The task of determining the optimal structure of the capacity of the rolling stock fleet of urban public passenger transport is considered.In the article,on the basis of the balance between the intensity of passenger flows and the carrying capacity of the rolling stock fleet of public transport.This balance is determined on the basis of the analysis of technical and economic parameters of large,medium and small capacity buses.The break-even intervals relationship on the route of buses of different classes is considered.The article formulates a mathematical model for calculating the optimal structure of the fleet taking into account the interaction of routes; provides an algorithm for solving the problem,based on the principle of directed enumeration of options.The results of applying the proposed method on the example of passenger transport in the city of Krasnoyarsk are presented.
