TCS 자료를 이용한 고속도로 화물자동차 O/D 구축방안

Abstract

Toll collection system (TCS) data which includes entry and exit travel information on expressways was used to validate regional truck travel demand estimates. There were, however, some limitations to estimate a zonal truck OD on expressways using the data. Vehicle classifications in TCS did not separate freight trucks from other vehicle types such as cars or buses, and an original departure before entering an expressway and a final destination after exit an expressway were not collected in TCS. Fortunately, new information is suggested that helps solve existing problems as current travel information such as OD is collected for commercial trucks using highway tollgates and some tollgates example the proportion of vehicle types. This study aims to provide how to estimate a zonal truck OD on expressway using both TCS and survey data. In this study, a truck OD between tollgates operated by Korea Expressway Corporation was adjusted considering traffic information at privately operated tollgates and vehicle classifications was re-specified by truck type (small/medium/large) through survey data. Consequently, a zonal truck OD travel on expressways based on truck OD between tollgates was estimated, and the reasonability was presented through trip assignment results and generations/ attractions by region.
