title Simulation of Micro Pedestrian Behaviour in Shopping Streets
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Progress in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN-10: 90-386-1756-9, ISBN-13: 978-90-386-1756-5, p. 101-116
summary Over the years, scholars have developed various models of pedestrian movement. These models can be used to assess the effects of detailed design decisions or to predict pedestrian behaviour under conditions of crowding. To date, not much attention has been paid to pedestrians' shopping behaviour at the micro level. Therefore, the main purpose of this project is to test a model that aims at simulating micro pedestrian behaviour in shopping streets, including entering shops. The model assumes a detailed network of links to represent the structure of street segments and entrances to the shops. The basic principle underlying the model is that a pedestrian moves from one link in the network to another, adjacent link. In fact, a pedestrian enters a segment at one side, heading for the other side of the segment. However, a pedestrian might enter the segment by leaving a shop as well. Then, the pedestrian might be heading for either side of the segment. While transferring from the current link to the next link, the pedestrian will be attracted by the shops along both sides of the street. The study area is Antwerp's main shopping street. During a one-week workshop in July 2004, students observed pedestrian movement in this shopping street. An inventory of some physical characteristics of the shopping street was made and pedestrians were tracked through two separate segments of the shopping street. In total, 334 pedestrians were tracked. A conventional multinomial logit model is used to simulate pedestrians' micro behaviour. The process of consecutively selecting links continues until the pedestrian has reached one of the terminal links or a shop. The model performs very well. Simulated routes were used to assess the validity of the model. Observed and simulated link loading correspond fairly well, however, the model seems to slightly mispredict the attraction of a number of shops.

summary The choice of a chord and its execution should be regarded as a must and not left to arbitrary wish or superficial speculation. (Johannes Itten, 1961) The paper describes a modular concept for the IT-support of planning practice using BIM (Building Information Modelling) and a parameterized building model. The platform used is the modularized software concept for architectural planning in existing built contexts (prototype software FREAK). The current progress in the development of a reasoned support of planning tasks is described in this paper in more detail. The system consists of a series of software prototypes which are linked to the BIM, utilize the specific data within and demonstrate the value of a consistent and extendable CAD-model. The “Colored Architecture” software prototype is one such design-support module of the software platform and enables the designer to experiment with the parameters colour, light and materials in architectural space. This module supports experimentation, assessment and realization of colours and materials in the architectural design process on a new quality. For instance, the integration of “live radiosity” light simulation allows a qualified and interactive assessment and evaluation of colours and materials in near-real lighting conditions. The paper also details further software prototypes, modules and concepts including building surveying and the design of self-supporting domed structures.

title Can Decision Making Processes Benefit from a User Friendly Land Use and Transport Interaction Model?

summary Urban regions today face serious challenges caused by past and ongoing transport and land use developments. Decision making in this context is a challenging task which was explored in detail in a series of research projects. To support decision making, tools were developed to reduce the risk of inappropriate decisions in the land use and transport context. One of these tools is MARS (Metropolitan Activity Relocation Simulator); an integrated dynamic land use and transport model. The paper presented here focuses therefore on two main issues: 1) the introduction of the decision support tool MARS and of the cause-effect relations between the land-use and the transport system implemented within MARS; and 2) the design and application of the MARS flight simulator (MARS FS) as a graphical user interface for MARS especially designed to the needs of decision makers.

