Abstract

This study is focused on the effect of reformation of public transportation system on the efficiency of bus route system as a result of change of government subsidy scheme. Two types of government subsidy scheme has been considered and before and after analysis by Data Envelopment Analysis technique has been carried out for bus routes in Ulsan Metropolitan City. The analysis output has shown that there is no clear evidence to clarify the relationship between the change of government subsidy scheme and the efficiency of bus route system. There are two types of backgrounds may be suggested for this situation such as more longer period necessary to identify the policy effect and limitation to increase the number of passenger in a provincial city. Tobit regression analysis has also been conducted to discover the most effective variables for maximum efficiency and three variables including route length, frequency per vehicle per day, and headway are found to be influential. It is also seen that strategy to minimising input factors and service upgrade plan such as shortened route length and headway, increasing frequency per vehicle are necessary to develop the efficiency of bus routes operated in Ulsan city.

본 연구에서는 버스업체에 대한 재정지원체계 변화가 버스노선의 효율성에 미치는 영향을 분석하였다. 최근 들어 증가추세에 있는 버스운행에 대한 지방자치단체의 재정지원은 안정적인 대중교통 서비스 제공을 목적으로 하기 때문에 효율적인 버스 노선 운영이 반드시 수반되어야 한다. 이러한 배경으로 본 연구에서는 요금조정(현실화)과 인센티브 재정지원의 두 가지 재정지원체계 시행에 따른 버스노선의 효율성 변화를 울산광역시를 대상으로 자료포락분석기법을 적용하여 제도시행 전후의 버스노선 효율성을 비교 분석하였다. 분석결과 재정지원체계 변화가 버스노선 효율성 개선에는 크게 영향을 미치지 않는 것으로 분석되었는데 이는 정책시행효과를 분석하기에는 분석기간이 다소 짧았고 지방도시의 대중교통수요는 한정되어 있어 무조건적인 승객 증가에는 한계가 있기 때문이다. 효율성 결정요인 분석결과 운행거리, 대당운행횟수, 배차간격 등이 유의한 변수로 도출되었는데 울산시 버스노선의 효율성을 향상시키기 위해서는 투입요소의 절감방안 마련과 함께 노선의 운행거리 단축과 대당 운행회수 증가 및 배차간격 단축 등을 적극적으로 시행할 필요가 있는 것으로 분석되었다.
