快速路系统适应性评价是多目标综合评价问题。首先对快速路适应性的相关概念进行界定,建立了包括路网的布局指标、交通运行的质量指标、社会影响指标、环境影响指标的4类影响因素的2级评价指标体系,并给出部分各指标的具体计算方法或评定依据;其次研究了系统评价指标隶属度关系,并进行评价指标分级及权重值计算;提出了适合快速路系统适应性评价的模糊综合评价模型。最后以具体案例进行了分析计算,文中提出的模糊综合评价方法可应用于快速路系统适应性评价。
The adaptability evaluation of expressway system is a multi-objective comprehensive evaluation problem. First of all, it defines the related concepts of expressway adaptability, and establishes a two-level evaluation index system including four kinds of influencing factors: layout index of road network, traffic quality indicators, social impact indicators and environmental impact indicators, The specific calculation method or evaluation basis of each index; Secondly, the relationship between the membership of system evaluation index and the evaluation index grading and weight value calculation are studied; and the fuzzy comprehensive evaluation model suitable for adaptive evaluation of expressway system is proposed. Finally, the concrete case is analyzed and calculated. The fuzzy comprehensive evaluation method proposed in this paper can be applied to the adaptive evaluation of expressway system.
