The necessary activities that contribute to maintaining good operational condition of the railway transport line also include the diagnostics of track length. Diagnostics of railway tracks is most often performed by means of regular visual inspection (in the conditions of the infrastructure manager – ŽSR). The objective of the article is to provide information on the application of a new approach to diagnostics of the technical condition of railway infrastructure. The new approach to defect identification on railway infrastructure uses non-invasive diagnostic methods based on the latest knowledge in the field of information and communication technologies. These facts resulted in investigating the possibilities of automatic detection of the technical condition of the track length using neural networks. The article is part of the following scientific research task: ‘Research into new knowledge and observational experience of a new generation of diagnostic systems in industrial production and transport industry – research into the physical nature of an automated track length video inspection system’, supported by the Ministry of Education, Science, Research and Sport of the Slovak Republic.</p> </abstract>ARTICLE2022-05-12T00:00:00.000+00:00Current Perspectives on Development of Industry 4.0 in Logistics of Machinery and Equipment Industry in Slovakia<abstract> <title style='display:none'>Abstract</title> <p>The aim of the paper was to evaluate the current situation of Industry 4.0 in logistics in the machinery and equipment industry in Slovakia.

In practice, it has become a complement to the public transport system in large cities, and above all in the most crowded city centers. Importantly, the solution, which is a city bike, can contribute to the reduction of urban congestion, air pollution and to the reduction of noise levels. The paper discusses the issue of city bike system functioning in terms of meeting the transport needs in the area of the city of Lublin. The aim of the work is to describe the city bike system and to indicate the conditions for choosing this means of transport among the inhabitants of the Lublin region. A survey conducted among respondents in 2020 was used. The paper presents own research results and expectations of potential users of this system in the context of displacements, as well as the impact of the Covid-19 pandemic on the system functioning in 2020, and the strategy for operating this industry.</p> </abstract>ARTICLE2022-05-12T00:00:00.000+00:00Influence of Cruise Control Use on Vehicle´s Consumption<abstract> <title style='display:none'>Abstract</title> <p>Most vehicles used in road transport are powered by internal combustion engines. Depending on the nature of their operation, each vehicle releases a certain amount of emissions into the air. Among other things, emissions include carbon dioxide, which significantly contributes to the greenhouse effect. The quantity of CO2 produced is closely related to fuel consumption. The article presents the results of test drives which were performed on a passenger car meeting emission standard Euro 4. The aim of the study was to verify the impact of the use of cruise control on fuel consumption of the vehicle. The measurement was performed on the basis of test drives carried out on a highway section. The consumption was determined based on the data obtained from a diagnostic device, which was connected to the vehicle via OBD. The test drives were repeated several times in order to get as close as possible to the actual operation of the vehicle.</p> </abstract>ARTICLE2021-05-24T00:00:00.000+00:00Organization of Urban Transport Organization – Presentation of Bicycle System and Bicycle Infrastructure in Lublin<abstract> <title style='display:none'>Abstract</title> <p>The introduction of a city bike system, which has become a complement to the public transport system in large cities and mainly in the most crowded city centers, seems to be a very good solution, which may contribute to reducing urban congestion, air pollution, and noise level. In many situations, bicycle transport can solve the deficiencies in public transport, e.g. at nights, during holidays and on days when bus services are operated to a limited extent. The article presents the functioning of the city bike system in Lublin implemented at the end of 2014, including basic information on the system, its advantages and disadvantages, as well as the existing infrastructure and development prospects.</p> </abstract>ARTICLE2021-05-28T00:00:00.000+00:00Supply Chain Management and Logistics Big Data Challenges in Bulgaria<abstract> <title style='display:none'>Abstract</title> <p>The article focuses on the challenges of applying big data approaches to logistics and supply chain management in Bulgaria, while also presenting the challenges, opportunities and problems from a broader perspective.

