Because the cost of road management is increasing proportional to road construction, there are needs to build general and systematic road management system. To solving such problems, Ministry of Construction and Transportation started research and development of Highway Management System(HMS), and established a foundation for systematic road management system. But, the implementation of HMS has some limitations because it is just converting roads of physical space to roads of electronic space and managing roads of electronic space. Although HMS offers many conveniences compared to old system which was based hard-copy and paper maps or unit operations, it can not overcome the problem of inefficency of road management due to the separation of operation between outer field and inner office. Therefore, to overcome such inefficency, this study focused on Road Disaster Management System development based on Ubiquotous.

After insufficient road facilities are expanded, it is more important to maintain performance of road facilities the time according to passing. When the road facilities are maintained optimally through proper maintenance, the total amount of investment can be minimized and national competitiveness is improved. Individual maintenance research of road facilities such as PMS or BMS was in progress until currently, but it is difficult to joint ownership and share information between systems, and it is impossible to use as the decision-making. Therefore, Asset Management System for road facilities is enforced to solve the inefficiency of existing systems, maintenance the road facilities systematically under the limited budget and get the maximum benefits against the cost from the view point of long-term. In this paper, the concept of Asset Management System explained, and research plan from KICT in order to introduce the Asset Management System of road facilities from 2008 hereafter for 5 years accounted.

It is difficult for the road management system to give a correct road information because road facilities are differently managed according to each object. In this study, we have solved this problem of road information management and, developed a system which is able to integrate various data of facilities and to maintain the latest property of data by introducing server-client network structure for managing road facilities more efficiently. And, we have shown the affairs of the road information management could be achieved scientifically, by the integration of graphic, attribute and photograph information relevant to road. This enabled the connection of graphic data and the stereo drawing composition, and enhanced the feeling of real world experience using the dynamic image data of the road.

This study aims to construct a management system of road position information as part of the build-up to a maintenance and management system of highways. First, information on the positions of the roads were obtained by a real-time kinematic satellite surveying, and then the degree of accuracy was analyzed in comparison with the data of the existing design drawings. The linear coordinates of road center line obtained by using RTK GPS showed about 7.6-13.2cm errors in X and Y directions in the case of the national road No.2 section, and about 8.4-9.2cm errors in the case of local road No.1045 section. These errors were within the tolerance scope regulated by the TS survey, and could be practically used. In the case of vertical alignment, there were about 6.2cm errors in the Z direction in local road No.1045 section. Aerial photographs are normally used in producing numerical maps, and it can be practically used because the tolerance scope of the elevation control point is l0cm when the scale of aerial photographs is 1/1000. The management system of road position information, utilizing Object-Oriented Programming(OOP), was built having the data acquired in this way as the attribute data. The system developed in this way can enable us to spot the positions of road facilities, the target of management with ease, to easily update the data in case of changes in the positions of roads and road facilities, and to manage the positions of roads and road facilities more effectively.

Road sign is one of the road attached facilities to provide conveniences to motor drivers. The setup of location information according to the related regulation and the inclusion of various attributes such as place names, route numbers, symbols, bearings, distances to the place of interest distinguish the road sign from other facilities. These features give advantages to the informationization of road sign. Presently there established about 130,000 road signs on each class of roads, and about 280 road management offices have controlled these road signs independently, but there are plethora of ineffectiveness such as the lack of consistency, recognition, connectivity, and location suitability etc. These are the major factor of confusions rather than providing conveniences, and arisen a lot of public grievances. Accordingly, in this research the road signs throughout the nation were databased and the web-GIS based road sign management system was established to ameliorate the problems reveled. Since the road sign management system we developed reflected the demands of the persons in charge and users, the management effectiveness might be enhanced and the public inconveniences will be reduced.
