In this paper, we propose a system to detect various damage automatically inflicted on road pavement by collecting and analyzing data from acceleration and camera sensors in real time. The proposed system sends the collected images, acceleration signals, and GPS coordinates to the road manager and the database in the remote server, shortly after detecting the damage to the road pavement. Our study makes three key contributions. The proposed system 1) enables road managers to maintain road conditions quickly, accurately, and conveniently; 2) allows road mangers to take care of various kinds of damage to the road pavement at the initial stage; and finally 3) even makes it possible to track the damage, which suggests that the integration of a high-level decision support function becomes affordable. We tested the sensitivity and precision of the proposed system against real-time data obtained from the vehicles driving on the highway at an average speed of 100 km/h. With ten iterations, the proposed system achieved an average sensitivity of 74% and an average precision of 84% in road pavement damage detection, which is comparable with the best competing schemes.

In this study, developed economic and efficient Pavement Management System (PMS) that can produce suitable M/R method through estimation and analysis of pavement condition exactly, to overcome past unscientific pavement management limitations. First on the basis of data of the inside and outside of the country on PMS and pavement condition data of Seoul metropolitan, composed logical algorithm such as pavement condition investigation and analysis, detailed eye investigation whole system estimation etc, and it verified that this algorithm is suitable system through the inside and outside of the county PMS research examples and results of detailed eye investigation. Also, Considering user interface, developed PMS program and GIS program with such logical algorithm.

In this study, the damages and condition of road pavement were analyzed using pavement management system (PMS) for the structural improvement. Problems of road pavement management were issued by in-depth interview with workers in charge of plant, construction and supervision. By surveying advanced road pavement management, the way how to improve road pavement management in Seoul was discussed. In conclusion, it is necessary to take measures against road heavy traffic and heavy rain in summer. It was found that the problem of early damages of road pavement due to uniform layout with analyzing life cycle cost (LCC). According to the results of survey, it was suggested to strength practical training and to control precisely the temperature of pavement in the process of production and construction.

In this paper, a PMS(Pavement Management System) is presented for the public agency who wish to execute rational repair by referring to asset management information regarding road pavement. The aim of the paper is to provide the decision makers with the planning information regarding maintenance strategies for efficient road pavement management. We found that life cycle cost can be minimized and repair cost in each year fluctuates when repeating repair at the IRI management level. The validity of PMS application presented in this paper is investigated through case studies for conducted for 22 national highway road sections in Korea.

National highway is one of the social infrastructures that continue to be managed in order to serve their full functions. The national highway has been managed by the Pavement Management System (PMS) until now. The PMS manages the highway as a way of facility maintenance and maximizes the service life of the highway with minimum cost. The cost is evaluated mainly with a facility manager's perspective based on engineering judgment. People's needs of quality of life have been increased as their income level is rising and naturally the opinion of citizen as a taxpayer plays an important role in determining national policy. Therefore, the contentment of a user's perspective was the starting point of addressing these needs. The Level of Service began to be used as a measure for the evaluation of the user's perspective. In this thesis we would like to design an application and a data architecture for a pavement asset management system and to show how it meets the requirements of KTAM-40 Systems.

본 연구의 목적은 도시 지역에서 지진 발생시 중요한 대피로 역할을 하는 도로의 위험평가요소를 분석하고 데이터베이스(Database, DB)를 구축하는데 있다. 현재 우리나라는 도로의 체계적인 유지관리를 위해 도로관리통합시스템이 개발되어 있으나, 이는 도로대장전산화, 포장관리시스템, 교랑관리시스템, 도로절개면유지관리시스템 등에 한정되어 있다. 다시 말해서 재난 시 사람들이 신변의 안전을 확보할 수 있는 대피나 구급을 위한 통로로써의 도로에 대한 이해가 부족한 실정이다. 따라서 본 연구에서는 선행연구의 분석을 토대로 방재관점의 도로관리를 위한 항목들을 자연환경, 시회환경, 도로 및 시설물, 유발요인 등으로 제안하고, 서울대학교 부근을 대상지역으로 하여 이들 요인을 DB화하였다. 이는 도로와 주변 환경 등을 동시에 고려하여 재난 발생 시 대피와 구조 활동을 위한 방재계획은 물론, 지역별 위험도평가 및 재해위험도작성에 기초 자료로 이용될 것으로 기대된다. 그러나 본 연구에서는 기구축된 GIS 자료가 아닌 현장 조사를 바탕으로 구축된 DB로, 방재관점의 통합된 DB의 필요성을 제시하는데 그 의미가 있을 것이다.

This study aims at establishing the decision-making support system for the highway assets, long-term performance presumption and evaluation of asset value, which are appropriate for Korea, and proposing the methods of the optimal engineering method and the timing decision for the preventive maintenance through the project evaluation, the optimization method and life-cycle analysis related to the highways. In order to supplement the current problem of the near-sighted budget management system, which chooses the maintenance place of the highway, depending on the level of the budget with fixed amount, the long-term required budget prediction system and the economy principle were introduced, so that the pavement agency can predict the level of the required budget, and it was aimed to develop the pavement asset evaluation system to maintain the performance of the highway with the minimum of the cost. In the use of the highway pavement asset evaluation system, to maintain the appropriate level of the pavement evaluation index, when the budget was efficiently established in the reference of the required maintenance budget for the chosen section of the highway in the year concerned, it was possible to analyze the most rational pavement maintenance budget. With this result, it is estimated to prevent the unnecessary waste of budget in advance, and through the development of the decision-making system for the long-term performance presumption and the asset value estimation of the pavement, it is expected to able to analyze the previous evaluation of the project related to the highway and the feasibility of introduction.
