Abstract
일반적으로 고속도로는 대용량의 교통량을 높은 수준의 안전성과 효율성을 가지고 고속으로 이동시키기 위해 건설되었다. 국내 경부고속도로와 남해고속도로는 부산항을 기 종점으로 하는 핵심고속도로로 컨테이너차량을 포함한 수출입화물트럭의 집중으로 교통문제가 종종 발생하고 있어서 교통문제 완화를 위해서는 교통특성연구의 필요성이 제기되고 있는 상황이다. 그리하여 본 연구에서는 경부고속도로와 남해고속도로의 8차로 기본구간을 대상으로 차로별 점유율과 평균밀도의 상관관계를 통해 고속도로의 밀도추정모형을 제시하고자 하였다. Expressways are built to provide for high levels of safety and efficiency in the movement of large traffic volumes at high speeds. However, Gyeongbu and Namhae expressways in the country which are often suffering from the transportation problems with increased import and exoprt cargo trucks including the container vehicles are the major expressways having the Busan Port as the origin and destination regions, and are required to study the expressway traffic characteristics for reducing the transportation problems. We therefore attempted to suggest the expressway density predictive model through the correlation analysis between lane occupancy and mean density at the 8-lane basic segments of the above major expressways in the country.
