摘　　要：选取相邻路段车速差ΔV、车速降低系数SRC和速度离差作为鉴别双车道公路危险路段的三个评价指标,从道路工程措施和交通安全设施两方面对事故多发路段进行安全改善对策研究。以内蒙古S203公路为例,利用评价指标进行危险路段判析,针对K465+900急弯陡坡危险路段,通过线形改造以及设置交通标志标线、减速设施、避险车道和防护设施等一系列工程改造措施,进行安全改善综合方案设计。Speed difference of adjacent sectionsAV.speed reduction coefficient SRC and speed dicrete degree are chosen by the author as two--lane highway dangerous section evaluation indexes. And the countermeasures with road alignment and safety facilities to improve road traffic safety are put forward. Based on the K463-K469 sections of S203 in Inner Mongolia, evaluation indexes are used to analyze the dangerous section. The combination design of the dangerous road section by using the traffic safety equipments is in- troduced and it is referential to the related projects.
