摘要
为了给道路交通标线的设计与应用提供参考,提高道路安全性,减少交通事故发生概率,探索不同条件下预成形标线和传统热熔标线的视认性能,进行交通标线视认性能的驾驶试验研究。设计不同光照强度、天气等条件下的多种实验场景,采用方差分析研究各个因素对标线视认距离影响的显著性及其交互作用。结果表明,在白天亮度较高条件下,白色热熔标线和黄色预成形标线对于视认距离无显著影响;在晚上亮度较低的条件下,对比热熔标线,预成形标线在视认距离上有很大提升。在晴天、雨天条件下,预成形标线对比热熔标线在视认距离上都有很大提升,其中白色预成形标线在雨天条件下的效果最好。试验结果显示,不同因素影响下,预成形标线的视认性能要明显强于传统热熔标线。
In order to provide reference for the design and application of road traffic markings,improve road safety and reduce the probability of traffic accidents,the visual recognition performance of pre-formed markings and traditional hot-melt markings under different conditions was explored,and a driving test study on the visual recognition performance of traffic markings was carried out.A variety of experimental scenarios under different light intensities,weather and other conditions were designed,and variance analysis was used to study the significance and interaction of each factor on the visual recognition distance of the marking line.The results show that under the condition of high brightness in the daytime,the white hot-melt marking line and the yellow pre-formed marking have no significant effect on the visual recognition distance.While under the condition of low brightness at night,compared with the hot-melt marking line,the visual recognition distance of the pre-formed marking line is greatly improved.In both sunny and rainy weather conditions,the visual recognition distance of pre-formed markings compared with hot-melt markings has been greatly improved.Among them,white pre-formed markings have the best effect under rainy conditions.The test results show that under the influence of different factors,the visual recognition performance of pre-formed marking lines is significantly stronger than that of traditional hot-melt marking lines.
