城际轨道交通线网规划综合评价研究

结合都市圈城际轨道交通线网规划评价决策的特点,探讨城际轨道交通线网评价指标体系和线网规划方案评价方法的优选,提出适用于都市圈城际轨道交通线网规划评价的“层次分析法-熵-灰色关联”组合评价模型。该模型将层次分析法、信息熵理论和灰色关联决策方法有机结合起来。以长江三角洲都市圈城际轨道交通线网规划为例,编制相关软件进行组合评价,验证该方法的合理性和有效可行性。

Study on Synthetic Evaluation of Inter-city Rail Transit Planning

Based on analyzing the characteristics of evaluation and decision of inter-city rail transit planning, this paper establishes a comprehensive evaluation index system of inter-city rail transit line network planning, and discusses the choice of the better evaluation methods. Then this paper puts forward an applicable evaluation model that combines the AHP, information entropy theory and grey correlation degree model as an organic whole. At last, taking the planning of the inter-city rail transit network in the Yangtze River Delta as an example, this paper illustrates the combined evaluation model by program calculation. Its rationality and feasibility are verified.
