Abstract

As vehicle supply rate increases, traffic jam-related problems emerge and sharing transportation including carpool, centered on the advanced countries, becomes a major interest. This study aims to analyze benefit generated by carpool during the rush hours of medium and long distance travel, focused on the workers of public Agencies relocated to innovation cities. In order to compute benefit, carpool demand of relocated public Agencies was estimated and travel speed was estimated according to reduced traffic volume through carpool adoption using a traffic flow model. The benefit were computed dividing them into direct benefit and indirect benefit. As a result, 23billion KRW and 56.5billion KRW were annually revealed to be generated in terms of direct benefit and indirect benefit. The study result is expected to be used as part of basic research to adopt carpool for future traffic demand management.

자동차 보급률이 증가함에 따라 교통 혼잡과 관련된 문제가 대두되고 있으며 선진국을 중심으로 카풀 등의 공유교통이 주요 관심사로 떠오르고 있다. 본 연구에서는 혁신도시 이전공공기관의 기관 내 종사자를 대상으로 중 장거리 출 퇴근 시에 카풀을 도입할 경우에 발생하는 편익을 분석하는 것을 목적으로 하였다. 이를 위해 이전공공기관의 카풀 이용 수요를 추정하고 교통류 모형을 이용하여 카풀을 도입함에 따라 감소하는 교통량에 따른 통행속도를 추정하였다. 편익은 직접편익과 간접편익으로 구분하였으며 분석결과, 직접편익과 간접편익은 연간 약 230억 원, 565억 원의 편익이 발생하는 것으로 나타나 향후 장래 교통수요관리를 위한 카풀 도입의 기초연구로 활용할 수 있을 것이라 기대된다.
