为城际轨道网布局的适应性提供适用的决策方法,在分析城际轨道交通网络与区域空间结构适应性内涵的基础上,建立了既能反映区域城际轨道交通网络和区域空间结构主要特征,又能反映二者相关联的适应性评价指标体系。提出城市群城际轨道网布局的适应性评价模型——基于灰色关联熵的加权灰色关联度评价模型。该模型以加权灰色关联评价模型作为研究框架,对平均灰色关联度模型进行改进,应用灰熵分析方法确定关联系数的权重,更真实全面地反映了城际轨道网布局与区域空间结构的适应性情况。以武汉都市圈城际轨道交通线网规划为例,验证该方法的合理性和有效可行性。
Based on the analysis of the connotation of intercity rail transit network and the adaptability of regional space structure, this paper establishes a method that can not only reflect the main features of regional inter-city rail transit network and regional spatial structure , But also reflect the two indicators of adaptive evaluation system. The adaptability evaluation model of intercity rail network layout for urban agglomeration is proposed - weighted gray relational assessment model based on gray relation entropy. The model uses the weighted gray relational evaluation model as the research framework, improves the average gray relational degree model, and uses the gray entropy analysis method to determine the weight of the correlation coefficient, which reflects the adaptability of inter-city rail network layout and regional spatial structure more truthfully and comprehensively Happening. Taking the planning of intercity rail transit network in Wuhan metropolitan area as an example, the rationality, feasibility and feasibility of this method are verified.
