道路车辆. 交通信息和控制系统. 评估驾驶中认知负荷注意力影响的检测反应任务(DRT

[中文适用范围]： 本文件规定了检测-反应任务（DRT）的测试方法，主要针对评估认知负载对注意力的影响，特别是涉及视觉-手动、语音或触觉界面的副驾驶任务。DRT用于衡量在执行副驾驶任务时，注意力资源如何受到认知负载的影响。这些任务可能包括操作媒体播放器、接打电话、阅读路边广告牌以及在导航系统中输入目的地等行为。本文件不适用于测量主要驾驶任务（如维持车道位置和车距）的需求，但DRT方法仍可用于评估这些任务的认知影响。本文件适用于原始设备制造商（OEM）、 aftermarket 车载系统、固定安装和便携式系统。需要注意的是，DRT方法旨在测量注意力资源的变化，并不直接关联碰撞风险。由于DRT依赖手动响应（如按钮按下），对于需要频繁手动输入的任务，DRT结果可能更多地反映操作冲突，而非实际认知负载。因此，在解释时需谨慎。本文件定义了三种版本的DRT，具体选择取决于研究目的和测试条件。本文件未规定特定实验协议或统计方法，但在正文和附录中提供了指导和实践示例。 [外文原描述]： ISO 17488:2016 provides a detection-response task mainly intended for assessing the attentional effects of cognitive load on attention for secondary tasks involving interaction with visual-manual, voice-based or haptic interfaces. Although this document focuses on the assessment of attentional effects of cognitive load (see Annex A), other effects of secondary task load may be captured by specific versions of the DRT, as further outlined in Annex B. Secondary tasks are those that may be performed while driving but are not concerned with the momentary real-time control of the vehicle (such as operating the media player, conversing on the phone, reading road-side commercial signs and entering a destination on the navigation system). NOTE According to this definition, secondary tasks can still be driving-related (such as in the case of destination entry). ISO 17488:2016 does not apply to the measurement of primary (driving) task demands related to the momentary real-time control of the vehicle, such as maintaining lane position and headway or responding to forward collision warnings. However, this does not preclude that the DRT method, as specified in this document, may be adapted to measure such effects. ISO 17488:2016 applies to both original equipment manufacturer (OEM) and after-market in-vehicle systems and to permanently installed, as well as portable, systems. It is emphasized that, while the DRT methodology defined in this document is intended to measure the attentional effects of cognitive load, it does not imply a direct relationship between such effects and crash risk. For example, taking the eyes off the road for several seconds in order to watch a pedestrian may not be very cognitively loading but could still be expected to strongly increase crash risk. Furthermore, interpret DRT results cautiously in terms of demands on a specific resource, such as cognitive load. Specifically, if the goal is to isolate the effect related to the cognitive load imposed by a secondary task on attention, avoid overlap with other resources required by the DRT (e.g. perceptual, motor, sensory or actuator resources). A particular concern derives from the fact that the DRT utilizes manual responses (button presses). Thus, for secondary tasks with very frequent manual inputs (on the order of one or more inputs per second), increased response times on the DRT may reflect this specific response conflict (which is due to the nature of the DRT) rather than the actual cognitive load demanded by the task when performed without the DRT (i.e. alone or during normal driving; see Annex E). Thus, for such response-intensive tasks, DRT results are interpreted with caution. This document defines three versions of the DRT and the choice of version depends critically on the purpose of the study and the conditions under which it is conducted (see Annexes A and B for further guidance on this topic). ISO 17488:2016 specifically aims to specify the detection-response task and the associated measurement procedures. Thus, in order to be applicable to a wide range of experimental situations, this document does not define specific experimental protocols or methods for statistical analysis. However, some guidance, as well as examples of established practice in applying the DRT, can be found both in the main body of this document and in the annexes (in particular Annexes C and E).
