관광부 도로의 판별 및 교통 특성에 관한 연구

Abstract

This study is to discriminate recreational roads using various traffic indices as well as to identify traffic characteristics for it. To accomplish the objectives, factor analysis and cluster analysis are performed for classifying highway and analyzing traffic characteristics using traffic data that observed at permanent traffic count points in 2003. A total of 8 variables are applied : AADT, K factor, D factor, heavy vehicle proportion, day volume proportion, peak hour volume proportion, sunday factor, and vacation factor. The results of factor analysis show that variables are divided into two factors, which are factor related to the fluctuational characteristics of traffic volume and factor related to heavy vehicle and directional volume characteristics. According to the results of cluster analysis, a total of 328 permanent traffic count points are categorized into three groups. Traffic characteristics are analyzed to verify the results, and recreational roads(group I) are discriminated. The traffic characteristics analysis shows that AADT is 7,000 vehicles per day, and 30th K factor is 18 percent for the recreational roads. Recreational roads show higher average daily traffic volume during Sunday and vacational periods.
