The main purpose of this study is to find the exact origin-destination composition of import and export container traffics in Korea, because it is very important data to decide where to build ports or roads. Although there were several studies like this, those had many problems to apply real world because of limited data and the range of their research. So, as a matter of fact, this study is a first origin-destination research in Korea.
The samples are chosen from 28 trade ports, especially from 7 which have experiences in handling containers in 2002. The samples that are collected at the gates of each ports during 3 months in 2001 are 3.82% of total container volume in Korea. In this study, we adapt random sampling because stratified sampling is impossible due to the limited knowledge about population of origin-destination. The sample error is ±2.5% under the 95% confidence level.
The main result of this study is as follow.
- Contrary to our expectation, container volume to and from Metropolitan area only explain 28.7%. Before this study, many people expect the ratio will be about 40%.
- Gwangyang container port is yet far from national port because it heavily relys on near provinces, such as Junranamdo, Junrabugdo, and Gwangju. These three provinces explain 70.1% of throughputs of Gwangyang container port.
- Excluding Gyungsang province, the time required to Gwangyang port is far less than Busan port in almost all areas.
- Environmental costs from the traffic to Busan was 3 trillion won compared with 229 thousand won in Gwangyang. Busan explained 93% of total environmental costs from the container traffic between ports and inland areas.
