Abstract

Cheongju-si implemented the bus semi-public system for the first time among basic local governments in 2021, However, as fiscal expenditures are increasing rapidly every year, it is time to improve the efficiency of bus operations. Therefore, this study analyzed the efficiency of bus routes operating in Cheongju-si, weekdays and weekends, which yet to be known in previous studies, and the efficiency analysis of routes with weekend reduction operations. For the analysis, 55 routes were selected based on Cheongju-si's internal and BIS data. And a DEA (Data Environment Analysis) was performed after dividing them into three groups, and factors affecting the efficiency of bus routes were explored through Tobit regression analysis. As a result of the analysis, the efficiency of Cheongju-si bus routes by the group was the highest in the arterial express line, 77.9% on weekdays and 75.1% on weekends compared to the arterial expression, and 67.6% on weekdays and 61.9% on weekends. In addition, weekend efficiency compared to weekdays was 14.1% lower overall on the route, and by group, the arterial expression was 11.0%, the outer 14.3%, and the city circulation was 18.6%. Furthermore, the efficiency of the reduction operation improved on 19 of the 21 routes where weekend reduction operations were taking place, which was 9.0% of the city cycle and 12.6% of the outskirts. Finally, the factors influencing efficiency through Tobit regression analysis were found in the order of number of operations, distance and busstop, curvature. These results are expected to contribute to preparing policies to ease the financial burden, such as improving the efficiency of bus operation in Cheongju in the future.
