Method for screening ground bus lines to be adjusted at initial stage of rail transit network formation

Abstract

The invention discloses a method for screening the ground bus lines to be adjusted at the initial stage of the rail transit network formation. The method comprises the following steps of 1) analyzingthe width of a rail transit corridor belt; 2) selecting a line characteristic index, performing the dimension reduction processing by adopting a principal component analysis method, and extracting a principal component for representing the line characteristic; and 3) clustering the line indexes within the influence range of the rail transit by using a hierarchical clustering analysis method, analyzing the statistical indexes of the characteristics of each cluster, and taking different adjustment measures. The method is based on the qualitative analysis, the classification characteristics of the ground common lines are defined by quantitative analysis, the coordination state of the ground bus and the rail transit can be comprehensively analyzed from the aspects of line geometry, transportation capacity, passenger flow requirements, spatial relationships, competitive relationships and the like, reference is provided for further formulating a detailed line adjustment scheme, the public transport resource integration and reasonable distribution are facilitated, the mutual competition between the two public transport modes is relieved, and the joining and cooperation are enhanced.

Description

technical field [0001] The invention belongs to the technical field of optimization of public transportation lines, and in particular relates to a method for screening public transportation lines on the ground at the initial stage of rail transit network formation. Background technique [0002] When cities in China select the ground bus lines to be adjusted on the corridors in practice, the main basis for discrimination is the number or distance of collinear stations between rail transit lines and ground bus lines. The index values ​​are obtained through empirical methods, and each city has Big difference. When considering the adjustment of ground bus lines, existing studies generally only consider the spatial relationship between ground bus lines and a single rail line, and the applicability to cities in the initial stage of rail network formation needs to be enhanced. In the initial stage of networkization, rail transit usually forms a radial network centered on the core ...

AI Technical Summary

Problems solved by technology

In the process of formulating the adjustment strategy, the principle of avoiding parallel line competition is generally the principle, and the line is canceled or transferred to the secondary passenger flow corridor, and the transfer cooperation relationship between rail transit and ground bus is not fully considered.
