Abstract | 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. |

Abstract | This paper traces the plunge and rebound of the taxi market in Shenzhen, China through the COVID-19 lockdown. A four-week taxi GPS trajectory data set is collected in the first quarter of 2020, which covers the period of lockdown and phased reopening in the city. We conduct a spatiotemporal analysis of taxi demand using the data, and then select taxis that continued to operate through the analysis period to examine whether and how they adjusted operational strategies. We find, among other things: (i) the taxi demand in Shenzhen shrank more than 85% in the lockdown phase and barely recovered from that bottom even after the city began to reopen; (ii) the recovery of taxi travel fell far behind that of the overall vehicle travel in the city; (iii) most taxis significantly cut back work hours in response to the lockdown, and many adjusted work schedule to focus on serving peak-time demand after it was lifted; (iv) taxi drivers demonstrate distinct behavioral adaptations to the pandemic that can be identified by a clustering analysis; and (v) while the level of taxi service dropped precipitately at the beginning, it quickly rebounded to exceed the pre-pandemic level, thanks to the government’s incentive policy. These empirical findings suggest (i) incentives aiming at boosting supply should more precisely target where the boost is most needed; (ii) the taxi market conditions should be closely monitored to support and adjust policies; and (iii) when the demand is severely depressed by lockdown orders or when the market is oversupplied, taxi drivers should be encouraged and aided to use more centralized dispatching modes. |
