Abstract

Road Geometry design manual in Korea guides the application of different design standards for urban roads compared to rural ones. The two types of roads are quite different in terms of their use. This study aims to develop indicators that can classify urban and rural roads. Firstly, it summarizes the main characteristics of urban and rural roads based on the previous literature. Then it suggests four quantitative indicators such as the number of crossings, access roads, property access points, and bus stops per kilometer. The application of these indicators to the arterial roads in Seoul and Ulsan metropolitan cities using K-means clustering analysis shows that it is appropriate to classify roads into three clusters. It turns out that cluster 1 represents rural roads, and clusters 2 and 3 represent urban roads. The developed indicators can be useful to identify road sections of speed limit reduction which is usually targeted to urban roads only. They also can be useful in deciding whether or not to install new crossings or access roads in the existing roads.

우리나라의 「도로의 구조 및 시설에 관한 규칙」에서는 설계기준을 적용할 때 도시부 도로와 지방부 도로를 구분한다. 두 유형의 도로 이용 특성이 확연히 다르기 때문이다. 본 연구는 도시부 도로와 지방부 도로를 구분 짓는 정량적 분류기준의 적용 방안 제시를 목적으로 한다. 이를 위해 우선 국내외 문헌에서 제시하고 있는 도시부 도로와 지방부 도로의 주요 특성을 정리한다. 특히 미국의 도로설계지침에서 최근 도입된 맥락적 분류 기준을 설명한다. 이후 이를 기반으로 정량적 분류 지표로 km당 횡단보도 수, 접근도로 수, 건물 진출입지점 수, 버스 정류장 수 등 네 가지를 선정하였다. 이후 서울, 울산 등의 주요 간선도로를 사례로 네 개 분류 지표를 이용하여 k-평균 군집분석을 시행하였다. 그 결과 3개의 군집으로 구분하였을 때 가장 차이가 뚜렷했다. 군집 1은 지방부 도로의 특성을 가지며 군집 2와 3은 도시부 도로의 특성을 가지는 것으로 나타났다. 이러한 분류기준을 이용하면 도로의 제한속도 설정 등 도시부 도로에 한정하여 적용하는 교통규제의 적용 대상을 선정하거나 도로의 이용 단계에서 새롭게 제안되는 횡단보도 설치, 접근로 연결 등의 타당성을 판단하는데 유용하게 활용될 수 있을 것이다.
