Abstract

The purpose of the present study was to compare and analyze the differential effects of in-vehicle electronic device usage types(searching for targeted destinations in navigational purpose, watching TV in entertain purpose, and dialing a cellular-phone in phone-usage purpose) on driver's front-to-rear-end collision avoidance behavior, and to find effective collision warning format for this behavior. The result indicated that (1) the drivers showed more impaired collision avoidance performances when they were asked to search the name of targeted destination than the other task requirements, and (2) auditory warning appeared to be most effective among the other types of warning. In particular, it was suggested that the "Visual-Only" collision warning could induce most undesirable result when the drivers were engaged in both visual and auditory information processing.

본 연구는 다양한 전자기기 사용 유형이 추돌 가능상황에서 운전자의 추돌회피 행동에 대해 어떠한지 상대적으로 평가하고, 이러한 추돌 가능 상황에서 운전자의 추돌 회피를 위한 가장 효과적인 추돌 경고 형태가 무엇인지 검토하는 것을 목적으로 수행되었다. 선행차량과의 추돌비율과 추돌회피를 위한 최초의 반응시간을 종속 측정치로 사용하여 분석한 결과, (1) 다양한전자기기 사용과제 유형 중에서 항행을 위한 목적지 검색과제가 다른 과제들(TV 시청 혹은 휴대전화 사용)에 비해 상대적으로 더 높은 추돌비율을 보였고, (2) 이러한 추돌을 방지하는데 청각경고의 형태가 가장 효과적이라는 것이 발견되었다. 특히, 운전 과제 자체뿐만 아니라, 전자기기와의 다양한 상호작용이 주로 시각적 부하를 초래하는 과제들이라는 점을 감안하면 추돌방지를 위한 경고 형태 중에서 시각경고 형태는 상대적으로 그 효과성이 감소될 수 있다는 것이 시사되었다.
