作为地铁接驳手段的公共自行车使用特性分析

本文以苏州公共自行车为研究对象，利用刷卡数据及问卷调查数据分析公共自行车作为地铁接驳手段的使用特性.研究发现，地铁型站点公共自行车的用车时长较短且较为离散，与其他类型站点有显著差异.在接驳地铁的出行者中，公共自行车经常使用者的平均学历较高，也非低收入人群.利用离散选择模型分析地铁接驳方式选择行为可知，接驳方式使用时间是最重要的影响因素，年龄、职业和出行目的等对公共自行车的选择均有显著影响.研究还发现，经常使用公共自行车的出行者在接驳地铁时同样也倾向于选择公共自行车，而不使用者则倾向于选择步行或公交车.

Characteristics of Public Bicycle as Means of Access/Egress for Metro

This paper aims to estimate various factors influencing the usage of public bicycle as means of access to or egress from metro. By analyzing the smart-card data from the public bicycle system of Suzhou, the statistical test implies that bicycles at depots located near a metro station are much more frequently shared and their average trip time is shorter and more dispersed than those at other depots. The data gained from the questionnaire survey in the city show that regular users of public bicycle possess better education and higher income than rare users and non-users. A multi-Logit model is also developed to predict access/ egress mode choice behaviors for metro. The result reveals that riding time of modes obviously affects the choice. Furthermore traveler’s attributes such as age, profession, and trip purpose significantly influence their choice for public bicycle. It is also proved that regular users similarly prefer a public bicycle for connecting metro, while non-users are inclined for buses or walking.
