城市道路交叉口进口道车道功能置换适应性研究

Adaptability of Lane Function Replacement at Approach of Urban Intersection

城市道路路段车辆交织行为对道路路段通行能力有较大影响,在一定的道路交通条件下,进行车道功能置换设计可减少车辆交织行为,有助于提高道路通行能力。通过借鉴国内外对快速路交织区研究的成果,在分析城市道路路段车辆交织行为的基础上,运用微观仿真软件Vissim对各种道路交通条件下车辆交织行为进行仿真分析,以路段平均行程车速为评价指标,得到了车道功能置换设计方法的适用条件。

Vehicles＇ weaving behaviors have great influence on capacity of urban road sections. In some cases, by reducing weaving behaviors, lane function replacement can greatly improve vehicle＇s running condition and increase road sections＇ capacity. Based on the research achievements about expressway＇s weaving areas home and abroad, and using micro-simulation tool VISSIM, this research analyzed vehicles＇ weaving behaviors on urban road and obtained the adaptability of lane function replacement at approach of urban road intersection.
