63 p.Interest in cities is growing again in Europe. Theories of "growth poles" forgotten since the 1960s re-emerge, although in different form, without the idea of building new cities in the desert. Metropolitanisation, although sometimes difficult to grasp empirically, is recognized as a post-fordist phenomena, with a gain of the importance of large cities, linked to the increasing need for size-based agglomeration effect in the global, networked knowledge economy. And European policy makers are once again discussing the need of and the form for new urban policies at European (as witnessed by the above quote), but also at national scale. From the outset, this project has had two, complementary, but not always easily reconcilable orientations: provide a broad overview of the current and future issues relevant to urban development in all of Europe, advance scientifically beyond the established and well-known data and analyses, provide innovative research. As this report was elaborated in parallel to the new State of European Cities report to be published by DG Regio, we also aimed at complementarity with that report, not wanting to repeat the same analyses based on the same data. In this project, we, therefore, worked in three parallel strands. First, all teams went through the current literature to extract the knowledge about trends, perspectives and, most importantly, driving forces for urban development in their thematic fields. Second, each of the teams focused on one or two innovative empirical research questions, generally tapping new data sources. Finally, our scenario team has taken the work of the other teams, and substantially augmented it through additional literature review, aiming at covering an even larger horizon and to provide a complete knowledge base on urban development, necessary for integrated prospective thinking. On this basis the scenarios were developed. The structure of the report reflects these three strands, adding a fourth, new strand, which consists in an assessment of the current national policy visions on urban issues across Europe. Details of all the literature reviews and analyses are presented in the scientific report

Une nouvelle approche de la proximité pour les études de localisation optimale

A new approach of proximity for the analysis of optimal location Proximity is a relative concept and its definition differs from a milieu to another. Commonly, in optimal location studies, “proximity” is defined as the closest facility to a demand point. Then, in general the location-allocation models, such as the p-median, allocate demand in order to minimize the total distance between customers and their closest facility. Here, we propose a relative approach of the concept of “proximity”. In this approach, “proximity” is defined according to the own spatial context of each demand point. It supposes to introduce a different measure of proximity (sort of natural thresholds of distance). We rank the distance between each demand point and facilities in an increasing order. We can then define gaps in the histogram of the distribution of distance. These gaps represent the longest distance acceptable between a consumers and their facility. However, this new approach of the definition of proximity remains not validated.La proximité est un concept relatif et très variable d'un milieu géographique à un autre. En règle générale, la définition de la proximité retenue dans les études de localisation optimale est celle du site d'offre le plus proche. Ainsi, les modèles de localisation-affectation, tels que celui de la p-médiane, allouent, en règle générale, la population concernée au site d'offre le plus proche. Dans cet article, nous proposons une approche relative du concept de « proximité » dans le domaine de la localisation optimale, ce qui revient à la définir en fonction du contexte spatial propre de chaque point de demande. Pour ce faire, il s'agit de modifier la règle d'allocation de la demande aux sites d'offre en introduisant une notion de seuil naturel propre à chaque point de demande. Ce seuil naturel représentant un saut distinct dans l'ordre des distances à parcourir d'un point de demande vers un site d'offre. Toutefois, cette approche de la proximité demeure une piste de recherche puisque qu'elle n'a pas encore fait l'objet d'une validation rigoureuse requérant une réelle confrontation avec la réalité, notamment par le biais d'une étude minutieuse du comportement spatial des utilisateurs
