研究人员对有碰撞风险的老年人（n = 645）的5年驾驶习惯轨迹进行了研究。性能指标包括有用视场（UFOV）。无运动视觉知觉测试，快速行走和脚轻拍。自我报告测量包括人口统计和驾驶习惯问卷。纵向随机效应模型显示，与风险较低的参与者相比，基于UFOV的有后续碰撞风险的驾驶员对驾驶的调节更强。危险组在基线时存在限制驾驶，并且在控制基线差异的纵向轨迹中观察到。结果表明，随着时间的推移，有随后撞车风险的人越来越多地限制了他们的驾驶。尽管有这种自我调节，但在更大的样本中，这些老年司机随后发生过失撞车的可能性是前者的两倍。结果表明，在有碰撞风险的老年驾驶员中，自我调节是一种不足以消除增加的碰撞风险的补偿方法。UFOV是视觉意识公司的注册商标。
Five-year driving habit trajectories among older adults (n = 645) at-risk for crashes were examined. Performance measures included Useful Field of View (UFOV). Motor-Free Visual Perception Test, Rapid Walk, and Foot Tap. Self-report measures included demographics and the Driving Habits Questionnaire. Longitudinal random-effects models revealed that drivers at-risk for subsequent crashes, based upon UFOV, regulated their driving more than the lower-risk participants. Restricted driving was present at baseline for the at-risk group and was observed in longitudinal trajectories that controlled for baseline differences. Results indicate that persons at-risk for subsequent crashes increasingly limit their driving over time. Despite this self-regulation, a larger sample of such older drivers was twice as likely to incur subsequent at-fault crashes. Results suggest that self-regulation among older drivers at-risk for crashes is an insufficient compensatory approach to eliminating increased crash risk.UFOV is a registered trademark of Visual Awareness, Inc.
