We present a comprehensive methodology for a two-step approach to address the task at hand. The first step involves the optimal placement of charging stations, while the second step focuses on determining the necessary capacity of the charging stations based on traffic factors. This methodology is applicable to countries, states, or specific areas where the placement and optimization of charging stations for truck road transport are being considered. We identify the key inputs required for solving such a task. In the results section, we demonstrate the outcomes using a model example for the Czech Republic.

The air transport network is one of the most important and critical infrastructures in today's global economy. Air transport would not be able to operate without the air network. This fact significantly contributed to interest in a closer study of the issue of air network status assessment. The aim of this article is to evaluate the European air network by identifying and evaluating major European airports based on scheduled flights. Robustness of this air network was determined with regard to its evaluation. According to research, a suitable methodology was chosen which is describing the organization of data, specification of the research area and selection of method. Civil international airports which are located in European countries recognized by their entire size and handled at least 1 million passengers in 2018, were chosen as the basis for the creation of the European air network model and following evaluation. For these airports, individual scheduled flights were searching including their frequency during the selected period on 11-17 November 2019. The method of centrality used in the field of graph theory was chosen to evaluate the air network of these selected airports with regard to their connectivity. The obtained results identified the most important airports of the European air network and thus represent status assessment of air network during the winter flight schedule 2019/2020. These results were used to monitor the robustness of the European air network as a whole. The robustness of the air network was monitored based on a simulation of the sequent closure of the most important airports in the network with regard to the change of average path length and the size of the giant component. The European air network becomes inoperable when 19-20% of the best evaluated airports in the network are closed.

The subject of the study “Research of the Employment in Air transport in the Czech Republic” is to analyze employment in the aviation with an emphasis on its contribution to the Czech Republic. In the context of employment, this study deals with the position of air transport in relation to the transport industry and the whole market in the Czech Republic. The main aim of this study was to find out how many people work in the aviation, what is the development of employment in aviation over time, but also to compare employment in the aviation versus the transport industry and the whole market in the Czech Republic. This study used quantitative analysis, which helped to fulfill another goal of this study, namely, to analyze the efficiency of employment in aviation. In air transport, the following quantities were found: the number of employees, average monthly gross salary, total turnover and its effect on gross domestic product, turnover per employee, total profit and profit per employee, the ratio of labor costs to turnover, profitability, and efficiency of employees. The source of data on the transport sector or the market in the Czech Republic was mainly the database of the Czech Statistical Office. In general, it can be said that air transport follows the development trend of the entire market. During the research period (2014–2018), growth in the number of employees, average gross monthly wages, total profit, and thus profitability in the aviation industry was recorded. Still, the share of air transport in the gross domestic product also grew. Air transport thus contributes not only to the level of employment and thus also to the general well-being of people but also contributes to the creation of GDP, which indicates the performance of the economy of the entire Czech Republic.

The initial motivation for studying and researching air transport socio-economic impacts is quantifying the value that air transport brings to the Czech Republic. The main challenge is to explore a methodology that would describe the macroeconomic and microeconomic relations within the Air transport industry. These relations will define the directions of the market forces flow and thus the Czech Republic’s value. The authors of the paper use an approach that follows methods and standards for collecting and processing economic and statistical data introduced by the International Civil Aviation Organization (ICAO), Eurostat, and the Czech Statistical Office (CZSO). The authors incorporate economic definitions and standards published by the United Nations under the World Trade Organization (UNWTO) and other accounting and statistical entities, which results in creating a methodical description of chosen relations. The methodical description leads to the quantification of the value. In a practical sense, it is a matter of determining the origin of the data sets according to which the selected relations will be defined. The paper focuses on the expression of Air transport’s primary and secondary effects and the description of the proposals, which will be part of the methodology.

