Regional Freight Demand Estimation Using Korean Commodity Flow Survey Data

A commodity flow survey (CFS) is conducted to analyse commodity flow characteristics and to compile statistics for goods movement in several countries. In Korea, the CFS has been conducted every five years since 1998. Freight travel information collected through this survey is mainly used to estimate freight demand as well as freight statistics. This paper provides details of the Korean CFS and introduces a procedure for regional freight demand estimation. Though freight demand focuses on commodity flow, the conversion of commodity flow into the equivalent number of trucks and traffic assignment for truck trips is also presented.
