초록
본 연구는 고속도로 내 상습 지정체 구간 개선을 위해 도로 용량을 증대시키는 대표적인교통 운영 기법인 갓길차로제 시행의 효과를 분석하는 것을 목적으로 한다. 갓길차로 운영은차로 확장 등 큰 규모의 공사 없이 첨두시 교통소통을 개선하는 효과가 있어 잦은 정체 구간의교통 정체 개선 대책으로 활발히 사용되어 왔다. 국내의 경우 경부고속도로, 영동고속도로, 서울외곽순환고속도로에서 갓길차로를 운영 중에 있으며, 단계적으로 운영을 증가시켜가는 추세이다. 이에 따라 본 연구에서는 갓길차로의 운영 전후 효과 분석을 위해 1) 시공도 기반 개별갓길차로 운영 전후 효과분석, 2) 도로 축 단위 갓길차로 운영 전후 효과 분석으로 나누어 종합적인 분석을 수행하였다. 이를 통해 본 연구는 향후 고속도로 내 갓길차로 설치 및 효율적인교통운영관리에 기여하고자 한다.
Abstract
The objective of this study is to analyze the effect of the shoulder-use lane, which is a representative traffic management technique that increases the road capacity. The operation of the shoulder-use lane has been actively used as a countermeasure to improve traffic congestion, because it has the effect of improving traffic flow during rush hour. In Korea, the shoulder-use lanes are available at Gyeongbu, Yeongdong, and on the Seoul Outer Ring expressway, and their use is gradually increasing. Therefore, a comprehensive analysis was conducted to analyze the effects of the shoulder-use lane; including 1) analysis of individual shoulder lanes based on a time space diagram, and 2) analysis of shoulder lanes by road axis. These findings can contribute to the efficient installation and operation of shoulder-use lanes on expressways.
