Abstract

The purpose of this study is to propose a methodology for operating variable speed limit (VSL) strategies in freeway work zones. A notable feature in this study is to incorporate a multi-criteria decision making process into deriving better VSL strategies. Decision criteria in this study include operational efficiency, safety, and environmental impacts. Travel speed, acceleration noise, and CO2 were used as performance measures for evaluating VSL strategies. A multi-criteria value function was developed through an analytical hierarchical process (AHP) for representing expert's knowledge. Then, a variety of VSL operations scenarios were investigated utilizing a microscopic traffic simulation suite, VISSIM. The proposed methodology would be useful in supporting more efficient, safer, and more environment-friendly traffic operations and control in freeway work zones.

본 연구에서는 고속도로 공사구간에 이동이 가능한 PVMS(Portable Variable Message Sign)를 일정 간격으로 설치하여 VSL을 구현하는 교통류 제어전략을 구성하여 공사구간에 어떠한 영향을 미치는지 파악하고자 하였다. 다기준 의사결정 기법 중 하나인 AHP기법 및 다기준 가치함수를 이용하여 교통소통, 교통안전, 환경을 대표하는 척도들을 동시에 고려할 수 있는 평가 방법론을 정립하였으며, VSL전략의 도입 전 후 개선효과를 도출하고 실시간으로 수집되는 교통량 및 중차량 혼입율을 고려한 최적 VSL전략 대안선정을 연구의 목표로 하였다. 개발된 평가 방법론을 통해 시뮬레이션 결과를 분석하였으며, 결과의 통계적 유의성 검정을 위해 분산분석을 수행하였다. 분석결과, VSL 대안 2(PVMS 400m간격)가 6개의 Case에서, VSL 대안 1(PVMS 200m간격)이 5개의 Case에서, VSL 대안 4(PVMS 800m간격)는 1개의 Case에서 최적 대안으로 도출되었다. VSL 대안 3(PVMS 600m간격)는 모든 Case에서 최적 대안으로 선택되지 않았으며 4개 Case에서 가장 안 좋은 대안으로 나타났다. 이는 VSL전략이 항상 개선된 효과를 보이지 않는 것을 의미하며 교통상황별로 적정 대안의 도입이 필요하다는 것을 나타낸다. 본 연구에서 시도된 AHP기법을 이용하여 여러 효과척도를 복합적으로 고려한 교통류관리전략 평가방법은 향후 다목적 의사결정방법의 교통류관리전략에 적용 시 하나의 예시가 될 수 있을 것으로 기대되며, 연구에서 제안하는 PVMS를 이용한 공사구간 VSL전략은 교통정보센터에서 실시간으로 수집되는 데이터를 통해 교통류 관리를 위한 운영 및 제어방안에 활용될 것으로 기대된다.
