Download the Codata Focus on the City Centre of Bordeaux BORDEAUX August 20, 2018 Focus on the city centre of Bordeaux Both the prefecture of Gironde and the capital of the Nouvelle Aquitaine region, Bordeaux is the ninth largest city in France with more than 240,000 inhabitants. However, the city’s influence is much wider. The agglomeration has more than 850,000 inha- bitants and the urban area more than 1,200,000 inhabitants. Bordeaux has seen a succession of urban development projects over the past 20 years. After the development of the docks started in 1995, the creation of a tram network and the inte- gration into high-speed train lines, urban renewal has been a continuous process. It also integrates sustainable development as an important component of projects. The “Euratlantique 2030” project aims to develop the sur- roundings of the Saint Jean station through several hundred hectares of projects dedicated to housing, offices, shops and urban development. The latest Codata censuses carried out on 30/08/2018 on the Bordeaux urban unit identified 46 Commercial sites, 4 of the «Shopping streets» type, 26 of the «Commercial centre» type and 16 of the «Retail area» type. This report focuses on the city centre of Bordeaux. It is com- posed of documents directly extracted from the Codata Explorer online service. Of course, Codata Explorer allows you to edit the same docu- ments for each of the 7000 Commercial Sites studied. Our sales team is at your disposal for any information on this subject.

  • A Study on Connectivity and Accessibility Between Tram Stops and Public Facilities: a Case Study in the Historic Cities of Europe
    Urban Street Design & Planning 73 A study on connectivity and accessibility between tram stops and public facilities: a case study in the historic cities of Europe Y. Kitao1 & K. Hirano2 1Kyoto Women’s University, Japan 2Kei Atelier, Yame, Fukuoka, Japan Abstract The purpose of this paper is to understand urban structures in terms of tram networks by using the examples of historic cities in Europe. We have incorporated the concept of interconnectivity and accessibility between public facilities and tram stops to examine how European cities, which have built world class public transportation systems, use the tram network in relationship to their public facilities. We selected western European tram-type cities which have a bus system, but no subway system, and we focused on 24 historic cities with populations from 100,000 to 200,000, which is the optimum size for a large-scale community. In order to analyze the relationship, we mapped the ‘pedestrian accessible area’ from any tram station in the city, and analyzed how many public facilities and pedestrian streets were in this area. As a result, we were able to compare the urban space structures of these cities in terms of the accessibility and connectivity between their tram stops and their public facilities. Thus we could understand the features which determined the relationship between urban space and urban facilities. This enabled us to evaluate which of our target cities was the most pedestrian orientated city. Finally, we were able to define five categories of tram-type cities. These findings have provided us with a means to recognize the urban space structure of a city, which will help us to improve city planning in Japan.

  • Towards an Americanization of French Metropolitan Areas ?
    TOWARDS AN AMERICANIZATION OF FRENCH METROPOLITAN AREAS ? Vincent Hoffmann-Martinot Directeur de Recherche au CNRS CERVL-CNRS/ IEP de Bordeaux Domaine universitaire 11, allée Ausone 33607 Pessac Cedex/ France e-mail : [email protected] Paper presented at the Department of Political Science and International Relations, Universidad Autónoma de Madrid, February 2004, and at the International Metropolitan Observatory Meeting, 9-10 January 2004, Bordeaux, Pôle Universitaire de Bordeaux. The author expresses his gratitude to the LASMAS-IdL and to Alexandre Kych for having allowed him to use 1999 census data in application of the data exchange agreement between CNRS and INSEE, as well as to Monique Perronnet-Menault (TEMIBER-CNRS, Bordeaux) for her invaluable help in producing maps of French urban areas. I. Metropolization and urban sprawl in French metropolitan areas There are two main official measures of urbanization defined by the French census, INSEE (Julien 2000): 1. the urban unit (unité urbaine) fits the agglomeration concept. It includes two categories : a. the urban agglomeration : a group of communes whose population is at least 2.000 inhabitants + a continuity of the built environment, i.e. there are no gaps (agricultural land, forest) of more than 200 meters (a criterion also used in Switzerland) b. the isolated city : the same definition applied to a sole commune France had 1.995 urban units at the last census conducted in 1999. 2. officially introduced in 1996 in order to measure in a better way the so-called periurbanization phenomenon (urban sprawl towards distant suburbs), the metropolitan area (aire urbaine) includes : a. an urban pole (pôle urbain) = an urban unit with at least 5.000 jobs b.

These territories are indeed fast evolving areas that consist of a “third-area”, both urban and rural. The aim of this paper is to analyze the role played by heritage in agricultural landscapes of peri-urban areas. The paper is built around these following questions: what are the changes in agricultural landscapes in the framework of the fast urban sprawl, and what are their effects on practices, especially around heritage, and on the many stakeholders’ perceptions? With the help of visuals like aerial or ground pictures, maps, diagrams, interviews, this paper uses a panel of specific examples selected in Western Europe. A wide range of peri-urban situations has been chosen to show the different kinds of existing urban pressure on agricultural landscapes. Key words: peri-urban area, agricultural landscape, heritage, territories, stakeholders Résumé: Ce travail est ciblé sur les paysages agricoles périurbains qui sont particulièrement sensibles. Ces territoires périurbains, en évolution rapide, sont considérés comme des « tiers-espaces » à la fois urbains et ruraux. L’objectif de cet article est donc d’analyser la place du patrimoine dans les paysages agricoles des territoires périurbains. L’article est construit autour des questions suivantes : quels sont les changements des paysages agricoles dans le cadre d’une forte croissance périurbaine et quels sont leurs effets sur les pratiques, particulièrement patrimoniales, et sur les perceptions des nombreux acteurs.

