One of the greatest challenges most developing countries are facing is the need to improve the transportation systems in their cities. In achieving this, emphasis has been put on the role of infrastructure development to improve the mobility of residents and reduce the negative externalities, such as traffic congestion, associated with most cities in both developed and developing countries. Hence, this study evaluates the impact traffic volume, in relation to available infrastructure capacity, has on traffic congestion, within the dynamics of a rapidly developing urban environment. Though there appears to be a consistent state of slow-moving traffic on two of the roads studied, traffic congestion is not critical, which suggests that available infrastructure is being appropriately utilized. This study found a statistically significant negative relationship between capacity utilization and traffic congestion levels.

Purpose: The aim of the study is to identify the essential attributes that determine the development of a sustainable, innovative and resistant to disruption transport infrastructure and to answer two research questions: How to shape models for the development of sustainable and innovative transport infrastructure, while maintaining the logistic continuity of mobility and transport systems? and What actions should organizations take in the conditions of permanent change in order to maintain operational efficiency and cost-effectiveness of implemented investments, not only thinking about the possible return of the pandemic, but also about increasingly difficult access to resources, climate change and social needs? Design/methodology/approach: The research methods and techniques used included, among others: content analysis, cause and effect analysis, selected methods of qualitative and quantitative analysis, which were used to present and discuss the results of the study. Findings: Searching for methods of operationalization of the implementation of the assumptions of the new development paradigm, a conceptual framework for the model of sustainable development of transport infrastructure was developed. EU programs and instruments supporting the financing of activities in the field of development of sustainable, innovative and resilient transport infrastructure were reviewed. Attributes were indicated so that the development would strive for the simultaneous implementation of economic, social and environmental goals. Research limitations/implications: The study did not measure the sustainability of infrastructure investments in transport. The precondition for successfully performing such a task is the availability of an accurate data set and the selection of appropriate measurement indicators. This has implications for future research. Practical implications: One of the key challenges in cities is making decisions about investments in the development of economically effective, environmentally safe and socially important transport infrastructure. Hence, the development of algorithmic approaches that allow the use of the proposed qualitative model may contribute to improving the efficiency in making investment decisions.Originality/value: The originality of the conducted research was achieved through its measurable character. The proposed model can contribute to the improvement of decision-making tools in the field of allocation of public and other funds for investments, so that they contribute to the sustainability of mobility systems.

The integration of Ukraine’s economy into the European space requires the dynamic and balanced development of all its sectors, especially the transport sector. The purpose of the research is to identify the factors related to transport entrepreneurship that affect the economic development of Ukraine, in particular regarding the formation of added value (gross regional product). The paper presents the author’s definition of transport entrepreneurship as an independent, systematic, and risky entrepreneurial activity in providing transport services. The results revealed a negative trend in the formation of the added value of the transport enterprises of Ukraine, both in terms of value and as a percentage of GDP. This prompted the authors to determine the factors affecting the formation of gross added value (gross regional product) by transport enterprises of Ukraine to further develop proposals aimed at their activation. Four models were created in the first stage of the research to achieve the goal. These models are based on gross regional product in transport, warehousing, postal and courier activities; gross regional product in transport, warehousing, and postal and courier activities per capita; gross value added in transport, warehousing, and postal and courier activities; and gross value added in transport, warehousing, and postal and courier activities per capita. In the second stage of the research, the fifth model with the highest correlation coefficients was built, which made it possible to identify the factors of negative and positive influence on the formation of gross added value (gross regional product) by transport enterprises in Ukraine. Based on the results, a number of measures are proposed to stimulate factors of positive influence and neutralize negative influence. The proposed tools for identifying the factors related to transport entrepreneurship that affect the economic development of Ukraine can serve as markers for the formation of the country’s post-war strategy in the field of transport entrepreneurship.

