CAUSES AND IMPACTS OF DRIVER DISTRACTION: A DRIVING SIMULATOR STUDY

Abstract: 

The objective of this research is the analysis of causes and impacts of driver distraction. Distraction sources may be exogenous (use of mobile phone, conversation with passengers etc.) or endogenous (mild pathological conditions, e.g. mild cognitive impairment, sleep disorders, early Alzheimers or dementia etc., as well as personality elements, e.g.impulsivity). These are examined jointly for the first time internationally. A driving simulator experiment is carried out, comprising a medical/neurological and neuropsychological evaluation of the participants, and a set of driving tasks for different scenarios.

The participants comprise two distinct groups from the general population: a group of individuals with mild pathological conditions, and a group of healthy individuals. Models of driver distraction are then developed in order to identify and rank the causes of distraction. Separate analyses of neurological, neuropsychological and exogenous distraction sources is initially carried out, followed by a combined assessment of all distraction causes.

Models of driver behavior and safety are also developed, in order to quantify the impacts of distraction. Driver speed and vehicle position on the lane are modeled in relation to distraction, road / traffic conditions, driver characteristics etc. Moreover, driver reaction time and accident probability are modeled in relation to the above variables, within the occurrence of unexpected incidents. A synthesis on driver distraction mechanisms is carried out, in which the causes and impacts of driver distraction are integrated both qualitatively (i.e. chains of events, distracted driving patterns) and quantitatively (i.e. magnitude and relative importance of causes and impacts).

The analysis of causes and impacts of driver distraction allows for the identification of measures for the improvement of driver behavior e.g. restrictive measures, information campaigns, medical and psychological monitoring of drivers etc.
