Embodiment Construction

[0082] This embodiment is specifically applied to Beijing Xianglong Public Transport Group. Based on the card swiping data returned on January 4, 2018, the dynamic card swiping data of bus passengers whose bus line number is 104 and vehicle number is 7153 is extracted as an example. Dynamically calculate the dynamic full load rate of the vehicle for a certain period of time.

[0083] The present embodiment comprises the following steps:

[0084] Step 1: Basic data preprocessing

[0085] Match and analyze the returned bus GPS data and the bus line data table to obtain the final IC card swiping data integration table for bus passengers. Taking the passenger card swiping data of line number 104 and vehicle number 7153 as an example, the results of the bus passenger IC card swiping data integration table are shown in Table 5.

Abstract

The invention discloses a public transport real-time load factor computation method based on bus multi-source data. The method comprises the preprocessing card-swiping data of bus passengers processing method; association technology of public transport GPS data and public transport line basic data; and public transport real-time load factor computation method based on the bus multi-source data. The method comprises the following steps: firstly performing the preprocessing of extracting, screening and rejecting the bus dynamic IC card data and the GPS data; extracting the public transport operation state information through the association of the GPS data and public transport line basic data; and meanwhile, dynamically computing a vehicle sampling expansion coefficient based on the historiccard swiping data in different lines and determining the dynamic load factor checking interval threshold; and finally real-time accessing a completely integrated dynamic card swiping data table through the computer technology. The passenger card swiping data, the bus GPS data and like dynamic data, the public transport line basic data, the bus physical parameter and like static data are integrated, thereby constructing a computation model of the public transport real-time load factor.

Description

technical field [0001] The invention belongs to the technical field of intelligent public transportation and the field of public transportation data mining, and in particular relates to a method for calculating the real-time full load rate of public transportation vehicles based on multi-source data of public transportation. Background technique [0002] In recent years, with the introduction of the concept of public transportation city, the development status and ride comfort of public transportation have been paid more and more attention by traffic decision-makers and travelers, and the degree of public transportation congestion has become the hot spot that people pay the most attention to. Therefore, dynamically obtaining the real-time full load rate of buses can provide important bus operation information for bus travelers and operation managers, helping travelers to make travel decisions and operation managers to carry out dynamic optimal bus dispatching. [0003] Most ...
