    Area of Science:

    • Human-computer interaction
    • Cognitive psychology
    • Traffic safety

    Background:

    • Drivers must process visual information from traffic signs and advertisements.
    • Peripheral vision and eye fixations are crucial for information uptake.
    • Roadside advertisements can interfere with driver attention and perception.

    Purpose of the Study:

    • To investigate how drivers perceive traffic signs and roadside advertisements.
    • To determine the relationship between fixation duration and perception accuracy.
    • To assess the disruptive effect of advertisements on traffic sign perception.

    Main Methods:

    • Simulated driving experiment with color slides of highway scenes.
    • Measured eye fixations, fixation times, and conscious perceptions.
    • Analyzed the impact of peripheral vision and fixation duration on perception.

    Main Results:

    • Perception occurred through fixation and peripheral vision; fixation did not always lead to perception.
    • Increased fixation time correlated with higher correct perception rates.
    • Advertisements in the same visual field as traffic signs hindered sign perception, especially with poor ad design causing prolonged fixation.

    Conclusions:

    • Fixation duration is critical for accurate perception of traffic information.
    • Roadside advertisements can negatively impact driver's ability to process traffic signs.
    • Poorly designed advertisements exacerbate perceptual interference due to extended fixation times.
