Research of Changing the Driver's Reaction Time in the Traffic Jam

Abstract

In this research the main attention is paid to establishing dynamics of changes in the driver’s reaction time in a traffic jam that affects traffic safety.With the help of the regression model, graphs of driver’s reaction time are constructed taking into account different age groups and types of the nervous system depending on the initial level of fatigue at the entrance to traffic jam and duration of traffic jam.Analysis of these graphs allowed us to establish trends in the driver’s reaction time in traffic jams, which indicate an increase in the driver’s reaction time with an increase in the time spent in the traffic jam. However, at the beginning of the traffic jam, depending on the initial fatigue level, different combinations of the reaction time change occur at the entrance to the traffic jam: at low values, the reaction time increases, and at high values it decreases. It was also found that the traffic jam has a different effect on the reaction time of drivers depending on their temperament. For the reaction time of the driver-phlegmatic traffic jam does not have a significant impact.

Development of models for assessing a driver's failure­free operation in a transportation system under conditions of traffic congestion

“…Authors of paper [14] considered such qualities of a driver as a response time of a driver, work experience, and temperament in their studies. They noted that being in a traffic jam had a negative effect on the psychophysiological qualities of a driver increasing the response time.…”

“…The model of changes in (ΔT r ) response time of a driver developed in [14,27] takes the following form:…”

“…There were corresponding studies presented in [14] to construct a mathematical model (7) of an impact of traffic jams on the functional state of a driver and his response time. We measured the functional state and the response time of drivers before a traffic jam, during their stay in a traffic jam and after it [27].…”

Modeling the effect of traffic jam on driver’s level of fatigue

“…The traffic flow may be also considered as a complex system that needs to be constantly managed. The driver is the active element of this system, and his state determines the efficiency of the entire transport system of the city to a large extent [1][2][3].…”
