Abstract

현재 고속도로 터널 내 돌발상황 정보는 라디오 재난경보방송 및 VMS (Variable Message Sign)를 통해 터널 내에서만 제공되고 있다. 따라서, 터널 입구부 사고의 경우, 운전자는 돌발상황 정보 서비스를 받지 못하며, 이에 대한 대처가 늦어져 사고 위험성이 증가하게 된다. 한편, 터널 진입구간 라디오 기반 돌발상황 정보 서비스는, 해당 문제점에 대한 좋은 해결방안이 될 수 있다. 따라서, 본 연구의 목적은 라디오 기반 재난경보방송을 실시하기 전 일반 운전자들의 자동 재난경보방송 기술에 대한 생각과 수용성을 분석하는 것이다. 총 762명의 운전자를 대상으로 수행된 설문조사 결과에 대하여 구조방정식을 적용하였으며, 새롭게 도입될 기술과 서비스에 대한 수용성 분석을 진행하였다. 결과적으로 운전자 특성(연령, 운전빈도, 운전경력 등), 교통정보 활용도, 교통정보 유용성이 자동 정보제공 기술 및 라디오 재난경보방송 수용성에 긍정적인 영향을 미치는 것으로 나타났다. 본 연구결과는 새로운 재난경보방송 시스템의 검토 및 적용에 대한 기반자료로 활용될 것으로 기대된다.

Currently, roadway operation agencies provide interior zones of tunnels with emergency information including crash, fire, and vehicles’ stop, through state-of-the-art technologies such as variable message signs and radio-based broadcast systems. However, when coping with an emergency in tunnel interior zones, such information could be too late for drivers to access. A radio-based emergency alert system at the access zones of freeway tunnels, on the other hand,could be a good alternative for solving this problem. Therefore, the objective of this study is to assess user acceptability of such an alternative system. To carry out this study, an online survey was conducted on 762 drivers, and the survey results were analyzed using a structural equation modeling to identify factors affecting acceptability of the proposed system. As a result, driver characteristics such as age group, driving frequency, and driving career, utilization of conventional traffic information, and usefulness of conventional traffic information have a positive impact on acceptability. It is expected that the findings of the study will be a basis to effectively address and deploy a new emergency alert system at the access zones of freeway tunnels.
