The study of the human factor in transport systems is increasingly important, given the rapid level of motorization and the development of the transport industry in general. Accordingly, there is a task of ensuring the appropriate traffic safety level. Today, in this area, are usually taken into account the road conditions and the road`s design parameters, but often miss the role of the \"human factor\". At the same time, with the development of methodologies and technical items, these issues are partly researched and solved. Thus, during considering issues related to traffic safety, it is necessary to pay attention to the drivers` functional state (FS) and psychophysiological qualities, their reliability, factors of negative impact on their body, etc. Goal. The research aims to establish how the bus driver`s FS changes under the influence of various traffic conditions` factors. Methodology. The approaches adopted in the paper, which are necessary to solve the goal, are based on theoretical and practical principles for determining the indicators of a human`s FS during professional activity, their regulatory values, allowable ranges of change, etc. Results. The obtained mathematical and graphical dependences take into account the change of transport process operator`s FS under the influence of such factors as the bus`s speed, the altitude of the highway and the duration of the driver work. The stress index (SI) is selected as the driver`s status indicator. It is established that its values range from 87 to 342 c.u. It was studied that the increase in speed leads to an increase in the driver's SI by about 35%. During the statistical data analysis, it was also found that the highest values of SI were observed on sections of roads at an altitude of 250 - 320 m and 420 - 500 m. At the same time, during the increase of the driver's work duration, the value of the SI increased by about 25% and could approach the value of 250 c.u. In accordance with the above, it can be argued that there is an influence of the driver`s driving conditions and work on his FS. Originality. The obtained regularities reflect the impact of drivers' working conditions on the value of their FS, which affects the probability of their accident-free operation and, as a result, traffic safety. Practical value. The obtained results allow the creation of recommendations for developing schedules of drivers` work and rest taking into account the traffic conditions on the route and the conditions of driver's work.","PeriodicalId":121866,"journal":{"name":"Automobile transport","volume":"361 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115920068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mergers and acquisitions are traditional processes of redistribution of property rights in a market economy. Mergers are often used by companies to gain control over larger market segments and increase performance efficiency. The acquisition process is not always desirable for the target company and is often used to establish control over its assets. Thus, the problems of assessing the risk of hostile takeover of the enterprise and its prevention are extremely relevant at the current stage, especially in the transport sector of Ukraine. Goal. The goal of the work is to develop the methodology for assessing the risk of hostile takeover of a motor transport enterprise and suggest methods for preventing its occurrence. Methodology. During the study, the following research methods have been used: analysis and synthesis, logical analysis. Information resources of the study are electronic information resources and periodic publications. Results. The risk of hostile takeover of an enterprise is the probability that the enterprise will become the takeover target through the legal actions and methods taken by the acquirer, but the acquisition procedure itself is against the wishes of the target’s board. The list of factors that determine the attractiveness of the potential acquisition target includes: the attractiveness of the enterprise in terms of its financial results and performance, the enterprise is not public, it occupies a considerable market segment, the enterprise operates as a joint-stock company, it is attractive in terms of further resale of its assets, the prospects of the industry in which the enterprise operates. According to the results of the studies assessing the risk level of hostile takeover of the group of motor transport enterprises, it has been revealed that 45% of enterprises are in the medium risk group. The following list of measures aimed at defending motor transport enterprises against hostile takeovers has been developed: the formation of optimal share capital structure; share consolidation when the majority shareholder holds the controlling interest; carrying out a sound dividend policy, the continuous monitoring of amounts and maturity dates of accounts payable, preventing the risk of arousing the counterparties’ interest in the resale of debt obligations of the enterprise to others.

The disadvantage of current dependences for determining the acceleration indicators at engine maximum brake power and driving tire-to-surface friction coefficients is that they are adequate only if the engine and transmission parameters provide power input to the drive wheels rolling without slipping regardless to speed. To eliminate this drawback, it is necessary to take into account that the power input to the drive wheels depends on the engine shaft speed, and therefore on the speed of the vehicle when accelerating.

The purpose of the work is to further develop the theory of the automobile by improving the dependencies that allow determining the automobile acceleration rates and assessing the nature of its acceleration process from the design factors.

In recent years, Ukraine has seen a sharp decline in ambient temperature, especially in the winter. Accordingly, this has a negative impact on the performance of car engines (difficult to start and prolonged warm-up), as the lion's share of private sector cars are parked in open areas and are subject to sudden temperature and humidity changes. Therefore, to partially solve this problem, our attention was focused on the air lines of the intake system of the gasoline engine, as this system is easily accessible and does not require significant design changes for its modernization. Goal. The purpose of the work is to ensure the ease of starting the gasoline engine and reduce the time to warm up. Methodology. Operation of the car in the conditions of the lowered temperatures, essentially promotes deterioration of its fuel economy. The basis of such a negative process of fuel consumption is incomplete combustion of the working mixture. And this is the deterioration of spraying and evaporation of fuel and increasing the duration of engine warm-up. At such low ambient temperatures, the effective operation of the car in a garage depends significantly on the method of its preparation (which should at a minimum cost of fuel and energy resources to ensure rapid and reliable engine start and accelerated warm-up). We decided to obtain thermal energy to heat the inlet air at no additional cost. This is the installation of a gasoline engine with a spark ignition of the incandescent coil in the intake air line, which will receive power from the battery. Such modernization of the system does not require major design changes and significant financial investments Unresolved issues remain to assess the effectiveness of the process of heating the air entering the combustion chamber of the engine to create a working mixture. It should be noted that the optimal heating of the engines is most appropriate to carry out (ie heating the coolant and oil in the engine lubrication system) not to the temperature of the operating thermal mode, but to the temperature that ensures its reliable start. Results. The scheme of connection of a heater of intake air in an onboard electric network of the car is presented. The results of the heat balance of the studied gasoline engine (using cold and heated air flow) during its heating are obtained. The optimum temperature of the warmed-up engine at which further economical operation of the car is possible is established. Originality. This spiral heater was first used to heat the intake air charge during the start-up and warm-up of a gasoline engine. Practical value.
