Abstract
High oil prices and traffic congestion have led to increasing relevant policies and interests in the use of public transportation. The bus service, one of the typical means of public transportation, has shown lower customer satisfaction compared to the subway and, moreover, the service's qualitative and quantitative evaluations are not sufficient. Therefore, this study has developed an evaluation model for bus service in order to consider the two service evaluation items, using structural equation methods. The algorithm can measure the customer satisfaction levels according to bus types as well as the importance of evaluation items and present total service satisfaction, making possible evaluation by bus routes as well as various bus types.