The research is based on an analysis of the situation in B2B implementation during the period of the 2008-2009 economic crisis, where – on a sample of 229 logistic companies based in the Czech Republic – it ascertains whether the extent of B2B implementation changed over this period. This is done in a short-time (2006 vs. 2010) as well as long-time (extended with 2014 vs. 2018) horizon. Although some conclusions are in contradiction with other authors, they state a high extent of B2B implementation, which even further increased over the above economic crisis and even continued in a longer time horizon following the crisis. The conclusions are then analogically transferred to the present 2020 “coronavirus economic recession” and practicable recommendations are formulated. Being made on a high level of reliability, the recommendations have a potential to serve as an efficient tool ensuring economic “survival” of logistic companies, which is – especially in the field of logistics due to the implemented anti-COVID measures creating new trade barriers – very actual.</p> </abstract>ARTICLE2021-05-24T00:00:00.000+00:00Effect Size of Logistics: Evidence from Selected Countries<abstract> <title style='display:none'>Abstract</title> <p>Efficiency of cross-border goods' movement and resource use is key for countries' economic growth. This study aimed to estimate the effect size of transportation infrastructure and logistics performance on selected countries' development, based on the infrastructure of services approach. A partial least square (PLS) and structural equation modeling (SEM) analysis for 74 countries for 2012–2018 revealed that transportation infrastructure and logistics performance were statistically significant (at the 1% level) for economic development, despite small and medium effect size. Transportation had a significantly positive and large effect on logistics performance (at the 1% level). Mediation analysis results also showed evidence of the significantly large effect size (at the 1% level) of logistics performance. The study concludes that logistics performance is a strong contributor—directly and indirectly—in the development of countries where transportation alone may not be enough. Hence, countries should prioritize logistics development strategies to harness global production networks, improve policies and practices, and enhance their standards of living.</p> </abstract>ARTICLE2021-06-28T00:00:00.000+00:00Determinant Port-related Factors Affecting the Flow of Shipping Trade and Logistics in Nigerian Seaports<abstract> <title style='display:none'>Abstract</title> <p>The need to eliminate bottlenecks to port operations in Nigeria was a fundamental goal of the port privatization about 2 decades ago. Current trends in ports management; however, suggest existence of numerous inefficiency challenges reflected in long ship turnaround time, increasing trend of cargo dwell time, high cargo pilferage risk rate, poor condition of port infrastructure and superstructure, multiple charges and government agencies, cumbersome cargo clearance &amp; examination procedures, port congestion related delays particularly in Apapa and Onne ports, etc. The study identifies the decisive port-related factors constraining the flow of shipping trade in Nigerian ports using a survey to obtain data on the influence of the identified factors on the flow of shipping trade in Nigerian ports. The Principal Component Analysis (PCA) was used to analyze the data obtained. The results indicate that high cargo pilferage risk profile, long ship turnaround time and increasing trend of cargo dwell time constitute the significant port-related factors constraining the flow of shipping in Nigerian ports. It can be concluded that terminal operators should prioritize solutions to the problems of high cargo pilferage risk profile, long ship turnaround time and increasing cargo dwell time, which constitute the major constraints to the flow of shipping trade.</p> </abstract>ARTICLE2021-12-17T00:00:00.000+00:00Evaluation and Selection of Nigerian Third-Party Logistics Service Providers Using Multi-Criteria Decision Models<abstract> <title style='display:none'>Abstract</title> <p>This paper is focused on solving the evaluation and selection of 3PL’s by applying multi-criteria decision-making methods. Nigerian Breweries, Nigerian Bottling Company (NBC), AG Leventis, Kobo logistics, and Flour Mills of Nigeria (FMN) were understudied. The main criteria on which evaluation is based were established: Cost, Service level, Financial Capability, Reputation and Long-term relationship. A combination of two quantitative models was adopted in the study. Relevant data were collected through an oral interview with managers and key decision-makers at the companies. SWARA was first applied to the collated data to determine the relative weights of the criteria. Afterwards, the TOPSIS was applied to the weights developed using SWARA and on the performance of the selected service providers. After the analysis, the best service provider was identified as supplier 2 while the worst was supplier 5.</p> </abstract>ARTICLE2021-06-28T00:00:00.000+00:00Assessing the Energy Intensity and Greenhouse Gas Emissions of the Traffic Services in a Selected Region<abstract> <title style='display:none'>Abstract</title> <p>The consumption of internal combustion vehicles and the resulting emissions associated with their operation have been at the forefront in the development of the automotive industry in recent years. This development is supported and required by a number of public administration organizations. This research deals with the monitoring of selected parameters for different types of means of transport, while the unifying element is consumption and emissions per passenger. The aim of the research is to determine the optimal vehicle for passenger transport for selected transport between two specific cities in Slovakia, Europe. The research used methods of analysis of energy intensity and emissions of individual transport units, while fuel consumption in a particular transport relationship is a decisive evaluation factor, which includes the calculation of experimental measurements in a real traffic situation. The various data and diagrams provide relevant data on the fuel consumption values achieved by the experiment converted to fuel consumption. The research is given as an example, and its principle can be applied in other specific localities. it can be applied to others, they may also apply to other transport routes.</p> </abstract>ARTICLE2021-05-24T00:00:00.000+00:00Analysis of Airport Operational Performance in Selected Airports of Northern Nigeria<abstract> <title style='display:none'>Abstract</title> <p>This study focuses on the overall airport operational performance of selected airports in Northern Nigeria using the stochastic Frontier Analysis (SFA) model.

