The transport market of operator companies of various forms of ownership in Ukraine is constantly evolving, but the tasks associated with the selection and implementation of the priorities of the development of the transport market, the provision of railway services by the carriers - owners of rolling stock, are not fully resolved. There is no regulatory framework that determines the procedure for choosing the priorities of transport market development, their status is not defined, the relation of the selected priorities with the budget of Ukraine is not defined. Therefore, the task of improving the mechanism for selecting scientific and technological priorities for the development of these processes is relevant.

Abstract It is a challenge for the dynamic inspection of railway route for freight car transporting cargo that out-of-gauge. One possible way is using the inspection frame installed in the inspection train to simulate the whole procedure for cargo transportation, which costs a lot of manpower and material resources as well as time. To overcome the above problem, this paper proposes an augmented reality (AR) based dynamic inspection method for visualized railway routing of freight car with out-of-gauge. First, the envelope model of the dynamic moving train with out-of-gauge cargo is generated by using the orbital spectrum of the railway, and the envelope model is matched with a piece of homemade calibration equipment located on the position of the railway that needs to be inspected. Then, the structure from motion (SFM) algorithm is used to reconstruct the environment where the virtual envelope model occludes the buildings or equipment along the railway. Finally, the distance function is adopted to calculate the distance between the obstacle and the envelope of the freight car with out-of-gauge, determining whether the freight car can pass a certain line. The experimental results show that the proposed method performs well for the route selection of out-of-gauge cargo transportation with low cost, high precision, and high efficiency. Moreover, the digital data of the environments along the railway and the envelope of the freight car can be reused, which will increase the digitalization and intelligence for route selection of out-of-gauge cargo transportation.

The article shows the strategic role of cargo air transport in the economies of the world, related to the maintenance of foreign trade, urgent delivery of goods, their transportation over long distances, and so on. The determining factors of the development of cargo air transport in the global economy are systematized: organizational innovations, information technologies, new forms of cooperation of air carriers and logistics solutions. The contribution of air transport to the formation of cargo turnover in Ukraine is determined. The opposite dynamics of volumes of cargo transportation by air and other types of transport is revealed. The contradiction between the low share of air cargo traffic and their strong absolute and structural growth is quantitatively shown. Air freight is defined by a market of oligopolistic competition due to a limited number of economic entities, the dominance of one large and several medium-sized players, the presence of barriers to entry, which are financial-investment and technical-technological nature. The attractiveness of the air freight market for investments is shown given the predominant positivity of financial results and the growing share of profitable enterprises. The institutional forms of organization of cargo air carriers (classic, combined, hybrid) are generalized, their advantages and disadvantages are defined. The principles of functioning of transport chains and realization of multimodal transportations on the basis of cargo air transport are substantiated. The main information systems of booking and management of air cargo transportation, distribution, pricing, calculations, tracking of luggage by buyers and sellers are characterized. The requirements of the International Air Transport Association for the use of innovative e-freight technologies in aviation are summarized, recommendations for joining the subjects of the domestic air cargo market in terms of electronic document management and simplification of customs procedures are developed. The improvement of economic mechanisms of development of cargo air transport in Ukraine on the basis of special economic zones of port type is offered.

Purpose. In modern conditions of the transport services market functioning, the main task of a customer-oriented carrier is to provide high-quality services for the needs of the clientele in cargo transportation, taking into account modern technologies and world experience. The aim of the work is to analyze the existing problems and prospects for organizing piggyback transportation and the effectiveness assessment of this technology application on the example of one of the most potential routes. Methodology. During the research, methods of analysis and synthesis were used to study the main provisions of scientific publications about world experience of organizing piggyback transportation, methods for determining tariffs for cargo transportation and technical - economic calculations for the selected variants. Findings. Ukraine has significant potential for the development of combined transportation, in particular, in international traffic. One of the most efficient and perspective combined transport technologies in the world is a piggyback transportation. A comparative assessment of the shippers’ costs for cargo transportation using different technologies between the terminals Dnepr-Liski and Chop has been carried out. Scientific novelty. The obtained results make it possible to provide a scientific and economic basis for the selection of expedient variants for combined cargo transportation. Practical value. The obtained results of the analysis of the use effectiveness of piggyback technology, taking into account the existing tariffs and competition with road transport on the specific logistics route, can be used for a preliminary assessment and decision-making about the use of different types of combined transport as an alternative to direct road or rail cargo transportation.

In view of the modal parameter identification when only has the output signals of the system under ambient excitations has difficulty, a new method which can identify the structural modal parameters exactly based on singular value decomposition of the power spectrum is put forward. This method is used in the modal parameter identification of a cable stayed bridge under ambient excitations, and the identification frequency is compared with the finite element computation frequency. The results indicated that this method has overcome the subjectivity in modal selection of frequency domain pick-peaking method, choose eigenfrequency and identify close modal accurately and objectively. With the advantages of practical, processing simply and fast.
