Abstract

The VE/LCC study on the existing multi-utility tunnel examined the economical feasibility of the collective area through the cost-benefit analysis of the ten major routes of Seoul for the benefit (7 items) and the cost (5 items) through quantitative methods. In this paper, we analyzed the economic efficiency of 61 sectors by adding 3 items (reduced traffic accident, reduced vehicle noise, social-economic loss). The reduced traffic accident item is an improvement of the traffic accident cost that can be saved by the implementation of the project, and the reduced vehicle noise item is an indicator of the amount of noise change caused by the implement of the business. Finally, the social-economic loss items represent the impact on the local economy due to the construction of the multi-utility tunnel. The amounts of the additional items were compared and items added in the open type and tunnel type multi-utility tunnel were analyzed for each analysis. Result on the analysis, it analyzed the items applied to the basic and detail models in the economic evaluation of the multi-utility tunnel design, and makes it possible to evaluate the economic efficiency more efficiently. The economic evaluation of the basic and detailed models including the items presented in this study will be often used in the design of the multi-utility tunnel design.

기존 공동구에 관한 VE/LCC 연구는 정량적 방법을 통하여 편익(7개 항목), 비용(5개 항목)에 대하여 서울시의 주요 10개노선을 대상으로 비용-편익 분석을 통한 공동구의 경제적 타당성을 검토하였다. 기존 공동구에 관한 VE/LCC 연구는 정량적 방법을 통하여 편익(7개 항목), 비용(5개 항목)에 대하여 분석을 수행하였다. 이에 본 논문에서는 3개의 항목(교통사고감소, 차량소음저감, 사회 경제 손실)을 추가하여 서울시 주간선도로 61개 구간에 대하여 경제성 평가를 분석 하였다. 교통사고감소 항목은 사업시행으로 절감할 수 있는 교통사고 비용을 개량화한 것이며, 차량소음저감 항목은 사업시행으로 발생하는 소음 변화량을 나타낸 지표이다. 마지막으로 사회 경제손실 항목은 공동구의 시공으로 인하여 지역경제에 미치는 영향을 금액으로 나타낸 것이다. 편익은 10개의 항목, 비용은 8개의 항목들 중 우선 추가 항목들의 금액을 비교 분석 하였으며, 개착식 및 터널식 공동구에서 추가된 항목들과 전체 항목들이 각 분석에 미치는 영향 정도를 분석하였다. 분석의 결과로 공동구 경제성 평가시 기초 및 상세 모델에 적용되는 항목들을 분석하여 공동구 설계시 보다 효율적인 경제성 평가가 가능하도록 하였다. 본 연구에서 추가로 제시된 항목들을 포함한 기초 및 상세 모델의 경제성 평가는 공동구 설계시 자주 활용될 것으로 판단된다.