Logistics operations in smart companies need to be not only properly set up, but also properly controlled and improved. The purpose of the article is to analyze the controlling environment in a selected company and point out possible improvements in logistics activities and devices, with a view to preventing different types of problems. For this purpose, observations of the internal logistics processes in a selected company were used and quantified to assess its internal state. On the basis of the data, controlling measures are put forward to improve the management of the company’s logistics activities. The results of the research highlight the opportunities that exist through controlling activities to collect and analyze information about the logistics activities of a company. By doing so, employees can be given greater responsibility for the fulfilment of their tasks and contribute to the streamlining of logistics processes. For managers, the implementation of controlling represents a change in the way of thinking and managing a company.</p> </abstract>ARTICLE2021-11-25T00:00:00.000+00:00External Debt, External Reserves, Debt Service Costs and Economic Growth: Implications for the Nigerian Transport Sector<abstract> <title style='display:none'>Abstract</title> <p>The objective of the study presented in this article is to examine the relationship between external debt (EXDT), external reserves (EXRS), total debt service costs (TDS) and Nigeria’s economic growth (RGDP) and how these variables impact on the Nigerian transport economy employing profligacy theory. The study used secondary data for Nigeria for the period 1979 to 2019 obtained from the International Debt Office (WBG). The econometric techniques used include OLS, Granger causality and Engle-Granger cointegration at a 0.05 confidence level. The results show that EXDT has a statistically significant negative relationship with EXRS, with no statistically significant relationship existing with RGDP and TDS in the short term. All the variables showed significant cointegration over the long term, with the conclusion that the relationship between EXRS and EXDT is negatively significant in the short term, while the other variables are insignificant. The recommendations of the study include, that the government and monetary authorities should endeavour to reduce the creation of foreign debt for nonreproductive projects in key sectors due to its adverse effect on external reserves, and instead pursue aid, grants and domestic long-term loan options necessary for effective growth of the transport and other key sectors of the economy.</p> </abstract>ARTICLE2021-11-23T00:00:00.000+00:00Design of Automatic Assembly Station for Industrial Vehicles Parts<abstract> <title style='display:none'>Abstract</title> <p>Automated production and assembly lines can be considered a crucial factor in accelerating the production processes and achieving the maximum financial savings. In particular, specialized single-purpose machines can significantly reduce production or assembly time. The submitted article presents a design of a single-purpose device that is used for the automated assembly of a roller bush with a screw. These components are then used for construction and agricultural vehicles to attach other components. Naturally, the design of this specific device is more demanding in terms of time consumption, precision, detail and initial investment than similar less complicated all-purpose devices. Nevertheless, single-purpose devices turn out to be a better option in the sense of quality and profit both in the long-term and high-capacity projects, such as automotive industry, agricultural and construction machinery. The best alternative was selected from several proposals using the evaluation method. The assembly machine was designed and optimized using Computer Aided Design systems and Finite Element Method analyses. The resulting equipment was used in practice, where it significantly increased the productivity and production efficiency.</p> </abstract>ARTICLE2021-11-28T00:00:00.000+00:00Use of Technological Diagnosis in Rail Vehicle Engines Maintenance<abstract> <title style='display:none'>Abstract</title> <p>The paper aims to classify the maintenance of internal combustion engines in 812 series diesel multiple units, to analyse operating failures, and to identify methods and procedures for determining their current mechanical condition. The paper specifies the required procedures and methods for maintenance starting from the development of the DMU (diesel multiple units) 812 series to the present. It also focuses on understanding how diagnosis and control sensors are attached in individual cable harnesses. A protocol for diagnosing combustion engine defects is proposed in the final part of the paper. A part of the paper is a proposed list of codes for individual faults to facilitate the work.

Faults leading to engine stop are identified.</p> </abstract>ARTICLE2021-12-04T00:00:00.000+00:00Evaluation of the Hazard Perception Skills of Young Drivers<abstract> <title style='display:none'>Abstract</title> <p>The aim of this study is to collate valuable information about the hazard perception process of (young) drivers and to evaluate their hazard perception skills. For this, an eye-tracking system was used to record the visual behaviour of drivers. In addition, a system based on a data logger and sensors was developed to capture and log the relevant data from the vehicle. By tapping into the vehiclés CAN bus (Controller Area Network), the needed parameters (e.g. position of accelerator, brake, and clutch pedal, as well as the steering wheel angle) were acquired through the reverse engineering of the vehicle′s CAN stream. All the captured data was subsequently synchronized and overlaid in the eye-tracking video. The complete system, i.e. data-logger and sensors, was consistently integrated into a driving school car. Due to the fact that all the data was captured in real-time whilst driving in traffic, every analysed situation can be considered unique and therefore cannot be compared to other situations. The results of the study revealed that only in 18% of the analysed situations, the hazard-perception skills were adequate or the same as they were taught at the driving school just a few months previous. Confronted by the videos of their lessons, the participating drivers adjusted their self-assessment scores for their driving skills downwards by around 25% on average.</p> </abstract>ARTICLE2021-06-04T00:00:00.000+00:00Sustainable Transport Packaging: Evaluation and Feasibility for Different Use Cases<abstract> <title style='display:none'>Abstract</title> <p>The continuous increase in e-commerce shipping is causing a critical amount of transport packaging waste. The aim of this paper is a comprehensive presentation of different types of innovations for sustainable transport packaging. Within the paper, classification and evaluation of 37 sustainable packaging solutions are presented, including customized on-demand packaging, alternative materials and closed-loop systems. A multi-criteria evaluation scheme covering a wide range of economic, ecological, operational and social indicators was used to assess the feasibility of the packaging options in different cases. Depending on the degree of innovation and implementation risk, packaging options are proposed as a “Quick Win”, “Go Green” or “Thought Leadership” solution. In the conclusion chapter of this paper, recommendations are made for three different use cases, namely grocery, fashion and textiles and electronic goods.</p> </abstract>ARTICLE2021-11-06T00:00:00.000+00:00en-us-1
