AbstractSmart cities and traffic applications can be modelled by dynamic graphs for which vertices or edges can be added, removed or change their properties. In the smart city or traffic monitoring problem, we wish to detect if a city dynamic graph maintains a certain local or global property. Monitoring city large dynamic graphs, is even more complicated. To treat the monitoring problem efficiently we divide a large city graph into sub-graphs. In the distributed monitoring problem we would like to define some local conditions for which the global city graph G maintains a certain property. Furthermore, we would like to detect if a local city change in a sub-graph affect a global graph property. Here we show that turning the graph into a non-trivial one by handling directed graphs, weighted graphs, graphs with nodes that contain different attributes or combinations of these aspects, can be integrated in known urban environment applications. These implementations are demonstrated here in two types of network applications: traffic network application and on-line social network smart city applications. We exemplify these two problems, show their experimental results and characterize efficient monitoring algorithms that can handle them.

This study explore ICT infrastructure in the towns of Paraná State, reflecting on the potential and limits of ICT in the local government and the possibilities of these cities developing into smart cities. A quantitative study was conducted using multivariate data analysis techniques. The data are secondary and were obtained through a Municipal Basic Information Study in Brazil in 2012. The main result was the identification of five distinct municipal clusters in terms of ICT use and infrastructure. The size of a town is not a determining factor for towns to use and make web based services available to its citizens. Many towns remain lacking in basic infrastructure, with every profile showing different needs. There are a few strong patterns of eGov development and local conditions that could be treated as the foundation for some different policy packages that would be appropriate in these five situations. There are aspects that characterize the challenges and potential of towns than the emphasis placed on eGov. These aspects should be considered in studies of eGov and smart city.

City Construction

With the continuous emergence and application of new technologies, the construction of smart cities has entered the practical promotion period. Since 2012, the pilot construction of smart city has been promoted by the government in China. On the basis of these practical experiences, this paper presents an overview of the latest technologies and applications for smart city construction in China and demonstrates that smart city strategy needs to be implemented according to local conditions, adhering to the people-oriented concept and using scientific and effective top-level design and planning. The construction of smart city is comprehensive system engineering, including the integration of geographic information sharing service platform, full-cycle management and control system of urban planning, construction and social management, as well as intelligent business information management system of gardening, water conservancy, environmental protection and other industries and departments. The information system (GIS), satellite remote sensing (SRS), global navigation satellite system (GNSS), Internet of things, mobile applications, cloud computing, visualization technology ware used to promote urban construction and sustainable development, and to meet the needs of future smart city development. Results show that centralized management is very important for the construction of smart city. The government plays a major role in the construction of smart city, which will be conducive to the development of new technologies and the effective use of smart city construction resources.

The article analyzes the problems of formation and implementation of technologies of “smart cities” through the prism of ensuring environmental safety and maintaining the political stability of a large city. It has been established that there are various aspects of the development of smart cities. An increased interest on the part of scientists, engineers, ecologists, politicians, government and international structures and institutions in the technologies of “smart cities” is noted. The focus of the study is on the fact that the range of real problems of a modern city includes the solution of problems of safety, ecology, harmonious formation of infrastructure, logistics and other aspects of its effective development. The effect of use of such technologies in the environmental sphere is considered in the context of maintaining political stability. The problem of radiophobia in Moscow is illustrated. The costs of the media functioning when covering environmental issues are indicated. The role of information and communication technologies as a toolkit contributing to development of smart cities is outlined. An example of Moscow metropolis radiation-ecological monitoring system is given. It is offered to replicate technologies of an integrated automated system for environmental monitoring of urban space. The authors complement the existing approaches to the study of smart city technologies in key aspects of ensuring environmental safety and maintaining political stability.

This paper presents the evaluation of usersХ experiences in three intelligent lighting pilots in Finland. Two of the case studies are related to the use of intelligent lighting in different kinds of traffic areas, having emphasis on aspects of visibility, traffic and movement safety, and sense of security. The last case study presents a more complex view to the experience of intelligent lighting in smart city contexts. The evaluation methods, tailored to each pilot context, include questionnaires, an urban dashboard, in-situ interviews and observations, evaluation probes, and system data analyses. The applicability of the selected and tested methods is discussed reflecting the process and achieved results.

The City

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.

In the twenty-first century different countries and cities are increasingly seeking to introduce quality improvements in their livelihoods, generate for its residents an environment that is called “smart city” on the basis of high technologies. The article shows that the emergence of a “smart” city is an objective necessity due to the rapid growth of cities in the present and in the future. “Smart” city is designed to solve life problems in cities and create conditions for the socio-economic development of cities and countries, and for a favorable stay of residents on its territory. There are a number of strategies to implement the concept of “smart”, but it is important for each urban settlement to develop its own approaches and projects.

The article is meant to analyze various strategies and models for the development of smart cities, as well as the concept of project financing of smart cities, proposed by Pietro Doran, one of the founding partners of the world’s first smart city built from scratch in South Korea — Songdo. The authors believe that Songdo’s financing model, based on P. Doran’s Project Model can be considered as an effective way to attract investment in greenfield projects for the development of «smart cities» in Russia on the basis of public-private partnership.
