Embodiment Construction

[0034] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0035] Such as figure 2 As shown, the method includes the following steps:

[0036] Step 1), establish a bus and subway double-layer network.

[0037] In order to show the actual effect of the present invention more intuitively, the present invention is applied to the bus and subway network in Nanjing urban area. Among them, the bus and subway data are the bus and subway data in Nanjing urban area.

[0038] In step 2), the subway stations in the subway network that are connected to the bus network are classified as A-type stations, and the rest are classified as B-type stations, that is, those subway stations that do not have inter-layer connections.

[0039] This step mainly deals with how the subway stations are mapped to the bus network in order to construct a composite network. If a bus station and a subway station appear at the same time ...

Abstract

The invention discloses a composite bus subway network model construction method. Through comprehensively comparing an average clustering coefficient and an average path length of a composite network under non-weighted conditions and a weighted average path length of the network under weighted conditions, an optimal model parameter d can be acquired. The method comprises steps that firstly, a bus subway dual-layer network is constructed according to a dual-layer network model, connection between nodes in the network and connection between network layers of the dual-layer network are both realized. When a subway network is composed to a bus network, node mapping including node fusion and establishment and connection edge re-connection are both processed, and connection edge re-connection is influenced by the model parameter d. Parameters of the composite network under different d value conditions are compared, the optimal value of the d can be determined; buses and subways can be reasonably connected together through the optimal model parameter d, and passenger travel efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of public transportation networks, in particular to a method for constructing a bus and subway composite network model. Background technique [0002] Urban public transportation is an important part of urban transportation. With the continuous advancement of urbanization and the continuous increase of population, the contradiction between the development of urban public transportation and the increasing transportation needs of urban residents has become increasingly prominent. These transportation problems are also serious. It affects the economic construction of the city and the operating efficiency of the city. In recent years, my country has vigorously promoted the priority development strategy of public transportation, and gradually developed into a comprehensive transportation system with ground transportation as the mainstay and rail transportation as the backbone. Therefore, the connection between bu...
