Abstract [en]

Visual warnings are used to help prevent drivers from making unnecessary mistakes, but if warnings are not noticed in time they are useless. Today warnings are most often placed in front of the driver and behind the steering wheel, but this may not be the most conducive location for all warnings. An unexpected warning can increase the risk for distraction, just as a poorly placed warning can, which, in turn, could decrease the driver's chances to react correctly for what is warned for. A dilemma for traffic safety experts is how to expand the ways warnings can be presented to the driver without negatively affecting driver performance. In this study a questionnaire, 142 respondents, was used to find out driver's perception to in-vehicle warnings and where they preferred those to be found; in a head-up display (HUD), head-down display (HDD), infotainment (IF), or in a center-stack (CS). Twenty respondents in a high fidelity fixed base simulator compared and evaluated how different warnings placements were responded to and how they affected normal driving in two different warning layouts. Ten respondents were simultaneously presented a warning in the HUD and HDD and ten in either the HUD, HDD, IF, or the CS. Response times (via focal vision), driving performance, and subjective responses were measured, which included measuring the cognitive workload with the Driving Activity Load Index (DALI). The results showed that the respondents of the HUD/HDD group almost exclusively used the HUD and all respondents stated that the HUD was best fitted for important warnings. However, more transparent groupings of warnings were requested as a separation of warnings based on their level of importance. Moreover, the drivers performed best when the warnings were presented in the HUD and IF locations
