19세기초 영국에서 개발된 증기 기관차로 인하여 육상교통이 큰 변혁을 맞은 이래 열차의 속도, 승차감, 신뢰도 및 안전도, 경제성의 제고 등에 대한 계속적인 기술발전과 개량으로 철도 교통은 대량수송 수단의 주역으로 경제발전과 인류역사에 크게 공헌하여 왔다. 산업발전에 따른 고속화와 전철화로 철도차량의 최고속도는 프랑스의 고속전철(TGV)이 300km/h까지 도달했으나 고속주행시의 소음, 공해등으로 인하여 21세기 인류에게 제공될 지상의 대중교통수단으로서는 여러가지의 제한점을 보이고 있다. 최근 우리나라에서도 지속적이고 급속한 대중 교통수단으로서는 여러가지의 제한점을 보이고 있다. 최근 우리나라에서도 지속적이고 급속한 산업발전과 사회복지의 향상으로 국내의 산업물동량과 산업인구의 이동이 급격하게 증가하여 우리나라 산업동맥의 중추인 경부선의 경우 일일 수송능력은 120회/일 이르렀고 철도교통수요의 증가율('84년 예측치 5.9%년)과 특급이상의 승객증가율('84년 예측 12.5%)에 비추어 볼때, 1995년경에는 완전포화 상태에 도달할 것으로 예상되고 있다. 본 소고에서는 21세기 고도사회 진입에 대비하고 국민의 생활수준향상에 부응하는 빠르며, 쾌적하고, 안전한 고속 대중 교통수단으로써 관심을 불러 일으키고 있는 고속전철을 소개하고, 현재 운행하거나 개발중인 외국의 기술현황을 기술적인 면과 운용면에서의 고찰을 통하여 한국의 교통체제, 지형, 미래의 교통구조 등을 고려한 한국형 고속전철의 개발방향을 제시하고저 한다.

본 연구는 지속적인 여객 및 화물량의 증가로 기존 수송수단이 포화에 이른 실정에 새로운 교통수단으로 추진한 고속철도 사업에 대해, 고속철도 개통 후 단기간에 드러난 이용현황 및 문제점을 도출해 기선방안을 제시하고자 한다. 이를 위해 관련 단체 및 기관의 자료를 수집 분석하였으며, 설문조사를 수행하여 결과를 도출하였다. 또한 광범 위한 고속철도 사업의 특성아래 여객 부문에 대한 대중교통 측면으로 연구의 범위를 한정하였다. 고속철도 개통 후, 여객 및 화물 수송의 형태에는 단기간이나마 큰 변화가 있는 것으로 나타났으나 그에 반해 고속철도의 이용에 있어서 주목할 만한 문제점 또한 조사되었다. 주요 사항으로는 역방향 유해성, 일반열차로의 불편전이, 터널통과시의 소음 등으로서 이는 개통 초기 고속철도에 대한 그릇된 대국민 인식을 가져오게 함과 동시에 향후 개인들간 교통수단 선택에 있어서까지 그릇된 영향을 끼칠 수 있다. 현재 각각의 문제점에 대한 개선방안으로 일반열차 확대 및 할인혜택, 점진적인 순방향 좌석으로서 교체 및 소음 저감방안을 위한 연구 용역 등이 실행되거나 준비되고 있으나 그에 대한 뚜렷한 개선 징후는 아직 미미한 상태로 분석되고 있다. 본 연구에서 실시한 설문조사 결과 아직까지는 고속철도에 대한 인식이 긍정적인 수준을 보이고 있으나 개별 문제점에 대한 좀더 깊은 고찰과 개선안 제시가 이루어진다면 향후 고속철도에 대한 대국민 인식을 한 단계 더 높여, 그 이용을 활성화 시킬 수 있는 좋은 기회가 될 것으로 판단된다.

