Abstract
The article considers the development of methodological foundations and suggests methodological approaches to identify urban areas with signs of subcenters in the implementation of a polycentric model of urban development. It is demonstrated that the application of mathematical modeling of passenger flows contributes to solving the problem of urban areas differentiation according to criteria of transport accessibility, time costs and travel speeds. As part of the study, calculations of passenger flows and passenger turnover were performed on the example of the St. Petersburg agglomeration – using network and pre-network models. Comparing the values of transport demand and transport supply in the nodes of the network made it possible to identify the location of potential urban centers.
