Results of objective weight calculation.

Traffic markings have inadequate nighttime visibility for safe driving. To address this and reduce nighttime accidents, we researched and developed long afterglow luminescent coatings, including performance and simulation studies. By varying the dosage of luminescent powder, glass powder, and titanium dioxide, nine groups of coatings were fabricated via blending. Their luminescence and chromaticity properties were investigated. Using CW-VIKOR comprehensive evaluation, the optimal formulation was selected. This optimal coating was further analyzed using Twinmotion and DIALux simulations, assessing marking visibility and tunnel illumination effects with the coatings.Results revealed that increased luminescent powder dosage enhanced luminescence performance. The optimal formulation (30% luminescent powder, 8% glass powder, 4% titanium dioxide) achieved the best luminescence performance and colorimetric characteristics, sustaining light emission for 9 hours with good road performance. Twinmotion simulations demonstrated better nighttime visibility at different brightness levels. DIALux simulations showed a 22.3% increase in average tunnel brightness after coating deployment, significantly improving lighting effects.

道路交通标线夜间可视性不足，难以保障安全驾驶。为解决该问题并降低夜间交通事故发生率，本研究研发了长余辉发光涂料（long afterglow luminescent coatings），并开展了性能与仿真相关研究。通过改变发光粉（luminescent powder）、玻璃粉与二氧化钛（titanium dioxide）的掺量，采用共混法制备了9组涂料试样，对其发光性能与色度特性展开测试分析。采用CW-VIKOR综合评价法筛选得到最优配方。针对该最优涂料，进一步采用Twinmotion与DIALux软件开展仿真分析，评估该涂料应用于标线后的可视性与隧道照明效果。研究结果表明，提升发光粉掺量可有效改善涂料的发光性能。最优配方（发光粉掺量30%、玻璃粉掺量8%、二氧化钛掺量4%）兼具最优的发光性能与色度特性，可持续发光9小时，且路面适配性能优异。Twinmotion仿真结果显示，该标线在不同亮度等级下均具备更优的夜间可视性。DIALux仿真结果表明，涂料应用后隧道平均亮度提升22.3%，照明效果得到显著改善。
