Abstract
The permanent growth of urbanization will bring the world's urban
population to more than 68% of the world's population by 2050. This means that urban
problems will be elevated to a higher level than today. Improper and increasing
consumption of natural resources, increasing waste, malapropos design of urban
environments, asymmetric development of the urban area, infrastructure problems, low
productivity, and inadequate quality of life are some of the urban problems that must be
solved seriously and quickly. City 4.0 is a solution that has been implemented to solve
the urban area and urbanism problems. City 4.0, in which using smart digital
technologies in the context of industry 4.0 creates quicker control, real-time
information flow, and more sustainable urban planning in urban management. It keeps
the ability of future generations to meet their own needs and requirements while
meeting the current needs of people in all areas, such as economic, environmental, and
social areas. To achieve sustainable urban development goals and overcome barriers,
City Information Modeling (CIM), in which information modeling techniques are used
to prepare dynamic modeling, simulation, visualization, and analytics to present realtime responses for stakeholders' demands, has been coming out. In this chapter,
focusing on information modeling technologies, the necessary definitions for a smart
and sustainable city are provided, and by presenting the specifications of city 4.0, the
information modeling technologies used in it including blockchain, cloud computing,
fog/mist computing, edge computing, Building Information Modeling (BIM), spatial
information technology, cyber-physical systems, and digital twin are described. At the
end of this chapter, the characteristics of the city model (CI model) are stated in the
context of CIM and the challenges and barriers that must be overcome to increase the
quality of life are addressed
