Article
Efforts are needed to secure network reliability to prepare for unpredictable events such as natural disasters and terrorism. Previous network reliability analysis has been performed mainly on road networks, but inter-regional, and especially high-speed rail networks have not been studied. This study presents a network reliability analysis method a...
Article
It is important to compare the present condition of railway and marine freight transportation corridors to make good progress for freight transportation to the Eurasia region. This study is performed to investigate the current state of international corridors and to analyze mode choice characteristics between railway and marine transportation in th...
Article
For accurate demand forecasting of railway logistics, we estimated intercity freight mode choice models based on the binary logit model and using production-consumption data from the Korea Transport Database. We estimated two types of models and compared the results by major item of railway logistics, such as container, cement, and steel: 1) The ag...

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. Th...

It is a matter of common knowledge that the trucking industry has an important role in strengthening national competitiveness. Recently, in most countries, the trucking industry has faced the task of enhancing its efficiency. To achieve this, a detailed and objective assessment method for the efficiency of current trucking companies is required. Th...
Article
At the strategic level, multimodal freight network design problems are limited in that they reflect the costs and constraints associated with emissions. The network design problem (NDP) addressed in this study determines investment alternatives for minimizing total system cost, including costs related to greenhouse gas (GHG) emissions, while satisf...
Article
this study is to deduct the difference between regional and urban commercial trips by analyzing the characteristics of the regional and urban truck movements. To achieve this, we investigated the relation between the number of truck trips and various truck generation attributes such as truck attributes, origin and destination attributes, and commod...
Article
In Korea, almost 700 industrial parks are under operation. Generally, industrial parks consist of national industrial parks and local industrial parks which are managed by a central government and by local governments respectively. The developing countries such as Korea, China and Vietnam etc. have constructed many industrial parks, which result in...
Article
The purpose of this study is to propose a supplement to current freight demand model by analyzing factors that influence the generation of empty truck movements in regional and urban realms. To achieve this, we examined the relation between the number of empty truck trips and various generators such as truck attributes, origin type and attributes,...

Though the Bus Signal Priority (BSP) system is well known as an effective way to enhance the service quality of bus travel, the effectiveness of the BSP system significantly depends on the traffic and network conditions. Particularly, most previous use of the BSP system were applied as a corridor-based strategy targeting a few bus lines moving on a...
Conference Paper
Fluctuations in roadway capacity due to non-recurrent traffic incidents is a source of uncertainty of travel time. Travel time reliability, as a transportation performance measure, which may reflect travel time uncertainty was applied to network analysis. Recently, research which applies network reliability concepts to transportation network design...
