The processes of corrosion-fatigue failure of materials in contact with mineral fertilizers are insufficiently studied. As a result of joint influence of atmospheric corrosion and mechanical loads, about 70 to 80 % of machine parts get out of order, 20 to 25 % of which are failures caused by operating overload due to the strength loss because of atmospheric corrosion. A large part of metal structures of agricultural vehicles used to transport mineral fertilizers is under the direct influence of aggressive environments and dynamic loads that occur during the motion by field roads. Saturated solutions of the most aggressive working environments used in agricultural production, in particular ammonium sulphate and nitrophosphate are investigated to reduce fatigue resistance of ordinary steels groups – St3 and St5 and quality steels – 10 Steel, 15 Steel, 20 Steel, 25 Steel when loaded at all levels. The fatigue endurance limit decreases in comparison with air up to 2.02 times in a solution of ammonium sulphate, and to 2.32 times in a solution of nitrophosphate. In organic fertilizer environments, compared to distilled water, the conditional fatigue endurance limit increased to 9 %. The properties of the given materials as an inhibitor of corrosion-fatigue failure were discovered and proved.

“…In previous work, [4] to ensure safe traffic conditions, which are regulated by international and national rules and standards, the dynamic parameters, in particular, stability and handling of the vehicles were studied. Rather sophisticated models for numerical simulation of vehicle dynamics on an uneven road are known [5][6][7][8][9].…”

A free-running model of a truck train, which simulates a truck train consisting of a tow truck MAN TGS 19.360 and a biaxial semitrailer Utility VS2DС with a steerable front axis, has been developed. A semitrailer model is active with the wheel drive enables to control its movement by slow downing one of the wheels. The model was equipped with all necessary control equipment. It proved that driving a semitrailer by slow downing one of its wheels is identical to driving a semitrailer front axis with direct drive and a driver transmission ratio of 0.5. Differences in all cases have not exceeded 12% that is slowingdown one of the wheels of a semitrailer is reasonable for driving a truck train with a long base semitrailer.

“…An adequate level of travel comfort when using public transport in the design of the city's transport network is almost always neglected, especially when transporting the population by public transport in the medium-sized cities, believing that such an indicator as driving time will be the only one that will affect the passengers' choice [18][19].…”

The purpose of the research is formation of passenger transport policy by public transport from the standpoint of determining the level of safety in COVID-19 and passenger comfort with the development of basics for measuring the perception of the most important factors of public transport convenience, minimum discomfort and maximum safety. Methodology. The study was conducted in two stages - inhouse and experimental - the collection and processing of data obtained from the survey of passenger flows. Continuous field research by the tabular method which in comparison with the existing ones is the most time-consuming, but the only one that can provide maximum accuracy of passenger information for further processing of the obtained statistical data of the studied system of public transport. The information obtained by organoleptic means was entered for further processing in the special accounting map, then calculations were performed for traffic areas between the stopping points of each studied route. Findings. The results of field research using the model of discomfort allow us to correctly predict the choice of mode of transport and the behaviour of passengers when using public transport in medium-sized cities. It is proved that the artificial underloading of the vehicle to avoid tight contact of passengers does not affect the level of infection with the virus of COVID-19 and, therefore, this restriction is not appropriate. Conclusions. Formation of the strategy of passengers' transportation in the conditions of COVID-19 is possible only with the use of the characteristic indicators of the transportation of people established by the multi-criteria analysis of a transport network - the level of discomfort, vehicle filling factor, the average time of transportation, the average distance of transportation. It is obligatory to use such means of protection as masks and gloves, provide the enhanced ventilation of the salon, and organize passengers' boarding through the back door with 100 % contactless fare payment.
