The City

A smart city is an environment that uses innovative technologies to make networks and services more flexible, effective, and sustainable with the use of information, digital, and telecommunication technologies, improving the city’s operations for the benefit of its citizens. Most cities incorporate data acquisition elements from their own systems or those managed by subcontracted companies that can be used to optimise their resources: energy consumption, smart meters, lighting, irrigation water consumption, traffic data, camera images, waste collection, security systems, pollution meters, climate data, etc. The city-as-a-platform concept is becoming popular and it is increasingly evident that cities must have efficient management systems capable of deploying, for instance, IoT platforms, open data, etc., and of using artificial intelligence intensively. For many cities, data collection is not a problem, but managing and analysing data with the aim of optimising resources and improving the lives of citizens is. This article presents deepint.net, a platform for capturing, integrating, analysing, and creating dashboards, alert systems, optimisation models, etc. This article shows how deepint.net has been used to estimate pedestrian traffic on the streets of Melbourne (Australia) using the XGBoost algorithm. Given the current situation, it is advisable not to transit urban roads when overcrowded, thus, the model proposed in this paper (and implemented with deepint.net) facilitates the identification of areas with less pedestrian traffic. This use case is an example of an efficient crowd management system, implemented and operated via a platform that offers many possibilities for the management of the data collected in smart territories and cities.

The paper focuses on the importance of robotics and artificial intelligence inside of the new urban contexts in which it is possible to consider and enhance the different dimensions of quality of life such as safety and health, environmental quality, social connection and civic participation. Smart technologies help cities to meet the new challenges of society, thus making them more livable, attractive and responsive in order to plan and to improve the city of the future. In accordance with the Agenda 2030 Program for sustainable development that intends the inclusive, safe, resilient and sustainable city, the direction of growth and prosperity of urban environments is pursued by optimizing the use of resources and respecting the environment. In the current society, robotic technology is proposed as a tool for innovation and evolution in urban as well as industrial and domestic contexts. On the one hand the users-citizens who participate dynamically in the activities and on the other the new technological systems integrated in the urban fabric. Existing urban systems that are “amplified” of artificial and digital intelligence and give life to smart cities, physical places that allow new forms of coexistence between humans and robots in order to implement the level of quality of life and define “human centered” innovative solutions and services thus responding to the particular needs of people in an effective and dynamic way. The current city goes beyond the definition of smart city. In fact, as said by Carlo Ratti, it becomes a "senseable city", a city capable of feeling but also sensitive and capable of responding to citizens who define the overall performance of the city. The multidisciplinary approach through the dialogue between designers, architects, engineers and urban planners will allow to face the new challenges through the dynamics of robot integration in the urban landscape. The cities of the future, in fact, will be pervaded by autonomous driving vehicles, robotized delivery systems and light transport solutions, in response to the new concept of smart mobility, on a human scale, shared and connected mobility in order to improve management and control of the digitized and smart city. Automation at constant rates as the keystone for urban futures and new models of innovative society. Through the identification of representative case studies in the field of innovative systems it will be possible to highlight the connections between design, smart city and "urban" robotics that will synergically highlight the main "desirable" qualities of life in the city as a place of experimentation and radical transformations. In particular, parallel to the new robotic solutions and human-robot interactions, the design discipline will be responsible for designing the total experience of the user who lives in synergy with the robots, thus changing the socio-economic dynamics of the city.

ResumenEsta investigación aporta bases científicas y metodológicas de diagnóstico territorial, relacionadas al efecto causal de las autopistas elevadas sobre su entorno inmediato. Para lograrlo se utilizan antecedentes históricos y normativos, pero también, el procesamiento de datos abiertos y la utilización de herramientas econométricas que dimensionan impacto. Los resultados identifican 11.893 hogares afectados por contaminación sonora, reducción en la edificabilidad, reducción en el valor de las propiedades y aumento en la probabilidad de robo o hurto. La Ciudad de Buenos Aires es la principal centralidad de la región en términos de empleo, producción y servicios del país. Esta condición sustenta la utilidad de las autopistas en términos económicos y de movilidad; sin embargo, enfrenta desafíos de impacto ambiental y calidad de vida, que deben ser priorizados en el marco de la agenda de cambio climático y vulnerabilidad de las poblaciones. En el documento se analiza además la evolución del modelo de ciudad con autopistas, sus transformaciones y las posibilidades futuras de estas infraestructuras en los entornos urbanos. Optimizarlas, reemplazarlas por túneles o derribarlas, son las principales acciones que las ciudades vienen desarrollando, específicamente para la recualificación de zonas céntricas, frentes costeros y entornos barriales.AbstractThis research provides scientific and methodological bases for territorial diagnostics, related to the causal effect of elevated expressways on their immediate surroundings. To achieve this, historical and normative background is used, but also, the open data processing and the use of econometric tools that measure impact. The results identify 11.893 households affected by noise pollution, reduction in buildability, reduction in property value and increase in the probability of larceny or robbery. The city of Buenos Aires is the main centrality of the region in terms of employment, production and services of the country. This condition underpins the usefulness of expressways in terms of economics and mobility; however, it faces challenges of environmental impact and quality of life, which must be prioritized within the framework of climate change and the vulnerability agenda of populations. This document also analyses the evolution of the city model with motorways, their transformations and the future possibilities of these infrastructures in urban environments. Optimizing them, replacing them with tunnels or demolishing them, are the main actions that cities are developing, specifically for the re-qualification of central areas, coastal fronts and neighborhood environments.

