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.

与不熟悉的交通标志相关的驾驶员眼睛运动:眼睛跟踪研究。

交通标志是交通控制计划的组成部分,它们为道路使用者提供有关即将发生的情况的必要信息。本文旨在考察不同国家/地区使用的交通标志图像的理解水平,并跟踪参与者遇到陌生标志时的眼动情况。Tobii眼动跟踪眼镜用于跟踪熟悉和不熟悉的交通标志之间的视线差异。我们的发现表明,标志的特征(例如标志上的信息量)和观察者对标志含义的了解对眼睛的行为有重大影响。包含更多信息(载有更多内容)且对参与者不熟悉的标牌系统地产生了最长的总体注视和平均注视以及凝视时间。
