Fractalopolis

This software application is dedicated to the design of multifractal urban or regional development plans that adhere to five planning principles: hierarchical polycentric urban development; transit-oriented development; locally dense residential development; penetration of green areas into built-up areas across several nested scales; preservation of interconnected networks of natural and green areas having various sizes.

Fractalopolis supports both the design of a multifractal plan for an urban region and the assessment of the suitability of developing each part of the region. It helps to define where to create new housing and new facilities according to the five planning principles set out above.

The conceptual bases of Fractalopolis have been set out by Pierre Frankhauser (laboratory ThéMA, Besançon, France) and Cécile Tannier (laboratory Chrono-Environnement, Besançon, France). The computer application has been created by Gilles Vuidel (laboratory ThéMA, Besançon, France), Cécile Tannier, and Pierre Frankhauser.

Fractalopolis has been originally used by Claudia Yamu (University of Groningen, The Netherlands) as part of her PhD thesis at ThéMA.

This research received financial support from France’s ministry for ecology, sustainable development and energy as part of the PREDIT 3 program.
