高速公路交通事故调查与安全设施优化分析

Highway traffic accident investigation and safety facility optimization analysis

结合改扩建高速公路交通安全设施设置实践,结合交通事故调查结果分析提出优化方案。选取调查路段,收集近一年的交通事故记录,分析交通安全设施设置存在的问题。从标志标线、护栏、诱导标志等方面对交通安全设施进行分析和优化,最终得出一套科学合理的设计方案。

Combined with the practice of setting up traffic safety facilities for the reconstruction and expansion of expressways,and combining with the analysis of traffic accident investigation results,an optimization plan is proposed.Select survey road sections,collect traffic accident records for the past year,and analyze the problems existing in the installation of traffic safety facilities.Analyze and optimize the traffic safety facilities from the signs and markings,guardrails,and guidance signs,and finally arrive at a scientific and reasonable design plan.
