Evaluation of skid resistance of the road surface is a very important issue of roads maintenance because this indicator is one of the main transports and operational indicators of the road surface, on which road safety depends. It is known from many sources that one of the causes of road accidents (accidents) is the low value of the skid resistance of the road surface.After analyzing the existing methods and tools for evaluating the skid resistance and the lack of those that could correspond to the accuracy of the results of current regulations, the National Transport University decided to improve the methods and tools for evaluating the skid resistance road surface in Ukraine.The purpose of the development was to improve the methodology for evaluating the properties skid resistance of road surfaces by increasing the requirements for testing, improving the accuracy of instruments, informativeness and productivity of measuring the parameters of skid resistance qualities of road surfaces. The result of many years of work was an improved methodology, on the basis of which the regulatory documents of Ukraine were approved and the equipment was created, which allows to obtain the relevant value of the coupling qualities of road surfaces with confidence.According to the results of experimental studies, the correlation coefficient between the readings of various modifications of the developed Universal road measuring equipment "UDVO" is from 0.955 to 0.981, and the deviation of the equipment readings from the values of skid resistance qualities determined by standard methods do not exceed 5%.

One of the most promising directions of solving the satisfying constantly growing problem of Ukrainians residents tourist, business and migration activity is the diversification of the rail transport activity in the International passenger transportation market. In the conducted studies, the analysis of possible variants of passenger transportation logistics from Eastern Ukraine (in particular from Kharkiv) to Krakow was made. For comparison, seven possible variants of transportation and a new project solution (direct passenger train Kharkiv - Kiev - Lviv - Mostiska II - Krakow with the perspective of continuation of the route to Prague or Vienna) is selected. Based on the SWOT analysis, as well as marketing and logistics research on project variants, it has been proved that the proposed direct rail rout between Kharkiv and Krakow can compete on an equal footing with existing variants of transport.

The model of complex transportations in the transport system is developed, which makes it possible to systematically approach the problem of optimization of International transport of non-homogeneous cargoes under the combined scheme of the use of various types of transport (automobile, water and railway) taking into account the whole spectrum of restrictions that exist in systems of this kind. The program complex for the optimization of International freight transport on the transport system of Ukraine and Western Europe, which is based on the model of management of multimodal freight traffic in International traffic, takes into account the throughput of transport nodes and communications of transport systems, and also can solve transport problems in the event of imbalance of volumes of transportation of heterogeneous cargoes.
