Abstract

This article considers the problem of determining the reaction time of sanguine drivers of different age categories in the city's transport system in conditions of high-density traffic flow, close to congestion. Prolonged exposure to high-density traffic leads to a deterioration in the functional state of the driver and to an increase in his psycho-emotional tension. A change in the functional state causes fatigue in the driver, which in turn leads to an increase in his reaction time, which affects road safety. The assessment of the driver's fatigue level was carried out by measuring an electrocardiogram and analyzing the unevenness of cardiac intervals, which are a universal response to all types of loads. A model for estimating changes in the reaction time of a sanguine driver based on a regression model of changes in his fatigue level is proposed. The graphs show the changes in the reaction time of drivers of different ages during their stay in traffic congestion. It was revealed that the reaction time of the driver in the first minutes of being in a traffic jam changes slightly, due to the presence of reserve compensatory capabilities of the body, however, after the fifth to sixth minute, an objective process of deterioration of the functional state begins. It was found that the change in the reaction time of a sanguine driver in a traffic jam primarily depends on the initial level of fatigue. When the driver stays in a high-density traffic flow with the initial state of optimal voltage of the regulatory systems, the change in his reaction time by the end of the jam reaches the greatest value. It was also revealed that the greatest changes in the reaction time of a sanguine driver occur in older drivers.
