Abstract

While the vehicle detector is collected from a variety of information was mainly used as a real-time data. Recently scheme of application for archived traffic data has become increasingly important. In this background, this research were conducted on the improvement of the preprocessing for archived traffic data application. The purpose of improving specific preprocessing was reflect transportation phenomena by traffic data. As evaluation result, improvement preprocessing was close to the actual value than exist preprocessing.

그간 차량검지기로부터 수집되는 다양한 정보는 주로 실시간 자료로 이용되었으나 최근 교통데이터 이력자료의 활용방안에 대한 중요성이 증대되고 있다. 이러한 배경에서 본 연구는 차량검지기자료의 이력자료 활용을 위한 전처리 개선에 대한 연구를 수행하였다. 실제 교통현상과 가장 가까운 데이터 처리를 목적으로 세부처리로직을 개선하였다. 평가결과 기존 전처리 과정보다 개선 전처리 과정이 실제값에 가까운 결과를 나타내는 것으로 분석되었다.