In the article publications have been analyzed and summarized on this topic: studied the experience of implementing building information models and geographic information models for administrative and economic management of transport infrastructure facilities on the example of the regional airport activity. After the stage of collecting geospatial data from various sources and sensors, the data is imported into CAD-systems or GIS-systems. Different software products are used to work with both of these models. The processes of data organization in the process of creating building information models and geographic information models differ to some extent. The issues of integration of such models are not yet fully addressed and need to be addressed. In the process of integration of spatial data, solutions to the integration of semantics, topology, formats and standards of geospatial data are needed. An important task is to develop and study the experience of creating software modules that allow you to integrate BIM-models into geographic information systems. Based on the research, it is established that the current area of research is the development of technologies that allow the generation of information from BIM and GIS to create a more interconnected infrastructure. The integration of BIM and GIS information to create a spatial data infrastructure (SDI) is a perspective direction.

The problems of modern urban planning are described and ways to solve these are discussed. Cities of the Russian Federation have low indicators of transport and planning efficiency; the general plan theory of the city does not answer many questions on the development of the urban environment. There are no requirements for the efficient use of urban areas and the formation of a city plan. An integrated approach is considered to improve the productivity of transport infrastructure to the modern level of motorization, develop measures to improve road safety, and also enable the prioritized development of environmentally friendly, economical, and high-speed types of public passenger transport. In this respect, the problems of improving the theory and practice of urban planning are highlighted in a new light. During the period of preparation of this article for publication, a new master plan for the development of the city of Omsk was approved, which included these proposals. The construction of the longest embankment in Eurasia began; a decision was made to use tunnels and stations of the unfinished metro for the development of tram routes.

This article examines the link between logistics indicators and economic growth in Kazakhstan in the period 1995-2019. Factors and the causal relationship between the indicators of transport development and economic growth, using the models of total production, demand and vector error correction, are studied. The analysis established specifics of the relationship between indicators of various types of transport and economic growth and their mutual influence, both in terms of directions and the nature of the relationship. A bi-directional cause-and-effect relationship between railway transport infrastructure and economic growth has been identified according to the Granger test. It was found that in a small economy, road and sea transport in the long term will lead to a higher rate of economic growth, and vice versa, economic growth encourages the development of pipeline transport and this in turn, in a one-way direction, stimulates the development of all other types of transport. It was revealed that economic growth in Kazakhstan leads to an increase in demand for transport and logistics services and their infrastructure to a lesser extent than in countries with large economies. To improve the effectiveness of the economy, a differentiated approach to transport policy is recommended depending on the highlighted long-term relationship between the studied parameters. Our research indicates that conditions for road and sea transport in Kazakhstan should be improved to stimulate economic growth. The results of the study can be used as recommendations for developing a long-term transport policy.

This article discusses the issue of seaport competitiveness. This is one of the most important issues in port studies. Conducting a port competitiveness analysis focuses on comparing components of port competitiveness for selected ports or terminals. First, a comparative analysis of selected seaports was performed in the article, followed by a detailed analysis of selected terminals in indicated ports. The main purpose of the article is to assess the effect of the new investment in the seaport in the town of Police (the construction of the railway connection with the national network) on its competitive position in relation to seaports in the immediate vicinity. To achieve the assumed goal, the following research methods were used: literature review, documentary method, linear weighting method, and variant analysis. The areas covered by the research study are selective seaports in Zachodniopomorskie Voivodeship (Szczecin, Świnoujście, and Police), Poland. Based on the research studies completed so far, it was shown that connecting a seaport with the national rail network may be a significant factor affecting the port’s competitiveness in relation to the ports located in the direct vicinity.

