The challenge to be faced in public transportation today is to satisfy human needs with the least delay, with the smallest number of accidents, and with the most economic use of energy, space, materials, man-power and money. One possible solution may lie in city train system, including AGT system. Specially, Passenger space in AGT is important to balance the budget of layout with passenger's satisfaction. This study focuses on lay-out and space, comfort which should be considered from the conceptual design stage of the interior layout work. Traditionally, the interior layout of the passenger room has emphasized ridequality and style. However, as the train becomes more prevalent and versatile, the focus also tends to shift toward layout and space to have comfortable circumstances. After all, the purpose of this research focused on arrangement a rational interior layout of the train through ergonomics research. Finally, the key was ensuring the comfortable environment based on cultural background of the passenger.

The station area development planed to improve the old and narrowed station and to enhance the train passenger's convenience through private capital attraction in the past. But it has been faced with difficulty for the creative of transfer demand. Because of lean upon building facilities were caused by shortage of business profitability as to development of the upside a railway line, and lack of public utilities. The station area development requires that it's trend to large scale development of station areas, korail's direct development, deputation of specialty company to development, collaboration between local government and korail in development, diversification of process & installed facility, building multi-transfer center and one-stop transfer system. This trend caused by low profitability in development of the upside a railway line. The purposes of study are to make the system and law reflected to the property of station area development, investment in kind of needed land, and change railroad areas to high-rise and complex development, and make a forum between government and korail, etc.

Maglev System is expected to be a new public transportation for future because of its special characteristics. Sleepers of railway role on transferring the lateral load to guideway for Maglev and controlling the distance between rails. Variation of distance of sleepers can affect dynamic responses for maglev guideway. In this paper, Daejon maglev guideway is analyzed to find proper tie spacing of a maglev system. The analysis included using a maglev trainload and also the dead load as the primary forces on bridges. Not only the dynamic behavior of bridges is investigated under sleeper conditions, but also impact factor about vertical displacement on the guideway is produced. This guideway is analyzed in four cases followed by changing spacing of sleeper and then obtained dynamic characteristics such as displacements, acceleration and impact factor by Finite Element Analysis.

The urban railway system is a convenient public transportation system, as it carries many people without increasing traffic congestion. However, air quality in urban railway environments is worse than ambient air quality due to the internal location of the source of air pollutants and the isolated space. In this paper, characteristics of particulate matter (PM) pollution in urban railway environments are described from the perspective of diurnal variation, chemical composition and source apportionment of PM. PM concentrations in concourse, platform, passenger cabin, and tunnel are summarized through an analysis of 34 journal articles published in Korea and overseas. This information will be helpful in developing effective policies to reduce PM pollution in urban railway environments.

In this paper, we present a study on an AI-based system utilizing the CCTV system within city buses to predict the intentions of boarding and alighting passengers, with the aim of preventing accidents. The proposed system employs the YOLOv7 Pose model to detect passengers, while utilizing an LSTM model to predict intentions of tracked passengers. The system can be installed on the bus's CCTV terminals, allowing for real-time visual confirmation of passengers' intentions throughout driving. It also provides alerts to the driver, mitigating potential accidents during passenger transitions. Test results show accuracy rates of 0.81 for analyzing boarding intentions and 0.79 for predicting alighting intentions onboard. To ensure real-time performance, we verified that a minimum of 5 frames per second analysis is achievable in a GPU environment. his algorithm enhance the safety of passenger transitions during bus operations. In the future, with improved hardware specifications and abundant data collection, the system's expansion into various safety-related metrics is promising. This algorithm is anticipated to play a pivotal role in ensuring safety when autonomous driving becomes commercialized. Additionally, its applicability could extend to other modes of public transportation, such as subways and all forms of mass transit, contributing to the overall safety of public transportation systems.

The evaluation of public transit service quality is more complicated than evaluating other aspects of transportation service. Although various measures of effectiveness [MOEs] for transit service have been studied and applied, a more comprehensive and accurate MOE is still required. In the past, either data from user surveys or the experience of bus agency administrators and/or engineers used to measure the quality of service. However, recently, with reliable and accurate real time data from BMS(Bus Management System) and BIS(Bus Information System), more reliable and accurate MOEs are available. This study develops a service evaluation model from users' perspectives, which is based on user' cost models that consider passenger access time, riding time, waiting time, and discomfort due to in-vehicle overcrowding, violation of traffic laws, and accident rate. For validating proposed model, data from the BMS and transit-fare cards (T-Money Card) for Seoul's No. 472 main bus line were used. Models developed in this study provided reliable results.

Accumulated deficits resulting from managing the Korean Railroad and debts from the construction of the KTX (Korea Train Express which is a high-speed rail system) have left the Korean Railroad faced with great troubles. Since it changed into a public corporation Korail on January 1st, 2005, the Korea Railroad has been making unceasing efforts to overcome the troubles and improve its management. However, even these efforts haven't worked in the face of the improved conditions of other transportation methods such as better networks of land roads and air ways. The Korea Railroad had its revenue from its railway transportation limited, and has tried to expand its business to non-transportational areas. In some metropolitan cities, the Korea Railroad made investments in real estate by constructing station buildings based on private money. Yet, in small and medium size cities, the Korea Railroad has little particular strategic projects for business development. Recently certain small and medium size regional cities began to plan on business developments for the ex-railway land, and some small towns have developed real estate on the ex-railway land. Nevertheless, there have been no systematic case studies to classify these real estate developments.

This paper examined closely on the application of the private securities to the measures for countering terrorism. It is related to the fact that the role of human information comes into the picture nowadays. On closer examination of the application of the private securities to the national facilities, transportation, and multi-use facilities, it was found that having consistent commissioned education through the private-public cooperation and enacting legislation for allowing armed guard to board ships, making private security guards to use sniffer dogs, placing private security guards in each subway station is required, and the active publicity campaign of the government concerned needs to take place for directing and setting up the system for supervising managers of the authorities and changing the way they think of countering terrorism.
