Abstract

Public transportation serves as a vital component of urban infrastructure, providing an essential mobility option for large number of citizens. However, limited understanding of travel factors in public transportaion has impaired the equilibrium of its supply and demand, resulting in various societal challenges. To address this issue, this study aims to identify the factors affecting travel patterns in different modes of public transportation from a multimodal mobility perspective. In order to complement the limitations of existing studies that explored the causal relationships between travel variables and individual modes of transportation, an integrated analysis of mode-specific travel, transfer travel, and overall travel within a multimodal framework is proposed. In this context, the analysis examined the travel patterns and factors for each mode of transportation, and revealed the distinct functions of each mode within urban mobility. Notably, with the same set of independent variables applied across transportation modes some variables exhibited regression coefficients with opposite signs depending on the mode. This implies that specific travel factors do not influence all modes of transportation in the same way, highlighting the importance of considering the roles and characteristics of each mode in an integrated manner when implementing transportation policies. The results of this study are expected to contribute to a better understanding of public transportation travel and provide meaningful evidence for the formulation of practical transportation policies.

대중교통은 도시의 중요한 기간 시설로 다수의 시민이 이용하는 필수 교통수단이다. 그러나 대중교통 통행 요인에 대한 이해의 한계로 대중교통 수요와 공급 간의 불일치가 발생하고 있으며 이로 인한 사회적 문제가 발생하고 있다. 이에, 본 연구는 멀티모달 모빌리티 기반의 대중교통수단별 통행 요인을 도출하고자 한다. 기존의 연구들은 대중교통 통행량 및 통행 요인을 이해하기 위해 각종 모델링 기법을 적용하였으나, 멀티모달 모빌리티 관점에서 각각의 교통수단별 통행, 환승 통행, 전체 통행을 통합적으로 분석한 사례는 드물다. 이러한 배경에서 본 연구는 통합적 틀에 기반하여 대중교통수단별 통행 패턴과 요인을 도출하였으며 이를 통해 도시 내 모빌리티에 있어 개별 대중교통수단의 기능을 살펴볼 수 있었다. 특히, 각각의 대중교통수단별 통행에 대해 동일한 독립 변수를 적용했음에도 불구하고 일부 독립 변수는 교통수단에 따라 통행에 미치는 영향이 상반되게 나타났다. 이는 특정 통행 요인이 모든 교통수단에 동일하게 작용하지 않음을 의미하며, 교통 정책 실행에 각 교통수단의 역할과 특성을 통합적으로 고려하는 것이 중요함을 의미한다. 본 연구의 결과는 대중교통을 이용한 통행에 대한 이해와 실제 교통 정책 수립에 유의미한 근거 자료를 제시할 것으로 기대된다.
