The <i>urban analytics</i> expression is spreading out. To our understanding, it deals with the capability of <i>measuring</i> cities and their communities, as a support to their effective planning and management. In other words, being an analytically well-known city is a precondition for pursuing smartness. Urban planning is a very important item for city management and is interrelated with many layers, including urban environmental quality, air quality and well-being. Effective urban planning is based on the knowledge of quantitative parameters such as the <i>biotope area factor</i> (BAF), which was originally proposed for the city of Berlin and is currently used in other cities. The BAF index is used to evaluate the degree of soil permeability and measures, to a certain extent and from a specific point of view, how a city is eco-friendly. The usual way of evaluating the BAF is based on the manual construction of dedicated maps, using existing orthophotos and oblique imagery as a support. But this method is expensive, time-consuming and non-objective, as it is prone to different interpretations. The paper presents a newly-developed methodology for calculating the BAF. It is based on the use of existing digital cartography and on the application of geoprocessing techniques from GIS science: it is therefore fully automated and objective. The Pavia city (Northern Italy) is used as a testsite and a careful validation of the developed methodology is carried out, by comparison to 12 manually surveyed test areas, corresponding to 5% of the built-up areas of the municipality.

Young people are important to cities, bringing skills and energy and contributing to economic activity. New technologies have led to the idea of a smart city as a framework for city management. Smart cities are developed from the top-down through government programmes, but also from the bottom-up by residents as technologies facilitate participation in developing new forms of city services. Young people are uniquely positioned to contribute to bottom-up smart city projects. Few diagnostic tools exist to guide city authorities on how to prioritise city service provision. A starting point is to understand how the youth value city services. This study surveys young people in Braamfontein, Johannesburg, and conducts an importance-performance analysis to identify which city services are well regarded and where the city should focus efforts and resources. The results show that Smart city initiatives that would most increase the satisfaction of youths in Braamfontein  include wireless connectivity, tools to track public transport  and  information  on city events. These  results  identify  city services that are valued by young people, highlighting services that young people could participate in providing. The importance-performance analysis can assist the city to direct effort and scarce resources effectively.

Smart cities are complex, socio-technological systems built as a strongly connected System of Systems, whose functioning is driven by human–machine interactions and whose ultimate goals are the well-being of their inhabitants. Consequently, controlling a smart city is an objective that may be achieved by using a specific framework that integrates algorithmic control, intelligent control, cognitive control and especially human reasoning and communication. Among the many functions of a smart city, intelligent transportation is one of the most important, with specific restrictions and a high level of dynamics. This paper focuses on the application of a neuro-inspired control framework for urban traffic as a component of a complex system. It is a proof of concept for a systemic integrative approach to the global problem of smart city management and integrates a previously designed urban traffic control architecture (for the city of Bucharest) with the actual purpose of ensuring its proactivity by means of traffic flow prediction. Analyses of requirements and methods for prediction are performed in order to determine the best way for fulfilling the perception function of the architecture with respect to the traffic control problem definition. A parametric method and an AI-based method are discussed in order to predict the traffic flow, both in the short and long term, based on real data. A brief comparative analysis of the prediction performances is also presented.

The authors of this article purport that for current understanding of Healthy Cities it is useful to appreciate other global networks of local governments and communities. In a context where the local level is increasingly acknowledged as decisive in designing and implementing policies capable of tackling global threats such as climate change and their health-related aspects, understanding how thousands of cities across the world have decided to respond to those challenges appears essential. Starting with the concept of “healthy cities” in the 1980s, the trend toward promoting better living conditions in urban settings has rapidly grown to encompass today countless “theme cities” networks. Each network tends to focus on more or less specific issues related to well-being and quality of life. These various networks are thus not limited to more or less competing labels (Healthy Cities, Smart Cities, or Inclusive Cities, for instance), but entail significant differences in their approaches to the promotion of health in the urban context. The aim of this article is to systematically typify these “theme cities.” A typology of “theme cities” networks has several objectives. First, it describes the health aspects that are considered by the networks. Are they adopting a systemic perspective on all health determinants, such as Healthy Cities, or are they focusing on “hardware” determinants like Smart Cities? Second, it highlights the key characteristics of the networks. For instance, are they pushing for technological solutions to health problems, like Smart Cities, or are they aiming at strengthening communities in order to mitigate their detrimental effects, like Creative Cities? Third, the typology has the potential to be used as an analytical tool, for example, in the comparison of the results obtained by different types of networks in urban health issues. Finally, the typology offers a tool to enhance both transparency and participation in the policymaking process taking place when selecting and engaging in a network. Indeed, by clarifying the terms of the debate, decisions can be made more explicit and achieve a greater level of congruence with the overall objectives of the city. Indeed, Healthy Cities today need to make alliances with other theme networks, and this typology gives the keys to find which networks are the “natural best allies,” avoiding mutually harmful antagonisms. In that sense, the typology developed should be of interest to any actor involved in health promotion at the city level, whether in an existing “theme cities” policy process or as willing to participate in such a program, and to scholars interested in better understanding the main drivers of “theme cities” networks, a rapidly growing field of study.

