The COVID-19 pandemic led to the adoption of many unprecedented measures to slow down the spread of the virus. Such measures have greatly impacted the entire transportation system and individuals’ travel behaviors. This paper evaluates the impacts of COVID-19 related policies, including the lockdown and the first lockdown ease on the usage of public bicycle share in London using interrupted time series approach. Our results indicate that the UK’s lockdown led to an immediate decrease in the London Cycle Hire (LCH) usage, while the first lockdown ease had no statistically significant immediate impacts. Moreover, during the lockdown period, the LCH usage showed an increasing trend and the first lockdown ease led to a much larger increase rate. Such impacts vary by the trip characteristics (i.e., occurring period and trip duration). The morning peak trips and short duration trips maintained a lower usage level during the lockdown and the lockdown ease period. On the contrary, the number of other LCH trips were much larger than that in normal days. Furthermore, the impacts on the LCH stations near the rail stations, hospitals, and parks also varied differently. The LCH trips near the rail stations reduced more after the imposition of the lockdown policy while those near the hospitals reduced less. The LCH stations near the parks had a much higher increase rate during the lockdown and the lockdown ease period than the general level. Our results provide practical implications for the policy makers and operators of the public bicycle share system.

COVID-19 大流行导致采取了许多前所未有的措施来减缓病毒的传播。这些措施极大地影响了整个交通系统和个人的出行行为。本文使用间断时间序列方法评估了 COVID-19 相关政策的影响，包括锁定和首次锁定对伦敦公共自行车共享使用的缓解。我们的结果表明，英国的封锁导致伦敦自行车租用 (LCH) 使用率立即下降，而首次封锁放松并未产生具有统计意义的直接影响。此外，在锁定期间，LCH 使用量呈上升趋势，第一次锁定放松导致更大的增长率。这种影响因出行特征（即发生时间和出行持续时间）而异。在锁定和锁定放松期间，早高峰出行和短途出行保持较低的使用水平。相反，其他LCH的出行次数远多于平时。此外，对靠近火车站、医院和公园的LCH车站的影响也各不相同。实施封锁政策后，火车站附近的 LCH 出行减少较多，而医院附近的出行减少较少。公园附近的 LCH 站点在锁定期间和锁定放松期间的增长率远高于一般水平。我们的研究结果为公共自行车共享系统的政策制定者和运营商提供了实际意义。其他LCH出行次数远大于平时。此外，对靠近火车站、医院和公园的LCH车站的影响也各不相同。实施封锁政策后，火车站附近的 LCH 出行减少较多，而医院附近的出行减少较少。公园附近的 LCH 站点在锁定期间和锁定放松期间的增长率远高于一般水平。我们的研究结果为公共自行车共享系统的政策制定者和运营商提供了实际意义。其他LCH出行次数远大于平时。此外，对靠近火车站、医院和公园的LCH车站的影响也各不相同。实施封锁政策后，火车站附近的 LCH 出行减少较多，而医院附近的出行减少较少。公园附近的 LCH 站点在锁定期间和锁定放松期间的增长率远高于一般水平。我们的研究结果为公共自行车共享系统的政策制定者和运营商提供了实际意义。实施封锁政策后，火车站附近的 LCH 出行减少较多，而医院附近的出行减少较少。公园附近的 LCH 站点在锁定期间和锁定放松期间的增长率远高于一般水平。我们的研究结果为公共自行车共享系统的政策制定者和运营商提供了实际意义。实施封锁政策后，火车站附近的 LCH 出行减少较多，而医院附近的出行减少较少。公园附近的 LCH 站点在锁定期间和锁定放松期间的增长率远高于一般水平。我们的研究结果为公共自行车共享系统的政策制定者和运营商提供了实际意义。
