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] Such as 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 ...

Abstract

The invention discloses an urban resident traffic transfer mode discovery system and method based on urban traffic OD data. The system includes a data preprocessing module, a transfer trajectory identification module, a transfer hotspot area discovering module and a group transfer mode exploring module. The system and method provided by the invention are based on a large amount of one-card swiping data during real resident bus travel, and have robustness and general applicability; the discovery of the urban region traffic transfer mode provides data support and reasonable suggestions for the public transport line optimization and the 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 ...
