Research on a Freight Modal Split Model Based on Transportation Distance

摘要

How to reasonably determine the freight modal split model has always been a hot topic of research at home and abroad. In recent years, while a lot of researches have been made both at home and abroad on the passenger transport modal split mode, researches on the freight modal split model are scarce. Due to the sharp increase of freight demands as well as the theoretical need of the planning for the comprehensive transportation system, the freight modal split model have attracted the attention of experts and scholars. In this study, the expression of the functional relation between various freight volumes and transportation distance is constructed through analyzing a large number of aggregate data regarding different freight volumes and transportation distances among Chinese cities, and the change law of freight modal split with different transportation distance in the comprehensive transportation system is analyzed, so as to provide a reference and basis for the rational allocation of transportation resources and the optimization of transportation structure.
