Abstract
At the present stage of national economy development it's becoming more and more important to improve the quality of train traffic passing by railway lines due to the development of interval regulation not only on heavy-load double-track lines, but also on single-track lines, both projected and existing, where the increase in traffic volumes is forecasted. In the article the efficiency of using auto blocking with «fixed» and «moving» blocks on one of the single-track lines of the Eastern polygon at different traffic sizes is estimated. In order to correctly simulate the operation of the line, simulation modelling with the use of system dynamics (for traction calculations), process (in order to simulate the logic of actions of the dispatching apparatus) and agent-based (to simulate the movement of each train) types of modelling is involved. Nine scenarios of railway line operations under different traffic sizes were developed. Technical and sectional speeds were used as criteria for assessing the quality of line operation. As the size of traffic on the line under consideration increases, the more advanced system makes it possible to deal more effectively with the negative mutual influence of trains of different categories within the compacted flow and to ensure the passage of 38 pairs of trains with a section speed of 43 km/h and thus to master the prospective size of traffic with minimum expenditure on infrastructure development. Further research involves the introduction of additional modules into the developed model to assess the technical and economic efficiency of various interval regulation options, as well as for modelling the interaction between the infrastructure of railway lines and technical stations.
