The assistance and autonomous performance of overtaking manoeuvres can offer significant safety benefits. The impact of driving context on perceived risk emphasises the benefits of using contextual information to adjust the manoeuvring behaviour. This paper follows a mixed approach, addressing two main objectives: identifying factor combinations related to overtaking crashes (objective risk) and exploring their relationship to perceived risk. Factor combinations were extracted from a multi-year dataset, acquired from the UK in-depth study RAIDS (Road Accident In-depth Studies). Selected factors were used to create motorway overtaking scenarios with different manoeuvring behaviour (pull-out distance, manoeuvre duration, speed) and driving context (day/night, overtaking car/truck), while 237 participants assessed their impact on perceived risk through an online survey. The findings highlight the strong impact of manoeuvre characteristics on perceived risk, mediated or intensified by the driving context. Long pull-out distance and short manoeuvre duration time were preferred; under night conditions, short pull-out distances were perceived as riskier compared to daytime, while the opposite effect appeared for high speed, which was considered safer. The results can inform future research on motorway overtaking safety perception and acceptability, as well as the design of systems that assist or autonomously perform overtaking. Specifically, they can be used as guidelines for incorporating context related information to adjust overtaking behaviour according to user preferences and create a positive passenger experience.

超车操作的辅助和自主性能可以提供显着的安全优势。驾驶环境对感知风险的影响强调了使用环境信息来调整操纵行为的好处。本文采用混合方法，解决两个主要目标：确定与超车事故（客观风险）相关的因素组合，并探索它们与感知风险的关系。因子组合是从多年数据集中提取的，该数据集是从英国深入研究 RAID（道路事故深入研究）获得的。选定的因素用于创建具有不同操纵行为（拉出距离、操纵持续时间、速度）和驾驶环境（白天/黑夜、超车/卡车）的高速公路超车场景，237 名参与者通过在线调查评估了他们对感知风险的影响。研究结果强调了操纵特征对感知风险的强烈影响，由驾驶环境介导或强化。首选拉出距离长、机动持续时间短；在夜间条件下，与白天相比，较短的拉出距离被认为风险更大，而在被认为更安全的高速时则出现相反的效果。结果可以为高速公路超车安全感知和可接受性的未来研究，以及辅助或自动超车系统的设计提供信息。具体来说，它们可以用作结合上下文相关信息的指南，以根据用户偏好调整超车行为并创造积极的乘客体验。
