Exploring compact city : reconfiguring the compact city

Shrivastava, Priyanshu. January 2009 (has links)
Intent and aim The primary intent of this thesis is to explore about Compact Urbanism and to define an approach towards low density, mono functional precincts in the city that lie underutilized in their potential towards a positive contribution to the city and to come with new model of compact city that will answer the challenges and problems that are still unanswered. The reconfigured Compact city will built environment at the best possible way to support the best quality of life. Everyone wants to be free of the urban pollution he can directly sense: the smog, smoke, grime, litter, odors, city heat, din, poor water, and the slum conditions. But the environmental degradation associated with urban development can also be measured in terms of disrupted ecosystems and wasteful use of green space and natural resources. The approach illustrates how and why compact city is the way of redesigning an urban environment so as to get rid of these negative aspects and to preserve enhance the qualities of urban life that we have come to accept desirable. Eventually to reconfigure the compact city which will work better than what has been proposed so far. The new model of compact city will make neighborhoods more lively, safe and relevant for children; and so that the city itself becomes a more exciting center for personal interactions in today’s fast-moving world. Main Concerns Concerns rise from the observations that there are city structures that are inefficient and are underutilized areas in the cities which have lower intensity of use and untapped potential to absorb new functions, activities and housing stocks. As of by-product of mono functional use and low density these areas have issues like lack of identity, character and lack of a vibrant public domain. A Renewal process is important for such city precincts that are located near city centers or work centers and occupy large areas at low densities in relation to its location and potential. The notion of the Compact City is a reaction against the city structures in most developed cities-dense cores accommodating most of the cities workplaces, retail, entertainment, commerce, services and amenities and sprawling low-density, single use suburbs-a city structure which by default produces the need to travel and as a product car dependency, energy consumption and pollution. The basis for the debate is the general agreement that the city as we know and inhabit today causes unsustainable environmental stress, is socially stratified & functionally sub-optimal, and is expensive to run.  Challenges The city is a platform where humans meet, interact, collaborate, exchange their views, make new relationship, work and compete with each other. City forms a shell in which all lives survive and develop. It moulds their lives. It is a web where different kind of people varies in religion, ethnicity and race lives together. It interlocks them and makes a mass of variety of living and nonliving objects. All cities are fast growing. People are moving in and out of the cities. Each day somebody is transferred to some other place. Families are breaking up either of transfers of job or splitting of parents. New constructions are planning. Whether the new construction is required or not people are building it up without giving a thought how it will be beneficial to the environment. Because of all these impacts of improper planning, land value in the city is hiking up and eventually people are left with no option but to move outskirts of the city. New tracts of land are occupying. Green places are disappearing. The challenge has to do with conservation. The fast growing encroachment towards the countryside of the city is destroying valuable green fields. They are affecting the farm lands which are essential for human life in order to get food for unstoppable population. There is a need of getting control over the growth of the city. There should be more functional and organized planning which can curtail sprawl. We have to comprehend the significance of land as it is not infinitive, it is limited. The city should be redesigned or proper measures and consideration are to be made in order to conserve land, water, energy and waste. If irregular spreading of city is not stopped and compact cities are not implemented than we will lose valuable lands and will not be able to acquire benefits of natural environment as it will be destructed. Compactness has to be achieved to build environment to support best quality of life. / Literature survey -- Methodology -- Case studies -- Social implications of compact city -- Compact city guiding principles. / Department of Architecture

Mobilidade e adensamento urbano: aplicação de indicadores em estudo de caso no Distrito da Barra Funda, São Paulo / Urban mobility and density: application of indicators in a case study in Barra Funda district, Sao Paulo.

