摘要
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。
To provide a suitable decision-making method for intercity rail network, based on the analysis of the adaptability connotation of intereity rail network and regional spatial structure, we set up a evaluation index system for reflecting the characteristics and relevance adaptability of the regional intercity rail network and the spatial structure. We proposed the adaptability evaluation model: the weighted grey correlation degree evaluation model based on grey correlation entropy. Using the weighted grey correlation evaluation model as the research frame, we improved the average grey correlation degree model. Applying grey entropy analysis method to determine the weight of correlation coefficient, the model can reflect the adaptability of intercity rail network and spatial structure more realistic and comprehensive. Finally, taking the rail network within Wuhan city group as an example, the rationality and effectiveness of the method is verified.
