Economical influence and competition into urban area. Measuring test
1986
Définition et propriétés générales de l'indicateur d'influence effective, illustration sur un exemple numérique (agglomération découpée en six zones). Résultats d'une application au cas de l'agglomération dijonnaise (découpage en 20 quartiers; les douze communes périphériques sont retenues dans l'application). On relie onze fonctions de biens et de services: alimentation; équipement de la personne, équipement de la maison; autres commerces spécialisés; pharmacie, optique, orthopédie; services médicaux; services paramédicaux; bureaux de poste; banques et établissements financiers; éducation secondaire spécialisée; hôtellerie. Test de plusieurs simulations relatives à diverses répartitions de…
Modeling urban growth by cellular automata
1996
International audience; The structural development of human settlements can be characterized as a complex highly feedbacketed process. The assumption that this process is governed by rather few fundamental laws stimulated a considerable research in the field of urban growth during the last decade. Aiming at the comprehension of the basic underlying dynamics different approaches from the field of self-organizing systems have been proposed. In this paper we present a "cellular model" of urban growth dynamics based on the work of White, Engelen and Uljee. As a starting point this model throws some light on the mechanism of urban growth. But even more important, it raises a lot of questions con…

Urban dynamics, mobilities and transport in the Algerian Southwest (wilayas of Adrar and Bechar)
2012
Between a regional perspective of the territorial (spatial) planning and a geopolitical vision of the region " Sahel, the Maghreb ", the Algerian State made a commitment since the second decade of its independence not only to develop transport in the Saharan zones but also to set up the necessary equipments for the economical and social development of these zones, by serving almost the totality of the urban areas. In the Southwest, this dynamics remodelled profoundly the relational space in Saoura, Gourara and Touat.Structured formerly by the roads of the trans-Saharan caravan business, this space opens up, attributes new functions and becomes urbanized. A new reorganization of the space is…

On the emergence of the urban phenomenon Part II
2001
In this paper, we extend the basic model describing the formation of urban agglomerations in a pre-industrial setting. As we will show, this setting is flexible enough to allow for the investigation of multiple aspects of the spatial economy. After summarizing the basic model and the numerical examples we will refer to, we successively examine the issues of coordination failure in the emergence of the urban phenomenon, the presence of transactions costs and the possibility of diffusion of manufactured good production through the system of agglomerations. This last aspect will be treated in two different ways : that of increasing agricultural productivity and that of increasing technologi…
