Abstract

Demand Responsive Transport (DRT) ran in rural areas has being distinctly operated as various ways even within the same areas under the regional conditions and limited budget. DRT efficiency is significantly considered by the regional operators for effective operation, users’ satisfaction, its future expanding plan, and so on. The reasonable policy for efficient DRT system is necessary for its expanding operation in the public transportation remote areas having the aggravating population decrease and aging. The study offers the yardstick for the new or expanding DRT system by analyzing the relative efficiency and the influencing factors based on the characteristics of current DRT. The best optimal efficient Eup·Myeons and the inefficient ones are respectively presented depending on the values of technical efficiency, pure technical efficiency, and scale efficiency calculated by Data Envelopment Analysis to evaluate forty-eight Eup·Myeons of eleven cities and counties currently operating DRT in the Jeonbuk State. Especially, The step by step process to improve inefficiency is fulfilled by the Tire Analysis for inefficiency Eup·Myeons to become the efficiency ones. The influencing factors on DRT efficiency are analyzed by the ordered probit model. It is expected that the results of this study will be to offer the useful guideline for DRT introduction and to guarantee the mobility rights for residents in the public transportation remote areas.

농어촌지역에서 운영되는 수요응답형교통(DRT)은 동일 시·군내에서도 지역여건과 한정된 예산 범위 내에서 대상자, 운영기준, 운영지역 등을 고려하여 다양한 방법으로 운영중이다. 이런 상황을 고려하여 운영자 측면에서 지역별로 운영특성과 만족도 등을 기준으로 효율성이 중요시 된다. 연구대상지인 전북특별자치도와 같은 인구감소 및 고령화가 심화되는 지역에서는 DRT 확대를 위해 효율적인 운영방식에 대한 정책방향이 필요하다. 연구는 현재 운행중인 DRT의 운영여건과 관련한 요인을 기초로 효율성 값을 산정하고 최적의 읍·면이 되기 위한 참조대상을 제시하여 향후 DRT 신규 도입 및 확대·운영시 정책판단의 기초자료를 제공하고자 한다. 자료포락분석(Data Envelopment Analysis)을 적용하여 전북특별자치도내 DRT를 운영하는 읍·면을 대상으로 기술효율성, 순수기술효율성 및 규모효율성을 제시하고 효율적 및 비효율적 지역을 선정하였다. 특히, 비효율적 읍·면이 상대적 비교에 따른 완전한 효율성을 확보하기 위해 참조해야 하는 읍·면을 Tier 분석의 단계적 과정을 통해 도출하였다. 순위회귀모형을 통해 효율성에 영향을 미치는 요인들을 분석하였으며, 연구결과는 인구감소 및 고령화가 진행중인 대중교통공백지역에서 주민의 이동권을 보장하기 위한 DRT의 가이드라인이 될 것으로 기대한다.
