Developing information and communication technologies are effective in city structures as in every field. Cities that cannot make use of technological facilities properly cannot respond to the needs and expectations of citizens. The purpose of this research is to reveal how participation can be developed in smart cities, why cities should turn into a smart city and to what extent smart city applications can be used. With digital transformation, the groundwork has been laid for the formation of a society model that can correctly interpret and process information in people's daily lives, question the environment they live in and adopt the principle of lifelong learning. It is aimed to increase the quality of life of citizens by saving cost, time, and energy. Smart cities are evaluated with six basic dimensions: smart economy, citizens, governance, mobility (incl. Transport), environment, and life. To achieve the objectives determined within the scope of this research, the description method was used. In the collection of data, a survey technique was used. The questionnaire created within the scope of the research was applied in the partner countries of the project: Bulgaria, Greece, Poland Spain, and Türkiye).
