Abstract

With the spread of COVID-19 and the government policy of social distancing, the demand for subways and buses is decreasing, whereas the demand for public bicycles and personal transportation is increasing. Hence, research is needed to understand the characteristics of this phenomenon and to prove the statistical reliability of the correlation between the subway and shared bicycle demands. In this study, the correlation between the number of confirmed COVID-19 cases and the replacement rate of subway and public bicycle demands was examined, but the statistical significance was not significant. However, during the period of September to December 2020, in which the number of confirmed COVID-19 cases in Seoul started to increase rapidly, there was a correlation between the number of confirmed COVID-19 cases and the replacement ratio. If the number of confirmed COVID-19 cases increases by more than a certain number, public bicycles are expected to play a significant role as alternates to the subways. It is expected that the role of public bicycles will increase, and that it is possible to suggest the direction of transportation operation and policy establishment for the continuation of COVID-19 countermeasures in field demonstration after elementary technology development. It is also expected that this study will suggest a direction for future development and policymaking.

코로나19 확산과 함께 정부 정책인 사회적 거리두기에 따라 지하철 및 버스 통행량은 감소하는 반면 공유자전거 및 개인형 교통수단 통행량은 증가하는 추세이다. 이 같은 현상에 대한 객관적인 해석과 특성을 파악하고 지하철과 공유자전거 통행량의 상관관계를 통계적으로 입증하는 연구가 필요하다. 본 연구에서는 코로나19 확진자수와 지하철과 공유자전거 통행량의 대체비율간 상관관계를 살펴보았으며, 통계적 유의성은 크지 않은 것으로 분석되었다. 그러나 2020년 9월~12월의 서울시 코로나19 확진자수가 급격하게 증가하기 시작한 기간에는 서울시 코로나19 확진자수와 대체비율간 상관성을 보이는 것으로 나타났다. 이는 코로나19 확진자수가 일정규모이상 증가하면 공유자전거가 지하철의 대체교통수단으로서 역할이 확대됨을 의미한다. 또한 코로나 19에 대응 가능한 교통수단 운영 및 정책 수립의 방향성 제시가 가능할 것으로 기대된다.
