Mathematical Models of Effective Topology of Computer Networks for Electric Power Supply Control on Railway Transport

The paper is devoted to analysis of modern directions of innovation-investment formation of intelligent computer networks that control the fast-moving technological processes of electricity supply. It is based on the conclusion that the problem of increasing the productivity of information exchange between information resources and consumers is dominant. A method for increasing the efficiency of information exchange is proposed as a search for the rational location of a new node and the organization of such a set of its connections among the whole set of nodes of the computer network, which provides a minimum average topological distance. Mathematical models of effective topological organization of connections in computer network of power consumption control at the level of traction substations, electric power distances and the railway in general are proposed.

Analysis of Ro-La Transport Systems, Possibilities of Implementation in Romania

The paper brings to the fore the need for state support by making investments in railway infrastructure, in order to maintain and ensure the success of railway transport of trucks by introducing RO-LA transport in rail traffic. Using this mode of transport reduces the cost of maintaining road infrastructure, protects the environment, reduces fuel consumption, and reduces road traffic congestionRO-LA transport is an alternative solution to auto transport and contributes to the streamlining of traffic of goods and people.

Students of Railway College of the Town of Taiga in 1943–1991

The present article introduces a historical analysis of students of the Technical College of Taiga in 1943–1991. The socal analysis involved factorial, structural-systemic, and historical approaches. The Technical Railway College has almost 80 years of history, which makes it one of the leading educational institutions of its branch in the country. Since 1991, it has been the Taiga Institute of Railway Transport, a branch of the Omsk State Railway University. The author identified the changes in the contigent of applicants in 1943–1991. They appeared to be connected with the development of the country and education policy. The revealed characteristics made it possible to clarify the logic of the development of a particular institution based on the changes in the forms and methods of recruitment, payment, age, etc. In this regard, recruitment acted as a set of special methods, e.g.clubs of young naturalists, contests and conferences, material base, promotion of railway professions through alumni, etc. In addition, good working conditions and high salary were important factors that attracted people to the Technical College of Taiga.

Delay Management in Regional Railway Transport

This article is focused on the reliability of transfer connections in regional railway transport. The reliability of the transportation chain in public transport is an essential element for functional, attractive, and long-term sustainable public transport. This article discusses the causes and consequences of railway traffic disruption and related impacts on passenger transfer connections. To reduce the negative impacts of common operational disruptions, the authors present an original approach for determining transfer waiting times between delayed trains based on a modified critical path method (CPM). In addition, an example of the implementation of this method in regional railway transport in the Vysočina Region of the Czech Republic is provided.

Economic Spatial Structure in China: Evidence from Railway Transport Network

This study analyzes the structure of China’s overall railway transport network and its sub-networks of conventional railway and high-speed railway, with the aim to understand the country’s economic spatial structure that is reflected by or underlines the railway transport network. First, the results indicate that compared with developed cities, backward cities not only have fewer train services but also lack a symmetrical transport plan; backward cities tend to connect with developed cities rather than within themselves. Second, the national-level urban hierarchy was established using the proposed algorithm, which helped reveal the economic geography of three economic plates in China. Third, the law of the primate city is not prominent in a large country such as China, which is undergoing regional restructuring with the economic center of gravity shifting to the coastal area while also moving south.

Research on possibilities for monitoring stability of adjacent slopes to transport routes

Development of human society also implies modernization, respectively extension a road and railway transport structures. From this perspective, in order to achieve performance in the field of traffic safety, actions are also required to monitor the slopes, tailings dumps (active or greened) adjacent to transport routes where there are uncertainties regarding their stability. Ignoring stability and landslides can lead to loss of life, as well as significant material damage. Thus, the paper mainly addresses the issue of monitoring the slopes adjacent to road and rail transport routes where there are uncertainties regarding the control of landslides, as well as possibility of alerting before this occurs. From the multitude of possible solutions to be applied in the field, an equipment was developed and realized, which was experienced in real working conditions, and the results confirm validity of assumptions and certify the operation.
