46 participants (24 younger and 22 older) completed at least one out of four simulated drives designed to test the effectiveness of an Adaptive Lane Deviation Warning (LDW) system, and they drove through both a warnings-on and warnings-off version of each drive. Findings showed that LDW was effective in reducing reaction time for lane deviation corrections for both older (by 1.2 seconds) and younger drivers (by 1.6 seconds). The older and younger drivers did not differ in correction RTs when the warnings were turned off. But older drivers showed slower correction RTs than younger drivers in the warning-on drives. The data indicate that these benefits were specific to LDW rather than general improvement in driving performance. Cognitive processing speed emerged as a particularly robust predictor of benefits from the LDW compared to other domains of cognitive function.
46名参与者（24名年轻人和22名年长者）完成了旨在测试自适应车道偏离预警（LDW）系统有效性的四项模拟驾驶中的至少一项，并且他们在每个驾驶的预警开启和预警关闭版本中都进行了驾驶。研究结果表明，LDW在减少年长者（减少1.2秒）和年轻驾驶者（减少1.6秒）的车道偏离校正反应时间方面是有效的。当预警关闭时，年长者和年轻驾驶者在校正反应时间上没有差异。但在预警开启的驾驶中，年长者的校正反应时间比年轻驾驶者慢。数据表明，这些益处是LDW特有的，而非驾驶性能的普遍改善。与认知功能的其他领域相比，认知处理速度成为LDW益处的一个特别有力的预测指标。
