Should bike sharing continue operating during the COVID-19 pandemic? Empirical findings from Nanjing, China

TL;DR

This study examines how bike sharing in Nanjing was affected during COVID-19, revealing demand reduction, shifts in station importance, and proposing user distancing to mitigate transmission risk.

Contribution

It provides empirical analysis of bike sharing demand and operation changes during COVID-19, introducing a new user distancing concept to reduce transmission risk.

Findings

Demand sharply decreased during the pandemic.

Commuting trips declined more significantly.

User distancing can help activate idle bikes and reduce transmission.

Abstract

Coronavirus disease 2019 (COVID-19) has triggered a worldwide outbreak of pandemic, and transportation services have played a key role in coronavirus transmission. Although not crowded in a confined space like a bus or a metro car, bike sharing users will be exposed to the bike surface and take the transmission risk. During the COVID-19 pandemic, how to meet user demand and avoid virus spreading has become an important issue for bike sharing. Based on the trip data of bike sharing in Nanjing, China, this study analyzes the travel demand and operation management before and after the pandemic outbreak from the perspective of stations, users, and bikes. Semi-logarithmic difference-in-differences model, visualization methods, and statistic indexes are applied to explore the transportation service and risk prevention of bike sharing during the pandemic. The results show that pandemic control strategies sharply reduced user demand, and commuting trips decreased more significantly. Some stations around health and religious places become more important. Men and older adults are more dependent on bike sharing systems. Besides, the trip decrease reduces user contact and increases idle bikes. And a new concept of user distancing is proposed to avoid transmission risk and activate idle bikes. This study evaluates the role of shared micro-mobility during the COVID-19 pandemic, and also inspires the blocking of viral transmission within the city.
