THE INFLUENCE OF ENVIRONMENTAL FACTORS ON TASK LOAD AND DRIVING BEHAVIOR: A PRELIMINARY INVESTIGATION
DE INVLOED VAN OMGEVINGSFAKTOREN OP MATEN VOOR TAAKBELASTING EN RIJGEDRAG--EEH VERKENNEND ONDERZOEK
The influence of some static and dynamic factors in the environment on heart rate, heart rate variation, and driving behavior was studied. Subjects drove an instrumented car on three different test routes: town, four-lane motorway with divided traffic lanes, and two-lane highway. Also, subjects drove under two different order conditions. An auditory subsidiary task was used to obtain more information on driving task difficulty. All heart rate measures proved to be sufficiently sensitive to differentiate between driving in town versus driving on the motorway or the highway; static aspects of the environment, such as narrow lane width, showed an effect on heart rate variability. The auditory subsidiary task had an influence on the number of reversals in heart rate and steering signal. Also, there existed some remarkable differences in lateral and longitudinal control between motorway and highway.
