Urban Data

Urban vitality is a key indicator for measuring urban development. This topic has been trending in urban planning and sustainable development, and significant progress has been made in measuring single indicators of urban vitality based on parcel or block units. With the continuous development of smart sensing technology, multisource urban data are becoming increasingly abundant. The application of such data to measure the multidimensional urban vitality of street space, reflecting multiple functions of an urban space, can significantly improve the accuracy of urban vitality analyses and promote the construction of people-oriented healthy cities. In this study, streets were taken as the analysis unit, and multisource data such as the trajectories of taxies and shared bicycles, user reviews and cultural facility points of interest (POIs) in Chengdu, a city in southwestern China, were used to identify spatial patterns of urban vitality on streets across social, economic and cultural dimensions. The correlation between the built environment factors and the multidimensional urban vitality on the street was analyzed using a multiple regression model. The spatial distribution of the different dimensions of urban vitality of the street space in Chengdu varies to a certain extent. It is common for areas with high social vitality to have production and life centers nearby. High economic vitality centers are typically found along busy streets with a high concentration of businesses. Areas with high cultural vitality centers tend to be concentrated on the city’s central streets. Land use, transportation, external environment, population and employment are all closely linked to urban vitality on streets. The crowd counting and POI density have the greatest impact on multidimensional urban vitality. The crowd and the level of service facilities profoundly affect social interaction, trade activities and cultural communication. The goodness of fit (R2) of the regression models for social, economic and cultural vitality are 0.590, 0.423 and 0.409, respectively. Using multisource urban data, our findings can help stakeholders better understand the spatial patterns and influencing factors of multidimensional urban vitality on streets and provide sustainable urban planning and development strategies for the future.

The essentially contested notion of the modern, and its cognate form “modernity,” have a long intellectual history. The emergence and dissemination of the idea of Western modernity was sometimes forcibly imposed, sometimes partially accepted, and sometimes resisted at different levels around the globe. Recent thinking has produced qualifiers and prefixes such as “unfinished,” “post-,” “late,” “inevitable,” “contra-,” “alternative,” or “differential” in relation to modernity, to signal the striations in approaches, interpretations, and positionings towards what is seen as an umbrella term to describe the various possibilities that can be brought to bear while considering contentions in contemporary theory and praxis. The social, economic, political, and cultural dimensions of this field of forces are integral to any thinking about the symbolic contestation of power in multifarious re-imaginings. This article charts this field mainly by looking at the colonial and postcolonial interventions that have impacted and continue to the present day to effect and inflect cultures and societies, including pressing questions of climate change and cyberspace. Sections are sorted under the following sub-headings: “The vortex of the modern;” “Subaltern bodies, subversive minds;” “Communication and colonization: Re-inventing space and time;” “Borderlands, migrations, identities;” and “Contesting and controlling cyberspace.”

This article examines the political possibilities for an aesthetic disruption of urban space and time. Locating the discussion within debates about the neoliberal city, selected art-works from Fierce live art festival in Birmingham, England are used in order to examine how, in a specific and localised context, normative spatial patterns and temporal rhythms can be challenged and subverted. The analysis draws on, and contributes to, a sociological account of the centrality of aesthetics to political and social organisation.

AbstractThis article examines the ways in which nationalism transformed Greek urban space during the nineteenth and early twentieth centuries. Through urban planning, architecture, archaeology, the destruction of Ottoman material remains and the promotion of Ancient Greek and (later) Byzantine heritage, urban space was gradually hellenized and cleansed of its Ottoman past. Specific examples, including the case of Thessaloniki, where the strong Ottoman character of the city was gradually effaced, are examined so as to outline the aims and the patterns of this transformation.

The Nine Forms of the French Riviera: Classifying Urban Fabrics from the Pedestrian Perspective. Giovanni Fusco, Alessandro Araldi ¹Université Côte-Azur, CNRS, ESPACE - Bd. Eduard Herriot 98. 06200 Nice E-mail: [email protected], [email protected] Keywords: French Riviera, Urban Fabrics, Urban Form Recognition, Geoprocessing Conference topics and scale: Tools of analysis in urban morphology     Recent metropolitan growth produces new kinds of urban fabric, revealing different logics in the organization of urban space, but coexisting with more traditional urban fabrics in central cities and older suburbs. Having an overall view of the spatial patterns of urban fabrics in a vast metropolitan area is paramount for understanding the emerging spatial organization of the contemporary metropolis. The French Riviera is a polycentric metropolitan area of more than 1200 km2 structured around the old coastal cities of Nice, Cannes, Antibes and Monaco. XIX century and early XX century urban growth is now complemented by modern developments and more recent suburban areas. A large-scale analysis of urban fabrics can only be carried out through a new geoprocessing protocol, combining indicators of spatial relations within urban fabrics, geo-statistical analysis and Bayesian data-mining. Applied to the French Riviera, nine families of urban fabrics are identified and correlated to the historical periods of their production. Central cities are thus characterized by the combination of different families of pre-modern, dense, continuous built-up fabrics, as well as by modern discontinuous forms. More interestingly, fringe-belts in Nice and Cannes, as well as the techno-park of Sophia-Antipolis, combine a spinal cord of connective artificial fabrics having sparse specialized buildings, with the already mentioned discontinuous fabrics of modern urbanism. Further forms are identified in the suburban and “rurban” spaces around central cities. The proposed geoprocessing procedure is not intended to supersede traditional expert-base analysis of urban fabric. Rather, it should be considered as a complementary tool for large urban space analysis and as an input for studying urban form relation to socioeconomic phenomena.

