【摘要】 为提高城际轨道网络布局规划的有效性,通过分析城际轨道交通区位及城际轨道网络自身演化特征,提出了高速客运交通区位线的概念,并构建了多层次的城际轨道交通网络优化模型。优化模型将城际轨道网络分为骨干线网和初步线网。骨干线网优化模型是以经济联系强度的倒数为权重的最小生成树模型;初步线网优化模型是多目标函数模型,它使得网络经济联系强度最大、网络的连通度最高、总的轨道交通线路长度最小。优化模型为城际轨道网络规划提供了新的方法。最后,以武汉城市群城际轨道交通网络为例,验算了该布局方法的合理性及可行性。更多还原

【Abstract】 In order to improve the effectiveness of intercity rail transit network layout planning,by analyzing intercity rail traffic location and the network evolution characteristics,the concept of high speed passenger traffic location line is put forward,and the multi-level intercity rail transit network optimization model is built. The model divided the intercity rail transit network into the backbone network and the preliminary network. The backbone network optimization model is the minimum spanning tree model which uses the reciprocal of economical relation intensity as its weight. The preliminary network model is a multi-objective function model whose object is to maximize the economical relation intensity,connectivity of the network,and minimize the total rail transit lines’ length. The optimization model provided a new method for intercity rail transit network planning. Finally, taking the Wuhan agglomeration intercity rail transit network as an example,the rationality and effectiveness of the network layout method is verified.更多还原
