【摘要】：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。
[Abstract]:The error of driver's judgment and operation caused by glare is an important reason to induce traffic accident at night. According to the influence of urban road glare on drivers, the design and improvement of anti-dizziness facilities are carried out on the basis of the central isolated railings of urban roads. Meanwhile, the rhythmic waveform pattern is added to enhance the aesthetic sense of the isolated railings. Improve driving safety, comfort. The results show that after installing anti-glare facilities on the central isolation railings of urban roads, the shading area of the central isolation railings increases by 1.7 times, and the economic analysis shows that, The investment cost is increased by 25% compared with that before improvement, but the investment cost is reduced by 20% compared with the usual anti-dazzling column. Therefore, this scheme is feasible in the aspects of shading effect and economy.
