Cities are now the basic center of activity of every human being. The development of globalization and urbanization in the world meant that functioning in the urban community has become a threat not only for residents, but also for the surrounding environment. The increase in the number of registered vehicles negatively affected the quality of life. The area of ​​engineering considerations has become the design of urban space based on the principles of sustainable development based on the Smart City concept. City managers, prioritizing the development of the city and the safety of its users, create management plans for urbanized urban areas, based on the policy of decarbonisation. Cyberports, compact cities or Smart Cities are no longer a dream about the future for society. People become residents and users of smart and resource-efficient cities, which face the challenges of the future and the unlimited and constantly growing needs of their users - residents. The article presents an analysis and assessment of the use of methods and tools of transport system engineering in the Smart City concept, based on the example of the analysis of the mobility of selected roads in the West Pomeranian Voivodeship in Poland. Improving the condition of the urban environment with the use of innovative engineering methods and tools, the transport system is currently a major challenge due to the deepening problem of mobility or the inability to develop new engineering projects in an urbanized urban area due to the maximum use of the spatial area of cities. The aim of the study is to indicate how the use of practical traffic modeling tools and the way of urban engineering development affect the functioning of cities in Poland. Detailed considerations on technological and engineering architecture in the city management process allows us to observe the direction of development of future Smart Cities.
