Nowadays, the popular term “smart city” implies the intertwining of several parallel social and technical processes in modern society. Firstly, it encompasses the process of scientific and technological progress and the constant diffusion of technology as well as their implementation into all spheres of human life. The second process is the desire to improve the quality of life and create comfortable living conditions, which characterizes the modern development of the urban environment. The third process reflects the transformation of a territorial management system, the use of innovative approaches to the allocation of resources as well as the setting of tasks and the coordination of their implementation. It is assumed that synergy across three processes should lead to the creation of new social values and urban sustainable development [1]. However, when the technological component is absolutized, there is a risk of giving in to the illusion of creating a “smart city” from typical technological units, and to believe that this design will work effectively. It becomes then obvious that for the effective functioning of new “smart cities” it is necessary to consider the adaptive capacity of the population, as well as the management factors that determine the resource provision of the territories. This paper takes that into consideration by providing results of a smart cities’ benchmarking identifying the most successful cases that could be of interest for better urban development. This research is committed with revealing successful cases from a systematic point of view, based on experts’ assessments. The collected data could be helpful for the researchers and practitioners who are going to make simulations involving smart cities.
