Abstract
In modern conditions, due to the significant progress made by Russian scientists and specialists in the field of train flow compaction through the introduction of advanced systems of interval train control, the issue of selecting the most rational of them is becoming more and more relevant. The aim of the work was to approve the methodology of technical and economic evaluation of the efficiency of various systems of interval regulation on single-track polygons. Within the framework of the research the game theory in combination with simulation modelling with the use of process approach for simulation of on-duty personnel actions, agent-based approach for train operation mode selection, system dynamics for traction calculations were applied. The approach was tested on the basis of the Northern Latitudinal Railway, and payoff matrices for five systems were formed. The efficiency limits of the main interval control systems were determined depending on the track development of operation points of a single-track polygon, type of train timetable, train flow characteristics and other operating conditions. For the Northern Latitudinal Railway at the designed traffic sizes the optimal is the use of autoblocking with «fixed» blocks at partial-platoon timetable with two trains in a platoon, after carrying out a sufficient number of tests on operation in the autoblocking mode under similar conditions the maximum efficiency can be demonstrated by the system Anaconda developed by AO NIIAS. The proposed game-theoretic approach to select the most economically efficient traffic control system on a single-track polygon taking into account the local conditions of its operation can be used to rationalize the distribution of Russian Railways investments. The conclusions formulated as a result of its application do not contradict the basic provisions of the theory of traffic flows and complement the studies devoted to the interval regulation efficiency evaluation on single-track polygons.
