摘要
随着交通网络的日益完善,因道路线形问题而导致的交通事故逐渐增加,尤其是在高危道路路段,线形设计不合理或设计指标应用不当极易引发交通事故.为探究高危路段线形设计对道路安全的影响,文章深入研究了高危路段的线形特征和线形设计要点,从改善弯道陡坡路段线形、线形视距控制设计、纵坡坡度和坡长设计三方面提出改进对策,以减少高危路段的安全隐患.
Abstract
With the improvement of the transportation network,traffic accidents caused by road alignment problems are gradually increasing.Especially in high-risk road sections,unreasonable alignment design or improper application of design indicators can easily lead to traffic accidents.In order to explore the influence of alignment design on road safety in high-risk road sections,this paper deeply studies the alignment characteristics and key points of alignment design in high-risk road sections,and puts forward improvement countermeasures from three aspects:improving the alignment of curved and steep slope sections,alignment sight distance control design,longitudinal slope gradient and slope length design,so as to reduce the safety hazards of high-risk road sections.
