Abstract

The number of traffic accidents in Korea has been increasing since 2014. In most school zones, safety signs are installed to prevent children's traffic accidents. However, it has been known that the effects of those signs are not significant. A variable message sign(VMS), one of the components of Intelligent Transport System(ITS), has emerged as an alternative method. Therefore, this study examines relative effects of two different VMS messages(Timely vs. Continuous) on vehicle speed. Experiments were conducted in two school zones. 6,676 vehicles were measured for speed limit compliance. A counterbalanced multiple baseline design was adopted. The results showed that both types of message are effective in reducing the speed of vehicle. Specifically, A timely message was more effective in slowing down vehicle speed and improving speed limit compliance than a continuous message. The present study suggested that a VMS with human factors can be effective.

대한민국에서 어린이 교통사고 발생 건수는 2014년 이후로 증가하고 있으며 이에 대한 안전대책이 시급한 실정이다. 대부분 스쿨존에서 어린이 교통사고 예방을 위해 안전표지 등을 설치 및 운용하고 있다. 하지만 그 효과성은 미미하여 대안으로 ITS의 구성요소 중 하나인 VMS가 대두되고 있다. 이에 본 연구는 상이한 VMS 메시지 제시 유형이 주행차량 속도에 미치는 효과를 비교 검증하였다. 실험은 서울 소재 2곳의 스쿨존에서 진행되었으며 총 6,676대의 차량의 속도가 측정되었으며 역균형 ABC 다중기저선 설계가 적용되었다. 연구 결과, 두 메시지 유형 모두 주행차량속도 감소에 효과적이었다. 구체적으로, 운전자들에게 적시적으로 제공되는 메시지가 상시적으로 제공되는 메시지보다 주행차량 감속 및 속도 준수에 효과적인 것으로 나타났다. 본 연구 결과를 바탕으로 인적요인을 고려한 VMS 운용방안 및 설계에 대해 모색해 볼 수 있을 것이다.
