Exploring the future mobility of older people is imperative for maintaining wellbeing and quality of life in an ageing society. The forthcoming level 3 automated vehicle may potentially benefit older people. In a level 3 automated vehicle, the driver can be completely disengaged from driving while, under some circumstances, being expected to take over the control occasionally. Existing research into older people and level 3 automated vehicles considers older people to be a homogeneous group, but it is not clear if different sub-groups of old people have different performance and perceptions when interacting with automated vehicles. To fill this research gap, a driving simulator investigation was conducted. We adopted a between-subjects experimental design with subgroup of old age as the independent variable. The differences in performance, behaviour, and perception towards level 3 automated vehicles between the younger old group (60–69 years old) and older old group (70 years old and over) was investigated. 15 subjects from the younger old group (mean age = 64.87 years, SD = 3.46 years) and 24 from the older old group (mean age = 75.13 years, SD = 3.35 years) participated in the study. The findings indicate that older people should not be regarded as a homogeneous group when interacting with automated vehicle. Compared to the younger old people, the older old people took over the control of the vehicle more slowly, and their takeover was less stable and more critical. However, both groups exhibited positive perceptions towards level 3 automation, and the of older old people’s perceptions were significantly more positive. This study demonstrated the importance of recognising older people as a heterogeneous group in terms of their performance, capabilities, needs and requirements when interacting with automated vehicles. This may have implications in the design of such systems and also understanding the market for autonomous mobility.

与3级自动驾驶汽车互动时,老年人是否应被视为同质人群?

探索老年人的未来流动性对于维持老龄化社会的福祉和生活质量至关重要。即将面世的3级自动驾驶汽车可能会给老年人带来好处。在三级自动驾驶汽车中,在某些情况下,驾驶员可能会完全脱离驾驶,而在某些情况下,驾驶员可能会偶尔接管控制权。现有的有关老年人和3级自动驾驶汽车的研究认为老年人是同一个群体,但尚不清楚不同的老年人亚群在与自动驾驶汽车互动时是否具有不同的性能和看法。为了填补这一研究空白,进行了驾驶模拟器调查。我们采用受试者之间的实验设计,将老年分组作为自变量。效果上的差异 行为,以及年龄较小的老年人群(60-69岁)和年龄较大的老年人群(70岁及以上)之间对3级自动驾驶汽车的感知能力进行了调查。年龄较小的一组(平均年龄= 64.87岁,SD = 3.46岁)中的15名受试者和年龄较大的一组(平均年龄= 75.13岁,SD = 3.35岁)中的24名受试者参加了研究。研究结果表明,与自动车辆互动时,不应将老年人视为同质群体。与年轻的老年人相比,年长的老年人接管车辆的控制更加缓慢,他们的接管不稳定且更为关键。但是,两组都对3级自动化表现出积极的看法,而老年人的看法则明显更积极。这项研究表明,在与自动驾驶汽车互动时,就其性能,能力,需求和要求而言,认识到老年人是异类人群的重要性。这可能会对此类系统的设计产生影响,也可能会影响自动驾驶市场。
