Abstract

The rate of traffic accidents that occurred in Korea last year is 10 out of every 100,000 people, ranking it 6th among the 35 OECD member countries. The accident rate of children with disabilities and elderly people is also high. The purpose of this study is to introduce traffic safety facilities which have been developed for the reduction of traffic accidents in non-urban areas in Korea through an analysis of the related literature, the accident factors using traffic accident analysis system data and traffic accident characteristics. Traffic safety integrated facilities for ICT-based pedestrian crossings are subject to cross-sectional coverage of child protection zones. The smart safety fence prevents vehicles from parking illegally and informs pedestrians that there is an access vehicle on the pedestrian crossing. The smart bump is designed to warn drivers who are not aware of the pedestrians. In order to standardize the appropriate form and size of the traffic safety facilities for pedestrian crossings, we constructed a standard model for each type, considering the road function, press classification, power, lane number, geometric form, etc. As a result, the rate of traffic accidents involving vulnerable people was reduced. In addition, it is anticipated that the maintenance costs will be reduced by the use of a solar power supply and their compatibility with the existing installed safety fences.

지난해 국내에서 발생한 교통사고 사망자 수는 OECD 회원국 가운데 인구 10만명당 10명으로 35개국 중 6위를 기록하고 있고, 어린이나 노인과 같은 교통약자의 사고율도 높은 수준에 있다. 본 연구에서는 관련 문헌 검토, 교통사고분석시스템 자료를 이용한 사고요인분석 및 교통사고 특성 분석 등을 통하여 국내 비도심 지역 교통약자의 교통사고 저감을 위해 개발하고 있는 교통안전시설물을 소개하고자 한다. ICT기반 횡단보도용 교통안전 통합시설물은 어린이보호구역의 횡단보도를 우선 검토대상으로 하여 불법주차 차량을 배제하며, 보행자에게 횡단보도에 접근 차량이 있음을 알려주는 스마트 안전 휀스와 횡단보도 보행자가 있음을 인지하지 못한 운전자에게 경고하는 스마트 방지턱으로 구성하여 상호 작동하도록 설계하였다. 횡단보도용 교통안전시설물의 적정 형태 및 규모를 표준화하기 위하여 도로 기능, 보도 구분, 전력, 차로 수, 기학적 형태 등을 고려한 타입별 표준모델을 구축하였고, 시설물의 요구 기능을 정의하여 아이디어를 구체화하였다. 이에 따라, 교통약자의 교통사고를 저감하고, 태양광 전력공급, 기존 설치된 안전 휀스와의 호환성을 염두에 둔 디자인으로 유지관리비용 절감효과를 얻을 수 있을 것으로 기대한다.
