摘要
平面交叉口是公路交通流的一个重要交汇点,其安全性至关重要,需要对交叉口进行深入的安全性分析和评估。以某公路为主要研究对象,结合网络数据对该公路展开安全养护评估分析,明确安全养护评估结果,分析当前评价方法存在的问题,提出多源数据融合与全过程评价的闭环体系,以此为公路平面交叉口提供科学、系统的养护管理支持。研究发现,现有的道路平面交通安全养护评价体系缺乏对道路线形安全性、大货车混行比例和护栏防撞指数合格率等的评价标准。
Grade intersections are important junctions for highway trafficflow,and their safety is of vital importance,requiring in-depth safety analysis and evaluation.Taking a certain highway as the main research object,this study carries out safety maintenance evaluation and analysis by integrating network data,clarifies the evaluation results,analyzes the problems in current evaluation methods,and proposes a closed-loop system of multi-source data fusion and whole-process evaluation to provide scientific and systematic maintenance management support for highway grade intersections.The studyfinds that the existing safety maintenance evaluation system for highway grade intersections lacks evaluation criteria for road alignment safety,mixed traffic proportion of large trucks,and qualified rate of guardrail crashworthiness index.
