The article provides a literary review on the redistribution of route networks, and also shows the possibilities of applying different approaches to the redistribution of route networks of SPB GUP "Passazhiravtotrans" from the point of view of opening a new bus fleet. The author substantiates the importance of using mathematical modeling in general for this purpose and modeling based on the concept of machine learning and the "digital twin", in particular, as perspective.

Background: Research in the direction of creating new technologies for loading and unloading bulk cargo is caused by market demand to reduce the cost of container transportation.

Aim: Formation of an original technology for unloading bulk cargo transported in containers, on the example of railway transport.

Methods: Theoretical methods of scientific research were used to achieve the goal: analysis, synthesis and modeling.

Results: An original model of design a container and a fitting platform for railway transport is offered. The appearance of the design and the device of the container are shown, and the stages of unloading the cargo are explained.

Conclusion: The practical significance is in the fact that the proposed model increases the competitiveness of railway transport.

Aim: The Moscow monorail transport system, which has been in operation for more than 18 years and uses a linear electric drive, has proven its efficiency, reliability, and safety, but at the same time there is a need to modernize it. The proposed modernization is based on new trolleys, in the design of which electromagnets and a linear motor are combined.

Materials and methods: Based on a model-oriented approach in Simscape – Simulink applications of the MATLAB ® environment, a dynamic model of a two-car rolling stock of a monorail transport system using magnetolevitation technology has been developed.

Results: A general description of the model and its subsystems is given. The results of modeling taking into account the nervousness of the track structure are presented.

Conclusion: The developed model allows you to choose the most rational design parameters of trolleys, elastic-dissipative suspension elements of rolling stock, electromagnetic control systems. The proposed monorail transport system can be implemented in Russian cities where, for various reasons, the use of the metro is impractical.

Background: There is a situation today where the major passenger buildings are lacking the required passenger traffic capacity. This issue has come about as a result of aligning the requirements of “the Federal Law on Transport Safety” into the buildings’ design. The problem remains relevant and therefore needs to be addressed.

Aim: The paper seeks to examine the correlation between the number of transport safety technical devices for scanning passengers’ bodies and luggage, the device operation time and incoming passenger traffic. This will be done in order to develop recommendations for changing the legislative framework in the field of transport safety and to estimate the advisability of using transport safety technical devices at railway stations, taking into account passenger traffic capacity.

Methods: The study is based on the theory of multi-channel public service system with an unlimited line. The calculations are based on the assumption, that the peak passenger traffic through the passenger devices is stationary.

Results: The paper finds the correlation between the number of transport safety technical devices, their capacity and the length of the line of passengers waiting for passing into the passenger buildings.

Conclusion: The results can be used as a feasibility study of transport safety technical devices, that are installed at the entrance of passenger buildings during their construction, reconstruction or modernization. For the existing buildings the found correlation will help to understand whether it is technically possible to provide the station with the required passenger traffic capacity or it will take capital investments for its reconstruction.

Background: Transport problems of Russian megacities are mostly consequences of motorization increasing and inefficient transport policy provided by local transport authorities. At the same time, the structure of urban transport markets is changing because of new business models of transport sharing emerging and development. Different models of sharing could be an important part of urban transport systems, but it requires initiative both of transport companies and local transport authorities.

Aim: to assess the state and determine the prospects for the development of the Russian carsharing market as a whole, as well as its largest segment (the carsharing market in Moscow).

Methods: methods of statistical analysis, graphical representation of information, summary, methods of analysis of industry markets (concentration index, Herfindahl –Hirschman index).

Results: In this article barriers for the development of transport sharing in Russian cities are identified, and forms of sharing integration in urban transport cities are developed.

Conclusion: The results obtained can be used by local authorities responsible for public transport services and the development of transport policy in Russian cities, as well as transport organizations engaged in multimodal transportation of passengers in megacities.
