- Sleep related crashes have received increasing attention over the past decade. Driver support systems that are able to detect sleepiness and warn the driver could be a potential countermeasure to reduce sleepiness related crashes. The aim of this study was to evaluate a warning system in an experimental investigation performed in a real time car driving application. An additional aim was also to examine the suitability of using an experimental vehicle at test track for evaluation of a sleepiness warning system. The modalities used for warning was a combination of sound, vibrations in belt and spoken messages. In addition a hand worn confirmation button was used. In total 40 participants drove at a closed test track during night (00h-05h). They were instructed to sleep between 01.00 and 07.00 for two nights prior to the night of the experiment. The design of the study was a between group, with 10 participants in each group. The four different groups experienced one of the following: A: No warning - baseline; B: SENSATION warning system with an early trigger; C: SENSATION warning system with a late trigger; D: Feedback (DMS - Siemens) and warning with a late trigger. The trigger of the warnings was based on observer registrations of the driver and driver behaviour. The drivers were instructed to drive a distance of 110 kilometres. The car was a Volvo 850, equipped with sensors in order to measure driving behaviour (lateral position, speed, steering wheel angle). As sleepiness indicators blink duration was used (mean and sd), measured with EOG. After the drive the participants answered a questionnaire. The experiment focused on comprehension, usability, effectiveness, and acceptance.
