Regulation and proper coordination of transport is conditioned by sufficient input data. The sensor network ranks among the resources that provide an overview of operation in road traffic. The city of Žilina was chosen to support the building of a sensory network with applied research of available data with subsequent use in practice. The sensor network offers a database for the subsequent evaluation of inputs from several points of view. The COVID-19 pandemic was associated with restrictions and many block measures that changed the dynamics of traffic journeys. The aim of this paper was to evaluate traffic flow deviations in connection with the continuation of the third wave of the COVID-19 pandemic.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ttt-2023-00052023-05-24T00:00:00.000+00:00https://sciendo.com/article/10.2478/ttt-2023-0006<abstract> <title style='display:none'>Abstract</title> <p>Rail transport is a continuous process that must be coordinated at all levels of management and is determined by technological processes. From a technological point of view, it is important to correctly determine the practical throughput of the track section, also called the railway infrastructure capacity. This means how much train traffic can be used to load the track section so that it shows sufficient train traffic stability even in the event of operational irregularities. The article is focused on the method of increasing the capacity of the Drienovská Nová Ves - Kysak track section with using the application of the method of determining the practical throughput performance in the anticipated timetable. Detailed determination of the occupation times of the section in the current state and in the application of individual proposals to increase the capacity of the investigated railway line provide us with information on other possibilities of modernization of the railway infrastructure in Slovak Republic. The article describes and evaluates the advantages and disadvantages of individual proposals to increase capacity of the track section. As part of the future modernization of the railway infrastructure of this track section, it is necessary to implement these measures, as the track section under investigation is part of the AGTC and TEN-T international railway corridors. When designing new corridors, it is necessary to analyse and optimize the current railway network. The intention is not only to increase the quality of railway infrastructure, but also the quality of goods and passenger transport.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ttt-2023-00062023-05-24T00:00:00.000+00:00https://sciendo.com/article/10.2478/ttt-2023-0002<abstract> <title style='display:none'>Abstract</title> <p>During the individual waves of the COVID-19 pandemic, several areas have been significantly changed in our society. Especially during its first wave in the spring of 2020, lockdowns began to be introduced practically overnight and several strict anti-pandemic measures were adopted in most countries of the world, which changed the lives of all residents. The mentioned changes also significantly affected the public passenger transport sector and the transport process. Many times, they were implemented into practice immediately without conceptual systematic preparation. This contribution is focused on a progressive proposal of measures to improve the quality and efficiency of the transport process in railway passenger transport in the next potential period of the pandemic. In the process of providing a passenger with a travel document during the pandemic, new technical and technological elements are implemented in railway stations and trains to reduce the risk of virus transmission in order to protect the health of the passenger and the carrier’s employees. By introducing more modern passenger equipment systems in railway passenger transport in the form of automation and digitization of processes, it is possible to streamline and improve the quality of the transport process.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ttt-2023-00022023-05-24T00:00:00.000+00:00https://sciendo.com/article/10.2478/ttt-2023-0004<abstract> <title style='display:none'>Abstract</title> <p>The contribution is focused on the analysis of the current state and development of traffic service in international rail passenger transport between Slovakia and the Czech Republic. The current situation in the post-covid period is analysed in more detail from several points of view.

Part of the analysis of the work is a proposal for ways to improve the current traffic service at individual border crossings in international rail transport.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ttt-2023-00042023-05-24T00:00:00.000+00:00https://sciendo.com/article/10.2478/ttt-2023-0001<abstract> <title style='display:none'>Abstract</title> <p>In a pandemic situation such as Covid-19, it is essential to keep contact to a minimum, but it is also important to maintain an acceptable supply level to the population. This paper presents a general analysis of selected exponential logistics technologies, particularly the possibilities of their use in the implementation of logistics chains, or the segment related to storage and distribution during a pandemic. Exponential technologies are those whose performance doubles yearly, but whose cost is halved. Five logistics technologies have been selected that meet the exponentiality criteria and can address pandemic-related issues under certain conditions. Each of these technologies can be used in specific segments of logistics systems. The technologies meet the exponentiation criterion and contribute to increased performance, efficiency, and process automation These technologies are becoming part of a new approach to logistics and are directly related to the advent of Industry 4.0. This paper analysis and subsequent application concern logistics technologies such as internet of things, automated guided vehicles, drones, digital twins, and artificial intelligence.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ttt-2023-00012023-05-24T00:00:00.000+00:00https://sciendo.com/article/10.2478/ttt-2023-0003<abstract> <title style='display:none'>Abstract</title> <p>The COVID 19 pandemic has created blocks in our society that have affected all areas of our lives. One of the areas that have been affected most significantly is the transport sector. Due to the restrictions against the spread of the pandemic, public transport suffered huge losses. The aim of this contribution is to point out the changes in the traffic behavior of the inhabitants of Slovakia due to the COVID-19 pandemic. For this purpose, the data obtained using a questionnaire survey, which was carried out during 2021 by the inhabitants of Slovakia, served this purpose. It was found that during the strongest waves of the pandemic, residents avoided using public transport and switched to other modes of transport, primarily individual car and pedestrian transport. The main reason was safety and health concerns.