IN-VEHICLE AUDITORY DISPLAY OF SYMBOLIC INFORMATION

This paper reports on an experiment which investigated the effectiveness of presenting drivers with verbal information informing them of symbolic road signs as compared to graphic visual images of the signs. The experiment involved road signs which contained either symbolic or text-based messages. Participants were asked to determine if the displayed message matched a projected sign image after being presented with visual or auditory information. Measurements were assessed for performance accuracy and recognition times. It was found that driver response time was longer for text-based messages than symbolic messages but that this was not affected by the type of display used to present the image. The researchers found that presenting drivers with verbal information of symbolic road signs was as effective as presenting them with graphic visual images of the signs.
