南京市无桩型共享单车出行与地铁接驳关系探析

Analysis of the Connection Between Bike-Sharing Trip and Subway in Nanjing City

共享单车在一定程度上成为城市公共交通工具的“接驳者”。采用空间网络分析方法,对南京市共享单车出行与地铁接驳关系进行研究,分析地铁站周边的共享单车变化特征和汇源特性,探究了共享单车对地铁站可达范围的影响。研究表明:地铁站周边共享单车汇源类型主要分为输出型、汇入型、早输晚入型、早入晚输型以及均衡型5种类型,其中早输晚入型与早入晚输型站点主要服务于通勤出行;共享单车扩大了地铁的服务范围,共享单车为居民出行提供了一种新的选择,使其出行方式更加便捷,缩短了其前往地铁站的出行时间。

To a certain extent shared bikes have become the connections of urban public transportation.In this paper, the spatial network analysis method is adopted to study the relationship between bike-sharing trips and subway in Nanjing, analyze the variation characteristics of the number of shared bikes around subway stations, discuss the characteristics of sink and source for the shared bikes around subway stations, and analyze the influence of shared bikes on the accessibility range of subway stations.The research shows that the concentrated area for bike-sharing trips and subway connections occurs within a distance of 1200 meters from the subway station.The sink and source for bike-sharing around subway stations are mainly divided into five types: output type, import type, early entry and late entry type, early entry and late entry type, and balanced type. Among them, he stations of early entry and late entry type and early entry and late entry type mainly serve for commuting.Shared bikes have expanded the service scope of subway stations, making it faster for residents to get to subway stations and shortening travel time.
