Visualising urban sustainability

Developing sustainable urban environments is complex and requires a number of factors – including social, economic and environmental sustainability - to be taken into account. This project is prototype software that produces a 3D virtual model of urban developments allowing viewers to see the short and long-term implications of courses of action

Indicators and Evaluation Tools for the Assessment of Urban Sustainability

This paper attempts to provide an explanation of why reductionistic approaches are not adequate to tackle the urban sustainability issue in a consistent way. Concepts such as urban environmental carrying capacity and ecological footprint are discussed. Multicriteria evaluation is proposed as a general multidimensional framework for the assessment of urban sustainability. This paper deals with the following main topics: · definition of the concept of urban sustainability, · discussion of relevant sustainability indicators, · multicriteria evaluation as a framework for the assessment of urban sustainability, · an illustrative example.Urban environmental carrying capacity, ecological footprint, multicriteria evaluation, NAIADE method

Enhancing urban sustainability through novel visualisation

Sustainable decision making in Urban Design is a complex and non-linear process that requires the interaction of a wide variety of stakeholders. The engagement of a range of stakeholders throughout the decision making process presents challenges including the need to communicate the complex and interdependent facets of sustainability and the need to demonstrate the short and long term implications of alternative courses of action.This paper presents the results of an initial application of a prototype simulation and visualisation tool (S-City VT) that was developed to enable all stakeholders, regardless of background or experience, to understand, interact with and influence decisions made on the sustainability of urban design. S-City VT takes the unique approach of combining computer game technology with computer modelling to present stakeholders with an interactive virtual development. The paper uses the Dundee Central Waterfront Development Project as a case study to evaluate the potential for the application of the tool and explains how parallel research work on the implementation of a sustainability enhancement framework for the Central Waterfront Development has informed the choice of sustainability indictors and identified the key stakeholders in the decision making processes.The paper shows how stakeholders can be presented with the outputs from the model using a 3D visualisation of the development and thus enables judgements to be made on the relative sustainability of aspects of the development. The visualisation tool employs a number of different methods of displaying the sustainability results to the stakeholders. These methods can show data in varying levels of complexity, depending on the expertise of the stakeholder, empowering all stakeholders by illustrating possible interactions between indicator values and sustainability and by showing how different stakeholder perceptions of the importance of the indicators can influence the sustainability assessment.Initial tests on the effectiveness of the different visualisation methods in displaying the model output to communicate the sustainability of the Development are described. The results of the tests and presented and discussed and conclusions are drawn on the further development and application of the tool to model and visualise through time the possible results of decisions made at different stages of the project

Enhancing urban sustainability using 3D visualisation

This paper presents the results of an initial application of a prototype simulation and visualisation tool (S-City VT) thatwas developed to enable all stakeholders, regardless of background or experience, to understand, interact with and influence decisions made on the sustainability of urban design. The tool takes the unique approach of combining three-dimensional (3D) interactive and immersive technologies with computer modelling to present stakeholders with an interactive virtual development. Use of outputs from the model and a 3D visualisation of the development can help decision-makers judge the relative sustainability of different aspects of a development. The tool employs a number of different methods to present sustainability results to stakeholders. Initial tests on the effectiveness of the different visualisation methods are described and discussed. The paper then presents some conclusions on further development and application of the tool to model and visualise possible results of decisions made at different stages of the project

Implementing transit oriented development in Greater London

This book provides new dimensions and a contemporary focus on sustainable transport, urban regeneration and development in eight countries spanning four continents at different stages of development. It examines the role of transit oriented development (TOD) in improving urban sustainability and providing different transport choices, exploring how these can be implemented in modern cities. Establishing a new agenda for TOD, experts in the field critically evaluate the links between urban transport investment and economic, social and environmental sustainability, introducing new methods of analysis. The chapters investigate the international dimensions of TOD, providing crucial insights into issues such as uneven development, transport emissions, global warming, car dependence and the challenge of powering vehicles with sustainable fuels. Urban and regional planning, transport studies and environmental management scholars seeking to understand urban sustainability issues will benefit from this timely book. It will also prove to be a valuable read for urban planners and research consultants looking to widen their knowledge of the role of TOD in enhancing urban sustainability

