초록
교통관리에서 교통상황을 판단하는 판단지표의 중요성과 필요성은 계속해서 높아지고 있다. 기존 교통상황 판단지표들은 속도, 교통량, 밀도 기반으로 각각의 특성에 맞춰 개발되었지만, 속성별 가지는 문제점과 종합적인 상황을 보여줄 수 없어 모니터링 지표로는 적합하지 않았다. 이에 본 연구에서는 도로 소통상황과 안전도를 판단하는 지표들을 통합하여 모니터링에 적합한통합지표 개발을 목표로 하였다. 교통상황의 변화를 판단할 수 있고 안전도를 판단할 수 있는지표들을 검토하고 실시간 ITS 데이터를 적용할 수 있도록 지표를 재정립하였다. 요인분석을통해 지표 간 관계성을 분석하여 가중치를 도출한 뒤 하나의 통합지표를 개발하였다. 통합지표는교통상황의 변화와 안전도의 변화를 보여줄 수 있는 지표로 향후 교통정보센터에 적용하여 종합적인 교통상황을 모니터링할 수 있는 교통환경으로의 발전에 기여할 수 있을 것이다.
Abstract
In traffic management, gaps in understanding traffic conditions continue to exist. While the self-belonging problem indicator develops relative to speed, belonging, and self-based relative inclination, it does not apply elimination criteria that may indicate situations that contrast with attribute-specific problems. In this study, we develop integrated indicators that specify communication situations and safety levels for modeling. We review indicators of changes in traffic conditions and raise safety issues, reviewing the indicators so that ITS data can be applied, analyzing the relationships between indicators through factor analysis. We develop combined, integrated indicators that can show changes and stability in traffic situations and that can be applied in traffic information centers to contribute to the development of a traffic environment that can monitor related traffic conditions.
