Abstract

The ITS performance evaluation has been performed in the evaluation of traffic data collection equipment. However, evaluation of the data collection equipment alone cannot guarantee the reliability of the traffic information. So, ITS service evaluation has to be implemented institutionally. In this study, an evaluation method has been prepared to evaluate the accuracy of travel time information in road sections. In addition, a piece of portable reference equipment was developed to collect travel time data on the road. Field tests were performed on two national road sections managed by the Seoul Construction and Management Administration (SCMA) to prepare an evaluation method considering field conditions and evaluate the reference equipment's performance. Based on the test results, the improvement of the reference equipment to collect more samples and the adjustment of collection points were discussed.

현재 ITS 성능평가는 교통정보 수집 장비에 대한 평가를 중심으로 시행하고 있다. 하지만 교통정보 수집 장비에 대한 평가만으로는 도로 이용자에게 제공되는 교통정보의 신뢰성을 보장할 수 없기 때문에 ITS 서비스를 평가할 수 있는 제도적인 뒷받침이 필요하다. 본 연구에서는 도로 이용자가 제공받는 구간 통행시간정보의 정확도를 평가할 수 있는 방법을 검토하였다. 그리고 실제 도로에서 데이터를 수집하기 위하여 이동식 평가 기준장비를 개발하였다. 개발한 평가 기준장비에 대한 성능평가와 현장 여건을 고려한 평가 방법을 마련하기 위해, 서울청 관할 국도 2개 구간에서 시범평가를 수행하였다. 평가 결과, 서울청에서 제공하는 통행시간정보는 90% 이상의 정확도로 높게 나타났다. 시범평가 결과를 바탕으로 표본 수를 늘리기 위한 기준장비 검지 방식 개선과 수집지점 위치 조정에 대한 사항을 논의하였다.
