초록

최근 10여년 사이 컴퓨터의 성능 향상과 기술의 발전으로 현실에서 일어날 법한 여러 가지 상황들을 가상환경을 통해 선험 할 수 있게 되었다. 교통 분야에서도 가상환경을 활용하여 다양한 시나리오 하에서 운전자의 행태를 파악하는 연구들이 많이 수행되고 있다. 본 연구는 운전 시뮬레이터를 이용하여 철도 건널목 안전수행 평가를 위한 실험을 실시하였다. 세 종류의 ITS 안전장치들이 운전자에게 어떠한 영향을 주는지를 파악하였고, 실험에 참가한 운전자들에게 각 안전장치에 대한여러 가지 설문조사를 진행하였으며, 이에 대한 평가가 이 논문의 목적이다. 각 실험 참가자들은 각 20여 분간 3 번의 운행을 하게 되는데, 무작위 순서로 2번은 기존 철도 건널목을 건너고, 1번은 ITS 안전창치를 사용하면서 운행하였다. 실험 전, 참가자들은 기존 철도건널목이 안전하지 않아 보인다고 답하였고, 자신, 혹은 타인들이 출동사고를 일으킬 확률이 높을 것 같다고 응답하였다. 실험 후, ITS 안전장치를 이용하는데 어려움이 있는지에 대한 질문에는 ITS 3 (도로 발광 표지병)을 이용하였을 때, 가장 수월한 적응도를 보였다. 또한, ITS 안전장치는 3종 철도건널목에서 큰 효과를 나타낸다고 응답하였다.

In the last decade, various situations were simulated through virtual environment due to rapid improvement of computer capability and technology. Transportation engineering also has adopted the virtual environment facility in order to identify drivers behaviour under various circumstances. This study aims to evaluate driver reactions to the introduction of new ITS interventions at railway crossings (RLX) in driving simulator. Three ITS safety devices were used to figure out how drivers reacted to them. In addition, a survey was conducted to find participants' work load and acceptance of the technology. The ultimate purpose of this paper is to evaluate ITS safety devices in various aspects. Each participant made 3 runs (2 baselines, 1 ITS randomly) for approximately 20 minutes each. The participants answered that current railway crossings did not look safe prior to experiment. They responded that the use of ITS technologies were easy and the technologies were more effective on passive railway crossings.
