Abstract

Road infrastructure has increased explosively due to economic development after industrialization and at present road infrastructure is being changed and increased by construction of new roads and maintenance and expansion of existing roads. Such road infrastructure should support safe driving. Road management plays an important role in safe driving. The purpose of this dissertation is to verify predictability of dangerous sections by analyzing road geometrical structure such as surface irregularity and superelevation for some sections in Central Inland Expressway by MMS and present ways of managing roads using MMS. Having analyzed surface irregularity of roads by using MMS, it was found that over 50 percent of all eight sections, targets of this study need betterments and for superelevation, over 50 percent of two sections goes against superelevation standard. Targets of this study are sections that accidents occurred frequently based on history of past accidents and predictability of dangerous sections can be verified through analysis of road geometrical structure using MMS. Using MMS data created by construction of high definition maps which are being undergone for all roads and methods proposed by this study will help investigate dangerous sections efficiently according to road environment. A result of MMS can be used for maintenance of road furniture.

우리나라는 산업화 이후 경제발전으로 도로 인프라가 폭발적으로 증가하였고, 현재도 신설도로 구축과 기존도로의 보수와 확장 등으로 도로 인프라의 변화와 양적인 확대가 진행되고 있다. 이러한 도로 인프라는 차량의 안전 운전을 뒷받침하여야 하며, 도로 관리는 안전 운전의 중요한 역할을 담당하고 있다. 본 논문은 중부내륙고속도로의 사고위험 구간에 대한 평탄성과 편경사를 MMS로 분석하여 MMS를 이용한 도로 기하구조의 분석 가능성을 확인하는 것이다. MMS를 이용한 도로 평탄성을 분석한 결과 연구 대상지 총 8개 구간에서 50%를 넘는 도로가 개량공사가 필요한 것으로 분석되었으며, 편경사의 경우 2개의 구간에서 편경사 기준을 50%이상 벗어난 것으로 나타났다. 이를 통하여 MMS를 이용한 도로기하구조 분석이 가능함을 확인 할 수 있었다. 향후, 모든 도로를 대상으로 진행 중인 정밀도로지도 구축에서 생성된 MMS 데이터와 본 연구에서 제안한 방법을 이용하면 도로기하구조에 따른 사고위험 구간을 효율적으로 조사할 수 있으며, 도로시설물의 유지관리에도 MMS 결과를 활용할 수 있을 것으로 판단된다.
