基于节点重要度法的高速公路与城市道路衔接线位置研究

The Position of Connected-way for Highway and Urban Road Based on Node Importance Analysis Method

研究了高速公路与城市道路衔接规划中衔接线与城市道路衔接位置的选取问题;分析了基于互通式立交数量确定衔接线数量的方法,设计了节点重要度法用以优化衔接线位置,包括节点及其评价指标的选择、聚类计算及分析等;最后,将节点重要度法应用于潍坊市与济青高速公路衔接线布局规划,通过计算得到了可行结果。

The optimizing for location of connected-way for urban road was studied on the problem of layout planning for connected-way of highway and urban road, The method for connected-way number based on the interchange number was analyzed,and then the node importance analysis method was designed for the optimizing of location for connected way,which includes the selection of node and its indexes, cluster calculation and analysis and so on. Finally, the method proposed was applied to the layout planning for connected-way of Jinan-Qingdao highway and Weifang urban road. The result approves the feasibility of the method.
