AIM & OBJETCTIVES: This research addresses the problem of developing sustained urban policies for scattered low density territories that we shall call the extensive city. Focused on the revision of urbanity as a multidimensional and density-related urban indicator, this project aims at contributing towards the definition of design and planning tools for the re-urbanization of extensive urban fabrics in the Portuguese urban regions. The objective is to achieve a policy-driven model and tool-box of quantitative-qualitative urban indicators centered on both urbanity and density.
The project’s aim is the achievement of a new instrumental basis (multidimensional and matrix-based model) to plan, program and design the extensive city: 1. The first goal is to build up a framework of urban indicators centered on the concept of urbanity as an essential urban performance dimension; 2. The second goal is to assign urbanity quantitative attributes, making use of basic variables and quantitative primary indicators; 3. The third goal of the project is to provide the model with a parametric design tool which will ease the handling of such a complex matrix of multiple variables and indicators on governance and design practices; 4. The fourth goal is to show the diverse applications of the parametric design tool for the different stages and functions of the planning process under different urban development scenarios.
The objective is to provide evidence, through case studies, best practices and guidance, of the usefulness of measuring urbanity for promoting planning and governance competences when designing and programming urbanization through re-urbanization processes.
KEY RESULTS: The creation of a new instrumental basis foresees a step ahead in terms of current planning methods for a more consistent site-based decision-making: i) At a governance level, the model provides a dual qualitative-quantitative approach to urban form, envisaging an easier dealing with the plurality of urban actors; ii) At a planning level, the model offers a flexible and real-time adjustable instrumental framework which will allow the project to deal with uncertainty and the challenge of programming by providing alternative scenarios; iii) At a design level the model provides a way to deal with discontinuity and fragmentation by enhancing the designer’s awareness on the topological properties of networks through a set of topology based assessment tools.
