Abstract

Interest in micro cars is growing around the world, and policy support for micro cars has been increasing in Korea. It is important to meet minimum safety standards for the operation of micro cars on roads due to concerns around micro car safety and the limited driving range of micro cars. In this study, visibility experiments that included safety identification of micro cars were conducted to try and prevent a decrease in driver reaction time. Safety identification lights were installed to the rear of a micro car, and the visibility and discomfort of the vehicle were evaluated to determine whether the micro car was safe to drive on an expressway. As a result, the installation effect of Micro car which install safety identification lamp was found when joining the point at an acceleration lane of the grade separation intersection, and that light on/off could be effective when entering an expressway. If the micro car operation plan proposed in this study is applied, the safety of micro cars on expressways can be increased by improving the visibility of micro car.

전(全)세계적으로 초소형전기차에 대한 관심이 증가하고 있는 추세로, 국내에서도 초소형전기차에 대한 정책적 지원이 확대되고 있다. 그러나 국내 법제적 제한사항으로 인한 초소형전기차의 안전성 저하 및 주행 가능 범위의 제한으로, 초소형전기차의 자동차전용도로 운행을 위한 최소 안전기준 충족이 필요한 실정이다. 본 연구에서는 운전자 반응시간 저하 방지를 위한 초소형전기차 안전식별등 시인성 실험을 실시하였다. 초소형전기차의 차량 후방부에 안전식별등을 설치하였으며, 시인성 및 불쾌눈부심 평가를 통해 초소형전기차의 자동차전용도로 주행가능 여부를 파악하였다. 그 결과, 입체교차시설의 가속차로 지점 합류 시 초소형전기차 안전식별등 설치효과가 나타났으며, 안전식별등의 점등/소등 기능 적용과 관련하여 자동차전용도로 진입 시 점등 방안, 일반도로 주행 중 소등 방안이 효과적일 수 있음을 확인하였다. 본 연구에서 제시한 초소형전기차 운영방안을 적용할 경우 초소형전기차의 시인성을 증진시켜 초소형전기차가 자동차전용도로를 주행하는데 필요한 차량의 안전성을 증가시킬 수 있을 것으로 판단된다.