title Teaching parametric design in code and construction
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 158-161
summary Automated manufacturing processes with the ability to translate digital models into physical form promise both an increase in the complexity of what can be built, and through rapid prototyping, a possibility to experiment easily with tangible examples of the evolving design. The increasing literacy of designers in computer languages, on the other hand, offers a new range of techniques through which the models themselves might be generated. This paper reviews the results of an integrated parametric modelling and digital manufacturing workshop combining participants with a background in computer programming with those with a background in fabrication. Its aim was both to encourage collaboration in a domain that overlaps both backgrounds, as well as to explore the ways in which the two working methods naturally extend the boundaries of traditional parametric design. The types of projects chosen by the students, the working methods adopted and progress made will be discussed in light of future educational possibilities, and of the future direction of parametric tools themselves. Where standard CAD constructs isolated geometric primitives, parametric models allow the user to set up a hierarchy of relationships, deferring such details as specific dimension and sometimes quantity to a later point. Usually these are captured by a geometric schema. Many such relationships in real design however, can not be defined in terms of geometry alone. Logical operations, environmental effects such as lighting and air flow, the behaviour of people and the dynamic behaviour of materials are all essential design parameters that require other methods of definition, including the algorithm. It has been our position that the skills of the programmer are necessary in the future of design. Bentley’s Generative Components software was used as the primary vehicle for the workshop design projects. Built within the familiar Microstation framework, it enables the construction of a parametric model at a range of different interfaces, from purely graphic through to entirely code based, thus allowing the manipulation of such non-geometric, algorithmic relationships as described above. Two-dimensional laser cutting was the primary fabrication method, allowing for rapid manufacturing, and in some cases iterative physical testing. The two technologies have led in the workshop to working methods that extend the geometric schema: the first, by forcing an explicit understanding of design as procedural, and the second by encouraging physical experimentation and optimisation. The resulting projects have tended to focus on responsiveness to conditions either coded or incorporated into experimental loop. Examples will be discussed. While programming languages and geometry are universal in intent, their constraints on the design process were still notable. The default data structures of computer languages (in particular the rectangular array) replace one schema limitation with another. The indexing of data in this way is conceptually hard-wired into much of our thinking both in CAD and in code. Thankfully this can be overcome with a bit of programming, but the number of projects which have required this suggests that more intuitive, or spatial methods of data access might be developed in the future.

title User needs at the heart of town: Orientation and appraisal in an endoscopic city scale model (script)
source Motion, E-Motion and Urban Space [Proceedings of the 7th European Architectural Endoscopy Association Conference / ISBN-10: 3-00-019070-8 - ISBN-13: 978-3-00-019070-4], pp. 115-131
summary In this paper we provide a “work-in-progress” report on on going investigation into the perception of building alternatives at a central urban place. The city-planning task in this case involves the development of several key parcels of real estate, with significant impact on a mediumsized German city’s overall appearance and functionality. The interests of investors wishing to maximize economic utilization are competing with public interests regarding urban planning and urban design as well as development needs. Hence, there is a need for the development of different spatial layouts for the district to help identify reasonable concepts for the use of these key properties and their impact on the visual townscape as well as the functional spatial properties of the city’s open space. Ultimately, clear deed restrictions and guidelines are to be identified for future investors to preserve the cityscape and to improve the quality of the existing public open space but also to enhance downtown’s existing sensible economic equilibrium.

title Integration of Virtual Reality within the Built Environment Curriculum
source ITCon Vol.11 pp. 311-324
summary Virtual Reality (VR) technology is still perceived by many as being inaccessible and cost prohibitive with VR applications considered expensive to develop as well as challenging to operate. This paper reflects on current developments in VR technologies and describes an approach adopted for its phased integration into the academic curriculum of built environment students. The process and end results of implementing the integration are discussed and the paper illustrates the challenges of introducing VR, including the acceptance of the technology by academic staff and students, interest from industry, and issues pertaining to model development. It sets out to show that fairly sophisticated VR models can now be created by non-VR specialists using commercially available software and advocates that the implementation of VR will increase alongside industry’s adoption of these tools and the emergence of a new generation of students with VR skills. The study shows that current VR technologies, if integrated appropriately within built environment academic programmes, demonstrate clear promise to provide a foundation for more widespread collaborative working environments.

title Developing a Spatial Context-Aware Building Model and System to Construct a Virtual Place
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Progress in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN-10: 90-386-1756-9, ISBN-13: 978-90-386-1756-5, p. 343-358
summary The current notion of space seems to be inappropriate to deal with contemporary and future CAAD applications because it lacks of user and social values. Instead of using a general term called 'space', our approach is to consider the common unit in architectural design process as a place composed of space, user and activity information. Our research focuses on developing a novel intelligent building data model carrying the essence of place. Through our research, the needs of using virtual architectural models among various architectural applications are investigated at first step. Second, key characteristics of spatial information are summarized and systematically classified. The third step is to construct a semantically-rich building data model based on structured floor plan and the semantic location modeling. Then intermediate functions are created providing an interface between the model and future applications. Finally, a prototype system, PlaceMaker, is developed to demonstrate how to apply our building data model to construct virtual architectural models embodying the essences of place.

