Abstract

This study quantitatively derived the direct socio-economic effects of the Gyeongbu Expressway, which opened in 1970, and suggested a methodological approach for more reliable results. The scenario was set when the Gyeongbu Expressway was not constructed in 1970, the opening of the Gyeongbu Expressway was delayed by 10 years, and the toll road between Seoul and Daejeon, or between Seoul and Gangneung was opened instead of the Gyeongbu Expressway as suggested by the World Bank. In addition, direct benefits were estimated by calculating and comparing the current vehicle operating costs, travel time costs, traffic accident costs, and environmental pollution costs. As a result, it was estimated that about 351 trillion won in direct benefits occurred, and it can be seen that the promotion of the construction project of the Gyeongbu Expressway at that time had a huge impact on South Korea's social economy.

경부고속도로는 서울과 부산을 연결하는 국토대동맥으로써 여객과 화물수송의 역할 뿐 만아니라 산업과 도시발전에 영향을 주었다. 본 연구는 1970년 개통한 경부고속도로가 사회경제적으로 미친 직접적인 효과를 정량적으로 도출하였으며, 보다 신뢰성 있는 결과도출을 위하여 과거 시점의 네트워크 구축 및 O/D교통량추정, 편익계수의 보정방법론을 제시하였다. 1970년 당시 경부고속도로가 미건설된 경우, 경부고속도로 개통이 10년 지연된 경우, 세계은행의 제안과 같이 경부고속도로 대신 서울~대전, 또는 서울~강릉 간 유료도로가 개통되는 경우의 시나리오를 설정하였으며, 각 시나리오와 현재의 차량운행비용, 통행시간비용, 교통사고비용, 환경오염비용을 산정·비교하여 직접편익을 추정하였다. 분석 결과를 통해 1970년 경부고속도로 개통은 10년 지연되었을 때와 비교하여 약 351조의 직접편익이 발생하는 것으로 추정되었으며, 이는 당시 경부고속도로 건설사업 추진이 우리나라 사회경제에 막대한 영향을 주었다는 것을 알 수 있다.