Considerando a dinâmica e a estrutura urbana de Belém no início do século XXI como expressão da acumulação das intervenções urbanas e das práticas de planejamento e gestão do espaço da cidade, analisa-se a genealogia do planejamento urbano para compreender a produção de um espaço que tem como característica a negação da natureza e a produção da desigualdade entre classes sociais. Nesse aspecto, identificou-se três períodos específicos que produziram impactos significativos na produção do espaço urbano de Belém: o terceiro quarto do século XVIII (1755 – 1777) com as reformas promovidas no período Pombalino na Amazônia, momento de expressão de uma modernidade urbana e arquitetônica; o final do século XIX e a primeira década do século XX (1890 – 1910), momento de ascensão da economia regional a partir da intensificação de atividades extrativas que produziram reformas urbanísticas com tons higienistas e; por fim, o período entre 1940 e 1970, que marcou uma série de propostas de planejamento com viés técnico-burocrático na produção do espaço. Do ponto de vista da metodologia adotada, estabeleceu-se como percurso de pesquisa: i) levantamento bibliográfico de caráter teórico e empírico da temática; ii) levantamento documental acerca das práticas de planejamento e intervenção dos períodos destacados com base em legislação, planos e projetos de cada um dos períodos; iii) coleta de iconografia representativa da época as quais as políticas foram executadas. Apresenta-se como resultados a hipótese de que a narrativa de uma pretensa ausência de planejamento como fator explicativo dos problemas da cidade é um discurso que não tem base na realidade, posto que historicamente é exatamente o oposto que a pesquisa indica, as modalidades de planejamento efetivadas em Belém acentuam problemas como a segregação socioespacial.Palavras-Chave: História, Planejamento Urbano, Modernidade, Belém.AbstractConsidering the dynamics and urban structure of Belém at the beginning of the 21st Century as an expression of the accumulation of urban interventions and planning and management practices of the city, the historical genealogy of urban planning is analyzed as a way of understanding production of a space that has as characteristic the negation of the nature and the production of the inequality between social classes. In this aspect, three specific periods were identified that produced significant impacts on the production of the urban space of Belém: the third quarter of the seventeenth century (1755 - 1777) with the reforms promoted in the Pombaline period in the Amazon, a time of expression of an urban and architectural design; the end of the nineteenth century and the first decade of the twentieth century (1890 - 1910), a time of great rise of the regional economy from the intensification of extractive activities that produced urban reforms with hygienic tones; and finally, the period between 1940 and 1970, which marked a series of planning proposals with a bureaucratic technical aproach in the production of space in Belém. This work established as following research methodology: i) survey bibliographical of theoretical and empirical character of the analyzed subject; ii) documentary survey of the planning and intervention practices of the highlighted periods based on municipal, state and federal legislation, as well as the master plans and development plans of the periods; iii) collection of iconography representative of the time to which the policies were executed in the urban space. The hypothesis is that the narrative of a supposed absence of planning as a factor of the city's problems is a discourse that has no basis in reality, since historically it is exactly the opposite that the research indicates, that is, the modalities in Belém accentuate problems such as socio-spatial segregation.Keywords: History, Urban Planning, Modernity, Belém.

In recent years, the phenomenon of depopulation and shrinkage of cities has been observed. The depopulation of large cities is undoubtedly a demographic fact. The process of urban depopulation has recently become the theme of numerous reports and alarmist research works. However, it can be concluded that the diagnostic background of this phenomenon has got a narrow methodical foundation. As a measure of depopulation, the number of permanent residents is usually taken (according to the place of residence). Thus, the diversity, complexity and dynamics of processes taking place in contemporary cities are ignored. Postmodern reality appears as a segregated, separated world. Therefore, the diagnostic approaches currently used should be discussed. Going further, one can conclude that the measurement of depopulation and shrinkage of cities by the number of permanent residents is a simplification, because it ignores the essence of urbanity, which is the diversity of values offered by the urban space of exchange (i.e. the utility value). The article presents therefore the new concept of the measurement for shrinking of cities. Ideas discussed in the paper are expected to stimulate critical exchange of views among urban researchers. In the authors’ opinion, the sin of social-economic geography and spatial economics consists in boiling down great human affairs to aspects of correct representativeness.

