Abstract

The global population of licensed older drivers has experienced a notable increase. It is known that physical and cognitive changes are inherent to the aging process. Sensory, cognitive, and physical deficiencies among older adults are associated with poor driving performance and crashes. The impact of cognitive and physical impairments on the fitness to drive remains insufficiently understood in many scenarios, particularly in Brazil. This study evaluated physical and cognitive functions of community-dwelling Brazilian older drivers in domains relevant to driving, and associated these findings with the performance in a standardized on-road test in real urban traffic conditions. A sample of 138 volunteers (mean of 70.7 years) was tested for physical and cognitive functionalities, and then assessed by driving a pre-defined route of 10 km on urban roads. In this study, there was no association between physical functions and the general aptitude for driving, albeit a slower walking speed was found associated with more errors at intersections and lane merging. Regarding cognition, an overall poorer on-road driving performance was associated with lower scores in executive functions, especially in the time management ability, while errors in specific maneuvers were associated with declines in attention capacity, cognitive flexibility, and visuospatial organization ability.

巴西老年人的认知和身体特征与道路驾驶表现的关系

全球持有驾照的老年司机人数显著增加。众所周知，身体和认知的变化是衰老过程所固有的。老年人的感官、认知和身体缺陷与驾驶表现不佳和撞车事故有关。认知和身体障碍对驾驶能力的影响在许多情况下仍未得到充分了解，尤其是在巴西。本研究评估了居住在巴西社区的老年司机在驾驶相关领域的身体和认知功能，并将这些发现与在真实城市交通条件下的标准化道路测试中的表现联系起来。138名志愿者（平均年龄70.7岁）接受了身体和认知功能测试，然后通过在城市道路上行驶预先设定的10公里路线进行评估。在这项研究中，身体机能和一般驾驶能力之间没有联系，尽管较慢的步行速度被发现与十字路口和车道合并时更多的错误有关。在认知方面，整体较差的道路驾驶表现与执行功能，特别是时间管理能力得分较低有关，而特定操作错误与注意力能力，认知灵活性和视觉空间组织能力下降有关。

期刊介绍： Transportation Research Part F: Traffic Psychology and Behaviour focuses on the behavioural and psychological aspects of traffic and transport. The aim of the journal is to enhance theory development, improve the quality of empirical studies and to stimulate the application of research findings in practice. TRF provides a focus and a means of communication for the considerable amount of research activities that are now being carried out in this field. The journal provides a forum for transportation researchers, psychologists, ergonomists, engineers and policy-makers with an interest in traffic and transport psychology.
