Problems solved by technology

At present, most of the research on the construction of urban public transport conditions at home and abroad is the construction of a single line or a simple combination of multiple lines. The operating conditions of several lines are spliced ​​into urban bus operating conditions, which is poor in regional representation and cannot truly reflect the actual operating status of urban or regional buses

Embodiment

[0026] The statistical data collected in this paper are the actual operation data and detailed information of the bus stops in a certain city. The method of representative route selection and database establishment is proposed, and the data is classified and sorted by using short-distance division method, principal component analysis and cluster analysis method. Establish various representative working conditions and determine the time ratio; determine the station classification threshold and classify all bus stops in the city or region; determine the weight factors of various working conditions and select representatives according to the weight factors Working condition data to complete the construction of urban or regional road cycle working conditions.

[0027] see figure 1 , the detailed steps are described below:

[0028] (1) Select n representative bus lines to collect data on vehicle roads; urban bus cycle data collection requires sufficient coverage, so the following ...

Abstract

The invention discloses a method for constructing urban bus working conditions, fully collects and counts urban bus road operation data and site information, proposes representative route selection and database establishment methods, establishes various representative working conditions based on the database and determines time proportions ; Propose a method for determining station classification thresholds, and classify all bus stations in a city or region based on the threshold; propose a method for determining weight factors for various working conditions, select representative working condition data according to weight factors, and complete the construction of urban or regional road cycle working conditions. Based on the actual road operation data of buses, the invention can realize the construction of urban regional working conditions and the prediction of unknown bus line working conditions, and improve the accuracy of constructing urban cycle working conditions.

Description

technical field [0001] The invention belongs to the construction field of buses in actual road cycle working conditions, and in particular relates to a construction method of urban bus working conditions. Background technique [0002] Vehicle driving conditions reflect the process of vehicles traveling in a specific traffic environment, and take the speed-time process as the form of expression. On the basis of collecting a large amount of measured data, the construction of actual road cycle conditions is the data support for vehicle optimization testing and simulation, an important basis for evaluating vehicle emissions, fuel consumption, control strategies, and parameter matching, and is a common core technology for automotive research. [0003] Due to the particularity of the fixed route of the bus, it is determined that its operating status is very different from that of other vehicles. At present, most of the research on the construction of urban public transport condit...
