| Abstract |
| Using level-3 automated driving simulation, this study examined the effects of before-after the obstacle avoidance(BOA and AOA, respectively) and driver age group on situation awareness, control transition time, and vehicle control performances. The results can be summarized as follows. First, the situation awareness of the participants was lower in the BOA section compared to the AOA section, and in the older driver group compared to the young driver group, and this tendency was more evident in the BOA section. Second, the control takeover time was significantly slower in the older driver group than in the younger driver group. Third, in all four vehicle control measures, worse performance was observed in the AOA section than in the BOA section, and in the older driver group than in the young driver group, but the difference between age groups in vehicle control performance was larger in the AOA section than in the BOA section. These results suggest that in a situation where the driver takes over control during autonomous driving and avoids obstacles by driving manually, the driver's situational awareness and vehicle control may vary depending on before and after the obstacle avoidance. |