Modelling policies for urban sustainability

The objective of the EU research project PROPOLIS (Planning and Research of Policies for Land Use and Transport for Increasing Urban Sustainability) is to assess urban strategies and to demonstrate their long-term effect in European cities. To reach this goal, a comprehensive framework of methodologies including integrated land use, transport and environmental modelling as well as indicator, evaluation and presentation systems have been developed. Sustainable development is viewed as comprising the environmental, socio-cultural and economic dimension. About thirty key indicators have been defined to measure the three dimensions of sustainability, such as air pollution, consumption of natural resources, quality of open space, population exposure to air pollution and noise, equity and opportunities and economic benefits from transport and land use. Indicator values are derived from state-of-the-art urban land use and transport models. A number of additional modules, including a justice evaluation module, an economic evaluation module and a GIS-based raster module, have been developed and integrated to provide further indicator values. Both multicriteria and cost-benefit analysis methods are used to consistently evaluate the impact of the policies. The environmental and social dimensions of sustainability are measured using multicriteria analysis for the evaluation of the indicators, whereas cost-benefit analysis is used for the economic dimension. The modelling and evaluation system is currently being implemented in seven European urban agglomerations: Bilbao (Spain), Brussels (Belgium), Dortmund (Germany), Helsinki (Finland), Inverness (Scotland), Naples (Italy) and Vicenza (Italy). A large number of policies will be tested with the modelling and evaluation system in the seven urban regions. Policies to be investigated are land use policies, transport infrastructure policies, transport regulation and pricing policies and combinations of these. Besides a common policy set for all seven urban regions, city-specific local policies will be assessed as well. The first part of the paper will introduce the methodology and the modelling system developed. The second part will present first results of the policy testing and evaluation. The paper will conclude with initial conclusions on successful strategies to enhance the long-term sustainability of urban regions.

INDICATORS OF URBAN SUSTAINABILITY IN MEXICO

The principal objective of this project is to summarize the characteristics that define urban sustainability in Mexican cities; its basic principles and the advantages of their application in the development of future cities, as well as the description of the indicators of urban sustainability that directly affect the development of communities, from households, colonies or neighbourhoods to cities or regions. The project’s method is based on the analysis of bibliographical information and the revision of some practical cases that refer to the development of sustainable indicators in urban environment.Indicators, sustainability, urbanism, development, cities.

Mobile transitions : exploring synergies for urban sustainability research

Urban sustainability approaches focusing on a wide range of topics such as infrastructure and mobility, green construction and neighbourhood planning, or urban nature and green amenities have attracted scholarly interest for over three decades. Recent debates on the role of cities in climate change mitigation have triggered new attempts to conceptually and methodologically grasp the cross-sectorial and cross-level interplay of enrolled actors. Within these debates, urban and economic geographers have increasingly adopted co-evolutionary approaches such as the social studies of technology (SST or ‘transition studies’). Their plea for more spatial sensitivity of the transition approach has led to promising proposals to adapt geographic perspectives to case studies on urban sustainability. This paper advocates engagement with recent work in urban studies, specifically policy mobility, to explore conceptual and methodological synergies. It emphasises four strengths of an integrated approach: (1) a broadened understanding of innovations that emphasises not only processes of knowledge generation but also of knowledge transfer through (2) processes of learning, adaptation and mutation, (3) a relational understanding of the origin and dissemination of innovations focused on the complex nature of cities and (4) the importance of individual actors as agents of change and analytical scale that highlights social processes of innovation. The notion of urban assemblages further allows the operationalisation of both the relational embeddedness of local policies as well as their cross-sectoral actor constellations
