  • The KTX train which brings April 2004 high-speed railroad commerce operation time is operated currently Kyungbu line Seoul-Gwangmyeong-Daejeon-Dongdaegu-Pusan and Honam line Youngsan-Gwangmyeong-Seodaejeon-Kwangju/Mokpo. The high-speed railroad opening to traffic after KTX train interior noise follows in railway line quality change and it is changing together. From the research which it sees until opening to traffic after present time of the KTX vehicle it executed an interior noise quality change from Kyungbu line.

  • Iksan is one of medium city in Jellabukdo, South Korea. It has a favorable natural environment for the specialization potential of natural industries and development projects. In addition, it has various historical and cultural resources including Mireuksajji, and KTX Honam line which has been opened for a representative feature as transport city. However, it faces week connection with neighboring cities and large scale of development in neighboring areas, especially in Jeonju and Gunsan. In this paper, we try to classify the urban image assets of Iksan as 'Iksan Station' and 'ktx' on keywords and analyze the possibility of being a center of transportation and logistics through big data analysis extracted from SNS and website. In comparison with Gwangju Songjeong, KTX Honam line station, which has been developed with similar regional characteristics, it is aimed to establish the basis of improvement and establishment of urban image of Iksan city in the future.

  • The KTX, first Korean Highspeed train from Seoul to Busan, is scheduled to begin its passenger service in 2004, with improvement of existing railroad between Daegu and Busan and Honam region. This paper aims to suggest the best train operation plan and detailed diagram pattern so that the KTX could work effectively as much as possible. I suggest for instance, connecting direct train and local train, hub stations plan, multi-destination train, and improvement of fare system.

  • 일반적으로 철도수요를 추정할 때에는 매표실적에 근거한 직접수요모형(Direct Demand Model)을 많이 사용하여왔다. 고속철도가 2004년 4월 개통됨으로써 실행된 수요가 나옴에 따라 이를 이용하여 KTX와 일반철도를 고려한 직접수요모형의 작성이 가능하게 되었다. 따라서 본 논문에서는 고속철도 운행 전${\cdot}$후의 실제수요를 이용하여 고속철도 개통 전${\cdot}$후의 직접수요모형을 추정하여보았다. 모형에 사용되는 변수로는 철도서비스, 사회경제지표 등을 사용하였다. 그 중 철도서비스, 즉 운행시간, 운행빈도, 운임 등을 집중적으로 사용하여 모형을 작성하였다. 이렇게 작성된 모형은 KTX와 일반철도, 일반철도 등급간에서 철도서비스 변수의 기여를 명시적으로 제시해준다. 개발된 모형을 이용하여 KTX 및 일반철도의 운행방향에 대하여 검토하였다.

  • The two projects about the high speed train have been performed in Korea, one project is the commercial run of high speed train(KTX) from Seoul to Busan and the other is the development of original high speed train(HSR 350x). As the successful results, the service run of KTX had been launched on the 1st of April, 2004 and HSR 350x had been fabricated in June, 2002 and has been tested in the Kyoungbu line and Honam line since then. The railway has the track irregularities which cause vibrations, such as rail joints, turnout, level crossing, transition curves and super-elevation ramps, and variations in the track level(z-axis) and the gauge(y-axis). Generally, the ride comfort for railway is evaluated by using the vibrations. In this paper, the ride comfort indices according to mc 513R and ISO 10056 have been reviewed when the high-speed trains are operated on both Kyoungbu line and Honam line. Also, the ride characteristics for KTX and HSR 350x on the high speed line and the conventional line have been analyzed and evaluated. The results show that the high-speed train has no problem from the viewpoint of the comfort ride on the high speed line and the conventional line and the ride index for HSR 350x is same as that for KTX in the high speed(300 km/h).

  • ccording to the airport railroad linkage facility expansion project constructing a connecting line to the airport railway and improving the signal system and Gyeongui Susaek Station, a high-speed train is able to run directly from Gyeongbu and Honam to the airport railway. According to mixed operation of high-speed Korea Train Express (KTX) and Airport Railroad Express (AREX) trains, to establish ERTMS/ETCS L1 ATP to operate the KTX train, the signaling system of the AREX train is the same as the existing ATC/ATO, but its operation became impossible because the high-speed train causes mutual interference between the "high-speed train (KTX) and AREX ground signaling equipment" and between the "AREX train and KTX (high-speed train) ATP ground equipment." Thus, it was necessary to have a supplemental technical interference analysis comparing the characteristics of the AREX beacon and the KTX balise. So, we resolve the problems of mutual interference between the "high-speed train (KTX) and AREX ground signaling equipment" and between the "AREX train and KTX (high-speed train) ATP ground equipment" with a test using an actual train, and we confirm the technical validity with three types of test module.

  • When constructing a high-speed railroad, the reduction of the distance between track centers and the width of track bed will save the construction cost. However the shortening the distance between track centers may cause the stability problems due to higher wind pressure. Therefore the extensive technical review and aerodynamical study should be performed to determine the adequate distance between track centers. In this study, the impact that the increase in wind pressure due to the change of aerodynamic phenomena with the change of the distance between track centers may have on two trains passing by each other was predicted, and the stability of train operation was analyzed in order to review the distance between track centers suitable to Honam HSR trains. And we estimated the aerodynamical effects by the results of the real train experiments by using KTX.

  • With increasing concerns of indoor air quality, $CO_2$ concentration in the public transportation, such as train, bus, and subway, draws big interests. The $CO_2$ concentration in the indoor air is regarded as index of ventilation status rather than that of adverse health effect. In this study, we measured the time-series of $CO_2$ concentrations in the KTX cabin during the journey of Gyongbu-line (Seoul-Busan) and Honam-line (Seoul-Mokpo) with the number of passengers on board. At the same time, the concentration of particulate matter (PM), temperature, humidity and gaseous pollutants including HCHO and VOCs were monitored. It is found that the $CO_2$ concentration was correlated linearly with number of passengers and was highly correlated with tunnel regions where the ventilation unit (flap) was closed.

  • KORAIL has improved profitability through abolition of nonprofitable route and withdraw rolling stocks, operated at that route. as a part of that process, most sections of commuters' train are gone. presently, gyeongui-line and gyeongwon-line's commuter's trains are operated. Despite the abolition, there are demands for commuters' train. so, nonprofitable route operation policies are needed to meet the demands and connect seamlessly to KTX. In this study, we consider the overall operation policies and problems of commuters' train in the past. and then, we analyze foreign nonprofitable route, connected with high speed train, operation policies and search for the development suggestions for applying to the nonprofitable route between Iksan - jeonju section at Honam and joenra line.
