摘　　要：近年来,中国城市中共享电单车出行在共享主动交通(Shared Active Transportation,SAT)出行中的比例迅速增加。在地铁站附近的共享电单车出行成为了轨道加慢行出行模式中的一种方式。但是,由于数据获取的限制和换乘出行识别的技术限制,现有研究对中国城市地铁站附近共享的电单车的出行特征的讨论尚不充分。本研究以共享电单车和共享单车出行特征比较为框架,对比了出行目的地可达性,时辰分布和出行产生率等指标。研究基于距离每个地铁站50米以内的订单信息展开,利用指标数值比较和双样本t检验,对距离、时间和范围的差异进行了描述性分析。时辰分布和出行产生率根据典型工作日分小时和位置汇总,并利用分层聚类方法对结果进行聚类。结果表明,共享电单车将地铁站的可达性从800米扩展到2000米。与共享单车不同,共享电单车可能会在沿轨道走廊方向和地铁具有客流竞争关系。共享电单车的出行目的也并不局限于通勤出行,不同地铁站的出行产生率有所差异。本研究提供了共享电单车的基本出行特征绩效指标,以及与共享单车出行特征差异比较结果。研究结果可对共享电单车和地铁的接驳提供政策建议,并可能对中国城市的公交导向(TOD)站点级设计提供借鉴。Trips Using Sharing e-bikes account for a rapidly growing ratio among all Shared Active Transportation(SAT) trips in China cities.The riding of sharing e-bikes before and after taking metro contribute to the mode of “Rail+Bike&Ped”.However,the revealed travel patterns on sharing e-bikes close to metro stations in China cities haven’t been thoroughly investigated due to the limitation on data access and transfer trips identifications.This study fills the research gap by framing a travel pattern comparison between bike-sharing services(BSS) and EBSS(e-bike-sharing services) on accessibility,hourly trips distributions,and trip generation rate.Trips egress or arrive areas within 50 meters from each metro stations are calculated.The study conducts a descriptive analysis on the differences on distance,duration,and concave hull at a station scale based on the results of net differences and two-sample t tests.Hourly trips distribution and trip generation rate are aggregated based on hours of a day and locations.The aggregated results are clustered using hierarchical clustering method.Results indicate that EBSS expands the accessibility of metro stations from 800 meters to 2000 meters.Different from BSS,EBSS might compete with grounded transit and metro along transit corridors.EBSS attracts more none home-based trips at mid of days.Trip generation rates vary at metro stations.This study provides fundamental travel performance results of EBSS and the related differences with BSS.The findings might bring policy implications on the mode of EBSS and metro transfer and possible impact on Transit-oriented Development(TOD) station-level design in China cities.
