The modern approach to the design of road culverts involves the use of computeraided design (CAD). In design organizations of Ukraine software products of the Minsk company CREDO are being used for calculations of capacity of culverts by GRIS_T. Since 2019, the UKRRVS program is being developed to calculate culverts of road structures according to Ukrainian standards. At the moment, the program has the calculation of stormwater runoff according to MADI/SoyuzDorProekt formula and meltwater runoff (according the Road Handbook). In 2020, a new stage of automated calculation of road culverts started - calculations of capacity. The article presents the automated calculation of road reinforced concrete round culverts for pressureless operation. Goal. It is proposed to automate the calculation of road reinforced concrete round culverts for pressureless oper-ation. Methodology. The current methods for calculating the throughput of reinforced concrete road culverts have been used. Programming was carried out in the C# language using object-oriented programming. Results. The state of affairs in the auto-mation of hydraulic calculations in the road industry in accordance with Ukrainian standards was analyzed. It was concluded that at the moment the production uses the GRIS program of the CREDO company. The UKRRVS program is being developed. In this program, the issue of automating the calculation of the throughput of round culverts for operation in freeflow mode is relevant. The question of the methodology and algorithmization of this calculation, coding and interface support has been resolved. Practical value. The algorithm for calculating road culverts has been developed. A part of calculating the throughput of road culverts has been created in the UKRRVS program. This part covers the most com-mon group - round reinforced concrete culverts for freeflow operation. Originality. The interface has been created for the automation program for calculating road culverts. When you click the button “Round reinforced concrete pipes” in the main menu of the program UKRVS 21, the window “Calculation of a round reinforced concrete pipe operating in pressureless mode” opens. The calculation consists of three parts: the area of formation of initial data, the button “Calculate”, and the area of output of results of calculations. The area of formation of ini-tial data consists of 7 points. The area of the results of calculation of round reinforced concrete road cul-verts working in a pressureless mode consists of 14 points.

Gelendzhik is the resort town, there aren't a lot of industrial enterprises here. The main pollutant is transport. The work purpose is the assessment of a condition of the artificial landings of a pine located along the Federal highway "Don" and landings, which is nearly the sea coast. Researches were conducted to a standard technique of the General vital state (A. S. Bogolyubov). The assessment of a condition of pines was carried out during 6 years: from 2010 to 2015. For carrying out research we used 6 experimental grounds on the Markotkhsky spine and 2 control grounds within the town. We investigated 24 trees on each platform, middle age of the trees were 30 - 40 years. Results. 1. The condition of trees in the pine forests located in immediate proximity with the Federal highway "Don" (No. 1, 2, 3) is unsatisfactory. As even weak influences of the majority of atmospheric gaseous pollutants (sulphurous gas, nitrogen oxides, etc.) give effect of a necrosis and hloroz of pine needles, the condition of pines is connected with technogenic pollution. So near the Federal highway "Don" the air environment is strongly polluted by exhaust gases. Information of 2012 confirm that negative influence of the route on Markotkh's vegetation decreases at reduction of load of the route. 2. On the sites located above on a slope (No. 4,5,6) thanks to remoteness and the wind mode intensity of influence of pollutants is lower and a condition of pines the quite satisfactory. 3. Trees on the sites located near the sea (No. 7,8) are in a good shape. Small deterioration of a state is noted in very droughty years. Conclusion. Results of six years' research show that the condition of the plantings which are in close proximity with the road worsens. It is explained by increase in intensity of the movement on the road, especially during a resort season. Gelendzhik is the city with a good ecological shape, but the damage to environment is already caused. If not to take measures, we can lose a unique part of the nature in the future, recreate it will be impossible. Measures of reduction of negative impact of exhaust gases were offered. Results of researches are transferred to ecological department of the City administration of Gelendzhik.

