Abstract

Network performance measure has been more and more important in transportation sector because traffic congestion has been steadily increasing in urban area. VKT is defined a sum of traveled distances of whole vehicles on the road network and one of the most important measure of effectiveness (MOE) for network performance measure. This paper aims to propose a methodology for estimating VKT and to apply it to calculate VKT in 6 major cities in Korea. We calculate VKT in 6 major cities by estimating traffic volumes on the uncollected road sections using regression kriging. It is expected that the proposed methodology can be applied various cities.

도시부 도로의 혼잡 및 지체가 매년 증가 추세를 보이고 있는 중 국내외에서 교통네트워크 성능평가에 대한 관심이 높아지고 있다. 교통네트워크 성능평가의 대표적인 항목은 차량주행거리를 들 수 있다. 차량주행거리는 해당 도로를 이용한 모든 차량들의 이동거리 합으로 다양한 교통정책분석의 기초자료로 활용되고 있다. 본 연구는 국내 6대 광역시를 대상으로 차량주행거리 산정방법론을 정립하고 이를 적용하여 차량주행거리를 산정하는 것을 목적으로 한다. 본 논문에서는 6대 광역시 대상 수집된 도로교통량과 회귀크리깅을 이용하여 추정한 교통량 미수집 구간의 교통량을 활용하여 차량주행거리를 산정하였다. 도시부 도로의 네트워크 형상과 교통량 미수집구간 위치에 따라 본 연구에서 제시한 교통량 추정방법을 향후 차량주행거리 산정에 있어 큰 효용이 있을 것으로 기대된다.