Fortes, Melissa Belato 31 October 2012 (has links)
O objeto desta pesquisa é a relação entre o adensamento, a multifuncionalidade e a mobilidade urbana mais sustentável, sendo que o objeto concreto são as áreas sem uso ou subtilizadas do Distrito da Barra Funda, em São Paulo, de forma a serem consideradas como unidades de planejamento urbano integrado, tendo o Rio Tietê e a ferrovia como eixos estruturantes. O adensamento e a multifuncionalidade contribuem para uma mobilidade urbana mais sustentável que é incentivada pela proximidade entre o local de moradia e as demais atividades, como o local de trabalho, a escola, o comércio e os serviços, entre outros. Assim, os percursos para pedestres e ciclistas, bem como a articulação com os sistemas de transporte coletivo, são priorizados frente ao transporte individual. Partindo dessa premissa, o objetivo do trabalho é qualificar e quantificar essa relação por meio da aplicação dos conceitos, das estratégias e dos indicadores de mobilidade urbana. Para tanto, o trabalho foi estruturado em quatro etapas: a primeira refere-se à fundamentação teórica e ao levantamento dos indicadores; a segunda refere-se à caracterização do problema da mobilidade na Região Metropolitana de São Paulo (RMSP); a terceira refere-se à análise e síntese e a quarta refere-se à proposição e às considerações finais. Com base na aplicação dos conceitos, das estratégias e dos indicadores de mobilidade urbana selecionados, esses foram calculados para a situação atual e para a situação proposta, onde foi possível se verificar a melhora substancial nos resultados para os cenários que condizem com os modelos teóricos pesquisados, nos quais a cidade que melhor corresponde aos princípios de sustentabilidade, a que otimiza os recursos e é mais eficiente, é a cidade policêntrica e adensada. Como resultados têm-se o aumento de 15 vezes na área servida por percursos de bicicletas, o aumento de 42% das áreas de calçadas e a elevação da velocidade do transporte coletivo motorizado de 15 km/h para 25 km/h, impactando diretamente na redução de 40% nos tempos de viagem desse modal. Todas essas ações, aliadas ao adensamento populacional, aos usos mistos, à introdução de áreas verdes, à melhoria da microacessibilidade por meio da transformação dos atuais obstáculos - a ferrovia e o Rio Tietê - em elementos integradores, entre outros, fomentariam deslocamentos em distâncias menores, passíveis de serem realizados em transporte coletivo, a pé e de bicicleta, fomentando, inclusive, um maior convívio social. A execução de ações nesse sentido se torna emergente numa cidade com sérios problemas estruturais, onde muitos deles são relacionados à mobilidade, à qualidade ambiental, à diversidade espacial e à densidade de ocupação. / The subject of this research is the relationship among density, mixed-use and a more sustainable urban mobility; the intervention area comprises the unused and the underutilized areas of Barra Funda District, in Sao Paulo, in order to be considered as units of an integrated urban planning, with the Tiete River and the railway as structural axes. The population density and the multifunctionality contribute to a more sustainable urban mobility which is intensified primarily by the proximity between housing and other daily activities at workplace, school, trade and services, among others. In this scenario, pathways for pedestrians and cyclists, as well as conexions with the public transportation systems are prioritized compared to individual transport. Starting from this premise, the objective of this research is to qualify and quantify this relationship between density and mixed-use by applying concepts, strategies and indicators for urban mobility. Thus, the work was divided into four stages: the first refers to the theoretical basis and the indicators survey, the second aims the characterization of the mobility problem in São Paulo metropolitan area, the third refers to the analysis and synthesis, and the fourth presents a proposition and the final considerations. Based on the application of concepts, strategies and selected indicators for urban mobility, these were calculated for the current situation and the proposed situation, when it was possible to verify the substantial improvement for the scenarios that are consistent with the theoretical models researched, suggesting that the city that best reflects the principles of sustainability, which optimizes resources and is more efficient, is the polycentric and dense city. As a result we have a 15-fold increase in the area served by bike paths, an increase of 42% of pedestrian pathways and a speed increase in motorized public transportation from 15 km/h to 25 km/h, which has a direct impact on reducing commutting time in 40%. All of these actions, combined with the higher population density, mixed-uses, introduction of green areas, improving of microaccessibility by transforming the current obstacles - the railway and the Tiete River - in integrative elements, among others, would promote commutting in shorter distances that could be performed in public transport, walking and cycling, encouraging even greater social interaction. The implementation of these kind of actions is needed in a city with serious structural problems, many of them related to mobility, environmental quality, spatial diversity and occupation density.

Compact sprawl : Exploring public open space and contradictions in urban density

Ståhle, Alexander January 2008 (has links)
Twentieth century urbanization has left a tremendous footprint on the globe. It is generally speaking a spread out fragmented suburban and exurban landscape continuously growing according to what has been called sprawl-like development, increasing energy and automobile dependency, challenging urban sustainability. Recently urban growth has also turned inwards because of economic and political change. Thus one of the main challenges for future urban design will be to ‘compact sprawl’. This thesis, set in the field of urban morphology, explores the spatial conditions for suburban densification by looking at administrative and user-related measures of density, public open space, and pedestrian accessibility. If we consider useful open space, it would not decrease density, but rather increase spatial compactness. So would also a well-connected street network, if we consider accessibility as part of density. The thesis’ first four papers explore new measures that contradict ordinary notions of density and the last three papers examine densification scenarios on different urban scales in collaboration with urban planners in practice. The paper Place syntax explores a possibility to combine the space syntax description of cognitive accessibility, axial line distance, with place attraction into a combined attraction-accessibility analysis model. Empirical investigation shows that place syntax analysis captures pedestrian movement and can be used for new types of location density analyses. Sociotope mapping describes the theoretical body of a new urban planning tool called the “sociotope map” (sociotopkarta) developed in Stockholm planning practice. The map emphasizes that the same public open space can have different direct use values for different people and thereby assesses qualitative open space area. Exploring Ambiterritory investigates the notion of (sub)urban no-man’s-land. Densification most often means increased open space use, which naturally leads to an increase of potential conflicting territorial interests. However, the reduction of vague user space and unclear legal territories by densification can increase the size of useful open space. More green space in a denser city investigates whether little public green space means low accessibility. User questionnaires and GIS-analyses in ten city districts in Stockholm correlate and show that it is possible to have more accessible green space in a denser city. Strategic exurban landscape densification investigates different municipal location strategies and development rates in the municipality of Kungälv. Results show that location strategies create the biggest landscape impact and not development rates. Greening metropolitan growth analyzes the density landscape in Stockholm county region and finds some correlations with health and socioeconomic variables. Growth scenarios in the regional plan for 2030 show decreasing compactness and spaciousness in inner suburbia. Compact sprawl experiments use the measures developed in the former papers on four densification scenarios in two suburbs in Stockholm. The results show how it is possible to efficiently compact modernist sprawl, particularly the inner suburbs. It is likely that we will be more dependent on walking, bicycling, and public transportation in the future. Street networks and public open spaces are then key issues today just as they were at the end of the nineteenthcentury, creating compact, sustainable, liveable, equitable, and more competitive cities. In fact, many compact urban cores such as in Stockholm, London, and Manhattan have through the 20th century persistently stood up to the competition against more sprawling cities. The thesis shows that compacting inner suburbia seems to be the new frontier many cities and planners are facing. In fact, this is a vast unexplored field that needs further attention in urban studies and urban morphology in particular. / QC 20100913 / Stadsform och hållbar utveckling

