针对长余辉道路标线材料实际应用效果评估困难的问题，本研究通过室内实验测定了长余辉道路标线材料的余辉亮度衰减规律，测试结果为实测18:00、20:00、22:00 3个时间点长余辉道路标线材料亮度分别为16.02 cd/m2、6.51 cd/m2、1.48 cd/m2。参照长余辉道路标线材料的实测亮度，利用Twin motion软件构建了典型道路场景，对长余辉道路标线材料发光效果进行了仿真分析。长余辉道路标线在18:00,20:00以较高的余辉亮度为驾驶员提供了较好的视线诱导效果，在22:00仍可以肉眼可识别的余辉亮度为驾驶员识别道路提供帮助。通过与实际工程应用中现场施工效果进行对照表明：仿真模型对长余辉道路标线在不同时间点余辉亮度与周边环境的模拟效果较为真实地还原了长余辉道路标线的实际应用效果，长余辉道路标线的应用可长距离显示道路线形与走向，指示道路环境，显著提升驾驶员夜间行车对道路的识别水平，有助于提高夜间行车的安全性，验证了仿真模型的有效性。该方法可为长余辉道路标线工程的施工预判及效果评价提供量化依据，降低材料大规模应用的试错成本。
Abstract：To address the challenge of evaluating the practical application effect of long-lasting phosphorescent road marking materials,this study determined the afterglow luminance decay law of the materials through indoor experiments. The test results showed that the luminance of the materials at 18:00,20:00,and 22:00 was 16.02 cd/m2,6.51 cd/m2,and 1.48 cd/m2,respectively.Referring to the measured luminance,a typical road scene was constructed using Twin motion software to conduct a simulation analysis of the luminous effect of the long-lasting phosphorescent road markings. The results showed that the markings provided good visual guidance for drivers at 18:00 and 20:00 due to their high afterglow luminance,and at 22:00,the afterglow luminance remained visible to the naked eyes,assisting drivers in road recognition. Comparison with field construction effects in practical engineering applications showed that the simulation model realistically reproduced the actual application effect of the markings by simulating the afterglow luminance at different time points and the surrounding environment. The application of long-lasting phosphorescent road markings can display road alignment and direction over long distances, indicate road environments,significantly enhance drivers' ability to recognize roads at night,and improve night-time driving safety,verifying the effectiveness of the simulation model. The method provides a quantitative basis for construction prediction and effect evaluation of long-lasting phosphorescent road marking projects,reducing the cost of trial and error for large-scale material application.
