Freeway merging of heavy goods vehicles (HGV) is a safety–critical manoeuvre. However, at present, it is largely unknown how HGV drivers perceive and execute the merging manoeuvre, and how current advanced driver support and automation systems (ADAS) contribute. We performed semi-structured in-depth interviews with 15 HGV drivers to assess their visual and cognitive processes while merging, interactions with other road users, and attitudes towards ADAS as a basis for future support and automation system design. Results show that the reported execution of merging varies substantially between drivers. Drivers reported reliance on courtesy of other traffic but stated that car drivers are often causing conflicts, whereas other HGV drivers are more cooperative. Current ADAS were perceived as useful in general, with remarks about misuse and abundance of systems. We recommend the introduction of driver support and automation systems which facilitate cooperative behaviour and support effective communication.

司机如何将重型货车并入高速公路？半结构化面试揭示了沟通和支持的需求

重型货车 (HGV) 的高速公路合并是一项安全关键操作。然而，目前，HGV 驾驶员如何感知和执行合并操作，以及当前的高级驾驶员支持和自动化系统 (ADAS) 如何发挥作用，在很大程度上是未知的。我们对 15 名 HGV 驾驶员进行了半结构化深度访谈，以评估他们在合并时的视觉和认知过程、与其他道路使用者的互动以及对 ADAS 的态度，作为未来支持和自动化系统设计的基础。结果表明，所报告的合并执行在驱动程序之间存在很大差异。司机报告依赖其他交通的礼貌，但表示汽车司机经常引起冲突，而其他 HGV 司机则更合作。目前的 ADAS 被普遍认为是有用的，关于滥用和系统丰富的评论。我们建议引入驾驶员支持和自动化系统，以促进合作行为并支持有效沟通。
