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。
In order to improve the effectiveness of inter-city rail network layout planning, the concept of inter-city rail transit location and inter-city rail network evolution is proposed, and the concept of high-speed passenger transportation area line is put forward and a multi-level inter-city rail transit network optimization model. Optimization model will be divided into inter-city rail network backbone network and the initial line network. The backbone network optimization model is the minimum spanning tree model with the reciprocal of the economic strength as the weight. The initial network optimization model is a multi-objective function model that maximizes the network economic connection and the network connectivity. The total rail transit line The minimum length. The optimization model provides a new method for inter-city rail network planning. Finally, taking the intercity rail transit network of Wuhan City Cluster as an example, the rationality and feasibility of the layout method are verified.
