Abstract: This article presents a computational modelling approach for negative effects simulation of visual distraction while driving. In order to investigate these effects, an experiment was implemented on a driving simulator. Empirical data collected shows that visual distraction impacts the driving performance at perceptive and behavioural levels. The aim of this study was also to investigate and to simulate the distractive effects on driver's mental models. Indeed, driving decisions and behaviours are based on a temporal-spatial mental model, corresponding to the driver's situational awareness (SA). In case of visual distraction requiring off-road glance, mental model updating may be imperfectly done and driver's actions are thus based can differ on the situational reality. From these, a perception module, interfaced with cognitive functions of a computational model named COgnitive Simulation MOdel of the DRIVEr, was developed and implemented for simulating visual distraction effects and human errors risks at perceptive, cognitive and behavioural levels.
