Abstract: Road traffic safety largely depends on the reliability of the functioning of the “driver-car-road-environment” system. It is a complex system, the work of which is influenced by a significant number of both internal and external factors. At the same time, one of the key links on which its reliability depends is the “human factor”. In particular, as statistics show, it is precisely because of her fault that the majority of traffic accidents occur. At the same time, the reliability of a person’s work and behavior is rather difficult to predict and forecast [1]. One of the indicators that are often used to reflect the readiness of the human body to cope with labor duties is its functional state. In transport studies of the driver, approaches based on recordings of electrocardiogram, electroencephalogram, oculogram, etc. are often used as such an indicator. However, the most widely used are methods and techniques that allow determining the functional state of the driver based on the work of his cardiovascular system. In this case, the values of the stress index and the activity indicator of regulatory systems can be used as indicators [2-4]. In this master’s thesis, the dependence on changes in the functional state of bus drivers during their work and under the influence of passenger traffic indicators is established. On-site studies of passenger flow values were carried out using blank methods on public transport routes in Lviv, in particular on bus routes #3A and #21. Based on this, a graphic representation of the dynamics of changes in the capacity of passenger flows was created and the value of the filling coefficients of the interior of the rolling stock was calculated. At the same time, the drivers’ functional state indicators were recorded based on recording data on the work of their cardiovascular system. Based on the above-mentioned data and their analysis, mathematical and graphical dependencies were created that reflect the influence of the bus interior filling factor on the driver’s stress index. The object of research is the functioning of public transport routes. The subject of research is the change of the driver`s stress index during his work. The purpose of the research is to identify the influence of passenger flow indicators on the functional state of the bus driver. The dependencies between the bus filling and the functional state of the driver were established. However, as its value increases, the driver’s stress index does not change uniformly. This indicates that after the value of the filling factor is greater than approximately 0.8 - 0.9, the driver’s functional state is already influenced to a greater extent by external factors of traffic conditions, and not by the passenger flow and its indicators. Key words – vehicle, driver, bus, passenger flow, functional state, stress index. References 1. Postranskyy, T., & Vovk, Y. (2020). Changing of the bus drivers functional state in city conditions.
