 Abstract
Since 1970 transportation investment has been made rapidly, however the doubt on duplication and overinvestment of transportation facility also has been brought up. Thus the necessity for reasonable estimation of investment scale increases. In this paper various researches related to this subject are reviewed and categorized according to their methodologies, namely, the methodology using international comparison, trend of investment policy and endogenous economy development model. Based on these methodologies, AHP is applied to calculate proper investment scale. The result shows that the budget for satisfying the investment scale is estimated about 19.51~24.49 trillion won. This value is 4.28~9.26 trillion won higher than the proper investment budget established in National Fiscal Management Plan. In the future, it is necessary to establish systematic and efficient transportation investment plan by developing transportation policy model which can assess the economic feasibility, social equity and environmental soundness etc. at the same time.
