Definition of the driver reaction time

abstract

English

Nowadays, driver reaction time is a main characteristic describing a driver behavior, therefore driver reaction time is the most important driver characteristic in the field of the traffic accident. Driver reaction time is divided into three main parts(visual, psychical and physical reaction time) and their duration is adiscussed topic among experts of the traffic accident field. Mostly,the duration of the driver reaction time(or its visual part) was in vestigated and evaluated from eyetracking measurement swhich can define the visual part of the reaction time accurately. But not all parts of the driver reaction time can be defined via eyetracking method. The aim of this article is to introduce the new approach to defining the physical part of the driver reaction time by combination of eyetracking and electromyography methods. Drivers are monitored during their driving in the real traffic. The eyetracker was mounted on the driver head and signals of seven muscles of the right lower limb involved in the movement of braking were acquired to determine the physical part of the driver reaction time. The results should offer a more accurate definition of the physical part of driver reaction time and its dependence on the type of stimuli dealt with by driver while driving.
