摘　　要：近年来,共享单车作为一种低碳环保的新兴出行方式得到广泛使用,能够有效解决居民出行“最后一公里”问题。由于其使用环境开放、有利于保持社交距离等特点,突发公共卫生事件背景下使用共享单车出行的特征成为研究热点。文章以芝加哥市共享单车系统Divvy Bikes为研究对象,基于公开数据集,对2021年和2022年芝加哥共享单车出行时空特征进行分析,结果发现:第一,2022年共享单车骑行量相比2021年有明显下降,但其下降程度低于同时期的地面公交和轨道交通客流量;第二,在时间特征上,尽管受到突发公共卫生事件的影响,共享单车骑行仍然呈现明显的早晚高峰现象,骑行时长以5~10分钟为主;第三,在空间特征上,骑行距离以短中距离为主,骑行热点区域主要集中在芝加哥市中心区域并呈现由市中心向郊区扩散的趋势。In recent years,bike-sharing has been widely used as a low-carbon and environmentally friendly emerging travel mode,which can effectively solve the"last kilometer"problem of residents'travel.Due to its characteristics such as open use environment and being good for social distancing,the characteristic of using bike-sharing to travel in the context of public health emergencies has become a hot topic.Based on the public data set,this paper analyzes the spatiotemporal characteristics of bike-sharing travel in Chicago in 2021 and 2022.The results show that in 2022,bike-sharing rides decreased significantly compared with 2021,yet the decrease of bike-sharing ridership was lower than buses and rail,that in terms of temporal characteristics,despite the impact of public health emergencies,bike-sharing riding still presented an obvious morning and evening peak phenomenon with 5~10 minutes cycling duration,and that in terms of spatial characteristics,the cycling distance was mainly short or medium,and the cycling hotspots appeared in the downtown area of Chicago and showed a trend of spreading from the downtown area to the suburbs.
