The presentation of the problems of smart urban planning on the territory of the administrative-territorial units in Bulgaria requires attention to be paid to the development and application of information and communication technologies in the country, which play a major role in addressing the challenges facing the development of the smart cities of the future. The topic of smart urban planning globally is due to the fact that the majority of the world's population lives in cities, given that the process of depopulation of rural areas continues at the expense of increasing urban population, we can note that about 70% of the world's population now lives in the cities. The result of this process is an increase in the size of urban agglomerations, which necessitates the use of modern technologies as the only means without alternatives in the planning and management of smart cities in the future. For the creation of smart cities in individual countries, a globally coordinated approach should be used, as well as the development of internationally standardized technologies, which will enable better integration and interoperability of information and communication technologies in urban planning, which in turn, it will create an opportunity to achieve regional economic and catch-up growth for the lagging regions. The process of developing international standards related to the harmonization of information and communication technologies, as well as the implementation of policies for the implementation of best practices in the smart planning for the development of the smart cities in the future, necessitate rethinking the main indicators for assessing the impact of information and communication technologies for the development of cities and regions in individual countries.