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ttt-2023-00032023-05-24T00:00:00.000+00:00https://sciendo.com/article/10.2478/ttt-2022-0009<abstract> <title style='display:none'>Abstract</title> <p>Railway undertakings face many challenges and obstacles to competition in the transport market. Strategic management methods in relation to quality assurance of services provided by carriers, used not only in transport sectors but also in industrial sectors, are a way to continuously improve the quality of services and thus the competitiveness of railway undertakings. Nowadays, customers are becoming more and more demanding, also in view of the wider range of services offered by other modes of transport. For this reason, quality requirements are increasing. Most business strategy evaluation systems are only partial, limiting themselves to the assessment of certain factors where many shortcomings remain hidden. In the same way, a strategic plan for the economic growth and development of a transport organisation does not always ensure the achievement of the set objectives.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ttt-2022-00092023-01-19T00:00:00.000+00:00https://sciendo.com/article/10.2478/ttt-2022-0007<abstract> <title style='display:none'>Abstract</title> <p>At present, in business practice, we meet the requirements of the employer for employees to work better, faster and better in order to satisfy the customer as much as possible. It often happens that this requirement on the part of the employer is evaluated subjectively and then subsequently the presentation of the results of the employees’ work is not objective. Several methods can be used to improve the evaluation process, and in our case we used an evaluation system using a full-fledged feedback methodology.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ttt-2022-00072023-01-19T00:00:00.000+00:00https://sciendo.com/article/10.2478/ttt-2022-0006<abstract> <title style='display:none'>Abstract</title> <p>Simulation is one of the methods in which a real system is substituted with a computer model where experiments are practiced and then subsequently analyzed and evaluated. After the application of the results of simulation and verification of its effects the results are applied in the real system with the aim to optimize processes. It seems that simulation is appropriate tool which offers all useful information about how model system works in given conditions. Simulation in planning and optimizing allows better and faster understanding of processes and guarantees that operational devices will work at the top of their effectiveness. Simulation plays an important role in optimization of logistic chains organization. There is a need to analyze strictly, find narrow places, remove them and consequently to repeat simulation with the new data. It is also very profitable to parallelly simulate more possible alternatives when there is a change in input data and consequently to compare them. The model of logistic chain created by simulation will considerably influence right decisions in process solving related to distribution. Subsequent optimization of logistic chain management can be aimed at the organization where the sum of final costs for transport and warehousing is minimum in compliance with basic parameters of customers’ service level.</p> <p>In the paper classic systems of the management of logistic chains are compared, namely direct distribution and indirect distribution made by technology Cross-Dock canter. Final comparative analysis of both systems simulation points out not only to their advantages and disadvantages but also to the possibilities of their optimization and application in particular operational conditions.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ttt-2022-00062023-01-19T00:00:00.000+00:00https://sciendo.com/article/10.2478/ttt-2022-0011<abstract> <title style='display:none'>Abstract</title> <p>We currently rank road transport as one of the largest producers of harmful substances. In relation to the environment, we can say that it is a source of emissions, vibrations, and, last but not least, noise. Transport (especially road) puts pressure on land and contributes greatly to global environmental problems. Especially in road transport, a large number of accidents occur, which are reflected in material and especially human losses, as well as in congestion, which manifests itself in the loss of time. Global production of pollutant emissions is associated with the development of transport, an increase in transport performance, and fuel consumption. The Ministry of Transport considers it one of the largest in terms of the number of emissions produced. Today, a lot of attention is paid to ecology and especially to air quality. This article talks about the extent to which transport can adjust air quality and how difficult it is to prevent the number of emissions produced. Several actions and different methods are needed to answer these questions. The basis is the creation of a unified system of product production evaluation in the entire monitored area.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ttt-2022-00112023-01-19T00:00:00.000+00:00https://sciendo.com/article/10.2478/ttt-2022-0010<abstract> <title style='display:none'>Abstract</title> <p>The operation of railway passenger transport is characterized by high economic costs and also high requirements for personnel and vehicle means. Existing rail transport operators aim to provide transport services as modern, efficient and cost-effective as possible, while meeting all safety and quality standards. In the case of public service obligations, they must also respect the requirements of the contracts. Currently, a significant transformation of the railway passenger transport operation throughout Slovakia is being prepared in order to increase its efficiency, sustainability and quality. This primarily concerns public service obligations. The line Košice - Prešov - Lipany - Plaveč - (Muszyna) (line No 188) will also be affected. Transport services on this line will be significantly modified and intensified, inter alia, because of the introduction of an integrated transport system in the relevant region. The Route 188 service plans were prepared in two different Transport Service Plans (TSPs). The first one was prepared by the Prešov and Košice Regions. In parallel with the first TSP, a second TSP was prepared by the Ministry of Transport and Construction of the Slovak Republic (MT&amp;C SR) for the entire Slovak railway network, which also includes line No 188. There are several differences in the proposlas included in TSPs for the line in question. The main objective of this paper is to compare the traffic service proposals in the individual TSPs developed for Line No. 188 based on a comparison with the status quo and a comparison of selected operational indicators, as well as to determine the basic advantages and disadvantages.