Information Modelling Technology

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<br>
