The modern development of a city with the population exceeding one million is becoming increasingly impossible in the "classical" way. The key problem of any dynamically growing megalopolis is the backlog of infrastructure development or the inability of the latter to effectively meet the needs of all the elements of the city. At the same time, the city does not have an opportunity to provide new areas of land resources for its development. Different cities and countries find their solutions to this issue, and recently the concept of "smart city" has been gaining popularity. Exemplified by the city of Krasnoyarsk, the article examines the obligatory requirements for infrastructure (mainly transport infrastructure) within the concept of "smart". The current trends in the city's development and comparison of the expected results of the "smart city" concept are defined, the directions of the city infrastructure development to ensure the possibility of transition to the development within the "smart" concept are proposed. The research is carried out within the framework of the grant "Methodical Approaches to the Formation of the Concept of the Smart City Project within the Framework of the Development Trends for Digital Economy" with the financial support of the Krasnoyarsk Regional Fund for Support of Scientific and Technical Activity.
