Objective: To develop a system of approaches, methods, and models for planning and forecasting the railway freight traffic using big data acquisition and analysis. This is conditioned by the today’s era of fierce competition, global digitalization, and a big amount of chaotic and multi-directional information flows, where the effective progressive development of transport systems depends very heavily on the methodology used for planning and forecasting freight traffic. The reliability of such a methodology is determined by the quality of the studied data sample, the integrity of analytical methods and procedures for their processing, and effectiveness. Methods: In order to classify the methods of planning and forecasting freight traffic, we have analyzed and systematized the main indicators of the transportation process, the degree of formalization of the methods used, and the general principles of their operation and obtaining forecast information. Results: Logical and comparative analyzes, synthesis of forecasting models made it possible to propose a conceptual approach to the practical application of the econometric methods and forecasting models used in foreign studies and analyzed cases. Practical importance: A technical approach to the use and scaling of the polynomial logit (logistic regression), the ARMA model (ARIMA) and the HIST algorithm of the Computing Center of the Russian Academy of Sciences has been proposed for forecasting the freight traffic and digitalization of planned and predictive business processes in the railway transport of the Russian Federation

Objective: To study the conceptual approach to the problem of integrated security, involving cooperation of transport logistical system participants of multimodal transportation (TLS SP), including aerial cargo delivery system, on the principles of the unity of information environment and intellectualization of transport systems management using the global positioning system GLONASS/GPS. Methods: The methods of TLS SP systematization and structural decomposition were applied, as well as the method of TLS SP matrix simulation, considering collaboration of the means of production in case certain operations are performed by each traffic participant on all route stages from a manufacturer to a receiver. Results: Horizontal decomposition of TLS SP was performed on the principle of the unity of the main transport process, taking into account integrated security requirements at each stage of goods traffic from a manufacturer to a receiver: making up, loading, transportation on different types of transport, cargo transfer and unloading at a receiving point. The main areas of transport intellectualization in Russia and abroad were studied. The new requirements for intellectualization of airport systems, air traffic control systems and aviation services were considered, presenting a unified aviation system and determining further directions of systems study, taking into account the perturbing factors at all stages and activities of the system in question. The suggestions on TLS SP intellectualization areas at all stages of planning and transportation fulfillment from a manufacturer to a receiver were given, making it possible to provide further development of supply chain management concept and formation of 5PL-provider transportation services at the market. Practical importance: The suggestions on the formation of TLS SP integrated security system were developed, using the latest data management technologies – intellectual transport systems, in order to improve the security and efficiency of transport processes, to minimize the delays and to improve working conditions.

Objective: To obtain technical equipment of infrastructure and terminal capacity relations in order to determine the necessary gridiron of tracks, as well as to assess efficiency and optimization of existing stations’ functioning. Methods: Based on synthesis and analysis of stations’ operation, as well as transport systems’ simulation modeling theory. Results: Parameters, influencing the present and designed terminal capacity, were identified. Cause-and-effect relations of events, resulting in railway machinery being brought in non-serviceable condition, are established. Dynamic system of indices was suggested, allowing for a more precise solution of the following tasks: to identify the necessary and sufficient gridiron of tracks for passing the specified amount of traffic, to assess the most probable amount of traffic at the station and its loading. Criteria of input and output flows of traffic at the station, as well as lay-over and trains' delays were stated, the former make it possible to analyze the suggested technical equipment and station functioning. Practical importance: On the basis of obtained relations it is possible to specify optimum relationship of trains’ lay-over time at station yards, the reserve of gridiron of tracks’ elements time in use and the number of routes being implemented at the station, as well as the necessary gridiron of tracks within the given аmount of train traffic. The results of the research may be applied in designing new railway stations, as well as optimization of station functioning and reconstruction of the existing stations.

