Abstract
Japan is becoming a super-aging society, where there are concerns regarding traffic accidents caused by elderly drivers. This study aimed to investigate the effectiveness of a human–machine interface (HMI) for assessing elderly drivers’ behaviour. The drivers’ behaviour was investigated when a pedestrian crossed while the drivers turned right at intersections and drove on straight roads, with vehicles travelling in the left lane. We investigated 16 elderly participants by using a driving simulator. The results indicated that the display of pedestrian information increased the closest distance of the vehicle to the crossing pedestrian. Moreover, time to collision increased under conditions where there were three preceding vehicles turning right at an intersection or driving straight on a straight road. In the questionnaire, most participants answered that the HMI was helpful. These findings can serve as the basis while designing an HMI that encourages elderly drivers to notice pedestrians.