Land-sea transport chains constitute a key part of the Europe’s economy, as a significant part of its trade is carried out using sea transport. Transport, storage, or delivery processes carried out within these chains are characterized by specified economic and technical efficiency, which often does not take into consideration the external costs these processes generate. Therefore, there is a need for further changes in the European land-sea transport chains, the aim of which should be a further reduction of the negative influence of transport on the society and the environment, in accordance with the assumptions adopted under the EU's sustainable development policy. The article examines the land-sea freight transport chains in terms of the EU's sustainable development goals on the example of Zachodniopomorskie Voivodeship (ZV), Poland. The region was selected owing to two key factors. First, the transport chains across the region are typical for many European areas. Second, the region itself has experienced intensive development of the Transport, Shipping and Logistics (TSL) sector and a numer of changes in freight flows for several years. The main goal of the article was to identify the possibility of reducing external costs resulting from the use of combined transport solutions in ZV. Two case studies were analyzed for this purpose. In both of them, the assumed effect was the reduction of external costs of freight transport in ZV. The potential reduction of external costs generated by cargo transport in ZV was estimated on the basis of the European methodology in terms of the amount of external costs generated by individual modes and means of transport. The research showed that the implementation of combined transport in ZV can bring measurable benefits to the region. The analyses also allowed for the identification of technical and organizational activities that are crucial for ZV and make it possible to reduce negative transport effects.

In transportation engineering, earthwork is the main structural material which geotechnical properties can be positively modified with admixtures. This article focuses on the application of energy by-products in earthwork of transportation line structures and summarizes their advantages and define the scope of their utilization. Earthwork construction demands the considerable volume of quality material and therefore, the effort to optimize traditional material substitution is made. One possibility is to apply solid by-products emerging when combusting coal, which is referred to as secondary energy products. These include various types of fly-ash, slag, bottom ash or gypsum. Requisite for their further widespread utilization is the application in the construction and modernization of transport infrastructure, including road and rail construction, or in the case of flood control dams within the framework of water management measures against flooding. They can be utilized also as municipal waste dumps covering. However, the application of fly ashes in earthwork constructions delivers certain limits. When contacting with rain ingress or groundwater, the leaching containing heavy and toxic metals depending on energy by-product type may occur. Alternatively, the limitation of their application can be relatively low mechanical resistance to cyclic saturation and frost effect and consequent volume changes. This article deals with long-term observation results of the energy by-products saturation and additivity influence on volume changes. For the investigation purpose of failure causes, the phase composition using X-ray crystallography and Raman spectroscopy was determined.

W inżynierii transportu masy ziemne są głównym materiałem konstrukcyjnym, którego właściwości geotechniczne można pozytywnie modyfikować za pomocą domieszek. Artykuł koncentruje się na zastosowaniu produktów ubocznych spalania w pracach ziemnych w konstrukcji linii transportowych ocenia ich zalety oraz określa zakres ich wykorzystania. Konstrukcja robót ziemnych wymaga znacznej ilości wysokiej jakości materiału, dlatego podejmowane są wysiłki w celu optymalizacji zastępowania materiałów. Jedną z możliwości jest zastosowanie stałych ubocznych produktów spalania węgla, które są określane jako wtórne produkty energetyczne. Należą do nich różne rodzaje popiołów lotnych, żużli, popiołów dennych lub gipsu. Kierunkiem ich wykorzystania jest zastosowanie w budowie i modernizacji infrastruktury transportowej, w tym w budownictwie drogowym, kolejowym, budowie zapór przeciwpowodziowych. Zastosowanie popiołów lotnych w konstrukcjach ziemnych ma jednak pewne ograniczenia. Podczas kontaktu z wnikającymi deszczami lub wodami gruntowymi może wystąpić ługowanie metali ciężkich i toksycznych w zależności od składu ubocznego produktu spalania. Ograniczeniem ich zastosowania może być względnie niska odporność mechaniczna i mrozoodporność. Artykuł dotyczy wyników długoterminowych obserwacji dodatku ubocznych produktów spalania na zmiany objętości. Skład fazowy określono za pomocą krystalografii rentgenowskiej i spektroskopii Ramana.

