摘要

To address the problem of poor nighttime visibility of conventional pavement markings, this study developed a long-persistence self-luminous pavement marking (SLPM) using rare-earth strontium aluminate as the luminescent material. A driving simulator-based virtual environment was employed to evaluate the visual guidance performance of standard and self-luminous markings on both straight and curved highway segments. The analysis focused on gaze behavior indicators, including visual scanning time, scanning angle, and fixation stability. Results show that the long-persistence SLPM markedly enhances drivers’ visual adaptability under low-visibility conditions. Drivers’ visual scanning times were primarily concentrated within the 0–30ms range, with scanning angles between 2° and 4°, while the frequency of scanning was notably lower than that for standard markings, indicating more stable and efficient information acquisition.These findings demonstrate that self-luminous markings can effectively improve nighttime visual guidance, providing theoretical and practical support for the broader implementation of long-persistence luminescent technologies in roadway design.
