基于模体和复杂网络的成都市交通旅客出行研究OA

A travel model(TM)was designed to extract and transform the passenger travel sequence,and a travel model based on regional railway and air travel passengers was constructed.The empirical analysis was conducted based on the passenger travel data of a large city in Sichuan Province.The passenger travel model consisting of two to four nodes can represent the vast majority of passenger travel modes.The main travel models are one-way single trip and round-trip trip between two nodes.As time goes by,the attractiveness of railway travel to users gradually increases,while air travel gradually decreases.The characteristics of regional railway travel network(RRTN)and air passenger travel network(RATN)were studied.Both travel networks are heterogeneous.Large nodes in the network tend to connect small nodes.The network clustering coefficient is large,and different stations in the network are closely connected.The structure of the railway passenger travel network in this region is stable and most of them are concentrated in the southeast of China.The air travel network is gradually developed and has a higher dispersion.The results of network efficiency research show that the connectivity of regional passenger travel networks is general,mostly concentrated in specific regions.
