Composite bus subway network model construction method

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...

Problems solved by technology

If only the bus station and the subway station exist at the same time as the connection point of the bus and the subway, ignoring those who walk a distance to transfer to each other, this will invisibly weaken the coverage of a subway station, which is different from the actual situation.
