分析了城际轨道交通节点重要度和经济引力指标,探讨了城际轨道交通线网主骨架确定方法。基于规划区域内客流集散点分析,考虑节点重要度的影响因素,建立了重要度指标体系,采用层次分析法(AHP)计算了各节点的重要度。引入经济引力指数,测算了城镇群区域各中心城市间的经济引力。以节点的重要度和经济引力为目标,提出了城际轨道主骨架布局双重优化模型。采用改进PSO算法,确定了主骨架布局初选方案,利用城际客运走廊进行了修正,最终确定了城际轨道交通线网的主骨架,并以宁夏沿黄经济区城际轨道交通线网规划进行了实证。
The importance of inter-city rail transit nodes and the index of economic gravity are analyzed, and the method to determine the main skeleton of inter-city rail transit network is discussed. Based on the analysis of passenger flow distribution points in the planning area and the influential factors of node importance, the importance index system was established and the importance of each node was calculated by Analytic Hierarchy Process (AHP). The economic gravitation index was introduced to calculate the economic attraction among the central cities in the urban agglomeration. With the importance of nodes and economic attraction as the goal, a double optimization model of the main skeleton layout of inter-city railways is proposed. The improved PSO algorithm was used to determine the primary skeleton layout of the primary scheme and the inter-city passenger corridor was amended to finalize the main framework of the inter-city rail transit network. The inter-city rail transit network planning of the economic zone along the Yellow River in Ningxia An empirical.