В статье проанализированы трудности в процессе строительства автомобильной дороги от Братского моста через Енисей в сторону Абакана, связанные с отсутствием учета на стадии проектирования осложнившихся гидрогеологических условий, влияющих на опускание моста и дороги. Оползневые процессы, созданные искусственно при сооружении выемки дна автомобильной дороги от Братского моста более 40 лет развиваются на участке дороги Абакан-Подсинее перед железным и автодорожным мостом через Енисей. Как и в первом случае на стадии проектирования не выполнены гидро-геологические исследования. The article analyzes the difficulties in the process of construction of the highway from the Bratsk bridge over the Yenisei river to Abakan, associated with not taking into account the complicated hydrogeological conditions at the design stage, associated with the lowering of the bridge and road. Landslide processes created artificially during the construction of the dredging of the road bottom from the Bratsk bridge have been developing for more than 40 years on the Abakan-Podsinee road section in front of the railway and road bridge over the Yenisei. As in the first case, hydrogeological studies were not performed at the design stage.

The UAV technology seems to be highly future-oriented due to its low costs as compared to traditional aerial images taken from classical photogrammetry aircrafts. The AGH University of Science and Technology in Cracow - Department of Geoinformation, Photogrammetry and Environmental Remote Sensing focuses mainly on geometry and radiometry of recorded images. Various scientific research centres all over the world have been conducting the relevant research for years. The paper presents selected aspects of processing digital images made with the UAV technology. It provides on a practical example a comparison between a digital image taken from an airborne (classical) height, and the one made from an UAV level. In his research the author of the paper is trying to find an answer to the question: to what extent does the UAV technology diverge today from classical photogrammetry, and what are the advantages and disadvantages of both methods? The flight plan was made over the Tokarnia Village Museum (more than 0.5 km<sup>2</sup>) for two separate flights: the first was made by an UAV - System FT-03A built by FlyTech Solution Ltd. The second was made with the use of a classical photogrammetric Cesna aircraft furnished with an airborne photogrammetric camera (Ultra Cam Eagle). Both sets of photographs were taken with pixel size of about 3 cm, in order to have reliable data allowing for both systems to be compared. The project has made aerotriangulation independently for the two flights. The DTM was generated automatically, and the last step was the generation of an orthophoto. The geometry of images was checked under the process of aerotriangulation. To compare the accuracy of these two flights, control and check points were used. RMSE were calculated. The radiometry was checked by a visual method and using the author's own algorithm for feature extraction (to define edges with subpixel accuracy). After initial pre-processing of data, the images were put together, and shown side by side. Buildings and strips on the road were selected from whole data for the comparison of edges and details. The details on UAV images were not worse than those on classical photogrammetric ones. One might suppose that geometrically they also were correct. The results of aerotriangulation prove these facts, too. Final results from aerotriangulation were on the level of RMS = 1 pixel (about 3 cm). In general it can be said that photographs from UAVs are not worse than classic ones. In the author's opinion, geometric and radiometric qualities are at a similar level for this kind of area (a small village). This is a very significant result as regards mapping. It means that UAV data can be used in mapping production.

Research Findings

This study focuses on a wide range of issues related to the effects of integration process on the development of economic relations, in particular, in the road transport services market. Special emphasis is put on the critical role of integration in contributing to building circular technological supply chains, ensuring sales coordination and management, reducing unit costs and increasing labor productivity. It is argued that the outcome of integration translates into a cohesive economic mechanism which in addition to its integrated elements is characterized by the presence of a core coordination element. The article offers a definition to a public-private partnership phenomenon, identifies its advantages and disadvantages, explores the mechanisms of public-private partnership implementation as well as suggests a toolkit to optimize the partnership functioning for integrated structures. This is a pioneering study that provides a rationale for the need to use several public-private partnership patterns simultaneously together with developing a mechanism for carrying out public-private partnership which is proposed to be consolidated into the mechanism of integrated partnership viewed as the most preferable one to be implemented in the market of road transport services. It has been verified that the integrated partnership pattern provides an opportunity to develop competitive advantages of all its participants. The research findings have enabled to make the following generalizations: the existing partnerships differ in types of arrangements and institutional support; prior to making a decision to launch a specific integrated partnership project, the mechanism of its implementation should be envisaged; to enhance the efficiency of the integrated partnership project implementation, building relevant infrastructure facilities is paramount; the prospects for further integrated partnership project operation assume the utilization of a network mechanism of public-private partnership which best meets the needs and the specifics of the road transport services market.
