Studies on bike-share programs have dramatically increased during the past decades. While numerous studies have examined various factors affecting bike-share demand at the station-level, few attempts have been made to understand bike-share ridership at the origin-destination (OD) level due to technical difficulties. The objective of this study is to examine whether existing public transit characteristics affect bike-share ridership at OD-level. We combined three datasets: (1) bike-share ridership data, (2) land-use and bike-transit infrastructure, and (3) bike-transit route characteristics between OD pairs of bike stations. Zero-inflated negative binomial (ZINB) regression models were used for the analysis. Our results showed that the travel distance between OD bike stations, land-use compositions, and the existence of bike-friendly infrastructures were significant factors determining bike-share ridership at the OD-level. In particular, a longer duration of public transit trips than bike-share, and more transit transfers, were associated with bike-share ridership. Further, this study showed that bike-share and public transit might compete with or promote each other, even within the city. The study's findings suggest that the relative efficiency of bike-share compared to public transit is highly associated with bike-share demand and help to increase the utility of bike-share system in response to several limitations of existing public transit networks.

在过去的几十年中，有关自行车共享计划的研究急剧增加。尽管许多研究已经研究了影响车站一级自行车共享需求的各种因素，但是由于技术上的困难，人们很少尝试了解始发站（OD）一级的自行车共享乘车人数。这项研究的目的是要检查现有的公共交通特征是否会在OD级别上影响共享自行车的出行。我们合并了三个数据集：（1）自行车共享出行数据，（2）土地使用和自行车过境基础设施，以及（3）OD站对之间的自行车过境路线特征。零膨胀负二项式（ZINB）回归模型用于分析。我们的结果表明，OD自行车站之间的行驶距离，土地使用成分，自行车友好基础设施的存在是决定OD级别自行车共享乘车率的重要因素。尤其是，与单车共享相比，公共交通出行的时间更长，而公交换乘次数更多，则与单车共享的骑行相关。此外，这项研究表明，即使在城市内部，共享自行车和公共交通工具也可能相互竞争或互相促进。这项研究的发现表明，与公共交通相比，自行车共享的相对效率与自行车共享需求高度相关，并有助于应对现有公共交通网络的一些局限性，从而提高自行车共享系统的实用性。与骑自行车的人有关。此外，这项研究表明，即使在城市内部，共享自行车和公共交通工具也可能相互竞争或互相促进。这项研究的发现表明，与公共交通相比，自行车共享的相对效率与自行车共享需求高度相关，并有助于应对现有公共交通网络的一些局限性，从而提高自行车共享系统的实用性。与骑自行车的人有关。此外，这项研究表明，即使在城市内部，共享自行车和公共交通工具也可能相互竞争或互相促进。这项研究的发现表明，与公共交通相比，自行车共享的相对效率与自行车共享需求高度相关，并有助于应对现有公共交通网络的一些局限性，从而提高自行车共享系统的实用性。
