. With the introduction of new ICT’s, alternatives for face-to-face contacts and physical presence are provided. In that sense, ICT may offer a substitute to physical travel. Other potential relationships between telecommunication and travel are neutrality, complementation or modification. The relationship between ICT and activitytravel patterns has received a substantial amount of attention recently. However, a link with the wider activity patterns of individuals and households and environmental characteristics is missing in existing studies. The spatial and mobility impacts of social networks are not well known either. However, social networks are crucial to an understanding of travel behaviour. The most important part of travel demand for non-work purposes in terms of distance travelled is for socializing with network members. Hence, individuals’ social network characteristics are relevant for their propensity to perform social activities. The study of social networks can provide new insights to understand the generation of social activities and travel involved. In order to increase our understanding of the interrelationships between properties of the built environment, ICT-use, social networks and activity-travel patterns, these links should be the starting point for analysis. This paper presents a data collection instrument that was developed to study these links and the results of an application of the instrument in a survey among a large sample of households in the Eindhoven region, and discusses the implications of the findings for planning support models.

title	Industry Foundation Classes: A Space-Based Model Scheme?
doi	https://doi.org/10.52842/conf.ecaade.2008.117

summary	This paper illustrates our findings concerning space based design methodologies and interoperability issues for today’s Building Information Modeling (BIM) environments. A method is elaborated which enables building designers to perform an automated energy use analysis, based on an Industry Foundation Classes (IFC) model derived from a commercial BIM environment, in this case Autodesk Revit 9.1. A prototype application was built, which evaluates the building model as well as vendor-neutral exchange mechanisms, in accordance with the Flemish Energy Performance Regulation (EPR) standard. Several issues regarding the need for space-based building models are identified and algorithms are developed to overcome possible shortcomings.
