Abstract: Nowadays, road safety depends on the driver of the vehicle, who is the part of the system "driver - car - road - environment". It should be noted that he is the main part of this system. The functional state of his body influences his behavior and reliability. The functional state of a person, in particular the driver, is often the indicator that carries information about the body’s energy reserves. Accordingly, this indicator can be used as data about the readiness of the operator to perform his professional tasks. The concept of functional state and its research are often used in sport`s medicine to identify the early stages of fatigue in athletes and their functionality [1]. However, scientists consider the concept of a functional state as an indicator of a person’s mental state. This is due to the fact that different mental states of the human body are a phenomenon that reflects its interaction with the environment, which is represented at some point in a particular situation. The analysis of existing scientific works on the influence of traffic conditions on the functional state of vehicle drivers is carried out in this work [2 - 4]. Accordingly, it was concluded that the conditions in which the driver works significantly impact his body. In particular, such factors must primarily include the area in which the bus is moving. According to the results of the analysis of existing research, it is established that the greatest influence on the body of the driver during his work is carried out by the conditions of movement in the mountains. That’s way, the research of the driver`s functional state changes and its dynamics in such traffic conditions is relevant and requires detailed study. Study object – the process of the bus driving by a driver in mountainous traffic conditions. Scope of research – reliability of the driver’s work under the influence of mountain traffic conditions’ external factors. Goal of research – patterns’ identification of changes in the bus driver`s functional state while driving in mountainous traffic conditions. To achieve this goal, it is necessary to solve the following tasks: - to analyze scientific publications on the topic of the research; - identify the main methods of the research and justify those that will be used to analyze driving conditions and drivers` functional state; - research the main indicators of the drivers` functional state while driving buses in mountain traffic conditions; - to process the obtained research results and establish the appropriate mathematical and graphical dependencies; - based on the established dependencies to develop recommendations on duration of work and rest of buses` drivers taking into account their functional state and mountain traffic conditions. The analysis of the bus route on which drivers` functional state was researched is carried out in work. This takes into account the parameters of the highway, its height position. There is a clear gradation of plain and mountain traffic conditions. The parameters of buses moving along the specified route are analyzed. By conducting research, the dynamics of change in the activity of drivers` regulatory systems while driving on the route in the forward and reverse directions, which runs in the plains and mountains. Based on these data, the mathematical and graphical dependences of changes in the functional state of bus drivers in mountain traffic conditions were determined. Key words – functional state of the driver, mountain traffic conditions, traffic safety, reliability of the driver, stress index, activity index of regulatory systems References 1.
