Abstract

In this study, we measured and analyzed elderly drivers' behavior (gaze position) in real traffic conditions including traffic scenes such as turning left/right busy intersections, driving narrow residential streets, etc. using eye camera to investigate when and how elderlies behave riskily. By comparing measured gaze position data of 24 elderlies and those of 14 non-elderlies, we found out that elderlies performed significantly less scanning behavior than non-elderlies when (1) turning right at a busy intersection where driver should simultaneously pay attention to multiple vehicles, bicycles and pedestrians around, (2) passing through an intersection of narrow residential streets without any traffic sign indicating location/risk of the intersection. We also found that elderlies tended not to check safety of backside of vehicle while braking as he approached to an intersection with stop sign. In addition to these, the number of elderlies' visual confirmation to the overhead mounted stop sign is significantly less than non-elderlies'.
