Abstract

Pedestrians are the most vulnerable road users. According to one analysis of traffic accidents over a five year period, pedestrians accounted for about 40% of all road traffic deaths in South Korea. Although some policy and engineering approaches have been taken to reduce and prevent traffic accidents, the annual accident change rate is -0.7%, which is insufficient. This study verifies the effectiveness of presenting visual messages to pedestrians and the effect from adding auditory messages to the visual messages. The experiment was conducted on crosswalks adjacent to an intersection, and safety behaviors were recorded for a total of 898 pedestrians and considered sufficient. As a result of the study, overall pedestrian safety behavior improved when both visual and auditory messages were presented, rather than just visual messages. Therefore, the results indicate it is more effective to provide a mixed visual/auditory form of messages, rather than providing single stimulus messages.

최근 5년간 보행자 교통사고 분석 결과, 전체 교통사고 사망자 중 보행자가 차지하는 비중은 약 40%를 차지하여 교통안전에 매우 취약한 상황이다. 교통사고를 감소 및 예방하기 위한 여러 정책적·공학적 접근이 이루어졌으나 연 평균 사고 변화율은 -0.7%로 아직 실효성이 미흡하다고 볼 수 있다. 교통사고 예방을 위한 선행연구에서는 주로 운전자를 대상으로 한 연구가 실시되어 보행자의 안전에 대한 연구는 미흡하였다. 이에 본 연구에서는 보행자에게 시각적 메시지를 제시하는 것과 시각적 메시지에 청각적 메시지를 추가하여 제시하는 것에 대한 효과성을 검증하였다. 실험은 교차로에 인접한 횡단보도에서 실시되었으며 총 898명의 보행자에 대한 안전 행동이 수집되었다. 연구 결과 시각적 메시지만을 제시하는 것보다 청각적 메시지를 혼합하여 제시하였을 때 보행자의 전반적 안전행동은 더 향상된 것으로 나타났다. 따라서 단일 자극 형태의 메시지를 제공하는 것보다 혼합된 형태의 메시지를 제공하는 것이 더 효과적이라는 결과를 도출하였다.
