基于AHP-熵权法比较的分期实施互通立交选型研究

Research on Type Selection of Interchange Implemented in Stages Based on the Comparison of AHP-entropy Weight Method

不同技术人员对存在远期规划的互通式立体交叉选型方案的选择存在一定差异,文章提出了一种基于AHP-熵权法的互通式立交选型方法。在现有的工程规模选择标准的基础上,增加了社会成本比选,然后调整评定数据指标权重,计算得到评定结果,并以某互通立交为例,探究该方法在互通立交选型评定中的适用性。结果表明,该互通符合现状方案及远期规划需求。

There are some differences in the type selection schemes of interchange with long-term planning among different technicians.A kind of type selection method of interchange based on AHP-entropy weight method is put forward.On the basis of the existing project scale selection criteria,the social cost comparison and selection is added,and then the weight of the evaluation data index is adjusted to calculate the evaluation results.Taking an interchange as the example,the applicability of this method in the evaluation of interchange type selection is explored.The results show that,the interchange is in line with the current scheme and the requirement of long-term planning.
