군집분석을 이용한 도시간선도로의 도로기능분류

Abstract

There have been studies on grouping highways by its functions, but almost no studies were made for grouping city highways. Due to heavy traffics, city highways are not able to perform their own roles as a "highway". Also, the standard for grouping the highway by its functions are based on road planning and specifications which don't reflect the characteristics of traffics. For those reasons, I have organized city highway's functions by using Cluster Analysis with using traffic characteristic variations. I used traffic characteristics like traffic volume, figures for weekend traffic, speed calculation and etc. for each city highways to organize 55 city highways in Seoul by its functions. I have compared my outputs with outputs from using AADT method. Outputs from AADT method have classified the characteristic of highways by its total number of lines and traffic density, but I have used traffic density per line as my main variation to come up with outputs which reflects the actual traffic. Also, I have proved my experiment that it reflects characteristics of traffics by comparing my analysis to Seoul City highway function assortment system. Conclusions for my paper(thesis) are first, my proposal is more effective than present highway grouping method which can not reflect some characteristics of present highways and second, function grouping system which I propose, will give more positive effects in designing and planning seoul highways for its extension.
