Abstract. General data on the network of Ukrainian highways are presented. Th e analysis of design methods of highway reconstruction based on the theory of traffi c fl ows and economic calculations of its repay time is made. Th e relationship between traffi c intensity and speed is shown by considering the theory of traffi c fl ows. Th e methods, taking into account the principle of eff ectiveness of highway reconstruction based on its repay time, are discussed.
Purpose. The purpose of the paper is: (1) the definition of perspectives development of Ukrainian railway tourism on the narrow gauge lines of Zakarpattia; 2) technical condition analysis of Borzhava narrow gauge railway for the project to restore the effective functioning of mountain railways track, width 750 mm in the Carpathian region, with the possibility of their accession to the distributed travel network; 3) the study of the modern state and tendencies of development of tourist industry of Ukraine and the passenger economy of national railways; 4) clarification of the role and place of the railway tourism in the transportation system. Methodology. The expert group has carried out field inspections and field investigations of facilities track facilities and passenger infrastructure, rolling stock and ancillary industries involved in the functioning narrow-gauge railway. It was estimated the overall technical condition of the railway track and engineering structures section of narrow-gauge Railways in the Carpathian region. Findings. In the framework of on-site examinations of the expert group found that the objects of tracks, passenger and freight infrastructure, rolling stock and ancillary industries involved in the operation of narrow-gauge Railways are in poor condition and require significant updates and major repairs. But the routes of passenger trains remain fit for participation in the project of development of railway tourism of Ukraine Originality. For the first time the state of the narrow-gauge railway for further implementation of the project on the development of rail tourism in Ukraine was realized. The analysis of foreign experience of organization of railway tourism has been carried out. The modern state and tendencies of development of tourist industry of Ukraine was studied, the factors of competitiveness of rail transport for providing tourist transport in Ukraine were identified and systematized. Practical value. The recovery and effective functioning of mountain railways with a width of 750 mm in the Carpathian region will give an impetus to the tourism development, engineering, construction and energy. At the same time, these actions will allow us to finally implement a scientifically-based effective flood control measures that will protect the population from natural environmental disasters.
The recent problem of estimating the residual life of metal structures for handling equipment is actual, since more than 90% exhausted its regulatory resources. The current paper proposes an approach to solve this problem by using the coercive force. It is shown that in order to determinate damage of dangerous element of crane it is needed to know not only a coercive force but also a stress. Mathematical model is proposed to determine the damage of metal ware.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