The discussion of the issue required an analysis of the relations between density and the performance of the urban organism. A simulation was made to foresee the densification of a sample of Tambaú district following the present legislation and the tendencies of the property market and the impact of this densification on the local traffic was pointed out. The research has shown that the instrument in question and the other relevant legislation are not able to control effectively the local density / O presente trabalho discute a questão do gabarito escalonado em vigor na orla marítima de João Pessoa - PB (bairros do Cabo Branco, de Tambaú e de Manaíra), buscando esclarecer os princípios e conceitos que fundamentaram a adoção desse mecanismo. Para embasar a discussão do tema, analisaram-se as relações entre a densidade e o funcionamento do organismo urbano. Foi simulado um adensamento em conformidade com a legislação vigente e as tendências do mercado de um trecho do bairro de Tambaú e verificaram-se as repercussões dele no funcionamento do sistema viário. Constatou-se na pesquisa que a legislação em vigor na área sujeita ao gabarito escalonado não consegue controlar de forma eficaz a densidade local

A dissertação está apoiada em um referencial teórico sobre o Papel do Estado na Regulação do Espaço Urbano, a Função Urbanística da Legislação, os Instrumentos de Regulação Urbana no Brasil no Marco da Constituição Federal de 1988 e a regulação urbana estatal e as suas reformulações a partir do Estatuto da Cidade. O campo empírico centra-se na avaliação dos impactos da Lei de Uso e Ocupação do Solo - 16.176/96, no bairro de Boa Viagem, verificando como a ação do mercado imobiliário se vincula aos parâmetros urbanísticos, na forma como foram aplicados. Analisa-se, também, a influência desses atores - poder público e instituições privadas ligadas ao mercado da construção civil, seus interesses e as consequências para a transformação da paisagem urbana na qual foram aplicadas. / The research presented here aims to evaluate the implications of urbanistic regulation in the ordering and production of urban space, and has as object of study an analytic study about the consequences of the application of the normative instruments of Municipal Law number 16.176/96 in the Boa Viagem district burrough, in Recife, Pernambuco. This thesis is supported by a theoretical background concerning the role of the State in the regulation of urban space, the urbanistic function of legislation, the instruments for urban regulation in the 1988 Federal Constitution, and the State-sponsored urban regulation and its reformulation after the passing of the "Estatuto da Cidade". The empirical portion focuses on the evalution of the impacts of the "Use and Occupation of Land Law" in Boa Viagem, by analyzing how the dynamics of the real estate market are linked to urbanistic parameters, in the manner in which they have been applied. An analysis is also conducted on the influence os this parties -- the State and private institutions related to the construction business, and on their interests and the consequences of such influences and interests, more specifically, how they have influenced the transformation of the urban landscape.

Admissible height and urban density of buildings for the Prospective Management of Seismic Risk in residential areas

Herrera, Fabiola, Mamani, Flaby, Arana, Victor 30 September 2020 (has links)
El texto completo de este trabajo no está disponible en el Repositorio Académico UPC por restricciones de la casa editorial donde ha sido publicado. / This research proposes limit values of height and population density of buildings for a Prospective Management of Seismic Risk in residential areas. The analysis of an efficient evacuation of buildings to the street or refuge area was carried out, evaluating human behavior with models based on the agent, the influence of buildings and the urban parameters of the city with three-dimensional models (BIM) for a severe seismic scenario. The present article establishes that the maximum permissible height of buildings projected in a residential avenue is directly related to the width of the available refuge zone to guarantee the correct evacuation of said zone during a severe seismic event. In addition, an evaluation of a real existing scenario is made in a section of a residential avenue.
