Embodiment Construction

[0031] The present invention proposes an urban residents group transfer mode discovery system based on traffic OD data ("O" comes from English ORIGIN, pointing out the starting point of the trip, and "D" comes from English DESTINATION, pointing out the destination of the trip) including data Preprocessing module, transfer trajectory identification module, transfer hotspot area discovery module and group transfer mode mining module. In order to make the object, technical solution and advantages of the present invention clearer, each module of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] like figure 1 Shown, the present invention is concretely realized as follows:

[0033] 1. Data preprocessing module

[0034] The input data is bus card swiping data, subway card swiping data and other data sources. Firstly, valid fields are extracted, abnormal data are eliminated, and then the time of getting on and off...

Abstract

The invention discloses a system and method for discovering transfer modes of urban residents based on traffic OD data, including a data preprocessing module, a transfer trajectory identification module, a transfer hotspot area discovery module and a group transfer mode mining module; the invention establishes In a large number of real residents' bus travel card swiping data, it is robust and universally applicable. The discovery of transfer modes within the city provides data support and reasonable suggestions for the optimization of public transportation routes and dynamic vehicle scheduling.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and proposes a system and method for discovering transfer modes of urban resident groups based on traffic OD data. Background technique [0002] Public transportation is not only an economical and green way of travel for residents, but also an important means of alleviating urban congestion. According to statistics, 60% of the urban population spends at least 1 hour a day on public transportation (how many people take the bus, how many people take the subway). However, the continuous development of urban construction has led to dynamic changes in the distribution of urban functional areas and points of interest, which has changed the distribution of urban passenger flow. For example, newly built shopping malls and commercial districts will stimulate new travel needs. Therefore, how to improve residents' public travel efficiency and dynamically discover new public travel needs ...
