We analyze the efficiency of congestion pricings and transit subsidies in the spatial micro-economic model based on a general equilibrium environment. In this setting, we decompose the total welfare change into component factors and identify the reason of the change in the efficiency caused by policy instruments; these component factors are divided into indirect factors and direct factors including of origin-destination and mode choices. We set up the model as adding mode choice to the standard format in the fashion of Anas and Kim (1996) and extend the methodology proposed by Yu and Rhee (2011) and Rhee (2012) for deriving theoretical and analytical solution. Most of welfare gain comes from the modal shift from car to bus. The relative efficiency of subsidies in relation to the first-best pricing is lower than it of congestion pricings although the change in bus share by subsidies is similar to it by congestion pricing. Subsidies give rise to more modal shift from a car to a bus for long-distance commuting than it caused by congestion pricings. As the increase of bus share for long-distance commuting leads to the increase of cross-commuters passing through CBD, the welfare gain by subsidies is lower than it by congestion pricings.

현재 전국 지자체 중 53곳에서 복지택시 제도를 시행하고 있다. 하지만 제도가 시행된 지 오래되지 않아 체계적으로 시스템화 되지 않고 시행되고 있어 담당자들의 업무상의 불편을 초래하고 있다. 본 논문에서는 이와 같은 문제를 해결하기 위해 복지택시의 효율적인 운영을 위한 보조금 정산 시스템을 설계하고 구현한다. 이를 위해 청주시 대중교통과의 협조를 얻어 청주시 복지택시 업무 전반에 걸쳐 세밀히 파악하였으며, 택시기사의 보조금신청과 관련된 불편사항과 담당공무원의 정산관련 업무의 불편사항 및 개선사항을 도출할 수 있었다. 또한, 보조금 정산시스템 구현에 대하여 담당자들의 설문 조사를 통해 업무의 효율성을 입증하였다.

As one of the most traffic devices, bus has played a great role in Korea for the last years. However, a great many peoples in big cities have continually decreased with the increase of private car ownership. It causes lower quality of bus service and unstability of operation in many bus companies. In the several local government, the operation system of bus was changed to Bus Quasi-Public Operating System. The aim of this study is to assess the effects and to suggest improvement strategies of Bus QPOS. According to the results of the analysis, Bus QPOS has brought various positive effects, but it has occurred negative effects, especially a much increase of government subsidies to bus company. To resolve a negative effects, government should examine the whole condition of bus operations. This study suggests strategies to improve Bus QPOS, which is including transparency of management, fair assessment system, standard cost system for bus operations.

환경부에서는 1990년대 말경 대기오염 문제를 해결하기 위한 방안으로서 디젤 버스를 CNG 버스로 대체하고자 CNG 탱크 추가 등으로 가격이 비싼 CNG 버스에 대하여 보조금을 지급하고 CNG 충전 인프라를 구축하는 등의 지원정책을 실시하여, 현재 국내에서 운행하는 버스는 일부 소도시를 제외하면 대부분 CNG 버스로 대체되었다. 이러한 CNG 버스 정책으로 인하여 당시만 해도 매연 배출이 심하던 디젤 버스로 인한 공해물질이 줄어들고 대기질이 어느 정도 개선된 효과를 거두었다. 최근들어 환경에 대한 중요 이슈의 개념이 변화하고 있으며 자동차 기술도 새로운 변모를 보여주고 있는 것이 현실이기 때문에 CNG 버스만으로 운영되는 정책이 향후에도 계속 유지가 되어야 할지 다시 한번 생각해보아야 할 필요가 있다.

현재 FTA 가 큰 이슈로 대두되고 있다. 이러한 세계적 추세는 가까운 장래에 한,중,일 연안 여객선 시장 개방에도 영향을 미칠 것이다. 따라서 비슷한 상황에 있었던 스코틀랜드 연안 여객선 운영과 EU의 관계를 살펴보고 성공 사례를 벤치마킹하고자 한다. 연안 여객선을 대중 교통화 시킴으로 섬의 접근성을 개선하여, 섬 주민들에게는 편리성을 제공하고 관광객도 유치하려는 공동의 목적을 달성하는 데에도 한국 연안 여객선 운영에 개선은 필수적이기 때문이다.

Advertising on the exterior of buses was initiated in 1985 with the aim of generating operational funds for the 1988 Seoul Olympics. However, despite numerous technological advancements, the regulations governing the method (sheet attachment), area, and placement of exterior advertising on buses have remained unchanged to date. This has constrained the potential for profitability and efficiency in bus exterior advertising. According to Seoul Metropolitan Government, metro usage increased by 23 % in 2019 (prior to the COVID-19) compared to 2006, while bus usage decreased by 10 %. Consequently, financial subsidy for buses surged significantly over the past five years (2018-2022), averaging around KRW 450 billion, which is approximately 1.27 times the average for the preceding decade (2013-2022). The majority of revenue for bus transportation agencies is derived from passenger fares (81.1 %) and subsidies from Seoul City (17.5 %). Hence, it is imperative to enhance the share of revenue from sources other than fares. This study proposes an expansion of the role of bus exterior advertising by increasing the advertising area as a means to increase non-fare revenue. Two alternatives were proposed to expand the advertising area by 17 % and 94 %, respectively, compared to the current level, and their potential impacts were analyzed. The findings indicate that advertising revenue could increase from a minimum of KRW 3.2 billion to a maximum of KRW 53.9 billion, and public subsidies could be reduced by as much as 11.9 %. The bus exterior advertising can serve as an effective approach to diversify transportation revenue and decrease public subsidies.

The recent increase of light rail construction by the private sector in Korea has caused a new issue in forecasting rail demand. Integrated fare systems between several rail operators is convenient and brings cost savings to users, and therefore is also very effective in increasing demand. However, it causes some short-term revenue loss to operators so that the private sector often suggests a non-integrated fare system. The current rail demand forecasting model is based upon an integrated fare system. Thus this model cannot be used to forecast the demand with a non-integrated fare system. Some value of transfer fare should be estimated and applied to forecast the demand in a non-integrated fare system. This study conducted a stated preference (SP) survey on urban railway passengers and estimated the value of transfer fare. The estimated value is 2,609 Won/hr, which is about 52% of in-vehicle time. This shows railway users have a tendency to pay more for transfer fares to save time or distance. This value has some limitations since it is derived from the SP survey. If some non-integrated fare system is applied in the future and a RP survey is conducted and compared with these study results, a more clear value of the transfer fare will be derived.
