Title:

Validation of Design Criteria for In-Vehicle Collision Warnings

Accession Number:

Abstract:

Despite recent physical and technological advances in vehicle safety, automobile accidents remain one of the leading causes of death, particularly among young people. As automation allows for more control of non-critical functions by the vehicle, the potential for distraction among drivers also increases. It is, therefore, as important as ever that in-vehicle safety-critical interfaces, such as collision avoidance systems, are intuitive and unambiguous when presenting information to the driver. To this end, the current study aimed to validate previously defined acoustic criteria for use in forward collision warning systems. The current study used a motion-base driving simulator to assess the effectiveness of two warnings, one which met all criteria and one which did not, as well as a no warning control in the context of a lead-vehicle following task in conjunction with a distractor task, and collision event. Results indicate that participants receiving a warning which meets all criteria had improved outcomes relative to participants receiving no warning on their first exposure. Responses to consistently good warnings improved with subsequent exposures whereas results suggest that participants receiving the warning which met only some criteria performed more poorly with increased exposure, and that the inclusion of a poor warning or variable warnings may negate the effects of learning shown by participants who received consistently good warnings or even no warning at all. Findings from this study show support for previous, rating-based, subjective warning design studies. Implications for collision avoidance system design are discussed.
