公路互通式立交方案比选的AHP方法

Method of AHP for Choosing the Best Plan of Highway Interchange

公路互通式立体交叉存在多个设计方案,如何进行客观的方案比较是十分重要的。本文针对公路互通式立交方案比选的问题,提出了立交方案比选的一种新方法—层次分析法(AHP方法),对AHP方法的应用步骤进行了详细地说明,并构建了简单、方便的层次结构分析模型,结合实例详细介绍这种方法的应用。

There are many plans in designing highway interchange.It s very important to choose the best plan objectively.In order to choose the best plan of highway interchange,a new method Analytic Hierarchy Process(AHP) is given,and application procedures are introduced in detail.The simple and practical hierarchy structure model is built and how to use the method through an example is also introduced in this paper.