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ttt-2022-00102023-01-19T00:00:00.000+00:00https://sciendo.com/article/10.2478/ttt-2022-0005<abstract> <title style='display:none'>Abstract</title> <p>Accommodation wagons and night trains have a relatively long tradition in Europe and have been a popular and developed segment of transport for decades. However, at the end of the last century, the trend began to change, and long-distance night traffic began to stagnate. The consequence was the significant restriction and cancellation of several direct international night train connections or direct accommodation wagons in several European countries, including Slovakia, also due to the fast and affordable air transport. In addition, the period of the corona crisis limited long-distance night transport even more significantly. However, bold plans are now emerging in certain countries to reintroduce more night train services. The article deals with a brief analysis of the development of night train connections in Europe, including the current state and vision for the future, while providing systematic conceptual proposals for the development of the mentioned transport segment in the future.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ttt-2022-00052023-01-19T00:00:00.000+00:00https://sciendo.com/article/10.2478/ttt-2022-0008<abstract> <title style='display:none'>Abstract</title> <p>This article is aimed at introducing the issue of simulating traffic processes and the possibility of creating traffic models using software solutions. The introduction describes the basic problems that are present for the responsible authority in the decision-making process on the implementation of transport infrastructure projects and the verification of the validity of their implementation. The importance of computer technology in the process of evaluating projects and the socioeconomic effects they bring is also mentioned. The benefits of retrospective evaluation of already implemented projects and comparison with predictions made in the preparation process in relation to the verification of forecasts and the structure and scope of input data are also indicated. In the next part, the starting points for the creation of traffic models, input data and expected outputs are summarized due to the nature of the performed simulation.

The largest impact was recorded in the second quarter of 2020, from April to June. Passenger transport was more affected than freight transport, with international transport falling by an average of 85% in the second quarter of 2020. The reduction in rail transport in the first months of the crisis was a direct consequence of the public authorities’ response to the COVID-19 crisis (restrictions on passenger mobility) as well as the impact of the global economic slowdown, which generally led to a reduction in transport demand. The paper is focused on the impact of measures in railway passenger transport and subsequently on the implementation of new anti-pandemic measures in the next period. The paper describes the method of the Covid machine, which was introduced for a simple, concise, and comprehensible setting of the system of measures. The system for evaluating anti-pandemic measures is designed to inform about the current level of risk in relation to the measure in place.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ttt-2022-00042023-01-19T00:00:00.000+00:00https://sciendo.com/article/10.2478/ttt-2022-0002<abstract> <title style='display:none'>Abstract</title> <p>At present, new knowledge about the physical nature and empirical phenomena in the field of distribution, losses, recuperation and consumption of electricity in railway transport is undergoing revolutionary changes.

The slowdown in the spread of the COVID-19 pandemic has been achieved by reducing the mobility of the population. The reduction in mobility has had an impact on passenger transport performance. The number of national rail passengers fell by as much as 90% during the first wave of the pandemic compared to the previous year. Several operators, especially new carriers, had to close down, while rail freight operators reported a dramatic drop in volumes as many sectors slowed or even stopped production as a result of the pandemic. The second wave of the autumn 2020 pandemic has forced many countries to take further restrictive measures regarding population mobility. The outbreak of the third wave of the pandemic has prevented a rapid recovery in rail transport, especially for passenger rail services. The paper focuses on the analysis of the impact of the pandemic and the measures put in place on the development of transport performance in rail transport in the Slovak Republic during the COVID-19 pandemic. The paper proposes operational and organizational measures against the spread of the COVID-19 pandemic in railway transport in the Slovak Republic.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ttt-2022-00012022-08-17T00:00:00.000+00:00https://sciendo.com/article/10.2478/ttt-2022-0003<abstract> <title style='display:none'>Abstract</title> <p>The level of development of railway transport is one of the indicators of the economic development of the state.

In the long run, due to the increasingly available taxi services and the lack of connection between rail transport and night public transport, it has a declining share in passenger transport. A new operation proposal is necessary for the regional city of Žilina, which considers not only the factor of continuity, but also other factors, such as economical operation and travel expenses. The main task of the article is therefore to propose a more usable concept that will attract as many satisfied passengers as possible to this segment of public transport.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/ttt-2021-00082021-12-27T00:00:00.000+00:00https://sciendo.com/article/10.2478/ttt-2021-0012<abstract> <title style='display:none'>Abstract</title> <p>Working conditions for drivers in the European Union and Slovakia are governed by European and National regulations.
