Unlocking Insights from Deceleration Marking Research
This research evaluates the effectiveness of speed reduction markings on highway traffic safety by analyzing real driving behavior. It focuses on the impact of different marking types and key performance parameters (like retroreflectance) on driver prompting and deceleration effects. Using eye movement and electrodermal activity (EDA) data, the study identifies effective marking areas and quantifies speed reduction for various marking configurations. It concludes that combined markings are most effective, and maintaining high retroreflectivity is crucial for driver attention and overall safety.

Understanding Driver Behavior
Understanding driver responses to road markings is crucial for effective highway design. This research utilized advanced physiological monitoring, including eye-tracking technology (fixation, saccade, blink patterns) and electrodermal activity (EDA) detection, to objectively measure drivers' cognitive and emotional states. Eye-tracking reveals where drivers focus their attention and process information, while EDA indicates sympathetic nervous system activity, reflecting psychological arousal and stress levels. This dual approach provides a robust framework to understand how deceleration markings influence drivers' perception, decision-making, and ultimate control over vehicle speed.
Optimizing Marking Types for Speed Control
The study evaluated various deceleration marking types, revealing distinct impacts on driving speed and driver psychology. Longitudinal deceleration markings showed a speed decrease of 4.96%-12.85%, with EDA peaks indicating driver anticipation and response. Horizontal break lines resulted in a higher speed reduction of 11.51%-17.73%, demonstrating a significant stimulating effect. Most notably, combined speed limit markings achieved the highest speed reduction, ranging from 17.78%-21.67%, with strong EDA peaks confirming their powerful stimulating effect. Combined markings are approximately equivalent to the direct summation of the reduction effects of transverse and longitudinal markings.
The Role of Retroreflectivity in Visibility and Attention
The retroreflectivity coefficient, a measure of how effectively road markings reflect light, is critical for visibility and driver attention. The research found that as the retroreflective luminance coefficient decreases, the prompting effect of markings weakens. When retroreflectivity is below national standards, drivers struggle to clearly perceive lane markings. This forces visual focus onto lane lines, diverting attention from other critical information and potentially causing drivers to miss important predictive cues. Maintaining optimal retroreflectivity is therefore essential for effective visual guidance and enhanced highway safety, especially during nighttime or adverse weather conditions.

Case Study: The Critical Role of Retroreflectivity in Driver Attention
Research consistently shows that optimal retroreflectivity of road markings is paramount for driver safety. When retroreflective luminance coefficients fall below standard, drivers struggle to distinguish lane markings, compelling them to focus more intensely on the lines themselves. This increased visual burden can divert critical attention away from other vital road cues and potential hazards. Ensuring proper maintenance of retroreflective markings directly contributes to reducing driver workload, improving real-time decision making, and ultimately enhancing overall highway safety.
