Modeling method for public transportation network with public bike sub-network based on spatial network

Abstract

The invention relates to a modeling method for a public transportation network with a public bike sub-network based on a spatial network. The method comprises the following steps: 1) counting, recording and collecting urban public transportation network data; 2) constructing a weighted directed spatial public transportation network model; 3) constructing a weighted undirected spatial walking network model; 4) constructing a weighted undirected spatial bicycle network model; 5) constructing a three-layer coupling public transportation network model of bus, walking and public bicycle networks. According to the method provided by the invention, the public transportation network model which meets the practical requirement and considers the traditional bus, public bicycle and short-distance walking is constructed, more diverse and accurate public transport tool schemes can be accordingly supplied to the passengers and the promotion for passenger satisfaction degree and running efficiency of urban road network is benefited.

Description

technical field [0001] The invention relates to the fields of network science and public transportation, in particular to a public transportation network modeling method with a public bicycle subnet based on a space network. Background technique [0002] As a low-cost, healthy and environmentally friendly way of travel, the number of public bicycle sharing systems (PBSS) is growing rapidly. So far, more than hundreds of cities around the world have established PBSS. The usage of PBSS is flexible. Generally, users can borrow bicycles from any self-service parking point and return them at any self-service parking point after use, thus becoming a supplementary method to traditional urban public transport modes (such as buses and subways). At present, the study of the performance and optimization methods of the newly established PBSS has attracted the attention of scholars and has become a research hotspot in the academic circle. For example, de Chardon et al. used the statist...

Problems solved by technology

[0005] In order to solve the problem that the existing bus network modeling method does not fully consider the impact of public bicycles and their spatial characteristics on the performance of the public bicycle network, the present invention proposes a public bicycle network construction model with high accuracy and considering the public bicycle subnetwork based on the multi-layer space network. model method
