背景驾驶是一项复杂的任务，很难完全客观地描述或盲目地描述。本研究的主要目的是确定全球定位系统（鳃）和视频技术的有用性，研究与年龄相关的驾驶差异。在这项研究中，GPS被用来确定位置。速度和加速度的车辆，由不同年龄的受试者驾驶，而视频片段被用来提供它的详细背景下的驱动器。24名受试者中，年轻人（20 ~ 29岁，n = 6）、中年人（30 ~ 04岁，n = 8）和老年人（65岁及以上，n = 10）驾驶自己的车辆在30 km的各种道路上行驶，并配备GPS接收器和摄像机进行记录。全球定位系统和视频数据相结合，可以确定许多与年龄有关的驾驶差异。派年轻的受试者开车更快，有更短的减速距离和时间，以及更短的加速时间。年轻受试者的违规扣分数量也要高得多，主要是由于超速、在停车标志处没有完全停车以及跟得太近。虽然老年受试者有较少的扣分，他们往往比年轻受试者作出不同类型的错误，包括没有停止在所有的停止标志和转弯错误。全球定位系统和视频技术为评估与年龄有关的驾驶表现提供了新的机会。
Background. Driving is a complex task that is difficult to fully characterize objectively or in it blinded fashion. The main objective of this study was to determine the usefulness of the global positioning system (Gills) and video technology for examining age-related differences in driving. In this study, GPS was used to determine the position. velocity, and acceleration of a vehicle, driven by subjects of different ages, while video footage was used to provide it detailed context of the drive.Methods. Twenty-four subjects who were young (20 to 29: n = 6), middle-aged (30 to 04 n = 8), and older (65 years of age and older n = 10) drove their own vehicles on a 30-km route of various types of roads, with a GPS receiver and video camera recording.Results. The combination of GPS and video data allowed for the determination of many age-related driving differences. Pie young subjects drove faster, had a shorter deceleration distance and time, as well as a shorter acceleration time. Young subjects also had a substantially higher number of infraction demerit points primarily due to speeding, not stopping fully at stop signs, and following too closely. Although the older subjects had a smaller number of demerit points assessed, they tended to make different types of errors than the young subjects including not stopping at all at a stop sign and turning errors.Conclusions. GPS and video technology offer new opportunities for the assessment of age-related driving performance.
