摘　　要：快速路交织区主动管控策略对提高快速路运行效率、改善行车环境、提升行车安全等具有重要意义。主动发光标线是一种新型道路交通安全主动管控设施,因其智能可控、虚实变换、应急预警等功能特点,越来越受到关注和逐步被推广应用。为探究发光标线这一新型道路标线在快速路交织区对行车安全的作用效果,从驾驶人角度出发,基于驾驶模拟试验,分析发光标线对驾驶行为的影响特征,评估发光标线作用效果。通过设计夜间环境下普通标线和发光标线两种驾驶模拟试验场景方案,获取驾驶行为数据,从行车安全性、舒适性和驾驶人操纵表现3方面选取速度标准差、横向偏移标准差、纵向加速度均方根值、加速度标准差、平均速度、油门功效6项指标构建评价指标体系。进一步分析各项指标在不同标线场景下的差异显著性及效应量水平,最后采用可拓物元方法构建综合评价模型,对比两种标线方案的作用效果。研究结果表明:发光标线对交织区及临近交织区路段驾驶行为特性具有较显著的影响,发光标线下驾驶人横向位置感知和操纵水平提升,车速调控能力提高,车辆行驶更加平稳。基于可拓物元模型综合评价结果表明,在快速路交织区及临近交织区路段发光标线作用效果均优于普通标线,有利于提升快速路交织区行车安全。The active management and control strategy in the weaving section of expressways plays a crucial role in enhancing operational efficiency and improving driving safety.Self-luminous road marking is a new type of road traffic safety active control facility.Because of its intelligent control,virtual and real transformation,emergency warning and other functional characteristics,it has attracted more and more attention and gradually promoted and applied.In order to explore the effect of the new road marking in the expressway weaving area,based on the driving simulation test,this paper analyzed the influence characteristics of self-luminous road marking on driving behavior from the perspective of drivers and evaluated the effect of self-luminous road marking.Two simulation scenarios were designed:one with conventional road markings and the other with self-luminous road markings under nighttime conditions.Driving behavior data were collected,and six indicators were selected to construct an evaluation system,focusing on driving safety,comfort,and driver control performance.These indicators include standard deviation of speed,standard deviation of lateral position,root mean square of longitudinal acceleration,standard deviation of acceleration,mean speed,and throttle effectiveness.Further analysis was conducted to examine the significance of differences and effect size levels of various indicators under different road marking scenarios.Finally,an extension matter-element model was applied to construct a comprehensive evaluation model to compare the effects of the two road marking schemes.The results indicate that self-luminous road markings significantly influence driving behavior characteristics in weaving sections.Under the self-luminous marking condition,drivers’lateral position perception and control levels is improved,speed regulation ability is increased,and vehicle movement becomes more stable.The comprehensive evaluation based on the extension matter-element model shows that self-luminous road markings are more
