眩光所造成的驾驶员判断与操作失误是诱发夜间交通事故的一个重要原因。根据城市道路眩光对驾驶员的影响,以城市道路中央隔离栏杆为载体,在其基础上进行防眩设施的设计与改善,同时增加韵律型波形图案,提高隔离栏杆的美感,提升行车安全性、舒适性。研究结果表明:在城市道路中央隔离栏杆上安装防眩设施后,中央隔离栏杆的遮光面积提高了1.7倍,并且经济分析表明,投资成本相比改善前提高了25%,但是相比常用的防眩柱投资成本降低了20%,因此,本方案在遮光效果和经济性方面都可行。
Glare caused by the driver’s judgment and operational errors is a major cause of night-time traffic accidents. According to the influence of the urban road glare on the driver, the balustrade of the urban central road is used as a carrier, and the design and improvement of the anti-glare facility are carried out on the basis of the urban road glare. At the same time, the rhythmic waveform pattern is increased to improve the aesthetics of the isolation railing and enhance traffic safety. Comfort. The results of the study show that the shading area of the central segregation railings has increased by 1.7 times when glare-proofing facilities are installed on the central railings of urban roads, and the economic analysis shows that the investment cost is increased by 25% compared with that before the improvement, Glare column investment costs reduced by 20%, therefore, this program is shading effect and economy are feasible.
