Safety effects of in-car telematics : a checklist : determining possible abverse effects of telematic systems on the driving task. On behalf of the Dutch Ministry of Transport, Public Works and Water Management, Transport Research Centre AVV.

This report is part of a project aimed at investigating the road safety effects of various telematics applications intended to support the driver. An attempt is made: (1) to reorder a checklist according to the aspects of visual, mental and physical task load; and (2) to assemble basic material necessary to extend the checklist with aspects of counterproductive behavioural adaptation. An expert meeting was organised to obtain directives on which way to go with counterproductive behavioural adaptation. The results of this meeting were twofold: (i) a structuring matrix, based upon characteristics of Advanced Transport Telematics (ATT) applications and characteristics of the traffic environment; and (ii) a list of psychological mechanisms relevant to behavioural adaptation. Subsequently, it has been attempted to interpret relations between the items of the latter list using the `situation awareness' model. According to this model, it is concluded that schemata (models of the relation between surrounding phenomena), scripts (`automated' sequences of actions) and the ways these are generated or changed, play an important role in behavioural adaptation. The report concludes with a recommendation for a `three-step procedure' to obtain a checklist on counterproductive behavioural adaptation. (A) See also IRRD 892117.
