The purpose of the present study was to gain a better understanding of the types of in-vehicle technologies being used by older drivers as well as older drivers' use, learning, and perceptions of safety related to these technologies among a large cohort of older drivers at multiple sites in the United States. A secondary purpose was to explore the prevalence of aftermarket vehicle adaptations and how older adults go about making adaptations and how they learn to use them. The study utilized baseline questionnaire data from 2990 participants from the Longitudinal Research on Aging Drivers (LongROAD) study. Fifteen in-vehicle technologies and 12 aftermarket vehicle adaptations were investigated. Overall, 57.2% of participants had at least one advanced technology in their primary vehicle. The number of technologies in a vehicle was significantly related to being male, having a higher income, and having a higher education level. The majority of respondents learned to use these technologies on their own, with "figured-it-out-myself" being reported by 25%-75% of respondents across the technologies. Overall, technologies were always used about 43% of the time, with wide variability among the technologies. Across all technologies, nearly 70% of respondents who had these technologies believed that they made them a safer driver. With regard to vehicle adaptations, less than 9% of respondents had at least one vehicle adaptation present, with the number of adaptations per vehicle ranging from 0 to 4. A large majority did not work with a professional to make or learn about the aftermarket vehicle adaptation.
本研究旨在更深入地了解老年驾驶员所使用的车载技术类型，以及他们对这些技术的使用、学习和安全相关认知。这项研究在美国多个地点的大量老年驾驶员中进行。本研究的次要目的是探索售后车辆改装的流行程度，以及老年人如何进行改装以及如何学习使用它们。该研究利用了来自 2990 名参与“Longitudinal Research on Aging Drivers（LongROAD）”研究的参与者的基线问卷数据。研究调查了 15 种车载技术和 12 种售后车辆改装。总体而言，57.2%的参与者在其主要车辆中至少有一种先进技术。车辆中技术的数量与男性、高收入和高教育水平显著相关。大多数受访者自行学习使用这些技术，有 25%-75%的受访者在不同技术之间报告了“自己弄明白的”情况。总体而言，这些技术的使用频率约为 43%，不同技术之间的差异很大。在所有技术中，近 70%的有这些技术的受访者认为这些技术使他们成为更安全的驾驶员。关于车辆改装，不到 9%的受访者至少有一项车辆改装，每辆车的改装数量从 0 到 4 不等。大多数人没有与专业人士合作进行车辆改装或学习有关售后车辆改装。
