Simulation modeling in infrastructure modernization projects of the Russian part of the Central Eurasian Corridor

The article presents a brief characteristic of international transport corridors running through Russia. Their key nodes and the need for their sustainable development are identified. The use of structurization, analysis and synthesis methods allowed the study to obtain quantitative and qualitative characteristics of transport infrastructure facilities of Russian cities, through which the railway branches of the Central Eurasian Corridor pass. The rules of interaction between the key elements that make up the structure of each of the research objects have been established. A set of such rules and object characteristics became the input parameters for the simulation model of the problem domain. The problem area includes all bottlenecks in the transportation network formed by the intersection and merging of traffic flows. State diagrams illustrating the peculiarities of the behavior of object groups of the simulation model on the example of the city of Orenburg are developed.
