Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings.

[0039] see figure 1 , the present invention mainly is divided into four parts:

[0040] The first step: selection of lines, collection of working condition data and calculation of eigenvalues;

[0041] (1) Select N bus lines in combination with line station strength and coverage area. Site strength refers to the number of bus lines passing through the site, and its size indicates the importance of the site, including comprehensive factors such as human flow, traffic flow, and commercial status. Combined with the overall station distribution and station strength distribution of the city, select N1 lines with high station strength, N2 lines with average station strength, and N3 lines with low station strength. Its N lines should basically cover most areas of the city and have certain representativeness.

[0042] (2) Collect and preprocess the operating condition data...

Abstract

The invention discloses a city bus working condition construction method based on multi-line coupling. The method is characterized by combining line site intensity and a covering area, selecting N bus lines; through data acquisition and pretreatment, carrying out cluster analysis on each line data and providing a line coupling weighting factor Wi; according to the weighting factor, determining each line time distribution ratio; combining a working condition length (a total working condition length Tz is in a certain interval range) so as to determine minimum time Tmin of the line ratio; calculating a characteristic value of each clustered working condition; according to each kind ratio after clustering, constructing two kinds of working condition trapezoids corresponding to each line; and according to the characteristic value, carrying out curve fitting on each working condition trapezoid for four times, successively combining and forming a final line-coupled city bus working condition. Precision of constructed city bus working condition is increased.

Description

technical field [0001] The invention belongs to the field of construction of urban public transport operating conditions, and in particular relates to a construction method of urban public transport operating conditions based on multi-line coupling. Background technique [0002] The construction of urban bus operating conditions has always been a complex issue, including line selection, data collection, data processing, line coupling, and the construction of urban bus operating conditions. Due to the large number of urban bus lines, it is difficult to collect them all, and the line strength and collection times of each line are different, and there are few coupling methods for the working conditions of each line. Therefore, the construction method of the urban working conditions of buses is not yet mature. [0003] In the selection process of urban lines, on the one hand, the coverage area of ​​the line, and on the other hand, the station strength of the line also needs to b...