Virtual 3D city models can be stored and exchanged in the CityGML open data model. When dynamic phenomena in 3D cities are represented with a CityGML application domain extension (ADE), the objects in CityGML are often used as static background, and it is difficult to represent the evolutionary process of the objects themselves. Although a construction process model in building information modeling (BIM) is available, it cannot efficiently and accurately simulate the building construction process at the city level. Accordingly, employing the arrow diagramming method, we developed a CityGML ADE to represent this process. We extended the hierarchy of the model and proposed the process levels of detail model. Subsequently, we explored a mechanism to associate the construction process and building objects as well as the mechanism to automate construction process transitions. Experiments indicated that the building construction process ADE (BCPADE) could adequately express the characteristics of this process. Compared with the building construction process model in the architecture, engineering, and construction field, BCPADE removes redundant information, i.e., that unrelated to a 3D city. It can adequately express building construction processes at multiple spatiotemporal scales and accurately convey building object behavior during building evolution, such as adding, removal, merging, and change. Such characteristics enable BCPADE to render efficient and accurate simulations of the building construction process at the city level.

The present paper investigates the characteristics and best construction strategies of smart cities around the world, as well as the determining factors of the satisfaction of the quality of life and the importance of the value of environmental sustainability. A case study of the city of Kalampaka and its residents was examined. The survey was conducted between July 2016 and August 2016. The selection of the sample was done by using the method of simple selection and includes a random sample of N=150 individuals. Statistical analysis showed that resident’s knowledge about smart cities was fairly good (48% of sample knew the phrase “smart cities”). Furthermore, they believe that the appearance of the city of Kalampaka needs improvement (75% of sample is disappointed with the current appearance of the city). Regression analysis showed that the value of environmental sustainability is greatly influenced by the energy saving, as well as, innovation has an impact on the level of quality of life. Older people seem to be satisfied with administration’s efforts.

To take the initiative of smart cities to new heights is a responsibility of every citizen. Bona fide progress will be seen when people's approach towards their city will change through awareness and education about the prevalent systems. This paper focuses on improving the cultural aspects of a smart city, especially visually, and on improving governance with reference to the 21st century. A majority of the information deals with the must-haves of smart city, later moving on to more specific problems. In the following paper, evaluation, analysis, ideas, innovative solutions along with comparisons and examples from life have been suggested with a view of enhancing the pre-existent, and further developing the cultural infrastructure of a smart city. This is proposed in a way that will help old traditions and historical heritage keep pace with modernism and other urban developments in the age of internet without changing their essence. This, in turn, will lead to touristic developments. Attention has also been paid to heritage restoration and its methods. Special focus has been given to the aesthetics of proposed, self-designed signage systems of the city. It is hoped that the insights presented herewith encourage greater enthusiasm towards art and encourage appreciation towards the culture and heritage of a smart city. This will add value to the quality of life of its citizens.

Contemporary cities are witnessing momentous shifts in how institutions and individuals produce and circulate data. Despite recent trends claiming that anyone can create and use data, cities remain marked by persistently uneven access and usage of digital technologies. This is the case as well within the emergent phenomenon of the ‘smart city,’ where open data are a key strategy for achieving ‘smartness,’ and increasingly constitute a fundamental dimension of urban life, governance, economic activity, and epistemology. The digital ethnography has extended traditional ethnographic research practices into such digital realms, yet its applicability within open data and smart cities is unclear. The method has tended to overlook the important roles of particular digital artifacts such as the database in structuring and producing knowledge. In this paper, we develop the database ethnography as a rich methodological resource for open data research. This approach centers the database as a key site for the production and materialization of social meaning. The database ethnography draws attention to the ways digital choices and practices—around database design, schema, data models, and so on—leave traces through time. From these traces, we may infer lessons about how phenomena come to be encoded as data and acted upon in urban contexts. Open databases are, in other words, key ways in which knowledges about the smart city are framed, delimited, and represented. More specifically, we argue that open databases limit data types, categorize and classify data to align with technical specifications, reflect the database designer’s episteme, and (re)produce conceptions of the world. We substantiate these claims through a database ethnography of the open data portal for the city of Calgary, in Western Canada.

In the ‘industry 4.0’ era, the phenomenon of digitalization of smart cities has gained increasing prominence, as it has the potential to address the problem of resource optimization and the pressure of demand of the growing urban population. In the past, smart city initiatives may not have created desired impacts as these initiatives were limited in scope, focusing on physical digital integration of the underlying systems of cities and of their citizens. This article examines the success factors that affect the digitalization of smart cities based on secondary research. To achieve smart cities’ core objectives of increasing quality of living, providing efficient and optimal services, thereby making the functioning of the city smart through digitalization, it is essential to look at these critical success factors, namely, sustainability, ecosystems and digital citizen. The article points out important elements such as lack of governance of sustainability, methods and processes to enhance participation of digital citizens and inadequate knowledge about structures and value creation through ecosystems that would need to be addressed while digitalizing smart cities. Given the required policy attention and focus, these factors would be expected to make smart cities sustainable, improve the quality of life of citizens and create new economic opportunities, while digitalizing them.
