city planning regional planning modeling |
| Résumé : |
Cities and regions are highly complex but ordered systems. They are thus best understood by modelling within the framework of the theory of complex, self-organizing systems. This theory suggests that fractal structure is a signature of self-organized systems, and that systems that are far from thermodynamic equilibrium have open futures. These two phenomena have important consequences for the calibration and validation of realistic models, with the open futures phenomenon raising fundamental methodological issues that are addressed in the book. The models themselves are cellular automata (CA) based, because CA are inherently spatial, high resolution, and dynamic. The basic model focuses on land use change, using multiple urban land use classes, with the dynamics driven by linked demographic, economic, and natural system models. Subsequently, a zone-based model of the spatial dynamics of population and economic activity is inserted to constrain the CA model regionally. Ultimately, the dynamics of population and economic activity are modelled together with land use in an activity based variable grid CA which captures spatial interaction effects at all scales, not just local, and permits multiple activities on a single cell. These models show how the complex but ordered urban and regional structure emerges; thus they constitute an advance in urban theory. They also provide a platform that planners can use to investigate the likely effectiveness of proposed plans and policies. Applications to a number of cities and regions are discussed, and applications to Flanders, implemented as part of the official planning process, are described in detail. |
