Paper Three: Urban Modelling - An Architectural Review
This section paves the ground for developing a design approach based on the concept of Emergence to tackle issues relating to the built environment, by reviewing some of the existing techniques and approaches to urban modelling. This is by no means extensive but only aims to open up debates on how urban development can be conceived, designed and implemented on the basis of algorithmic definitions which could embed effective strategies to tackle design issues of sustainability.
URBAN MODELS FROM THE DISTANT PAST
The Legal News, 2020
Many of us have plunged into the polymathic whirlpool of ideas and reflections. Our pursuit reflects the goal of developing a human world of sufficient affluence for all within a sustainable economy. Radiating ideas within a circle of thought unite as a whole to reflect this goal. We find ourselves in a spot where we need to define the central whorl (a convex hull) along our journey. We can call this our Imagineering Project of Social Development, the Monocentric City concept, which has a central seat of government surrounded by expanding residential and commercial subcenters.
Town Planning Review, 2007
The term 'model' is now central to our thinking about how we understand and design cities. We suggest a variety of ways in which we use 'models', linking these ideas to Abercrombie's exposition of Town and Country Planning which represented the state of the art fifty years ago. Here we focus on using models as physical representations of the city, tracing the development of symbolic models where the focus is on simulating how function generates form, to iconic models where the focus is on representing the geometry of form in both two and three dimensions. Our quest is to show how digital representation enables us to merge and manipulate form into function and vice versa, linking traditional architectural representation to patterns of land use and movement. Mathematics holds the key to simulation of many kinds and computers now enable us to move effortlessly from the material world of atoms to the ethereal world of bits and back. These new tools also provide us with powerful ways of showing how the real is able to morph into the ideal and vice versa. We argue that this digital world which parallels the material, now gives us unprecedented power to understand and explore cities in ways that Abercrombie could only speculate upon, and we conclude by anticipating how we might respond to the new challenges posed by unlimited access to these virtual worlds.
Handbook of Research on Geographic Information Systems Applications and Advancements
Modelling and simulating cities evolution has been lately the focus of scientific studies, in the urban field, as it represents a mean for effectively managing and planning land-development. Consequently, the development of urban models has known a remarkable growth. This model boom was a key driver behind many studies aiming at providing comprehensive reviews of existing urban models through classifying them based on various characteristics. In this context, this chapter reviews the different classification studies, proposes a classification of a set of most popular models based on their modelling-task, strategy, and data, then assume and argue how these three elements can majorly affect the modelling-approach choice-making. Indeed, its overall goal is to deliver a sort of "white paper" aiming at assisting researchers in their seeking for the most adequate modelling-approach for their urban modelling-task specifications.
Parsimonious Models of Urban Space
2007
This paper sets out an approach to urban modelling derived from early work with cellular automata and agglomeration models. In these cases the models are an example of distributed representation, where the rules built in to the model are replicated in all the discrete components of the model be they cells or agents. This is the classic AI. / AL paradigm of emergent systems. The paper describes the main structure of the models, and presents examples of the use of this modelling process in design education, pointing out the way dynamic models allow mapping on to interesting speculations about the dynamic of the city, and its social systems. The paper ends with a report on the use of such models as a design decision support system and how they will be used in planned work in master planning in the London Thames gateway area under the UK govt. sustainable communities initiative.
Issues of Abstraction, Accuracy and Realism in Large Scale Computer Urban Models
CAAD futures 1997, 1997
The availability of large scale computer urban models promises to radically improve the effectiveness of urban design policy-making and development control. A key question in the implementation of such models is how the balance between abstraction, accuracy and realism influences the effectiveness of their use. This paper discusses and illustrates the issues involved, with a computer model of the City of Adelaide as example.
The 3D-city model: a new space
2001
We have worked with the construction and use of 3D city models for about ten years. This work has given us valuable experience concerning model methodology. In addition to this collection of knowledge, our perception of the concept of city models has changed radically. In order to explain this shift in paradigms we begin by describing some of the concrete models we have made, showing the relationship between model structure (methodology and content) and model use. We also describe the projects we are working on at present in order to illustrate new ideas concerning the potential development of 3D city models