The purpose of this paper is to describe the upcoming changes that will bring the transition from piston engines to all-electric aircrafts. The article focuses on the differences in operation of small general aviation aircrafts. This topic is timely, as the first all-electric aircraft was certified by the European Union Aviation Safety Agency (EASA) in 2019. As there are no data concerning this new type of operation available, the data have been derived from other applicable sources. At first, we compared the energy consumption of the same aircraft with the piston engine, and then afterwards with the retrofitted all-electric variant. Our results focus on the difference in fuel price, which is discussed in the context of electricity price comparison with AVGAS prices. Moreover, we discuss the environmental impacts, especially concerning electricity source mix and emissions produced (we estimate both with and without life-cycle assessment). In the discussion, we compare the results and identify the benefits of an all-electric solution. Furthermore, several operational restrictions of all-electric aircrafts are discussed.

Containerisation of goods is a trend, which is constantly increasing in a meaning of volume of transported goods. The most of bulk goods are transhipped through container terminals in seaports. Concerning this fact, it is necessary to define logistics operations for loading, transhipping and unloading in every port. A base is an analysis of a current state of a container transhipment in seaports and a definition of bottlenecks in logistics chains. Thanks to this a functional logistic terminal model can be established.

The aim is to determine a forecast of a future development of air freight transport using selected prognostic methods. Development of air transport is an interesting and important topic nowadays. Its intensity is growing especially between Asia and Europe. Asia, more precisely The People's Republic of China, exports products to the entire world as a dominant major trading partner. It is important to identify all effecting factors for development of any mode of transport, including air transport, that may cause growth or decline of transport such as global financial crisis, social impacts, GDP development and geographical conditions. Possibility of using different prognostic methods for Asia-Europe route is discussed in this contribution. Results of relevant prognosis are presented in this contribution for comparison.

Container transport of goods between China and Europe, respectively between China and Czech Republic, is an important part of trade betweent these countries and its volumeis still increasing. This contribution contains analysis of the current state of two modes of transport, namely maritime and rail transport between Far East and Europe, respectively between Far East and Czech Republicv. Both of these modes of transport are environmentally friendly and should be used for transport of goods in the future. One part of this contrubution contains comparison of selected aspects. Selected aspects are prices, time of transport and safety. Comparison of the two modes, maritime and rail transport is reasonable, because prices, time of transport and safety are important for a decision, which mode of transport to use.

Transportation indicates the state of society in the areas of consumption of raw materials, resources or finished products or their parts. The existing imbalance of incomes of the population on a global scale leads to the transportation of products with low production value, and if travel costs are included, these products are cheaper than the products in the country of consumption. The result is a growing volume of freight transport, increasing environmental pollution and social and economic impacts. The level of con-gestion and how the transport system works thereby impacts the social and economic climate. Given that freight transport is operated on a scale that transcends the borders of individual countries, the specified im-pacts and effects have an international importance. In light of these facts, it is very important to choose means of transport which must meet the required criteria. Requirements for changes in trans-portation and logistics systems and the use of appropriate modes of transport can also develop, which in turn causes economic changes. In the future, it will be necessary to seek out transportation systems that will function optimally, efficiently use possible and acceptable sources, and will be environmentally friend-ly and safe.

Air transport is experiencing a sustained growth in volume—whether this relates to passenger or freight transport. The number of aircraft is increasing, as well as the number of operated routes, and target destinations are changing. As a result, in some cases a heavy burden may be placed, or is already being placed on the air space and the airports concerned. In addition to other demands put on this type of transport, it is necessary to ensure also a high standard of safety and security, which is becoming an increasingly important factor. This paper emphasizes the importance of airport checks before passengers board or goods are loaded on the plane. The paper identifies risks that might endanger transportation safety and presents proposals for minimisation of these risks. Moreover, the paper presents a diagram of procedure to be taken during an airport check in order to eliminate critical points prone to failure of the human factor or errors occurring where technological elements are used in control processes. It may be stated that if the proposed procedures and measures are followed, any possible risks will be minimized, with the result of an increased safety in air transport.

Problematika návrhu vysokorychlostních tratí je velmi aktuálním tématem, zejména z důvodu napojení ČR na evropský systém VRT. Problematika návrhu se však netýká jenom přípravy technologických částí stavby. Nejdůležitější je příprava území aby navržená stavba mohla být naplánována, tzn. je nutno uvést do souladu navrženou trasu s dotčenými územními plány, posoudit vliv na životní prostředí a další faktory. Součástí článku je uplatnění těchto hledisek při posouzení návrhu modelové trasy VRT v úseku Praha Drážďany, což ve výsledku bude znamenat propojení letiště Václava Havla Praha a letiště v Drážďanech.

