互通式立体交叉比选方案安全性评价研究

Study on Safety Audit of Alternative Schemes for Interchange

互通式立体交叉比选方案安全性评价是公路项目安全性评价工作中的重要组成部分,是通过定性及定量方法比较各方案的安全性,推荐最优方案。为实现客观科学的安全评价,文章在大量实践基础上提出了互通式立体交叉比选方案安全评价指标体系,构建出模糊综合安全评价模型,并通过实际案例验证了指标体系及评价模型的有效性。研究成果能为互通式立体交叉比选方案安全评价提供方法指导,并将支撑《公路项目安全性评价规程》(T/CECS G: E10-2021)、贵州省公路项目安全性评价指南(项目编号:2020-141-022)相关条文。

Safety audit of alternative schemes for interchange is an important part of highway safety audit. In order to recommend an optimum interchange scheme with the best traffic safety performance, alternative schemes are compared qualitatively and quantitatively for highway safety audit. To obtain objective evaluation results for safety audit, a fuzzy comprehensive safety evaluation model with indicators is proposed in the paper, based on a lot of practice. Design cases are introduced and proved the model effectiveness. The model will be a safety audit method cited by Technical Specifications for Highway Safety Audit (T/CECS G: E10-2021) and Guizhou Provincial highway Safety Audit Guidelines (2020-141-022).
