Abstract


This article deals with approaches to assessing the use of metro stations based on correspondence matrixes describing passenger movements. Telecom operators currently maintain mobile communication in the metro. This results in operators being able to track the entry and exit of passengers from the metro, determining when their mobile subscriber switches to a base station located in the metro (enters the metro) or to a base station in the city (exits the metro). Such anonymous data can be grouped by time to exclude the tracking of individual subscribers and presented for analysis. The final data are a so-called OD-matrix: for a certain time interval for each pair of stations, the number of passengers moving between these stations is known.  Usually, when analyzing transport systems, restoring such a matrix (i.e. actually forecasting passenger flows) is the main task. In this case, the forecast is not needed - all passenger flows are known. This article is devoted to the discussion of what can be the purpose of analysis under such a structure of source data.
