The effects of conveying declarative knowledge on user attitudes and driving performance when using a conditional driving automation
通过驾驶模拟器实验，研究了向用户传达陈述性知识（知道什么）对驾驶自动化使用态度和表现的影响，发现指导能提高安全接管率，尤其对老年驾驶员有益。
This study explored a challenge of incorporate declarative knowledge—know what—to driving automation’s user education. We focused on an improvement of user attitudes and trust that would contribute to user comprehension and performance, particularly in elderly. A three-factor (instruction, age, test scene) mixed-effects driving-simulator experiment was designed. Twenty-six young (< 55 years old) and 24 elderly (≥ 65 years old) were randomly divided into instructed and uninstructed groups. The results demonstrated that the instruction contributed a 10.5% increase in safely taking over car control and encouraged users to understand how to use a system. Meanwhile, instructed drivers appeared less hesitant to resume control from the system, particularly elderly drivers. However, no significant effect was shown on the response time and steering behaviour. These findings can be used to develop more efficient public education, particularly for the elderly, which is expected to advance user comprehension and operation of driving automation.
