Observing the driver's behavior by reproducing traffic accidents and conflict situations are effective in investigating the causes of accidents. In previous studies, driving simulators were often used in reproducing accident and conflict scenes, but such systems had difficulties in reproducing realistic situations. Therefore, a new instrumented vehicle, named JARI-ARV (Japan Automobile Research Institute - Augmented Reality Vehicle), was developed to reproduce realistic traffic accident and conflict scenarios without putting the driver at risk of an actual collision. JARI-ARV was equipped with three Liquid - Crystal - Displays (LCD) and three video cameras in front of the driver. When we want to reproduce a critical scene, computer graphics (CG) are superimposed on top of the real frontal image captured by the video cameras. These CGs are adopted from Augmented Reality (AR), and gives the impression as though they are on a test field. In this paper, we confirmed the acceptability and controllability in some driving situation, by comparing JARI-ARV with a standard vehicle. As a result, driver's behaviour in right turns and reaction to pedestrians were almost the same between JARI-ARV and the standard vehicle. However drivers found it difficult to stop at a stopline while driving JARI-ARV. In addition, the driver's reaction time for a pedestrian appearing behind a wall was almost the same between JARI-ARV and the standard vehicle.
