Solution of The Problem of Optimal Distribution of Cargo Flows in the Region and the Development of its Transport Network

This paper discusses the problem of optimal distribution of freight traffic with the best use of vehicles of road and rail transport, transport network, as well as their development, taking into account the prospective growth of freight traffic inthe conditions of the Surkhandarya region of the Republic of Uzbekistan.The mathematical model and a technique for solving the problem of optimal distribution of freight traffic in the region under consideration by types of land transport and transport networks are proposed.Using the example of the region under consideration, the results of effective distribution of the flow of cargo in the regional multimodal network, including taking into account the growth of traffic volumes, were obtained, areas wereidentified where the network capacity should be increased, their reconstruction and construction of new sections, taking into account various options.
