초록

9호선은 2019년 전체열차를 6량화하며 혼잡완화를 위해 노력하였으나 혼잡을 완전히 해소하기에는 역부족인 상황이다. 또한추가적인 열차 증편은 막대한 예산이 필요하기 때문에 세금의 지원 또는 요금의 인상이 불가피하다. 이에 본 연구에서는 서울 지하철 9호선을 대상으로 혼잡완화에 대한 추가지불용의액을 추정하고, 이를 기반으로 현재 6량 열차로 운행 중인 9호선이 8량화운행을 할 때의 편익을 분석하고자 한다.

영어초록

As of 2020, Seoul has urban railroads on Lines 1 to 9, except for the light rail lines. Lines 1 to 8, which are managed by the Seoul Metro, have 8- to 10-car trains, while line 9 is operated with 6-car trains. Owing to this limited capacity, there is severe congestion on Line 9 during peak hours. Therefore, this study analyzes the benefit of operating Line 9 with 8-car trains to evaluate the effects of a new strategy. The willingness to pay (WTP) factor was investigated using the contingent valuation method (CVM) in accordance with the scenario of mitigating congestion inside the train. From the study, additional payment amounts of 7.3–114.3 won were estimated based on the congestion phase-reduction scenario. When Line 9 is operated with 8-car trains, considering the number of passengers using Line 9, the benefits amount to about 2.37 billion won as of 2019 and about 3.01 billion won as of 2030. This study is a pilot attempt to apply a national guideline, and the results are expected to be provide useful data for establishing an operation strategy for the Seoul Subway Line 9.
