基于问卷分析的互通立交评价方法

Evaluation Method of Interchange Based on Questionnaire Analysis

处于高度建成区的互通式立体交叉,其设计方案一般受到多个控制因素影响,当出现多个影响因素均需要考虑时,仅靠单一的定性分析难以快速、精准地在其设计过程中帮助设计人员确定控制因素的重要性以及侧重点,因此本文采用基于主观问卷调查分析的方法,以提高城市化地区高速公路互通立交设计阶段的比选优化效率及方案侧重点的科学合理性。

The design scheme of the interconnected three-dimensional intersection in the highly built-up area is generally affected by multiple control factors.When there are multiple influencing factors that need to be considered,it is difficult to help designers quickly and accurately determine the importance and focus of the control factors in the design process by relying on a single qualitative analysis.So this paper adopts the method based on subjective questionnaire survey analysis to improve the efficiency of comparison and optimization in the design stage of highway interchange in urbanized areas and the scientific rationality of the focus of the scheme.