  • What Is the Evolution of Residential Segregation in France?
    What is the evolution of residential segregation in France? Residential segregation refers to the unequal distribution in urban space of dierent categories of popu- lation. It can result from individual choices, motivated by the search for a sense of belonging, or from phe- nomena of relegation, linked in particular to the price of housing. How has it evolved over the long term? This note examines the fifty-five “urban units” in metropolitan France with more than 100,000 inhabitants between 1990 and 2015 based on census data. A specially designed visualization tool enables these urban units to be compared among themselves and over time with all their spe- cific features, and for dierent categories of population1. First, managers and professionals are one and a half times more unevenly distributed than industrial and service employees. In the Paris conurbation, this residential segregation has increased for both groups. Elsewhere, it has decreased on average for managers and professionals, but remained stable for industrial and service employees. Fewer of the latter live in a neighborhood, where they represent the majority of the 25-54-year-olds (one out of two in 1990, one out of three in 2015). By contrast, a growing proportion of managers and professionals live in neighborhoods where they represent the majority of the 25-54-year-olds (0.1 percent in 1990, 14% in 2015). The wealthiest 10% households, moreover, are dis- tributed as unevenly as the poorest 10%, except in Paris, where the richest are particularly segregated. Immigrants of European origin have a low and stable segregation index over time.

  • Delineating the French Urban Areas Ongoing Thoughts
    Delineating the French urban areas Ongoing thoughts Vincent Loonis, Vianney Costemalle Geographical repositories and methods division French national institute of statistics and economic studies (Insee) EFGS, Manchester, 11th October 2019 Vincent Loonis, Vianney Costemalle Delineating the French urban areas Introduction France has delineated its urban areas at a regular pace for the past 200 years. The current definition has remained unchanged since 1962. For the next delineation, to be published in 2020, Insee has to face new challenges. Easy-to-access geospatial information leads to: scholars and official bodies questioning Insee’s implementation of the definition. increasing the number of urban area definitions (based o, population densities or built-up areas). A solution may consist in studying the robustness of the various definitions, while finding a way to combine them. Vincent Loonis, Vianney Costemalle Delineating the French urban areas Introduction Territorial classifications are classifications. As such, they are subject to statistical conventions. Some of these conventions are: classical: thresholds on population, on density rates... specific to spatial information: distance, reference system, choice of geographical layers, quality of the latter. The question raised by Insee is how to measure the influence of geographical conventions on territorial classifications. We will illustrate our ongoing thoughts with two examples: a density-based definition a built-up-area-based definition Vincent Loonis, Vianney Costemalle Delineating the French urban areas density-based definition Figure: Urban center: a cluster of contiguous 1 km2 grid cells (excluding diagonals) with a population of at least 1 500 inhabitants and a minimum global population of 50 000 inhabitants after gap-filling.

For each pixel, our approach compares actual building density after smooth- ing to counterfactual smoothed building density computed after ran- domly redistributing buildings. We define as urban any area with statistically significant excess building density. We also define the urban cores of these urban areas in a similar manner. Finally, we develop novel one- and two-sided tests to provide a statistical basis to compare maps with different delineations, which we use to docu- ment the robustness of our approach and large differences between our preferred delineation and the corresponding official one.

  • Trends in Urbanisation and Urban Policies in OECD Countries: What Lessons for China?
    Trends in Urbanisation and Urban Policies in OECD Countries: What Lessons for China? FOREWORD This report is a joint OECD-CDRF project. It was undertaken in the context of OECD’s Programme on Regional Development of the OECD Public Governance and Territorial Development Directorate, under the supervision of Joaquim Oliveira Martins, Head of the OECD Regional Competitiveness and Governance Division (www.oecd.org/regionaldevelopment). The report was produced at the request of Mr. Lu Mai, Secretary General of CDRF, and prepared as a background paper for the 2009-2010 Development Report of the China Development Research Foundation (CDRF) "Urbanisation in China: For a People-Centered Strategy". Ms. Irène Hors, Adviser to the Secretary General, CDRF, and Mr. Du Zhixin, Senior Program Officer, CDRF, put forward the original idea of the project, ensured coordination with the Chinese partners and provided useful background information. Whilst China, as a whole, is less urbanised than OECD countries, it nonetheless has the world’s largest urban population, with over 600 million urban citizens today. Although the scale of China’s urbanisation and the growing number of metropolitan regions where this urbanisation is concentrated are unprecedented globally, issues confronting all levels of government in managing this growth are not unique. Most OECD countries have faced a wide range of urban management challenges, and are continuing to acquire valuable experience in doing so. This report provides a synthesis of trends in urbanisation and urban policies in OECD countries. One of the key messages for China is that a successful urban development strategy should build upon each urban region’s endogenous attributes, i.e.
