Problems solved by technology

First of all, bus information generally includes two parts: bus stops (which can be regarded as nodes in a complex network) and bus lines (which can be regarded as correlation features between nodes in a complex network), which are collected manually on network maps and web pages. time cost is very high
Secondly, if the data formats in different regions are not unified, it will have a negative impact on the results of the analysis
Therefore, the unification of data formats and standards must be fully considered in data acquisition, but this is difficult for data acquirers
[0004] (2) How to use web network resources to quickly obtain bus information of multiple cities, the analysis of a single city often cannot meet the actual needs

Embodiment Construction

[0058] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0059] Those skilled in the art can understand that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which this invention belongs.

[0060] The present invention proposes a web-based method for automatically generating complex urban public transport networks, comprising the following steps:

[0061] Step 1) See attached figure 1 , first obtain the bus station information in the research area through crawler technology.

[0062] Step 1.1) Calculate the minimum circumscribed rectangle of the research area defined by the user on the map.

[0063] Step 1.2) See attached figure 2 , divide the minimum circumscribed rectangle into grids of equal size to form a grid dataset.

[0064] Step 1.3) Traverse the network data...

Abstract

The invention discloses a web-based city bus complex network automatic generation method. The method comprises the following steps: firstly, acquiring bus stop and bus route information in a researcharea through a crawler technology; secondly, based on principles such as distance constraint, deleting redundant bus stations, and establishing a bus connection relationship between the bus stations;and finally, according to a complex network theory, establishing a bus complex network and carrying out visual analysis. According to the method, the complex bus network in the city can be rapidly obtained, and a scientific basis is provided for city bus travel optimization.

Description

technical field [0001] The invention relates to the technical field of urban planning and urban traffic systems, in particular to a web-based automatic generation method for urban public transport complex networks. Background technique [0002] At present, big data technology has been widely used in urban planning and urban traffic analysis, among which the research on public transportation network has become a hot topic among them. Due to the strong network characteristics of public transportation, the complex network has become an important technical means in the research. However, there are still the following problems: [0003] (1) There are still some difficulties in data acquisition. First of all, bus information generally includes two parts: bus stops (which can be regarded as nodes in a complex network) and bus lines (which can be regarded as correlation features between nodes in a complex network), which are collected manually on network maps and web pages. The t...
