 要:交织区作为典型的相邻出入口,车辆要在较短的距离内完成分流、合流操作,车辆换道频繁,交通流运行复杂,形成道路交通的事故黑点及运行瓶颈,严重影响道路交通系统的运行效率。本文在收集国内外交织区大量研究文献的基础上,综述国内外道路交织区运行分析现状和通行能力研究方法,主要包括基于实测数据的回归分析法、数学理论解析法和交通仿真法。我国在交织区研究结论缺乏系统性和时效性,在交织区分类方法、通行能力计算模型和服务水平评价指标的选取应进一步简化,应与最新《公路工程技术标准》(2014)有关规定协调统一,以便更好地指导交织区的建设与管理,提高整个道路系统的运行效率和安全水平。

Abstract:  Weaving segments, as a typical area in which the entrance and exit are close to each other, merging and diverging have to be completed by vehicles within a short distance in it. There’s intense lane changes, and the traffic operation in it is complicated, thus accidents highly occurred in it and there’s also bottleneck existing,traffic efficiency of the system is seriously influenced. Based on extensive domestic and international literature on weaving segments, reviewed their weaving segments status of operational analysis and capacity research methods, mainly including regression analysis based on the measured data, the mathematical theory analytical method and traffic simulation method. Our findings in weaving segments researched is lack of systematicness and timeliness, classification method of weaving segments, capacity estimation model and indicator of level of service should be further simplified, as well as be consistent and coordinated with relating regulations of the newest Highway Engineering Technique Standards”(2014, to better guide weaving segments construction and management, and improve the operation efficiency and safety level of the entire road system.
