Disproportions of the spatial structure of the city as a reserve for the development of the city frame: territorial and communication model and analysis of cellular data

Abstract

The work is devoted to the identification of existing imbalances in the spatial structure of the city and the assessment of reserves for improving the efficiency of spatial organization, primarily due to the development of the framework of the city as a stable structure-forming part of the spatial system of the city, characterized by a high degree of development. The subject of the study is the types of territories forming the framework of the city. The definition of the role and potential of individual territories is carried out by means of modeling using the methodology of constructing a territorial and communication model of the city of O.A. Bayevsky on the basis of the frame-tissue theory of A.E. Gutnov. The simulation results are compared with the analysis of mobile operator data on daily migrations of people in the city. As a result of the modeling, the territories were typified, the framework and fabric of the city were identified, as well as territories with disproportions of saturation with points of attraction and connectivity with the population. Comparison of the results of analytical modeling and visualization of real movements of cellular subscribers during the day confirms the significant disproportions of the spatial structure of the city of Vladivostok, expressed in its monocentricity. The prospects for improving the efficiency of the spatial organization of the city are associated with the need to move away from monocentricity through the development of local centers in the city districts. Clarification of the disproportions of daily migrations by city districts allows us to confirm the need and assess the reserves for the development of new growth points and business activity. The results of the territorial-communication model are compared with the results of the unevenly-zoned model of the city developed by the author earlier, built according to the method of A.A. Vysokovsky, which allows us to determine not only the existing configuration of the city frame, but also promising territories for its development. As a result of the work, recommendations are proposed for the development of the city's framework, and appropriate generalized directions of urban planning policy are proposed for the selected types of territories.
