Abstract

INTRODUCTION

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 are 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.

METHODS

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 perspectives 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.

RESULTS

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 may be more dependent on bike-sharing systems. The declined trips reduce user contacts and transmission risk. Central urban areas have more user close contacts and higher transmission risk than suburban areas. Besides, a new concept of is proposed to decrease transmission risk and the number of idle bikes.

CONCLUSIONS

This paper is the first research focusing on both user demand and transmission risk of bike-sharing during the COVID-19 pandemic. This study evaluates the mobility role of bike-sharing during the COVID-19 pandemic, and also provides insights into curbing the viral transmission within the city.

摘要

引言

2019年冠状病毒病(COVID-19)引发了全球大流行,交通服务在冠状病毒传播中起了关键作用。尽管共享单车用户不像在公交车或地铁车厢那样处于密闭空间且人员拥挤,但他们会接触自行车表面,存在传播风险。在COVID-19大流行期间,如何满足用户需求并避免病毒传播已成为共享单车的一个重要问题。

方法

基于中国南京共享单车的出行数据,本研究从站点、用户和自行车的角度分析了疫情爆发前后的出行需求和运营管理情况。应用半对数差分模型、可视化方法和统计指标来探讨大流行期间共享单车的交通服务和风险防范。

结果

疫情防控策略大幅降低了用户需求,通勤出行下降更为显著。健康和宗教场所周边的一些站点变得更加重要。男性和老年人可能更依赖共享单车系统。出行次数的减少降低了用户接触和传播风险。中心城区比郊区有更多的用户密切接触和更高的传播风险。此外,还提出了一个新的概念来降低传播风险和闲置自行车数量。

结论

本文是第一项同时关注COVID-19大流行期间共享单车用户需求和传播风险的研究。本研究评估了COVID-19大流行期间共享单车的出行作用,也为遏制城市内病毒传播提供了见解。
