Although metro systems are established in many Asian cities including Chengdu, they have yet to cover every corner of a city. Understanding the transfer behavior of passengers can provide insight into achieving efficient and sustainable urban transport systems. Combining shared mobility programs with metro to improve the weaknesses of traditional feeder modes is viewed as the most promising line of business in sustainable transportation for the near future. Therefore, this study aims to comprehend the factors affecting the usage regularity of shared mobility by deepening the knowledge on endogenous and exogenous effects, and integrating two modes, namely bike-sharing and ridesourcing. Two systems are cross-compared, first in respect of their travel characteristics. Then, a binary logistic model is employed to capture the influences of trip characteristics and travel environment characteristics on their usage frequency. Researchers found that trip distance is significantly associated with users’ mode options, indicating that bike-sharing and ridesourcing mainly serve short-distance and long-distance transfer users, respectively, although some users may be confused which feeder mode to choose for the journeys of 2 km to 4 km. There were also meteorological and temporal influences, with the competition and complementation of multiple shared mobility feeder modes being likely to change under extreme weather conditions, during peak hours, or on weekends. Besides, metro-shared mobility users value the accessibility of two kinds of transport service, which is affected by the metro station and its surrounding built environment. This study and the proposed policy implications are helpful for embracing a sustainable mobility design from general optimum.

尽管包括成都在内的许多亚洲城市都建立了地铁系统，但尚未覆盖城市的每一个角落。了解乘客的换乘行为可以深入了解实现高效和可持续的城市交通系统。将共享出行计划与地铁相结合以改善传统支线模式的弱点，被视为在不久的将来可持续交通领域最有前途的业务线。因此，本研究旨在通过深化对内生效应和外生效应的认识，结合共享单车和代驾两种模式，来理解影响共享出行使用规律的因素。两个系统进行了交叉比较，首先是在它们的旅行特性方面。然后，采用二元逻辑模型来捕捉出行特征和出行环境特征对其使用频率的影响。研究人员发现，出行距离与用户的模式选择显着相关，表明共享单车和拼车服务分别主要服务于短途和长途换乘用户，尽管有些用户可能会混淆选择哪种接驳车模式。 2 公里到 4 公里。也有气象和时间的影响，在极端天气条件下、高峰时段或周末，多种共享移动支线模式的竞争和互补可能会发生变化。此外，地铁共享出行用户看重两种交通服务的可达性，受地铁站及其周边建筑环境的影响。这项研究和拟议的政策含义有助于从总体优化中采用可持续的交通设计。
