Embodiment Construction

[0038] The technical solutions of the present invention will be further described below with reference to the accompanying drawings. In the embodiment of the present invention, the IC card data used is provided by Nanjing Public Bicycle Company and Nanjing Metro Company. In this embodiment, the method of the present invention is further described by taking the subway IC card data and the public bicycle IC card data on March 9, 2016 as an example.

[0039] refer to figure 1 , First, obtain the original data of public bicycle IC card and subway IC card, and extract valid information from the two types of original data respectively. In the original data, a complete public bicycle swiping record contains 15 parts: card swiping date, card number, name of the borrowing station, number of the borrowing station, longitude of the borrowing station, latitude of the borrowing station, borrowing time, borrowing pile number , Public bicycle vehicle number, return station name, return stati...

Abstract

The invention discloses a method for measuring and determining a public bike connection radius at a subway station based on IC card data. The method comprises the steps of performing effective information extraction, pre-processing, fusion, sequencing and filtration on original data of both public bike IC cards and subway IC cards to sieve possible transfer data pairs; calculating a bike-returningand station-entering time interval, an station-leaving and bike-borrowing time interval and a distance between the subway station and the public bike station; determining the maximum transfer time interval and the maximum transfer distance; identifying subway and public bike transfer data; calculating a riding distance of the public bike in the corresponding transfer data of the subway station based on the identified transfer data; drawing a public bike riding distance-cumulative frequency scatter curve; and after the curve is fitted, measuring and determining the public bike connection radius of the subway station by applying a method of finding the inverse function of the fitting function. The method for measuring and determining the public bike connection radius at the subway station based on the IC card data lays a firm foundation for research in the aspects such as address selection and configuration of the public bike station.

Description

technical field [0001] The invention belongs to the field of data mining of public bicycle IC cards and subway IC cards, and particularly relates to a method for determining the connecting radius of public bicycles in subway stations based on IC card data. Background technique [0002] Under the background of a series of problems faced by the development of motorized transportation and the development needs of low-carbon transportation, the public transportation system can alleviate the contradiction between transportation supply and demand and improve the efficiency of transportation operation. In order to reduce the pressure of road traffic, many cities have adopted the policy of giving priority to the development of public transportation, and put forward a series of guiding measures. [0003] As a kind of public transportation, rail transit can significantly improve the transportation capacity and transportation efficiency of urban transportation. The operation experienc...
