Quality assessment methods for subway traffic planning and management were analyzed as well as the connection of the above-mentioned with lifecycle phases of the projected traffic schedule. Versions for description of subway traffic planning results were considered, the connection of choosing one of them with the content of current control tasks was demonstrated. The parameters of the projected traffic schedule were determined influencing its stability in the “big” and “small” as well as the control quality in accordance with performance criteria and control objectives. The effect analysis of applying orthogonal transformations to different models of the projected traffic schedule was conducted. The quality assessment with the use of orthogonal transformations proposed by the authors showed its efficiency in evaluation of traffic steadiness as well as compliance with the fixed paired movement. The given method of presenting data may be used as an intermediate option of the extended and “complicated from the viewpoint of a one-sided survey” method for traditional data presentation of subway traffic planning results on the one hand and extremely concise average description by means of operating measuring instruments and integrated performance indices on the other.
