Abstract

This study was conducted to evaluate the characteristics of installation dimensions of speed control humps based on the theoretical dynamic analyses. The field surveys of speed control humps were performed first to compare their sizes with those suggested in the installation standard. Then, the displacement response spectra under impact loads were obtained using the single degree of freedom models where the vehicle and human were assumed to combine completely. The analysis results showed that the human perception became larger as the width and height of the humps increased, but the extremely higher uncomfortableness should be avoided. In addition, the ratio between the width and height should be considered when the humps are designed and installed because the ratio governs the vertical acceleration magnitude.

본 연구는 과속방지턱의 설치규격 특성을 검토하기 위하여 동역학적 이론을 기반으로 분석을 수행하였다. 먼저 과속방지턱에 대한 현장조사를 통해 기하구조 자료를 수집하여 현행 설치기준과 비교 분석하였으며, 차량과 운전자를 일체화시킨 단자유도 모델링 방법을 이용하여 충격하중에 의한 변위응답 스펙트럼을 구하였다. 해석 결과 과속방지턱의 폭과 높이는 커질수록 운전자에게 미치는 심리적 부담감이 커지나 과도한 불편함을 초래하지 않도록 크기를 결정해야 하는 것으로 분석되었다. 또한 과속방지턱의 폭과 높이의 비율은 운전자가 느끼는 수직가속도의 크기를 지배하므로 폭과 높이의 조화도 고려하여 과속방지턱을 설치하여야 한다.
