联邦公路管理局（FHWA）提出了公路设计指南，以提高老年驾驶员的安全驾驶能力，但几乎没有经验证据支持这些指南。使用从仪表车辆和道路评价的运动学测量，作者检查了改进与未改进的交叉口的安全效果，在老年人（65-85）和年轻人（25-45）的司机。运动学测量结果表明，4个动作的横向稳定性显着较差的未改进的条件下，和显着更大的速度为改进的条件。行为措施表明，司机有显着较少的错误2改进左转机动，和更少的总错误的整体，与老司机有较高的平均错误数。这些研究结果表明，FHWA的安全道路条件指南导致老年人和年轻人更安全的驾驶。
The Federal Highway Administration (FHWA) proposed highway design guidelines to increase safe driving ability of older drivers, but little empirical evidence exists to support these guidelines. Using kinematics measures from an instrumented vehicle and on-road evaluations, the authors examined the safety effects of improved versus unimproved intersections in older (65–85) and younger (25–45) drivers. Kinematics measures showed that 4 maneuvers had significantly poorer lateral stability for the unimproved conditions, and significantly greater speed for the improved conditions. Behavioral measures showed that drivers had significantly fewer errors for 2 improved left-turn maneuvers, and fewer total errors overall, with older drivers having a higher mean number of errors. These findings suggested that the FHWA guidelines for safe road conditions result in safer driving by older and younger adults.
