“…(3) Processing of sign information stage In the processing of sign information stage, the processing and cognitive ability of information (PCAI) are the key issues [79]. The long average duration of AOI (ADA) of gaze behavior indicates that this area contains complex information, and recognition is difficult [61].…”

Efficient sign layouts play a crucial role in guiding driving in underground construction caverns and enhancing transportation safety. Previous studies have primarily focused on evaluating drivers’ gaze behavior in tunnels to optimize individual traffic sign layouts. However, the lack of a theoretical framework for visual perception of visual capture and information conveyed by sign groups hinders the measurement of drivers’ comprehensive visual perception and the layout optimization of sign groups. To address this gap, this study introduces a calculation method for sign group information volume and a visual cognition model, establishing a comprehensive evaluation approach for sign group visual cognition. Eye movement data, collected using eye-tracking technology, were utilized to evaluate the comprehensive visual perception and optimize the layout of sign groups. The findings indicate that a low information volume fails to enhance recognition ability and alleviate the psychological burden. Conversely, excessive information may result in overlooking signs positioned on the left and top. Furthermore, drivers are unable to improve cognitive efficiency and driving safety even with self-regulation when faced with an information volume exceeding 120 bits within a 100 m span. Overall, this study demonstrates the effectiveness of the proposed method in promoting the long-term safety effect of temporary signage layouts in underground construction areas.

“…According to [51,52], a threatening sign can be an advertisement with a lot of content, as well as one that strongly engages attention, cognitive resources, and arouses emotions that affect information processing. Located near the road, signs with variable content, also have to transmit relevant to safety [53].…”

Man is the most unreliable and at the same time the least understood element in the driver-vehicle-environment system. Many of the factors affecting the driver have been identified in detail. Taking into account the social and mental changes in societies, however, it turns out that what once could be considered harmful, today thanks to new solutions is acceptable. At the same time, due to the dynamics of technological development, new solutions continue to emerge, which, in a situation of improper use, may carry new, hitherto unrecognized dangers in traffic. Therefore, tests related to the determination of factors determining driver behavior are still described in the literature. They are made for different nations, ages and genders of drivers. This article reviews the basic selected factors affecting driver behavior. These factors can directly affect the risk of a traffic collision or accident. While driving, a driver is exposed to a number of stimuli that cause him to become distracted.