title A Multi-Agent Model for Generating Local Land-Use Plans in the Context of an Urban Planning Support System
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Progress in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN-10: 90-386-1756-9, ISBN-13: 978-90-386-1756-5, p. 153-168
summary In a multi-player urban planning process, the outcome of any individual decision of the actors is uncertain until a state where the plan is satisfactory for all. To support the plan generation phase, this paper develops a generic multi-agent system, in which agents represent particular land-uses. In the system, agents higher in the hierarchy have priority over agents lower in the hierarchy to claim units of land. This one-direction claim process may result in a plan that is not optimal for every agent. The system, therefore, allows agents to revise their plans in an iterative procedure. A case study illustrates centralized, semi-centralized and decentralized solutions for a plan area based on the outcomes of different strategies used by facility agents (retail, green, schools) and a housing agent. The results show that the proposed system is able to generate rational and realistic plan alternatives for new residential areas.

title An Internet Survey for an Activity-Based Model - An urban transportation analysis integrated in a G.I.S. environment

summary The current research deals with the development of an Activity-Based Multi Agent System fully implemented in a G.I.S. framework and applied to the case study of the historical centre of Pisa. The objective is to create a simulation tool for Pisa population transfers in order to verify how transport demand varies because of interventions on traffic plan (e.g. creating urban areas subject to a toll access for vehicles), or on public transport lines, or on new activities location (e.g. supermarkets, public services etc.). Three different parts of the System have been simultaneously carried out: the first concerns a population sample survey, the second deals with geographical data structuring and the last one, still in elaboration progress, tests the model reliability to estract and implement behavioural rules. The results obtained till now show how the Database itself, containing temporal data about agents activities (extracted by the population sample questionnaire) and urban services the city offers, already represents an important instrument to support decision making process.

summary This paper describes a pilot test conducted as part of the ongoing research project. The performed pilot test describes the collaborative knowledge construction under two conditions: i) Collaborative knowledge construction in a traditional brainstorm setting ii) Collaborative knowledge construction in a proposed method (section number) described further in the paper. The pilot test focuses on measuring the shared mental model of a multi-disciplinary design team involved in a problem solving session. The approach to the study to predict shared understanding was to measure overlapping of mental models on a set of concept construct pairs of individuals during the design session. The findings of the pilot test were that the shared understanding in the proposed condition was better compared to the traditional means of brain storming.

summary People only move a limited number of times during their lifetime. Factors such as high financial costs, local social networks, emotional bounds, etc. make that people typically postpone this decision as long as possible, up to the point where the benefit of alternative housing outperforms all these factors. Then things generally have to go fast. This combination of time-pressure, high costs and lack in experience turn residential search and location choice into a complex decision process. This paper presents a model developed to grasp some of this complexity. Households are approached as autonomous decision-makers continuously evaluating whether to search for information, to visit houses for inspection, to start negotiating with the owner of a house for sale or to do nothing and stay in the current house. Households make these evaluations on the basis of beliefs regarding their environment and update these beliefs each time they collect new information on this environment.

summary To make our cities sustainable is one of today's major challenges. The complexity of this task requires suitable planning tools. The aim of this paper is to present a hierarchical modelling approach to assess the effects of transport and land use projects and instruments. First a brief definition of the overall objective sustainability is given. This is followed by the description of the suggested hierarchical approach. A strategic, dynamic land use and transport interaction model builds the basis and is linked to models on a different spatial and functional level. A case study covering the Spanish region of Madrid ('Comunidad de Madrid') was selected to demonstrate the applicability. In particular the effects of the public transport infrastructure projects, the extension of the metro line number 9 and bus lanes on all radial highways, should be assessed. It is demonstrated that the suggested approach is applicable and suitable. The overall effect of the metro line extension and the bus lanes is positive. Nevertheless their contribution to a sustainable urban region is limited. Comprehensive strategies are needed to achieve the objective of sustainability. It could be shown that the projects can even have some negative local effects in the long term.