This study aimed to analyze access mode choice behavior for KTX Passengers. To fulfill the aims of this study, Dong-Daegu Station was selected as a station for a case study. This study takes place in two stages. These are (i) descriptive statistical analysis of transportation status before and after introduction of the KTX, (ii) empirical model estimation for analyzing access mode choice behavior. This study makes use of the data from travel survey from Daegu metropolitan area. The main part of the survey was carried out in the KTX Dong-Daegu station. The data was collected from a sample of 1,800 individuals. The survey data includes the information on travel from Dong-Daegu station to Seoul. From descriptive statistical analysis of transportation status before and after introduction of the KTX, it is found that revealed demand of the KTX is lower than that expected. Moreover, it is found that the low demand of the KTX stems from high cost for the KTX itself and inconvenience( including travel time and cost) of access mode. In order to analyze mode choice behavior for accessing Dong-Daegu station, multinomial logit model structure is used. For the model specification, a variety of behavioral assumptions about the factors which affect the access mode choice, were considered. From the empirical model estimation, it si found that access travel time and access travel cost are significant in choosing access mode. Given the empirical evidence, we see that improvement of access transportation system for Dong-Daegu station is very important for enhancing the use of KTX.

Recently, the building of an intermodal transportation system has become the most important policy in the establishment of a national-wide sustainable transport system. In the case of rail and public transport, an intermodal connecting improvement policy is essential due to the lack of trip completeness. In particular, high-speed rail has brought dramatic changes to the transportation system in Korea and the idea of high-speed rail stations as major transportation nodes to be linked to various travel modes needs to be analyzed in terms of an intermodal network. Thus, this study proposes a new connectivity analysis method to objectively and quantitatively evaluate intermodal connecting performance for high-speed rail in terms of an intermodal network around high-speed rail stations. Seoul, Busan, Ulsan, and Sin-gyeongju stations were designated for a range of spatial analyses; detailed connecting performance indexes of travel modes connecting high-speed rail stations, and the influence sphere of these stations are analyzed, except for internal transfer facilities. Finally, this study proposes a connectivity analysis method that applies the structural equation model and develops a connectivity index.

The Korea high speed train was launched from Seoul to Busan of 1st construction phase at 1st April, 2004. This huge project will be lead to a great change in korean society such as existing mode choice behavior change and the concentrating on KTX station zone lifestyle pattern's change. With the result to opening high speed train railway was diminished train journey time between Seoul to Busan from 4 hours 10 minute to 2 hours 40 minutes, and has been change population movement, favorite location of corporation headquarters, existing metropolitan transportation pattern and so on. In the middle of this study, I choose to analyse Seoul-Cheonan/Asan stations, Seoul-Deajeon stations, Seoul-Deagu stations, Seoul-Pusan stations. This study have a information to analyse among as like movement of population, status of employee structure, usage of land, movement inland transportation mode. I sure that this study will lead to helpful prediction both 2nd phase of Kyoung-bu high-speed railway and Ho-nam high-speed railway in advance.

As sustainable growth has been emphasized in the field of transportation, the railway system has been promoted as an environmentally-friendly transport mode. However, mode shifts from other transport modes to railway have been sluggish. In this context, to enhance the understanding of railway's competitive advantages and disadvantages, this research evaluates travelers'preferences for public transport modes for inter-regional trips: such understanding should make it possible to formulate effective policy for promoting railways. To this end, passenger recognition of competitive transport modes has been measured by applying multidimensional scaling analysis for six major inter-regional public transport services - KTX, ITX-Samaeul, Mugunghwa-ho, premium express bus, general express bus, and airline. As a result, we can conceptualize the recognition similarity in two-dimensional space, and understand how travelers perceive the six major transport modes.

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.

Most of Korea's 15 local airports, with the exception Jeju, Gimpo and Gimhae airports, have been several billion Won in the red each year. It has been reported that one of the causes of the poor financial performance is inaccurate air traffic demand predictions. Under the situation, the entry of low-cost carrier air service using turbo-prop airplanes into the domestic airlines market gets a wide range of support, which is expected to promote the convenience of consumers and help to activate local airports. In this study, the authors (1) suggest a high-speed transport demand model among existing airlines, Korea Train Express (KTX) and low-cost carrier air service; (2) try to make low-cost air carrier demand predictions for a route between Seoul and Daegu through a stated-preference survey; and (3), examine possible effectiveness of selected policy measures by establishing an estimation model. First, fare has a strong influence for mode choice between high-speed transport modes when considering the entry of low-cost carrier air service between Seoul and Daegu. Even low-cost carrier air service fare is set at 38,000 won, which is considerably low compared with that of KTX, in the regions where the total travel time is the same for both low-cost carrier air service and KTX, the probability of selecting low-cost carrier air service is 0.1, which shows little possibility of modal change between high speed transportation means. It is suggested that the fare of low-cost air service between Seoul and Daegu should be within the range of from of 38,000 to 44,000 Won; if it is higher, the demand is likely to be lower than expected.
