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.

This paper explored an effective scheduling method for the Seoul-Busan High Speed Rail. It is important to decide train frequency influencing on scheduling method. Main factors to decide train frequency are location of station, social economic index, land use of station area and travel demand. In this paper, we focused on travel demand which is critical factor to decide train frequency. And we studied on standardized scheduling method. Simulation method is used to analyze the performance of explored method.

Train to Busan(2016) and Seoul Station(2016) contain trans-media properties in terms of the expansion of 'possible worlds' from the original story, and show the cultural and economic potential of the domestic trans-media contents with industrial systems added to the artist's competence of Dir. Yeon Shang-ho, an animator and film director. But they also have limits of the lack of continuity in time and characters between each media, various derived contents and suitable marketing strategy. For the development of Korean trans-media contents, it is necessary to extend the range of contents, find changes in production time and style, and improve the distribution environment to encourage a user to integrate contents from each platforms.

Nowadays, the technology development of communication and system engineering should impact on the Train Control System(TCS). The one of main developments in TCS is the Communication Based Train Control(CBTC), which does not depend on the track circuit. Currently, there are the project to modernize TCS as CBTC system from the track circuit system around the world. In Korea, there are the new CBTC system revenue projects such as Busan-Gimhae LRT, Sin-Bundang Line, and so on. There is also Government project called Maglev Line in Daejeon, which is applied CBTC system. Through the examples of world TCS renovation, it is expected to modernize the track circuit TCS system as CBTC system in Korea. Therefore, we would express the advantage of developing from the traditional TCS system to CBTC TCS system.

Noise levels of the three subway lines of Busan city have been investigated. Averaged cabin noise of the train has been measured during the train trip for each station. It has been measured with separation of day time (9:00~18:00) and night time (18:00~22:00) measurements but there was no big difference on the measured data. Repeating for the measured data has been confirmed with twice measurements in May and June 2010. Several noise effects to the subway noise levels of Busan are explained. Those are screen door effect, rail road surface condition, subway train type and curvature of railway. Among three subway lines of Busan city, the line 2 is relatively noisy and its reasons are studied. It has been shown that the screen door effect is 10 dB(A) and S shape of sharp curve contributes in high noise level.

A series of filed tests have been performed to investigate the aerodynamic effects on platform of the railway station during the passage of train that can be unpleasant and even dangerous to the pedestrians. To assess the aerodynamic effects on the platform, two aerodynamic properties has been measured; one is the wind gust induced by the train and the other is the pressure pulses generated when the nose and the tail of train passes. To measure these aerodynamic properties during the train passage, an array of hot-wire type anemometers and several sets of pressure transducers have been used, respectively. This paper deals with the filed test on conventional railway at about 100km/h operational speed, in which total 34 measurements has been made at the Bugok station in Seoul-Busan line for Saemaul-ho and Mugungwha-ho train. The results showed dramatic differences in the aerodynamic features between the two trains that are supposed to originate from the contrasting nose shapes of the trains.

Theoretical study has been conducted to clarify pressure characteristics of KTX(Korea Train eXpress) in tunnel. The external and internal pressure of rolling stock have been measured by using the atmospheric pressure sensors and portable data acquisition system on Seoul-Busan high speed railroad line. These pressure change may give rise to the ear-discomfort for passenger and fatigue for car body. In this study, the tunnels from 200m to 4000m in length have been chosen for the investigation of tunnel length effects. From the results of experiment, the pattern of pressure change generally agrees to RTRI's experimental result for Shinkansen. We found that there are similar patterns of external pressure variation for each critical tunnel length. The critical tunnel lengths are governed by train speed, train length and sonic velocity.

Urban transit operation is to manipulate the vehicle or train of urban transit to be operated on the basis of the installations such as track, power, communication, signaling and so on. It can be performed by manual or automated, or manned or manless operation considering its system built, operation efficiency, safety, etc. Because of the heavy impact directly to the safety of passenger transport, it has been managed strictly by the Regulation for Train Operation of Urban Transit according to Urban Transit Act. However, the present regulation has been basis of the manual operation mainly, it is crossing beyond the limitation of application to the manless operation which is being introduced moment to moment. It is needed increasingly to revise the regulation for the manless operation which is close at hand now. In this paper, we examined and analysed the cases of manless operation of urban transit planed within the country such as Busan 4th Line, Shinbundang Line, Busan-Kimhae Line, etc. based on the present regulation, and proposed the review of considerations to reflec the manless operation to the regulation to be revised.

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.

Metro serves more than a basic function of transporting passengers between short distances but became a crucial part of civic culture due to the fact that citizens demand various facilities for better life style. Therefore, domestic metro cuts off train noise and air dust, provides pleasant platform surroundings by offering effective HVAC, and establishes PSD (Platform Screen Door) system to prevent falls into train tracks. To control and interlock EMU Door and PSD to avoid passenger complaint and revenue service obstructions, stability and reliability of on-board & wayside equipment are required foremost and each line needs to build optimum interface between on-board & wayside equipment. To control PSD, we would like to introduce examples of Busan Metro(BTC : Busan Transportation Corporation) which already utilizes interface between on-board & wayside equipment in various ways and consider optimum interface between on-board & wayside equipment in future PSD system.
