Abstract

Seoul Metropolitan Urban Railroad has an undecided route that does not estimate the passenger transportation route. For this reason, the fare of the urban railroad is calculated by the assumption that passengers pass through the minimum distance. Therefore, if a transfer station on the urban railroad is added, the trip shortest distance could be decreased and the fare also reduced. In this study, this phenomenon defines the fare paradox(Shin, 2022) and estimates the impact of the fare paradox by opening the GTX-A. For this purpose, a scenario before and after the opening of the GTX-A has been established, and an additional fare has been estimated by proportional planning of the Seoul Metropolitan Integrated Distance Based Fare Policy. Fare Paradox was analyzed to about 0.024 % of daily income. It is expected to be used as a plan to determine a rate policy, such as the establishment of a GTX-A, B, C, D, and a light rail line.

수도권 도시철도는 승객의 통행경로를 추정하지 못하는 경로미확정 이슈가 존재한다. 이 때문에 도시철도 요금은 승객이 최소이동거리를 통행한다는 가정으로 계산된다. 따라서 도시철도의 환승역이 추가되면 최소이동거리가 줄고 요금수입이 줄어드는 구간이 나타난다. 본 연구는 이러한 현상을 요금 Paradox(Shin, 2022)로 규정하고 GTX-A 개통에 의한 요금 Paradox 영향을 추정하였다. 이를 위해 GTX-A의 개통 전후의 시나리오를 구축하여 수도권 통합거리비례요금제에 의한 추가요금의 감소분을 추정하였다. 요금 Paradox는 일일 수입금의 약 0.024%에 해당되는 것으로 분석되었다. 향후 GTX-A, B, C, D 및 경전철 노선 신설 등의 요금정책 의사결정 툴로서 활용될 것으로 기대된다.
