Research on Alignment Design of High-risk Road Section
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.
