To relieve congestion in the current system of intercity transportation, the Korea decided in 1990 to construct a high-speed railroad between Seoul and Busan and it is now in operation. This new mode of transportation significantly cut travel time between major cities and a trip from Seoul to the southeastern port of Busan. Since the KTX opening, average daily passenger numbers on both the Gyeongbu and Honam lines have increased about 1.3 fold over 2003 levels. As of December 2004, the KTX trains are carrying about 81,000 people a day. On KTX routes, the daily number of airline passengers dropped. Express long-distance bus traffic also dropped by 20% to 30%, while that on short-distance routes (100km or less) increased by about 20%. These figures clearly indicate that the Korean transportation network is becoming railroad-centric. However, the number of KTX passengers is fewer than anticipated possibly due to the Korean economic downturn and the operation of the KTX will leave many existing Saemaul and Mugunghwa train sets idle, which will be put into operation for areas, not covered by the KTX. When all the existing major lines have been electrified, more high-speed rail services will be phased in using direct connections to maximize operational efficiency. And also, the dual management by KTX and conventional rail will be regarded as the promotion of the benefit of the public.

The characteristics of intercity rail network are different from those of public transit network in urban area. In this paper, we proposed a new transit assignment model which is generalized form of deterministic assignment model by introducing line selection probability on route section. This model consider various characteristics of intercity rail and simplify network expansion for appling search algorithms developed in road assignment model. We showed the model availability by comparing with existing models using virtual networks. The tests on a small scale network show that this model is superior to existing models for predicting intercity rail demand.

남북한의 경제협력은 한반도 통합과정과 통일 한반도에 있어서 매우 중요한 의미를 지니게 될 것이다. 남북한 통합이 아직 속단할 단계는 아니므로 중장기적 전망이 타당하겠지만 러시아의 시베리아지역은 아ㆍ태지역과 유럽(중동과 서남아시아와 중앙아시아 포함)을 이어주는 교량의 위치에 놓여 있는 중요한 지역이므로 이지역을 둘러싼 국제적인 경쟁과 다양한 형태의 국가간 및 지역간 협력의 시대가 불원간에 도래할 것임을 전망할 수 있다.(중략)

Increasingly, the emphasis in regional Passenger rail Planning is finding ways to more efficiently use existing facilities, with particular attention being Paid to Policies designed to spread Peak-Period travel demand more evenly throughout the week with consideration of train classification. In this context the individual's choice of time to travel is of crucial significance. This paper investigates the use of multinomial logit analysis to model ridership by rail classification using data collected for travel from Seoul to Busan during the one week in October 2004. The Particular model form that was successfully calibrated was the multinomial logit (MNL) model : it describes the choice mechanism that will Permit rail systems and operations to be planned on a more reliable basis. The assumption of independently and identically distributed(IID) error terms in the MNL model leads to its infamous independence from irrelevant alternatives (IIA) property. Relaxation of the IID assumption has been undertaken along a number or isolated dimensions leading to the development of the MNL model. For business and related rail travel patterns, the most important variables of choice were time and frequency to the chosen destination. The calibrated model showed high agreement between observed and Predicted market shares. The model is expected to be of use to railroad authorities in Planning and determining business strategies in the Increasingly competitive environment or regional rail transport.

Since the 2000s, China has been trying to develop the mid- and western regions and reduce regional disparity between the eastern region and the others by construction of the eight HSR corridors known as 4+4. The high-speed railway is known to have a positive impact on regional economic development by improving accessibility between regions. However, some studies point out that the high-speed railways could worsen regional imbalances. The purpose of this study is to examine the impact of the high-speed railway on regional economic growth and balanced development in China, using the beta-convergence model. In particular, we focused on how the effects of high-speed trains on regional economic development varied depending on the level of development. The analysis was conducted centering on the Shanghai-Chengdu line which is connecting eastern, central and western regions with different levels of development.

The purpose of this paper is to propose a new transit assignment model for intercity rail networks. The characteristics of intercity rail are different from that of public transit in urban area. Line selection probability on route section is introduced to include the characteristics of intercity rail into transit assignment model. Network expansion is more simplified by a assumption line selection probability is externally given. The generalized cost is used to decide the volume of each transit line in most of existing transit assignment models. But, many variables have influence on the volume of each line such as time schedule of transit lines, inter-station distance, passengers' income, seasonal variation of demand and regional characteristics. The influence of these variables can be considered to decide the volume of each line by introducing line selection probability on route section. The tests on a small scale network show that the model proposed in this paper is superior to existing models for predicting intercity rail demand. Proposed model is suitable to consider the complicated fare structure of intercity rail and to draw inter-station demand directly as a result of assignment procedure.

기존의 철도용량의 개념은 하루동안 최대한 통과시킬 수 있는 최대 열차 횟수를 기본으로 하여왔다. 그러나 이러한 단순한 최대횟수는 그 사용상의 여러 가지 제한사항을 가지고 있다. 최대열차 운행횟수는 열차의 속도, 신뢰성등과 같이 고려하여야 하며, 이러한 고려는 자연스럽게 서비스수준과 같은 과거철도에서는 구체적으로 고려하지 않던 새로운 용량에 대한 접근을 요구하게 된다. 2004년에 세계철도연맹(UIC)에서 제안한 철도용량 산정절차는 이러한 측면에서 많은 점을 시사하고 있다. 새로운 절차의 한국의 지역간 철도에의 적용가능성을 검토해 본다. 본 연구에서는 2006년 11월 새로 개편된 경부선, 호남선의 열차시간표를 이용하여, 문제가 되고 있는 서울역${\sim}$시흥역 구간에 대해 UIC에서 새롭게 제시한 선로용량의 개념을 OpenTrack을 이용한 시뮬레이션을 통해 적용해보고, 이에 따라 선로 용량 산정시 적용할 수 있는 MOE를 찾아내 서비스수준(LOS)을 결정할 수 있는 방안을 제시해보고자 한다.

Korea, a peninsular country with distances of approximate 840 kms south-north and 1,200 kms east-west, currently has only three types of rail transport mode in operation; high-speed KTX, regional railway and urban rapid rail transit. It is very unfortunate that there exists no mountain train system across the country yet, which could be able to contribute both to the promotion of tourism and to a higher affordability of public transport means in the city. This type of rail mode system is more desiring when taking account the fact that 75% of the land topographically belongs to mountainous area. With this background in mind, among others, it is suggested that a mountain train system be laid over the scenic Bukhan Mountain in Seoul linking Gupabal station in line 3 and Ssangmun station line 4. This project would surely require an advancing review on its feasibility and approving result.