summary This paper describes a conceptual framework for modeling activity interactions between household heads in conducting out-of-home maintenance activities. It is comprised of several steps; generation of household activities, task allocation of household activities, trip-chaining choices, resource allocation and mode choice. The models are specified for different household types: worker and non-worker households, with or without children. The purpose of this paper is to introduce the modeling framework for household travel activity decision making processes so that it can capture interactions between household heads.

title Developing a Virtual Test-Bed to Design Human-Centered Ubiquitous Space

summary Future space is currently getting a great deal of attention to apply ubiquitous computing technology. To design these spaces, the need to make a physical test-bed, a real building model, is essential for human-centered design. However building a physical test-bed generally is economically expensive and even if the test-bed could be settled, it must be carefully designed before it is built. In this paper, we suggest a virtual smart test-bed, called 'V-PlaceLab'. This system allows not only to research a human behavior with the aid of computer simulation on a virtual environment, but also to design a human-centered ubiquitous space mentioned above.

summary In the Architecture Engineering and Construction (AEC) sector, cooperation between actors is essential for projects success. During the building construction activity, organization is both hierarchical and adhocratic. Decision assistance tools have to integrate these heterogeneous parameters. The proposition described here consists of the design of a coordination assistance tool providing synthetic indicators on the statement of the activity and also allowing the user to navigate in the cooperative context through multiple views. This proposition is based on a model architecture allowing us to manage cooperative context information and its visualization.

summary In the process of architecture design, the manufacture of study model acts a procedure of swift transformation from concept to a visible model. Since the era of CAD/CAM approaches, the tool of constructing the model evolves from the traditional physical model to digital model in the mode of the manufacture of study model. The virtual model, which is utilized in the incipient concept discussion by the designer, has become a new intermediary material. However, the virtual model or physical model respectively acts its role that may not be substituted now. TUIS (Tangible User Interfaces) is the intuitional interface system of discussion on striding these two intermediary materials. By the information interchange between the physical model and virtual model, a designer can dedicate to the procedure of design development rather than be restricted to the operation and usage of these interfaces. However, there are many problems existing in applying such a system to the solid geometry model stack. This essay will discuss that a designer explores the incipient design application by manipulating physical model and virtual model.

A digital design by ambience intention framework is proposed, allowing intention expression of daylighting ambience through scene lighting properties. Lighting descriptors are introduced to represent theses properties, and combined to produce a lighting constraint set. These constraints are intended to be used in an inverse lighting model to compute geometrical raw solutions.

title Development of 3D Tactile Models for the Partially Sighted to Facilitate Spatial Orientation
source Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 366-370
summary Lacking or poor provision of comprehensive information about the spatial environment for the purposes of effective orientation is a problem that primarily affects the blind and partially sighted, but it can also cause difficulties for older people with increasing visual impairment. This research project in progress aims to obtain new scientific findings with regard to the basic suitability and required composition of tactile models to facilitate spatial orientation for the blind and partially sighted. Tactile scale models serve as an orientation aid. Their intention is to make it easier for visually impaired people to “experience” selected structural characteristics of the real space, even if in scaled-down form. This experience allows them to experiment with space and to better recognize spatial elements and their interrelationships. It also helps them to better recognize subspaces, possible spatial sequences, as well as decision-making situations in these spaces. These tactile processes are supported by the highly sensitive tactile faculties of people with visual impairment, which are far more finely differentiated than those of sighted people who experience objects without this disability. The amount of available digital model data is constantly growing and would allow for the creation of tactile models.

summary Today's industrials are facing numerous product development challenges and pressures as a result of an increasingly competitive market. It creates an enormous need for a constantly growing supply of new ideas and solutions. The computer support used by designers still lacks the ability to use experiential knowledge in a rational way. Therefore, pursuit of designer is utilizing innovative design methods and problem-solving approaches to systematically simplify design problem, and hence accelerate the design process. This paper proposed to integrate TRIZ method into CBR process and aims at exploring the possibility to use TRIZ method as a complement to enhance performance of CBR in product design. Wall lighting design problem is used as example, and an interactive CBR system is not only built to provide designers a computational tool to efficiently retrieve usefulness design cases but also assist designers systematically in finding creative ideas.
