In urban planning, road facility is used not only for the transportation purpose but also for the utility line space purpose such as electrical, gas, tele communication, heating, water, sewer, and so on. However, since these utilities are built by many different groups, it becomes very difficult to communicate each other. Delay in one party can cause another party's schedule delay but they don't commuicate often. Also, some delay in utility work can cause frequent pavement cut. And, this will impact on construction cost, schedule delay, low quality, user complain and cost. This study developed spatiotemporal decision model to prevent prequent utility cut for mega project such as new urban development project. In addition, this study developed utility cut management system to manage utility cut schedule under pavement. Finally, developed system was applied to new urban development project and verified there effectiveness.

Since IFC (Industry Foundation Classes) 4 is based on the representation of 3D elements for an architecture project, and does not define standardized shapes for civil projects such as roads, bridges, and tunnels etc, it has limitations in securing interoperability for exchanging a shape information model for the civil projects. Besides, since road facilities have a linear reference, which is modeled along the center alignment, it is difficult the designers to create a standardized 3D road model. The aim of this study is to configure structure elements and their attribute for a road in the perspective of 3D design for developing a shape information model for the road. To solve these issues, this study analyzes the design documents, which consist of a road design handbook, guide, specifications and standards, and then extract shape elements and their attributes of road structures. Such shape elements are defined as an entity item and we review a hierarchical structure of a road shape defined by a virtual road model. The detailed elements and their attributes can be utilized as a 3D shape information model for constructing BIM (Building Information Modeling) environment for Infrastructures. Besides, it is expected that the suggested items will be utilized as a base data for extending to IFC for a road subdividing the detailed shapes, types and attributes for road projects.

Traffic accidents at night occur more than any other time because of improper road light facility and delineators. Therefore, cost-effective criteria of installing delineators are needed instead of expensive road light facility, especially, on rural road including light volume of traffic. This paper presents the criteria of installing 'Chevron Alignment Sign' considering driver's visual behavior characteristics and 'Raised Pavement Marker' considering critical encroachment angie of both straight section and curve one in order to reduce both the number of accidents on curve sections and the number of road encroachment accidents, respectively. The characteristics of visual behaviors can be expressed by visual angle involving curve radius and intersection angle. The estimated installing angles are $1^{\circ}{\sim}2.5^{\circ}$ by radii, which is based on changes in sensitivity across visual field by exogenous attention. Also, the raised pavement marker is installed every 2m, 3m, and 4m considering critical encroachment angles by radii.

미국, 영국, 호주, 뉴질랜드 등 나라들은 최소의 비용으로 도로시설의 기능을 유지하기 위해 사회기반 시설의 유지관리에 자산관리체계를 도입하고 있다. 자산관리체계를 도입하기 위해서는 기존의 사후 대응적 (fix-on-failure) 유지관리 방식에서 사전 예방적(preventive) 방식으로 전환이 필요하다. 본 연구는 해외에서 활용되고 있는 자산관리용 소프트웨어의 특성을 분석하여 사전 예방적의 유지 관리하기 위해 필요한 자산관리시스템 개발 방안을 제시하였다.

A road is an infrastructure that helps boost up growth of local economy, connections among local communities and living conditions. For South Korea the increase in infrastructures like roads now concentrates on specific regions, which causes regional imbalance. also, some areas are faced with the overall weakness of local economy such as decrease in local tax revenues, slowdown in industrial and economic growth of regions, and the low independence of local finances because lack of roads, a basis of local economic growth, make big and smaller business reluctant to invest in localities. In addition, even though the power-centralized age turns to a decentralized age, the preference of development policies by the existing economic size rather than those of nationwide balanced development gets the economic gap of localities deeply-rooted; moreover, disparity of local wealth has a tendency to even differentiate the overall quality of living. The paper intends to analyze relations between road development and local economy focused on road construction, one of requisites to balance national development and accelerate local economy.
