Hierarchical Model for Regional Integrated Passenger Hub Layout

To improve the rationality of integrated passenger hub layout, the relationship between integrated passenger hub classification and passenger transport demand was analyzed, then a hierarchical model with capacity constraints was proposed. Next, immune clonal algorithm was applied to solve the problem. Finally, a numerical example was given to validate the effectiveness of the model and algorithm. The results show that the model is superior to P-median model. In addition, it is reflected that changes of demand have a great impact on hub layout, which provides decision references for hub planning department.
