城市立体交叉方案的集对分析模型研究

SPA Model for the Assessment of Urban Three-dimensional Crossroad Design Plan

基于集对分析理论，提出了城市立体交叉设计方案的评价模型．运用层次分析法建立了各评价指标的层次结构，确定其权重，消除了专家评定确定权重时的人为因素干扰，提高了设计方案评价的可信度，为城市立体交叉设计方案的选优提供了简单、实用的评价方法。

The set pair analysis(SPA) model for urban three-dimensional crossroad is discussed.And with the analytic hierarchy process(APH),this paper proposes the APH index hierarchy and the index coefficients,which can reduce the interference created by experts' coefficient and improve the reliability of designing scheme assessment,thus providing a simple and effective appraisal method for optimization of urban three-dimensional crossroad design plans.