W artykule przedstawiono nowe narzędzie optymalizacyjne wspierające zarządzanie łańcuchem dostaw w aspekcie wielokryterialnym. To narzędzie zostało wdrożone w systemie EPLOS (Europejski Portal Usług Logistycznych). System EPLOS to zintegrowany system informatyczny wspierający proces tworzenia sieci dostaw i dystrybucji w łańcuchach dostaw. Ten system składa się z wielu modułów, np. moduł optymalizacji odpowiedzialny za przetwarzanie danych, generowanie wyników, moduł danych wejściowych, moduł kalibracji parametrów algorytmu optymalizacyjnego. Głównym celem badań było opracowanie systemu do określania parametrów łańcucha dostaw, które wpływają na jego efektywność w procesie zarządzania przepływem towarów między poszczególnymi ogniwami łańcucha. Parametry te zostały uwzględnione w modelu matematycznym jako zmienne decyzyjne w celu ustalenia ich w procesie optymalizacji. W modelu matematycznym zdefiniowano dane wejściowe adekwatne do analizowanego problemu, przedstawiono główne ograniczenia związane z wyznaczaniem efektywnego sposobu zarządzania łańcuchem dostaw oraz opisano funkcje kryterium. Problem zarządzania przepływem towarów w łańcuchu dostaw został przedstawiony w ujęciu wielokryterialnym. Ocenę efektywności zarządzania łańcuchem dostaw przeprowadzono na podstawie globalnej funkcji kryterium składającej się z częściowych funkcji kryteriów opisanych w modelu matematycznym. Główne funkcje kryteriów na podstawie których wyznaczane jest końcowe rozwiązane to współczynnik wykorzystania wewnętrznych środków transportu, współczynnik wykorzystania zewnętrznych środków transportu, koszty pracy środków transportu wewnętrznego i personelu, całkowity koszt realizacji zadań transportowych, współczynnik wykorzystania czasu zaangażowania pojazdów, całkowity czas poświęcony na wykonanie zadań, czy liczba pojazdów. Punktem wyjścia do badania było założenie, że o skuteczności zarządzania łańcuchem decydują dwa problemy decyzyjne ważne dla menedżerów w procesie zarządzania łańcuchem dostaw, tj. problem przydziału pojazdów do zadań i problem lokalizacji obiektów logistycznych w łańcuchu dostaw. Aby rozwiązać badany problem, zaproponowano innowacyjne podejście w postaci opracowania algorytmu genetycznego, który został dostosowane do przedstawionego modelu matematycznego. W pracy szczegółowo opisano poszczególne kroki konstruowania algorytmu. Zaproponowana struktura przetwarzana przez algorytm jest strukturą macierzową, dzięki której wyznaczane są optymalne parametry łańcucha dostaw. Procesy krzyżowania i mutacji zostały opracowane adekwatnie do przyjętej struktury macierzowej. W procesie kalibracji algorytmu wyznaczono takie wartości parametrów algorytmu tj. prawdopodobieństwo krzyżowania czy mutacji, które generują optymalne rozwiązanie. Poprawność algorytmu genetycznego oraz efektywność zaproponowanego narzędzia wspomagającego proces zarządzania łańcuchem dostaw została potwierdzona w procesie jego weryfikacji.

The article presents a new optimization tool supporting supply chain management in the multi-criteria aspect. This tool was implemented in the EPLOS system (European Logistics Services Portal system). The EPLOS system is an integrated IT system supporting the process of creating a supply and distribution network in supply chains. This system consists of many modules e.g. optimization module which are responsible for data processing, generating results. The main objective of the research was to develop a system to determine the parameters of the supply chain, which affect its efficiency in the process of managing the goods flow between individual links in the chain. These parameters were taken into account in the mathematical model as decision variables in order to determine them in the optimization process. The assessment of supply chain management effectiveness was carried out on the basis of the global function of the criterion consisting of partial functions of the criteria described in the mathematical model. The starting point for the study was the assumption that the effectiveness of chain management is determined by two important decision-making problems that are important for managers in the supply chain management process, i.e. the problem of assigning vehicles to tasks and the problem of locating logistics facilities in the supply chain. In order to solve the problem, an innovative approach to the genetic algorithm was proposed, which was adapted to the developed mathematical model. The correctness of the genetic algorithm has been confirmed in the process of its verification.
