Multi-purpose freight car is applicable for both bulk freight and containerized freight to cope with the unbalance between demand and supply due to the demand variation by seasons or directions. In this paper, we suggested the advantages of introducing attachable container to railway freight transportation and possible freight items to use multi-purpose freight car. This results can be used to analyse the amount of attachable container and the feasibility of introducing multi-purpose freight car to railway.

This study highlights the main effect of job demand, work shift, work environment and stressors on the railway traffic controller's health, and the moderating effect of work0life balance. The result of empirical analysis based on questionnaires received from 328 traffic controllers working at 10 railway operating companies indicates that job demand, work shift, work environment and stressors have significant effect on their health, among which stressors is a major factor. In the respect of moderating effect, WLB showed no significance except for job demand. This result implies that controller's health can not be enhanced through their individual family or leisure life. Therefore, effective countermeasures and policy to mitigate their health problems and heal their symptoms are urgent.

It is very important that the calculation of railroad track capacity in infrastructure investment analysis and train operation planning. The dwelling time is one of the factors that influence in railroad track capacity. Current research in dwelling time has been focusing on theoretical investigation, the state of the research in effective variable (dwelling time etc) is insufficient. In this paper, we clearly draw the concept of railroad track capacity and the estimate on modeling of relationship railway demand and dwelling time. Also, we compare and analyze the variation of railroad track capacity according to transit railway demand in Gyeongin Line (Guro~Inchon). This paper is expected to contribute for improving on the in-using equations and methods in train operation planning as well as for improving level of service on railway user.

논문에서는 도시철도의 변전소의 최대수요전력을 줄이기 위한 새로운 방법으로 OLTC(:On Load Tap Changer)를 갖는 변압기의 사용을 제안한다. 국내의 대부분의 도시철도는 전동차에 필요한 전력을 다이오드 방식으로 정류하며 DC 1500[V]로 공급한다. 변전소가 병렬로 연결되어 있기 때문에 수전전압이 상승하면 정류기 전압도 상승하게 되고 변전소의 최대전력도 증가하게 된다. 시뮬레이션 결과를 통해 본 논문에서 제안하는 방법이 최대수요전력의 증가를 상당히 제한할 수 있음을 보인다.

The aims of the demand response market are stabilization of the power supply and improving of the reliability of the power system. The various applications of the energy storage system (ESS) in the railway systems are studied and implemented to raise the energy efficiency. It is one of the most important how to determine the obligation reduction capacity (ORC) in participation to the demand response market because it has an influence on the profit extremely. In this paper, when participating to the demand response market with demands in the urban railway, we calculated the available ORC and economically evaluated ESS based on the real load data.

Recently, there has been growing necessity to estimate the future travel demand of high speed train because the circumstance of high speed train service is rapidly changing with the launching of 2011 second stage of Gyeongbu high speed railway(Dongdaegu-Busan) and the completion of 2014 first stage of Honam high speed railway(Yongsan-Gwangju), etc. This study was designed to estimate future travel demand by analyzing the transport performance and train service characteristics of Gyeongbu and Honam line. This study presents the maximum load section and the changed future travel demand, which will be applied to establish a train operation plan.

Purpose - Among the various pricing approaches used to set fares for express trains, this study explores a method of utilizing a customer-based pricing approach. The purpose of this study is to figure out how to apply the customer-based pricing approach to fares of new railway services using express trains. Research design, data, and methodology - This study was conducted through a literature review and case studies. In the literature review, we examined three approaches, focusing on the customer-based pricing approach and its application. In the case studies, we show how a customer-based pricing approach can be applied to determining the fares for railway services. Result - Some studies have used a customer-based pricing approach to set railway service rates, adapting the concepts of customer-based pricing such as demand, elasticity, value and willingness to pay. When setting fares of new railway services, it is recommended to use the customer-based approach in conjunction with other pricing approaches. Conclusion - This study demonstrates that a customer-based pricing approach is a promising tool in making decisions on railway fares. By applying a customer-based pricing approach to fares for new railway services using express trains, railway operators can utilize new service rates and increase the profitability of the railway business.

KTX Introduced in korea have occurred enhanced services and reduced regional travel time. "Induced traffic" is defined in the traffic demand generated in new project. 'Induced traffic' compared to the Diversion Demand Survey and research on ways to quantify the situation, insufficient analysis of constant and long-term observations are needed to estimate the changes in demand. In this study, Induced traffic effects due to the opening of KTX for analysis survey to passengers by Railway and the scale factor induced traffic review.

2007년 7월부터 시행되고 있는 수도권 대중교통 통합요금제는 이용자의 통행비용 절감 및 활발한 환승행위의 유도로 긍정적인 평가를 얻고 있다. 그러나 수도권 대중교통 통합요금제를 고려한 철도 수요예측 방법론, 특히 수단분담과 관련된 연구가 많지 않았다. 이에 본 연구는 수도권 대중교통 통합요금제를 반영할 수 있는 수단별 효용산정기법을 제시하였으며, 2006년 가구통행실태조사 자료를 활용하여 통행시간과 통행비용 산정에 적용되는 계수를 현실화하였다. 그리고 다양한 요금제를 적용하기 위한 철도 수요예측 방법론을 제시하였다. 본 연구에서 제시한 철도 수요예측 방법론은 철도 수요예측의 정확성과 유용성을 향상시키는데 기여할 수 있을 것으로 기대된다.

철도서비스 개선을 위한 기존선의 복선, 전철화, 상호직결운행 등 철도네트워크의 기능강화사업이 활발히 추진되고 있다. 본 논문에서는 철도네트워크 기능강화와 같이 새로운 철도서비스가 제공될 경우 타 교통수단으로부터 어느정도의 전환수요가 발생되며, 철도이용패턴은 어떻게 변화될 것인지에 대해 대구권 철도서비스 개선의 사례연구를 대상으로 SP와 TP자료에 의한 전환수요분석모형을 검토하였다. 모형분석 결과, 총통행시간과 통행비용의 파라미터 추정치가 충분한 설명력을 나타내고 있으며, 특히 SP의 보완적 조사로서 TP데이터를 이용할 경우, 철도요금과 통행시간 설정에 따라 전환수요경계치를 쉽게 파악할 수 있어서 대구권 광역철도를 비롯하여 타 지역에서도 보다 실용적으로 적용할 수 있을 것으로 판단된다.
