The necessity and importance of public transport in urban areas is increasing day ever. Jeollabukdo has the lowest satisfaction with public transport services among the eight provinces of Korea. The purpose of this study is to analyze the relative efficiency for the satisfaction of the bus passengers targeting Jeollabukdo 13 intra-city bus companies. And after measuring the efficiency of the each intra-city bus company, it will increase the satisfaction of passengers and increase the efficiency of the ineffective intra-city bus company and to derive a realistic way.
In this study, decision-making unit(DMU) was determined as 13 intra-city bus companies in Jeollabukdo. Inputs of the bus company was chosen as the number of employees per bus and modernized bus, driving times, cost-benefit ratio. As a result of the ANOVA analysis, modernized bus of 13 intra-city bus companies in Jeollabukdo has been analyzed that there is no difference and other things has been analyzed that there is a difference. Based on the DEA results, among 13 intra-city bus companies in Jeollabukdo the most efficient companies were to use as evidence for the benchmark. And inefficient companies were distinguish whether the cause of inefficiency that the scale factors, technical factors, and was to be utilized as the basic data, in order to increase the efficiency of satisfaction was to be utilized as the basic data.

The results are as follows. In this study, the relative efficiency was analyzed through analysis of the CCR and the BCC analysis. As a result, the average technical efficiency was shown by 0.9522, it shows the inefficiency of about 5%, disassembling the inefficiency of approximately 5% can be expressed as pure technical efficiency and scale efficiency. The average pure technical efficiency was shown by 0.9705, it shows the inefficiency of about 3% and The average scale efficiency was shown by 0.9803, it shows the inefficiency of about2%. In other words, the causes of the inefficiency of 13 intra-city bus companies in Jeollabukdo are saying that they are caused by pure technical efficiency. In order to increase the efficiency of satisfaction of bus users, than reduction or expansion of the scale, efficient input of internal resources are needed.
