PURPOSES : This study is to improve the highway management and rehabilitation efficiently by method for asset management. METHODS : Based on the literature review, The concept of this paper is to investigate the use of asset values from a Bridge management system to improvement of maintenance system more efficiently. This study is suggested for an evaluation method based on the current bridge condition by Written-down replacement cost of the assets. RESULTS : We suggests the optimization methodology of road asset valuation for budge distribution and performance measure. CONCLUSIONS : We evaluate all of national highway's bridge by the optimization methodology of road asset valuation, and suggest application methods of asset result.

PURPOSES : This study proposes the road asset valuation approach using alternative depreciation methods. It has become necessary to have asset management system according to the adoption of accrual basis accounting for governmental financial reporting and the amendment of the road act. Therefore, it is very important to analyze the effect of depreciation methods on road asset value as a basic research for road asset management system. METHODS : The Ministry of Strategy and Finance (MOSF) has mainly performed road asset valuation based on Write down Replacement Cost and Straight Line depreciation method. This study suggests some appropriate asset valuation methods for road assets through case analysis using three depreciation methods: Consumption-based depreciation method, Condition-based depreciation method, and Straight Line depreciation method. A road asset valuation data of national highway route 1 (year 2014) is used to analyze the effect of three depreciation methods on the road asset value. Road assets include land and structures (pavement, bridge, and tunnel). This study mainly focuses on structures such as bridges and tunnels, because according to governmental accounting standards, land and road pavement assets do not depreciate. RESULTS : The main results of this study are as follows. Firstly, overall asset value of national highway route 1 was estimated at 6.97 trillion KRW when MOSF's method (straight-line depreciation method) is applied. Secondly, asset value was estimated at 4.85 trillion KRW on application of consumption-based depreciation method. Thirdly, asset value was estimated at 4.37 trillion KRW when condition-based depreciation method is applied. Therefore, either consumption-based or condition-based depreciation methods would be more appropriate than straight-line depreciation method if we can use the condition data of road assets including land that are available in real time. CONCLUSIONS : Since road assets such as pavements, bridges, and tunnels have various patterns of deterioration and condition monitoring period, it is necessary to consider a specific valuation method according to the condition of each road asset. Firstly, even though road pavements do not depreciate, asset valuation through condition-based depreciation method would be more appropriate when requirements for application of non-depreciation approach are not satisfied. Since bridge and tunnel facilities show various patterns of deterioration and condition monitoring period by type and condition level, consumption-based depreciation method based on deterioration model would be appropriate. Therefore, it is necessary to have a reasonable asset management system to apply condition-based depreciation method and a periodic condition investigation to manage road assets well.

도로시설물은 국가 경제 활동의 기반을 형성하는 기초적인 시설물이며 국가에 필수적인 기반 시설물이다. 현재 국내 관리대상 도로시설물은 해마다 증가하고 있으며, 이에 따른 유지관리비 예산의 상승이 예상된다. 이와 같이 건설되어 축적된 도로시설물에 대한 비용 효율적 관리를 위해서는 자산이 지닌 가치를 객관적으로 나타낼 수 있는 지표가 필요할 것이다. 이러한 지표는 자산가치로써 화폐단위로 나타낼 수 있다. 국외에서는 자산관리 및 자산가치평가에 대한 연구가 활발히 진행되고 실제 공용중인 도로시설물에 적용을 하고 있지만 국내에서는 이에 대한 준비나 연구가 부족한 상황이다. 본 논문은 도로시설물의 자산관리를 위한 합리적인 자산가치평가를 도출하기 위한 방법으로 자산가치평가방법을 기존의 문헌과 연구 자료를 통하여 조사 및 정리를 하였다. 이를 바탕으로 도로시설물에 자산가치평가방법들을 적용하기 위하여 국내 실정과 특성이 반영된 자산가치 프로세스를 개발하였다. 개발된 자산가치 프로세스에 따라 실제 공용중인 도로시설물을 적용하고 그 결과를 분석하여 각 자산가치평가방법들의 활용방안을 도출하였다. 또한, 가장 활용성이 높은WDRC(Written Down Replacement Cost)방법을 이용하여 자산관리업무 수행 절차를 위한 자산 관리 업무지원 모식도를 제시하였다.