It is very important to compare the risks in transportation of goods in multimodal transport. Today, multimodal transport is preferred because by combining a number of separate transportation modes, one can transport goods at great distances, even at a global scale. Multimodal transport is defined as transport using two or more transportation means. This means that trans-loading of goods occurs, and can occur several times. And it is at these times when risk is higher, both of damage and theft. In order to simplify trans-loading, containers are used which can be used on all transportation types. This eliminates the risk of damage to the goods while handling during the trans-loading. At the same time, however, demands on securing the container grow, as this security must meet the conditions of all transportation means which will be used during the course of transportation. Damage to the transported goods can be a highly risky affair, such as when carrying hazardous goods and in this case protection must be secured to prevent any danger to human health or life, damage to the environment, or theft of the goods. It is necessary to mention the importance of the human factor as a risk during the transportation of goods. It is necessary to evaluate it together with the other risk factors that occur during transport. It is essential to compare and assess the system of checks and identify weak points in the safety and security of goods in the multimodal transportation process.

Like every project, a transportation project must be prepared in several variants, which are evaluated in terms of the number of risks and negative impacts thereof. All phases must be addressed during the preparation and execution of a transportation project, i.e. initiation, preparation, execution and commissioning phases. In each of these phases, certain risks may emerge; however, a certain risk may be present during all project phases. Accordingly, a risk analysis must be carried out over the duration of the project period, even repeatedly. Identification, evaluation and comparison of risks in all phases of a transportation project play an important role for decision-making as to whether the given project should be implemented, but also for the subsequent phases until the project is successfully completed. The present paper includes a model example of a risk analysis in the individual project phases.

EU legislation in the field of transport and energy is focused on the safety of transport and storage of LNG, environmental friendliness, but above all to protect the health of the population. LNG is an important alternative to conventional ship fuel. Under current IMO guidelines and ADN, LNG fuel tanks installed in the vessel must meet the criteria of the LNG tank from a group of independent types A, B, or C. Specifically, the fuel tanks of inland waterway vessels are the type C. One method for determining the strength characteristics of the LNG is the tank finite element method (FEM), which is evaluated using the HMH stress hypothesis. The result is a set of the maximum stress characteristics and assessment of the suitability of LNG tanks on inland vessels and floating terminals.

The Czech Republic has been historically a major producer of engineering products that includes unique products, although their size usually exceeds standard dimensions or weight. These types of products have high value added and are important for export. In the heavy machinery it is e.g. mining and metallurgical equipment, and other components for installation of turn-key investment units. So called light engineering also produces machinery and equipment, which can be categorized as oversized items. Locations with manufacturing plants that produce products for the chemical industry. Energy and also the automotive industry are located all over the Czech Republic. Important areas of production are especially the Ostrava region, the Pilsen region, The Central Bohemia region, the Usti region and also the South Moravian region. The transportation of these oversized items is from logistical, transportation and organizational point of view such a complicated process into where not only a manufacturer and a carrier enter. Also relevant government authorities and other organizations are having high influence. Although the transportation of oversized items is only a small part of the total volume of traffic to and from the Czech Republic, it is a very important part, specifically for export. It is necessary to pay a special attention to this type of transportation also in terms of possibility of using different transportation modes.

Transportation of goods in cities in modern times is causing a situation that leads to traffic congestions and a disproportionate burden on the environmental by transport externalities. It is necessary to design transportation of goods in “Smart Cities” in such a way as to ensure that the lives of citizens are affected as little as possible in terms of a friendly and functioning society. It is possible and necessary to utilize all modes of transport for transportation of goods, i.e. rail, road, air and inland waterway transport so that a follow-up and continuous logistic chain can function. Another very important factor is the organization of supplying in cities in a way that burdens the living space of the population as little as possible.
