Longer-Term Effects of ADAS Use on Speed and Headway Control in Drivers Diagnosed With Parkinson's Disease

<b>Objective:</b> An advanced driver assistance system (ADAS) provided information about speed limits, speed, speeding, and following distance. Information was presented to the participants by means of a head-up display.<b>Methods:</b> Effects of the information on speed and headway control were studied in a longer-term driving simulator study including 12 repeated measures spread out over 4 weeks. Nine healthy older drivers between the ages of 65 and 82 years and 9 drivers between the ages of 68 and 82 years diagnosed with Parkinson's disease (PD) participated in the study. Within the 4 weeks, groups completed 12 consecutive sessions (10 with ADAS and 2 without ADAS) in a driving simulator.<b>Results:</b> Results indicate an effect of ADAS use on performance. Removing ADAS after short-term exposure led to deterioration of performance in all speed measures in the group of drivers diagnosed with PD.<b>Conclusions:</b> These results suggest that provision of traffic information was utilized by drivers diagnosed with PD in order to control their speed.

<b>研究目标：</b>高级驾驶辅助系统（ADAS）可提供限速值、当前车速、超速状态及跟车距离相关信息，并通过平视显示器（head-up display）向受试者呈现上述信息。
<b>研究方法：</b>本研究通过一项为期4周、包含12次重复测量的长期驾驶模拟器实验，探究该类信息对车速与跟车控制的影响。本次研究共招募9名年龄介于65至82岁的健康老年驾驶员，以及9名年龄介于68至82岁的帕金森病（Parkinson's disease，PD）确诊受试者参与实验。在4周的实验周期内，两组受试者共完成12次连续的驾驶模拟器实验场次，其中10次启用高级驾驶辅助系统（ADAS），剩余2次未启用该系统。
<b>研究结果：</b>实验结果表明，高级驾驶辅助系统（ADAS）的使用对驾驶表现存在显著影响。在短期使用该系统后移除ADAS时，帕金森病确诊受试者组的各项车速相关指标均出现驾驶性能下滑。
<b>研究结论：</b>上述结果显示，帕金森病确诊受试者会借助此类交通信息辅助自身控制行驶车速。