Geographic information systems can be defined as a intelligent tool, to which it relates techniques for the implementation of processes such as the introduction, recording, storage, handling, processing and generation of spatial data. Use of GIS in urban planning helps and guides planners for an orderly development of settlements and infrastructure facilities within and outside urban areas. Continued growth of the population in urban centers generates the need for expansion of urban space, for its planning in terms of physical and social infrastructures in the service of the community, based on the principles of sustainable development. In addition urbanization is accompanied with numerous structural transformations and functional cities, which should be evaluated in spatial context, to be managed and planned according to the principles of sustainable development. Urban planning connects directly with land use and design of the urban environment, including physical and social infrastructure in service of the urban community, constituting a challenge to global levels. Use of GIS in this field is a different approach regarding the space, its development and design, analysis and modeling of various processes occurring in it, as well as interconnections between these processes or developments in space.

The City

La Ciudad de Nueva York fue pionera en la aplicación de un sistema de planificación de control urbano que pusiera orden y concierto a una ciudad que rebasa los 5 millones de habitantes a principios del siglo XX. Tal complejo organismo urbano, inédito hasta ese momento, fue objeto del más ambicioso plan urbano sobre una ciudad construida.Este artículo se destina al estudio de este originario plan urbano de 1916, el cual sentaría las bases, unas ciertamente visionarias otras excesivas, de la construcción de la Ciudad de Nueva York en todo el siglo XX. La Building Zone Resolution se creó con dos fines: resolver los problemas de congestión humana en un espacio reducido, la ciudad del presente, y proponer una visión del espacio urbano en las décadas venideras, la ciudad del futuro.El artículo es un compendio de diez textos cortos y un epílogo, que junto a sus respectivos diez documentos gráficos, construyen el corpus de la investigación. El lector pues se enfrenta a un ensayo gráfico formado por pequeños capítulos que le sumergirán en los orígenes de la primera ciudad vertical de la historia.PALABRAS CLAVE: Nueva York; Planeamiento; Visión urbana.The city of New York was a pioneer in the implementation of an urban control planning system that set in order a city that exceeds five million people in the early twentieth century. Such complex urban organism – invaluable until that moment – was the target for the most ambitious urban planning on a built city.This paper focuses on the study of this initial urban planning from 1916, which would set the basis, certainly some visionary yet others excessive, for the building of New York City throughout the 20th century. The Building Zone Resolution was created with two purposes: to solve the issues related to the human bundle in a limited space, the city of the present, and to aim a vision of the urban space in the forthcoming decades, the city of the future.The article is a compendium of ten short texts and one epilogue, which in combination with ten graphic documents, frame the corpus of this investigation. Thus, the reader will face a graphic essay composed by a series of brief chapters that highlight the beginning of the first vertical city in history.KEYWORDS: New York; Planning; Urban vision.

R e s u m o O artigo problematiza a literatura crítica sobre o Projeto Eixo Tamanduatehy (Santo André) no sentido de enraizá-la na trajetória específica da cidade de Santo André e de contribuir com a reflexão sobre o significado das “experiências reais” de planejamento estratégico urbano no cenário atual da globalização neoliberal. Argumentamos que a ausência de uma leitura de três dimensões entrelaçadas dificultou uma compreensão adequadado legado deste projeto, isto é: (I) a construção política e contestada da escala local, além de seu significado para a disputa de hegemonia sobre a gestão urbana; (II) o planejamento estratégico,a neoliberalização e a emergência de uma representação hegemônica do espaço urbano a partirdo Projeto Eixo Tamanduatehy e (III) planos, projetos estratégicos e a emergência de novos espaços de representação.Palavras-chave Empresariamento urbano; planejamento estratégico; Projeto Eixo Tamanduatehy. A b s t r a c t In this paper the critical literature on the Project Eixo Tamanduatehyis highlighted in a problematic perspective, in the sense of embedding it within the specific trajectory of the city of Santo André, and to contribute with a reflection on the significanceof the “real experiences” of strategic urban planning in the present scenario of neoliberal globalization. Our argument is that the absence of an analysis on three interlinked dimensions has made an adequate understanding of the legacy of this project more difficult, that is: (i)the political and contested nature of scale, besides its significance for the hegemonic disputesover urban management; (ii) strategic planning, neoliberalization and the emergence of ahegemonic representation of urban space on the basis of the Project Eixo Tamanduatehy; and (iii) plans, strategic projects and the emergence of new spaces of representation.Keywords Projeto Eixo Tamanduatehy; strategic planning; urban entrepreneurialism;.
