Georgy E. Davydov, Doctor of Economics, professor, President of National Association of Transporters Some results from the railway transport reform.

The article establishes that after more than 20 years of railway transport reform in the Russian Federation, the goals and objectives of attracting investment in the renewal of the freight car fleet and the wagon economy, as well as in car building, have been met and even exceeded. At the same time, the development of competitive markets in the field of cargo transportation have taken place, but on a limited scale (provision of wagons and repair services rendering).

Anton N. Lyashenko, lead consultant in the Ministry of Economic Development of the Russian Federation Goal setting of decision making in a fuzzy set of data in the field of multimodal transportation.

The study considers the statement of the problem of a technological solution in the field of organization of transportation and management of transport making it possible to select the best transportation option from the routes under consideration. An integrated approach was used to assess the rationality of routes and select the best of them, considering a wide range of criteria that characterize the main features of this course of carriage type, the limitation of transport dimensional characters and the requirements of cargo owners.


Keywords: multimodal transportation, a rational route, logistics, fuzzy set theory.

Gnilomedov, Head of the Traffic Service of the State Unitary Enterprise “Petersburg Metropolitan” Process approach to management of passenger transportation of the St. Petersburg Metro.

The St. Petersburg Metro has set a course for the development and implementation of a project which business model would ensure data storage and exchange on the infrastructure facilities in operation and the transportation process itself at all the stages of the life cycle of the metro as a means of subsurface transport for all transportation process participants. The concept of the Consolidated Control Center of the St. Petersburg Metro has become such a business model.

Oleg S. Valinsky, Deputy Managing Director, Head, Directorate of Locomotive Traction Alexander A. Vorobiyev, Doctor of Engineering Science, head of the department «Overground Transport Technological Systems» in Emperor Alexander I St. Petersburg State Transport University Method for calculating the friction coefficient of a locomotive wheel with a rail in a probabilistic formulation.

A technique has been developed that makes it possible to calculate the friction coefficient, considering the use of a friction activator in the system “electric locomotive wheel - rail” in a probabilistic formulation. Using the proposed method, it is possible to modify the empirical dependence given in the “Rules for Grade Computations for Train Operation” to calculate the friction coefficient when using various types of friction modifiers. The calculation was performed by using a friction modifier based on thermosetting epoxy resins.


Keywords: friction modifier, adhesion coefficient, wheel, rail, electric locomotive, locomotive, traction calculation rules for train operation.

Elena M. Volkova, Candidate of Economic Sciences, Associate Professor of the Department of Transport Economics in Emperor Alexander I St. Petersburg State Transport University Multimodal passenger transportation as a tool to increase the competitiveness of railway transport.

The purpose of the study is to identify the problems of railway transport functioning during the pandemic and develop ways to solve them through the development of multimodal transportation. To achieve the goal, we use methods and instruments of statistics. The information base of the study was the materials of open sources, periodicals, as well as Internet resources, including data from the official websites of transport companies. The main result is the recommendations for the development of multimodal routes on the base of railway transport in concordance with current conditions and global trends in transport mobility. The study proves that sustainable development of railway transport is possible if it is integrated in seamless transport systems of regions and cities. The obtained results and conclusions can be used by the management of transport companies and regulatory authorities in updating the transport policy and strategies.


Keywords: seamless transport systems, railway transport, multimodal transportation, passenger transportation, long-distance service, commuter service.

Razuvaev, Candidate of Economic Sciences, Associate Professor of the Department of “Economics of construction business and property management” Anastasia Yu. Ledney, Candidate of Economic Sciences, Associate Professor of the Department of “Economics of construction business and property management” Long-term post-event analysis of freight handling irregularity in railway transport.

It was revealed that the seasonal irregularity of freight handling in railway transport tends to decrease both in general and for individual types of cargo, and in the current organization of carloadings dominated by goods characterized by low seasonality. This contributes to the optimization of operating costs, the intensive use of the railway infrastructure and the rise in industry revenues. The conclusion is made about the practicality of increasing the uniformity of freight traffic using both tariff mechanisms and organizational and technological measures.


Keywords: railway transport, uneven loading of goods, long-term trends, operating costs, income.

Ilya A. Tetslav, Assistant Professor at the Airports and air transportation department in Saint Petersburg State University of Civil Aviation Methodological foundation for calculating the transportation service rate in the aviation sector.

The article considers the methodological foundation for calculating the transportation service rate in the aviation transport and logistics network using a discrete-event simulation model (DESM) of passenger service in an aviation transport and logistics center (AviaTLC). The author carries out calculations for the performance function of motion control in the transportation service through time. The article substantiates the necessity of administrative time minimization in AviaTLC to increase the transportation service rate.

Vladimir N. Lozhkin, Doctor of Technical Sciences, professor, of the Department of fire, rescue equipment and road management in University of state fire service of the Ministry of Emergency Situations of Russia Methods and results of control of hazardous air pollution by transport pollutants in the engine run and warm-up modes in Arctic Circle towns.

Dangerous air pollution by industry and transport for the period 2010 – 2019 has been studied in the Russian Arctic towns. It has been established that the poor performance catalytic converters at low loads at sub-zero temperatures might become an obstacle to solving the problem for transport use. A method is proposed for calculating pollutant emissions with exhaust fumes of transport Euro 3 – Euro 5 emission standards for the Arctic weather conditions. The theoretical approach is verified using data from transport experiments relevant for the northern regions of Russia.


Keywords: air pollution, pollutant emissions, Arctic, Northern Sea Route.
