In this article, as an object of research, the process of a driver's work activity is considered when performing his functions in the urban transport system. Studies have been conducted to assess the impact of traffic congestion on the functional state of a choleric driver, which is one of the widespread and well-known types of temperament. The hypothesis of the study is that a change in the functional state of a driver in a traffic jam affects the degree of fatigue and depends on the condition of the driver and the parameters of the congestion. To assess the level of fatigue of the driver, the concept of the cardiovascular system is used as an appropriate mechanism of adaptive activity of the body. At the same time, an electrocardiogram is measured and the irregularities of cardiac intervals are analyzed, which are a universal response to all types of loads. The degree of fatigue level of the driver is measured in conventional units and is determined by a special technique taking into account statistical indicators, histogram indicators and spectral analysis of cardiac intervals. Using a nonlinear regression model of changes in the functional state of a choleric driver, the corresponding patterns of changes in the level of fatigue for traffic jams of different duration have been determined. As a result of the analysis of the constructed graphs of changes in the final level of fatigue of choleric drivers of different age categories in congestion, it was found that the most significant factor is the value of the initial level of fatigue of the driver. The second most important factor influencing the change in the final level of fatigue of a choleric driver is the duration of traffic congestion. It was revealed that this factor affects the degree of fatigue of the driver at the end of the jam only together with the initial level of fatigue. The age of the choleric driver was in third place in terms of the importance of influencing his final level of fatigue in congestion. It was also found that older drivers, compared with younger drivers, experience the negative impact of traffic congestion with an increase in its duration. Studies have shown that traffic jams lasting more than twelve minutes lead to a significant increase in the final level of fatigue of the choleric driver. This may increase the likelihood of a traffic accident. The established trends in the functional state of the choleric driver in traffic congestion allow us to predict his behavior after congestion and evaluate possible patterns of development of the road traffic situation.