Objective: Increasing reliability of mechanical gearboxes using a magnetic sensor, which will sig nifi cantly increase the reliability of transport mechanisms and systems in general. Methods: An analysis of incidents covered in the media was carried out. Results: Conclusions are drawn about the consequences of failure of mechanical gearboxes. To prevent emergency situations caused by a breakdown of a mechanical gearbox, it is proposed to use a magnetic sensor, which allows carrying out analysis and diagnostics of the gearbox and its components during operation. A mathematical model of a magnetic sensor is compiled and a block diagram of a device for processing the output signal of the sensor modulator is presented. Practical importance: Failure of a mechanical gearbox is a common problem that leads to a stop of transport mechanisms and systems. Detection of a mechanical gearbox malfunction can signifi cantly reduce the cost of repairs, as well as prevent unexpected damage to the mechanism, which can lead to a complete stop of the transport system. The use of a magnetic sensor in the traction gearbox of an electric train will reduce the likelihood of a traction gearbox breakdown during operation and reduce the cost of repairs, increase the reliability of the traction drive, and also simplify the commissioning of new electric trains and traction gearboxes.

The relevance of the study is associated with the study of viability resources of young city dwellers in the context of growing urbanization processes. The article presents theoretical and empirical research data regarding the problem of operationalization of the phenomenon of social and psychological satiety, which is a psychological state generated by peculiarities of the urban environment. The article presents concept description, gives data on its operationalization, formulates the hypothesis and shows some results of its empirical verification. The purpose of the study is to identify and analyse the interconnection between emotional experiences and preferred coping strategies with the state of satiety with living conditions in a metropolis in a group of young people. The major hypothesis of the study involves an assumption that there is a connection between feelings of satiety caused by the intense influence of the phenomena of the urban environment on the psyche and behavior of respondents, and their preferred methods of coping with the satiety situation. The study involved 159 people aged 19 to 30 years. Research methods: questionnaires developed by the authors and aimed at studying manifestations of social and psychological satiety (T. V. Drobysheva, I. V. Larionov). The questionnaire was used to identify socio-demographic characteristics. It is shown that in the group of respondents the state of socio-psychological satiety with living conditions in a metropolis is experienced as a feeling of apathy, boredom, irritation caused by imposed contacts with strangers, advertising activities of trading companies and overpopulation of the city. These phenomena of urban life are perceived by young people as violating their psychological privacy and making them want, first of all, to leave, to change the environment or activity, to find new forms of leisure or other places to spend their free time. The results found in the work indirectly indicate the protective function of socio-psychological satiety, expressed through the desire of respondents (young city dwellers) to reduce the intensity of negative emotional experiences related to living conditions in a metropolis. The questionnaires developed by the authors in the course of the study are of practical importance for researchers of the urban environment.

Abstract The relevance of the research topic is defined by the global level of significance of the problem of creation and safe operation of driverless transport on public roads. The research objective was to develop a mathematical model of the problem that allows forming a scientifically grounded strategy for driverless transport progress. The Zwicky Morphological Box method was used as a research method, which allowed building a structured set of intelligent transport system variants. Variables corresponding to the hard-surfaced road types, the level of informational support in the form of digital road models and the level of control tasks with increasing complexity were used as structural variables. A complex of tasks required to control traffic or driving in closed territories, on highways, suburban motorways passing through human settlements, urban streets, and yards has been defined. The control task complexes of each consecutive level include the task complexes of all the previous levels, and the digital road models of a higher level contain the digital models of all the previous levels. The analysis of the obtained results allowed building a trajectory of progressive development of the driverless vehicle focus area within the field of control task levels, road types, and their digital models.

We are presently witnessing a rapid paradigm change in software engineering: from objects to models. This chapter discusses some aspects of the emerging domain of model engineering, mainly those related to meta-modelling and uniform representation of models and meta-models. This much recalls the discussions on classes and objects that were taking place in the early eighties. In the last period, the issue of code interoperability has been dealt with such acceptable solutions as CORBA or the associated IDL language. But we are now witnessing the multiplication of non-executable models, as part of the evolving software development practice. In order to cope with this increasing complexity, a general and regular framework has to be defined. This is being achieved, in environments like the OMG, where all the new models are based on a precise meta-model and where all the meta-models are based on a common and unique meta-meta-model called the MOF. The MOF is rapidly gaining practical importance, between UML and XML, in the industrial strategy of several important companies. It is playing the role of a knowledge bus for all kind of models, object models or legacy models, product models or process models, existing models or yet to be defined models. In particular it is helping to provide a smooth transition from objects and components models to the business processes, workflows and service models that are becoming key elements in the area of Web services.
