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.

Securing publicness and efficiencies are the two core goals for implementing quasi-public bus system. However, researches for evaluating the quasi-public bus system with respect to the two goals have been very limited. This study represents an attempt to evaluate the system performance in these two aspects. To achieve this, a framework for performance evaluation is developed. Utilizing the framework, the 5-year performances of the quasi-public bus system in Busan are evaluated. Acess, agency and public interests are employed as criteria for publicness evaluation. Financial aspects of operators, labor, vehicle utilization, productivity and operational costs are selected as indicators for efficiency evaluation. The results show that the publicness of bus services has been vastly improved, while the efficiency has been also improved in most areas except in cost and vehicle utilization aspects. The results of this study will be of use for planners and policy-makers developing strategies for system improvement. It is hoped that this study can be further refined by adding and adjusting indicators which this study may neglect or ignore.

This paper empirically analyzed the factors of operational efficiency after the quasi-public bus operating system in Busan Metropolitan City. DEA analysis result, for CRS the annual efficiency in 2010 of bus routes that can be transferred to subway lines 1 was the highest. The annual efficiency of bus routes that can be transferred to subway lines 2 shows the largest annual average of 0.923 in 2016 under the CRS average gradually improved over the year. Annual efficiency of subway lines No. 3 and transferable bus routes gradually improved from 2009 to 2015, but declined again in 2016. Among 536 routes for four years on 134 routes per year, 205 routes were found to be inefficient. In order to increase efficiency of the 205 routes, it is suggested that the number of routes should be reduced. In addition, the analysis results on DEA using the Tobit calibration, the most significant factors affecting the operational efficiency index were the time taken, followed by the number of passengers and the number of passengers transferred.

As examples of the region's transition to quasi-public goods a previous stage of full public goods also extremely limited in research. However, in this way can it compensate for this paper as a system to minimize moral hazard by electronic information and communication systems focused on safety in accordance with the methods and gave public goods introduction of grafting of electronic information systems played the Yeosu area to specific cases I went to the deployment.

Busan Metropolitan City government has been implementing the local Bus Quasi-Public Operating policy since 2007. As a result of the policy, financial burden to cover financial deficit has become a big social issue. For successful settlement of the policy, the government should be able to gradually cut off the financial support for the deficit by continuously increasing the bus demand, which can be accomplished by providing more convenient bus services. The weather conditions that affect the public transportation demand include rain, fog and snow. They affect the mode choice for public transportation use, which in turn results in decrease in bus demand. In short, the adverse weather conditions result in significant profit loss of bus transportation, and consequently it financially burdens the City of Busan. In this research, the pattern of travelers' use of transportation modes given various weather conditions was analyzed. In addition, the reasons why people transfer from one to other transportation modes were analyzed by conducting a field survey, and policy implications on desirable public transportation facilities and transfer system were discussed.

The city of Busan implemented the 'Bus Quasi-Public Operating System' as a part of the Public Transit Activation Policy. Although the reorganization of routes and fares had temporarily increased the number of passengers, it is facing a downtrend currently. This implies the limited capability of increasing the use of the city buses only by adjusting the systematic components of the system. Thus, the research aims to analyse the effect of improving the 'kindness service' as an alternative way to vitalize the use of city buses. The analysis uses the survey encompassing sixteen 'kindness service' factors that was collected from the passengers and the drivers of the city buses in Busan, and some of the notable findings are followed. According to the analysis of determining the level of importance on the 'kindness service' factors, four major categories were derived; a category to maintain/reinforce the kindness service, a category to make incremental improvement, a category to encourage improvement, and a category to make focusing improvement. Using the categories, the study then performed the cluster analysis on 33 city bus companies in Busan to determine the differences between the companies. Consequently, the companies were grouped into four; two groups (14 companies) showing more importance on the kindness service while the other two groups (19 companies) showing less. In addition, multivariate an analysis of variance (MANOVA) identified the significant differences of the four categories among the groups of companies, and the findings were taken into consideration on further improvement plans of kindness service in the city buses of Busan.
