Design on Hub-and-Spoke Network of High-Speed Railway Express Transport

With the rapid development of China's economy, consumption up- grades and the booming e-commerce express delivery industry, China high-speed rail express freight transportation came into being, and at present, more than 500 cities have opened this service. This paper based on hybrid configuration hub network, taking the high-speed rail express network and stations in northern China as an example model, a two-stage algorithm is used to divide the node level in the high-speed rail express network considering the requirements of timeliness, convenience, and benefit scale in view of its imperfect transportation network. In the first stage, the network nodes are stratified by constructing a high-speed rail express network planning index system and using the system cluster analysis method; in the second stage, based on the spatial location of each node, the K- means algorithm is used to optimize the node stratification scheme, finally obtaining the high-speed rail express hub-and-spoke transportation network layout in northern China.
