Fractalopolis, the multifractal urban planning model, now published in the journal “Computers, Environment and Urban Systems”

 

A fifteen pages article synthesizes the planning premises that inspired applying the concept to the Grand Besançon agglomeration, thus outlining the second step of applying fractal models for urban and regional purposes.

Fractalopolis allows conceiving development plans on an urban and regional scale, based on five basic principles: a hierarchized polycentric urban development; a development linked to transportation axes; a locally concentrated development of residential areas avoiding diffuse sprawl, the interpenetration of green areas and urban areas across scales; the preservation of an interconnected network of green and natural areas of different size. The article focusses on the formal frame, which allows integrating all at once these five planning principles. The article starts by introducing the theoretical multifractal planning concept and explains then, more deeply, the software simulation tool, which allows applying the model to real world situations. A detailed description of the different modules and the application to the Great Besançon urban area illustrate the stepwise construction of such a planning scenario. I.) Choosing the central places of different hierarchical order as well as their catchment areas. II.) Evaluation of the performance of these areas with respect to the accessibilities to different types of amenities III.) Analysis and calibration of the spatial configuration of residential development according to the purposes of existing master plans.

Deciding Where To LiveAn Interdisciplinary Approach to Residential Choice in its Social Context

 

This book proposes, from a cross-disciplinary perspective, an original reading of current work on residential choice and the decisions associated with it. Geographers, social-psychologists, economists, sociologists, neurologists and linguists have worked together in the context of collective research into evaluation, choice and decision-making in the use of urban and periurban spaces. A synthetic outlook has been constructed from these complimentary scientific references. The book, which is designed as a handbook, also provides the opportunity to set out the different approaches to deal with the models which have been developed in this field.

We have the pleasure to inform you that the new version of Graphab software (version 2.0) is available. This version can be downloaded from https://sourcesup.renater.fr/graphab/

Graphab is a software application for modeling ecological networks using landscape graphs. Graphab 2.0 provides new features:

  • · Grouping patches in meta-patches
  • · Graph clustering by modularity index
  • · Removing patches whose capacity is too low
  • · Circuit theory on the graph : CF metric and distance matrix
  • · Corridors (command line only)

Improvements

  • · Habitat can be defined by several landscape categories
  • · Patch addition is now available in graphical interface
  • · Least cost paths may take into account slope using a DEM
  • · Automatic conversion of metric distance to cost distance

User manual is available in English and in French.

We hope that Graphab 2.0 will be useful for you! For any problems or suggestions, please contact us at This email address is being protected from spambots. You need JavaScript enabled to view it.
