“…Most transportation systems are organized based on nested service availability. Karimi et al [19] designed a capacitated hub median location problem with a nested hierarchical structure and used a real-world dataset from the hub location problem corresponding to the Iranian hub airport location. Li et al [20] described a hierarchical service network with a nested structure and investigated a multi-period hierarchical location problem for a transportation hub in an urban agglomeration area.…”

The rapid growth of the intercity travel demand has resulted in enormous pressure on the passenger transportation network in a megaregion area. Optimally locating hubs and allocating demands to hubs influence the effectiveness of a passenger transportation network. This study develops a hierarchical passenger hub location model considering the service availability of hierarchical hubs. A mixed integer linear programming formulation was developed to minimize the total cost of hub operation and transportation for multiple travel demands and determine the proportion of passengers that access hubs at each level. This model was implemented for the Wuhan metropolitan area in four different scenarios to illustrate the applicability of the model. Then, a sensitivity analysis was performed to assess the impact of changing key parameters on the model results. The results are compared to those of traditional models, and the findings demonstrate the importance of considering hub choice behavior in demand allocation.
