ABSTRACT

Competitiveness is an important factor for the sustainable mobility of an integrated multimodal system. In this study, we explore and answer the question concerning what makes bike-sharing trips more competitive than bus trips. The empirical analysis is conducted using transit smartcard and bike-sharing GPS data collected in Seoul, and logistic regression models were developed to understand the factors contributing to the bike-sharing being more competitive than buses. The findings demonstrate that bike-sharing is not only a complementary mode but could also be competing with buses at certain extents. The results indicate that bike-sharing trips can be more competitive than bus trips with longer detours or when the speed of the bus is reduced, such as peak-time periods and short trips. Travel time of bike-sharing is more reliable than bus’s during peak times, while the bike lanes contribute to keeping bike-sharing more competitive even during off-peak times.

摘要

竞争力是综合多式联运系统可持续流动性的重要因素。在这项研究中，我们探讨并回答了有关是什么让共享单车旅行比公共汽车旅行更具竞争力的问题。实证分析使用在首尔收集的公交智能卡和共享单车 GPS 数据进行，并开发了逻辑回归模型以了解导致共享单车比公共汽车更具竞争力的因素。研究结果表明，共享单车不仅是一种互补的模式，而且在一定程度上也可以与公共汽车竞争。结果表明，共享单车出行比绕道较长或公交速度降低的公交出行（如高峰时段和短途出行）更具竞争力。
