Abstract

Recently, with the widespread expansion of convergence based on digital connectivity, the transportation and mobility fields are rapidly changing, and research related to this is also diversifying. This study aims to analyze the research trends in the mobility field and identify key research areas and topics. Topic modeling analysis has been proved as a useful approach for analyzing the research trends. The abstracts of 142 research papers concerning mobility from the Korean academic citation index were analyzed, derived 9 research topics and linked to 6 key elements of research framework. The result showed that 'Advanced vehicle and transportaion technology' and 'Linkage and integrated services among means for mobility' were most actively studied research fields. It also found that research on insurance, law, regulation for securing user's safety and conflict-resolving with the existing industry has been conducted.

최근 디지털 연결성 기반의 융합이 광범위하게 확대되면서 교통 및 모빌리티 분야가 빠르게 변화하고 있으며 이와 관련된 연구도 다양화되고 있다. 본 연구의 목적은 모빌리티 분야의 연구 동향을 분석하고 핵심 연구영역과 주제를 파악하는 것이다. 토픽 모델링 분석은 연구 동향을 파악하는 데 유용한 것으로 입증된 기법이다. 모빌리티를 키워드로 KCI 학술지에서 142편의 논문 초록을 분석하여, 9개의 토픽을 도출하고 스마트 모빌리티 연구의 6개 핵심 요소와 연계하였다. 이를 통해 자율주행을 앞세운 차량 및 수송 기술 분야와 MaaS로 대표되는 교통수단 간 연계 및 통합서비스 분야에 관한 연구가 가장 활발한 것과 사용자의 안전을 확보하기 위한 보험, 법률, 제도, 그리고 기존 산업과의 갈등 해소 등에 관한 연구가 진행되고 있는 것을 확인하였다.