Abstract. The smart city concept may aid in improving the city management, enhance the efficiency and thus increase the effectiveness of the city, where it is mainly focused on both information and technologies. This concept appears to be applicable for a smaller area such as university campus. Based on this idea, this research tries to implement the 3D smart campus for Universiti Teknologi Malaysia (UTM). This is an initial research towards a real implementation of 3D smart campus and conceivably 3D smart cities. This research focuses on the development of UTM smart campus by using 3D city modelling. The QGIS software was used to develop the 3D models. Then, the 3D model is viewed in a web browser for better 3D visualization and navigation. Furthermore, the results show that the 3D developed models for UTM smart campus can be a reliable platform to manage the spatial query and viewing the attributes of UTM campus buildings and facilities. This can be seen beneficial to the physical future development of the UTM campus area.

‘Smart Cities’ is a new and inventive approach that allows city management to use current infrastructure and resources more effectively. Participatory crowdsourcing is an effective method to collect data from the citizens, as it does not require costly new infrastructure and can be used by all citizens, regardless of their literacy level. To date, very few studies have investigated the usability these participatory crowdsourcing systems in a developing country context. The focus of this paper is then to provide a model for the usability of the IVR system to collect information from citizens to improve public safety in the city. The study makes use of a quantitative survey method. A questionnaire was completed by 361 participants of a public safety project hosted East London, South Africa. The data analysis was completed making use of factor analysis. The results indicated that efficiency and perceived satisfaction with the system was important elements that determined the usability of the system. The recommendation of the study is then that the city management must take these two elements in to account when designed or developing a participatory crowdsourcing system.

Smart Cities have grown in prominence due to advancement in ICT and the new paradigm of sustainable city management and development. Whilst many authors have proposed guidelines and framework for Smart City implementation, less attention has been given to the assessment of Smart City performance. The mainstream Smart City assessment framework generally entails the quantitative assessment of factors, elements and initiatives categorised under the Smart City dimensions. However, this approach is problematic and impractical because it requires a large amount of different baseline data that is often at times unavailable due to various reasons. This paper describes an alternative framework for smart city assessment, one that is based on the modification of Giffmger’s to make it amenable to leaner data. The proposed assessment framework was adopted to assess the smart city performances of Seoul, Singapore, and Iskandar Malaysia which were then compared. With the use of the framework for the performance assessment, the city that has performed better than the others is able to be identified.

Resumen: El objetivo de este artículo es demostrar que existe una poética en el urbanismo de Le Corbusier y que el tema se mantiene y se transforma en sus modelos teóricos y sus derivaciones. Desde el punto de vista teórico-metodológico, parte-se del presupuesto de que esa poética es el resultado de la dualidad entre arte y función presente en su pensamiento, originada en su formación personal y el momento histórico en el que produce su obra. El analisis se estructura con la agrupación de su produción urbanística en cuatro fases: 1-los años 1920: el Plan Ideal; 2-1929-38: las ciudades de América del sur y los viaductos; 3-1930-50: la Ville Radieuse; 4-Después de la Segunda Guerra Mundial: la ciudad de los 7V y la Unité d’habitation. La reflexión final retoma la visión general de su produción urbanística y la vincula al concepto de utopia. Abstract: The goal of this article is to demonstrate that there is an aspect of poetics in Le Corbusier’s urbanism and that this theme is maintained and you can see it being transformed through the theoretical models and its derivations. From the methodological and theoretical point of view, we make the assumption that the poetics is the result of the duality between art and function present in his thought, which comes from the historical moment in which his work was made and from his personal background. This analysis is structured by grouping his urban planning works in for phases; the 1920s: the Ideal City; 1929-38: the cities of South America and the viaduct; 1930-50: the Ville Radieuse; after the II World War: the city of 7V and the Unité d’habitation. The final considerations bring back the general vision of his urban planning works and tie it to the concept of utopia.  Palabras clave: Le Corbusier; Urbanismo; Poética; Arte; Función.

Abstract. It is well established that city life can impact on individuals’ mental well-being. Factors associated with modes of transport in a city, such as cycle corridors and the reliability of bus network, and environment factors, such as availability of green spaces, have been shown to relate to individuals’ well-being in the city. Smart cities contain a wealth of digital data which has been used in the management and organisation of cities. Such data is gathered from sensors, networks and systems which contain rich insights on factors associated with city life. Such as, for example, the availability of open spaces in the city, traffic congestion, and air quality levels. We propose that these smart city data sources and data flows can act as contextual cues to indicate the mental well-being of individuals in the city. That is, we propose harnessing indicators and patterns in datasets known to be associated with well-being, and using these as contextual cues for automated city well-being level estimation. In this initial investigation, we focus on contextual cues associated with active travel and transportation, environmental information and green infrastructure. We propose an AI-based system which uses these contextual cues to generate an indicator of mental well-being in the city.

Cities play an important role in the development of economies, generating wealth and well-being for citizens, providing better, energy efficient and sustainable services and giving residents their rightful place as the cornerstone of city management. Spain has a quite unique example of a smart city, Vitoria-Gasteiz. This is an emblematic city for Europe, which awarded this municipality the title of European Green Capital 2012. This paper seeks to analyse the best sustainable practices through a case study based on content analysis of this city's website. In the social dimension, the results highlight the promotion of resident participation through municipal services, to ensure public debate and transparency. In the environmental dimension, the city has a sustainable mobility plan that aims to reverse the trend towards an increased use of private vehicles by promoting the use of buses, trams and bicycles. Finally, in the economic dimension, the findings underscore the city's economic rigour, transparency in management and economic recovery.
