摘要
鉴于国道公路隧道与互通立交间距过小的复杂影响性以及缺少相关的成熟分析方法,本研究在对项目背景、预测交通量等基础资料理解研究的基础上,参考国内外现有安全性评价手册,利用国内外成熟的道路安全研究成果,并借鉴现有互通立交、隧道设计和运营阶段取得的经验、教训,综合应用设计指标核查、换道过程分析、交通环境仿真等多种分析评价手段对项目路段进行分析,最后探讨本项目隧道与互通间距设置方案的合理性,并给出相关安全保障措施.
Abstract
In view of the complex impact of the small distance between national highway tunnels and interchanges,as well as the lack of relevant mature analysis methods,this study,based on the understanding and research of basic information such as project background and predicted traffic volume,draws on existing safety evaluation manuals at home and abroad,utilizes mature road safety research results at home and abroad,and draws on the experience and lessons learned from the design and operation stages of existing interchanges,tunnels,etc.By comprehensively applying various analysis and evaluation methods such as design indicator verification,lane change process analysis,and traffic environment simulation,the project section is analyzed.Finally,the rationality of the tunnel and interchange spacing setting plan for this project is discussed,and relevant safety measures are provided.
