Traffic signs are an integral part of the traffic control plan and they provide road users with necessary information on the upcoming situation. This paper aims to examine the level of understanding of traffic sign imagery used in different countries and to track participants' eye movement when they encounter unfamiliar signs. Tobii eye tracking glasses were used to track gaze differences between familiar and unfamiliar traffic signs. Our findings show that sign characteristics (such as the amount of information on the sign) and the observer's knowledge of the sign meaning have a significant impact on eye behaviour. Signs containing more information (loaded with more content) and unfamiliar to the participant systematically produced the longest overall and average fixations and gazing duration. Given that longer gaze time for unfamiliar traffic signs presents a potential traffic hazard, we evaluated the need for standardization of traffic signs.
交通标志是交通管制计划的一个组成部分，它们为道路使用者提供有关即将出现的情况的必要信息。本文旨在检查不同国家对交通标志图像的理解程度，并跟踪参与者在遇到不熟悉的标志时的眼动情况。使用 Tobii 眼动追踪眼镜来跟踪熟悉和不熟悉的交通标志之间的注视差异。我们的研究结果表明，标志特征（如标志上的信息量）和观察者对标志含义的了解对眼动行为有重大影响。包含更多信息（内容更丰富）且对参与者不熟悉的标志会系统地产生最长的总注视时间和平均注视时间。由于不熟悉的交通标志的注视时间较长可能带来潜在的交通危险，因此我们评估了交通标志标准化的必要性。
