摘 要:针对越江越海隧道入口处事故多发问题,提出了一种基于自发光标线的改善策略。采用实车试验研究不同光环境下自发光标线的视认性能,以此验证自发光标线代替普通标线的可行性,并探究不同亮度与颜色之间的差异;构建越江越海隧道入口段三维场景进行驾驶模拟试验,分析驾驶人在不同场景下的驾驶行为与主观感受,以此验证自发光标线设置于越江越海隧道入口段的应用效果。试验结果表明:在环境照度大于50000 lx时,与280、2500 cd/m^(2)相比,亮度为1500 cd/m^(2)的自发光标线视认性能最佳,其视认距离均值与普通标线接近,最高可达89 m;与黄色和白色相比,橙色自发光标线在视认性与舒适度方面均表现更好。在环境照度小于100 lx时,不同色温及亮度的自发光标线相较普通标线均可提升20 m以上的视认距离。此外,亮度对舒适度影响显著,其中280 cd/m^(2)表现最佳,而色温对舒适度影响不显著。相较于普通标线场景,自发光标线场景中车辆的车道保持性能更佳,行驶车速降低5~20 km/h。通过自发光标线的提前警示,驾驶人刹车踩踏频率、最大刹车力度与持续距离均有所减少,驾驶人主观感受上其紧张感与操作难度有所降低,自发光标线的应用对越江越海隧道入口处安全改善具有一定的效果。研究结果可为自发光标线或类似地面发光设施的亮度设置、应用方案设计等提供参考。Aiming at the problem of frequent accidents at the entrance of cross-river and cross-sea tunnel,an improvement strategy was proposed based on self-luminous road markings.The visual recognition performance of self-luminous road markings in different light environments was studied by real vehicle experiments,so as to verify the feasibility of replacing the ordinary road markings with self-luminous road markings,and to study the difference caused by different brightness and color.A three-dimensional scene of the entrance section of the cross-river and cross-sea tunnel was constructed to conduct driving simulation experiments,and the driving behavior and subjective feelings of drivers in different scenes were analyzed,so as to verify the application effect of setting the self-luminous road markings at the entrance section of the crossriver and cross-sea tunnel.The results show that when the ambient illuminance is greater than 50000 lx,compared with 280 and 2500 cd/m^(2),the self-luminous road markings with a brightness of 1500 cd/m^(2)have the best visual recognition performance,and its average visual recognition distance is close to that of ordinary road markings,up to 89 m.Compared to yellow and white,orange self-luminous road markings are better in terms of visibility and comfort.When the ambient illuminance is less than 1oo lx,the self-luminous road markings of different colors and brightness can increase the visual recognition distance by more than 20 m compared with ordinary road markings.In addition,brightness has a significant effect on comfort,brightness of 280 cd/m^(2)performs best,color has no significant effect on comfort.Compared with the ordinary road markings scene,the lane keeping performance of the vehicle in the self-luminous road markings scene is better,and the driving speed is reduced by 5 to 20 km/h.Through the advance warning of self-luminous road markings,the driver's braking frequency,maximum braking force and continuous distance are reduced,and the driver's subjective feeling of tension and
