Unsignalized intersections are accident-prone locations due to numerous conflict points and unclear right-of-way. This issue is exacerbated at night when road markings become less visible, leading to increased accident rates. Self-luminous road markings, a new type of proactive traffic safety control facility, have garnered increasing attention and are being gradually promoted due to their intelligent, stable brightness and variable characteristics. To explore the warning effect of self-luminous road markings at unsignalized intersections at night, this study designed three types of warning schemes: continuous-illuminating pedestrian crosswalk advance warning marking (CPWM), continuous-illuminating yield text advance warning marking (CYWM), and transition-illuminating pedestrian crosswalk advance warning marking (TPWM). Based on previous research, nine indicators were selected for comprehensive evaluation from the perspectives of driver's operating, visual characteristics, and psychology. Finally, an entropy-based matter-element model was constructed to comprehensively evaluate the warning effect. The results show that the CYWM and CPWM schemes can help drivers effectively reduce the mean speed and potential lateral conflict risk at intersections, enhancing drivers' awareness of road environment information. However, the TPWM scheme had adverse effects due to greater visual stimulation. The effectiveness of the three schemes ranks from high to low as CYWM, CPWM, and TPWM. This study confirms that self-luminous road markings are effective at intersections, providing new insights for infrastructure upgrades and offering a general framework for evaluating the effectiveness of traffic safety facilities.
无信号控制的交叉路口由于冲突点众多且路权不明确，是事故多发地段。夜间，道路标线可视性降低，这一问题会更加严重，导致事故率上升。自发光道路标线作为一种新型的主动式交通安全控制设施，因其智能、稳定的亮度和可变特性而受到越来越多的关注，并正在逐步推广。为了探究自发光道路标线在夜间无信号控制交叉路口的警示效果，本研究设计了三种警示方案：连续发光人行横道前置警示标线（CPWM）、连续发光让行文字前置警示标线（CYWM）和过渡发光人行横道前置警示标线（TPWM）。基于以往研究，从驾驶员操作、视觉特性和心理等角度选取了九个指标进行综合评价。最后，构建了基于熵权的物元模型来综合评价警示效果。结果表明，CYWM和CPWM方案有助于驾驶员有效降低交叉路口的平均车速和潜在横向冲突风险，增强驾驶员对道路环境信息的感知。然而，TPWM方案由于视觉刺激较大产生了不利影响。三种方案的有效性从高到低依次为CYWM、CPWM、TPWM。本研究证实了自发光道路标线在交叉路口是有效的，为基础设施升级提供了新的见解，并为评估交通安全设施的有效性提供了一个通用框架。
