高速公路互通立交安全风险分析及改善

Safety Risk Analysis and Improvement of Expressway Interchange

高速公路互通立交路段的事故数量和严重程度往往高于一般路段。现对高速公路互通立交路段的常见风险进行分析,归纳出车流紊乱、标志标线设置不当、视距不足、车道平衡、短间距交叉、夜间行车等安全风险问题,并提出基于小规模土建的针对性改善方案。

With the development of economy,China's expressway mileage is increasing.On the other hand,people pay more and more attention to traffic safety.The number and severity of accidents in expressway interchange sections are usually higher than those in general sections.This paper summarizes and analyzes the common risks of expressway interchange sections,and puts forward some safety risks,such as traffic flow disorder,improper setting of signs and lines,insufficient visual distance,lane balance,short spacing intersection,night driving,and proposes targeted improvement schemes based on small-scale civil construction.
