The purpose of this study is to analyze human factors - stress, alcohol, fatigue - of the railway driver in domestic railway industry. This study proposes railway safety improvement of domestic railway by intensively comparing railway safety system overseas to reinforce domestic railway safety. Domestic railways well known the well-organized railway safety culture has brought up safety issues on their process of private management. With this process, also, domestic safety is requested by increasing sense of the safety for general public. This study expects Korean railways to become a well-organized that as removing insecure factors of domestic railway based on result comparing and analyzing the manual, factors and requirements of guideline for internal and external safety culture.

Railway has recently played an important role in preventing global warming caused by green house gases and furthering a low carbon green growth, The various railway research centers have conducted facilitated studies on saving energy. In particular, urban railway has emerged as the best means of public transportation in terms of punctuality, safety and environmentally friendliness. There are various ways to save energy in terms of operation of urban railway system, and they can be generally divided into hardware aspects that pertain to structure of vehicles and development of control system and software aspects that pertain to effective operation of trains based on operation patterns and diagram control. In this paper, we investigated drive assistance system for railway energy efficiency. The railway operation patterns and train diagram management programs were researched.

The purpose of Railroad Vehicles License Management in accordance with the Railroad Safety Law is to improve the quality of railroad safety. And the train simulators come into use for training of train operation and testing to issue Railroad Vehicles License. So, It is very important that the simulators for the Railroad Vehicles License Test require to work correctly, to measure driver's operation quality in numerical system and to ensure the justice of license test. In fact, nobody can guarantee that the simulators are feasible performance to use in license test. The simulator for train driver license test can be used effectively for studying of needed performance and quality to test new driver's skill. This study hopefully provides the base for improving the quality of the simulator for train driver's license test and contributes furthermore to improve the simulator development technology and railroad safety.

The process of railway traffic planning is composed of several steps such as long-term, mid-term. short-term, and real-time plan. The planning of vehicle and manpower resources is a main research topic in tactical short-term planning step. Railway vehicle is usually consisted of a power car, passenger/freight cars and human resource is composed of engine driver, cabin crew, ground personnel. So far, power car was main research target in railway vehicle scheduling problem. Recently according as the light electric railway or high-speed railway is introduced, the operational planning of trainset vehicles become important, In this paper, we introduce the conceptional model for trainset restoring problem and developed heuristic algorithm.

Generally, Urban railway have special characteristics with short distance journey and minimum headway intercity transportation. These days, urban railway operators choose the driverless operation system without driver. On the contrary, Conventional & high speed railway utilize for long distance and high speed running. Because of special conditions of freight railway operation compared with urban railway, operation of conventional & high speed railway is showed very different characteristics. In this paper, We compares different operation scheme of urban railway and conventional & high speed railway and then present condition for train control system based on radio.

This paper presents expansible driver manager that is easy to upgrade each surveillance device linkage in synthetic circumstantial judgement system. Unlike conventional surveillance systems that use fixed surveillance device and provide finite sensing data, a proposed system extends devices that not only existing but also newly develop, additional. This driver manager collects datas of standardized type from a driver of new device that developed based on common interface through configuration. And then, that transmits datas gathered to synthetic circumstantial judgement part according defined tags.

This study aimed to reduce of traps incident of metro train door by suggesting preventive actions throughout analyzing why railway drivers and passengers commit unsafe behaviors which are human factors making occurrence of the incidents. The incident cases were analyzed and Incident Tree was structured by brainstorming with safety experts. In addition, the questionnaire survey was conducted for comparison with the analysis results. As the result, this study suggested driver's factors, passenger's factors, and public relation plan for safe use of metro in order to reduce the frequency of the incidents. For driver's factors, implementing job-rotation systems between railway and non-railway drivers, installing Object Detection Sensors between the metro doors and PSD, and flexible operation of dwell time were suggested. For passenger's factors, placing a platform safety person, installing a safety fence in front of the stairs and the elevators, and country wide public relations through mass media were suggested.

During normal subway rush hours, a train-driver is in charge of more than 3,000 people on a daily basis. When an emergency event occurs, millions of people and their property come to depend only on the train-driver's ability. After the Daegu subway fire disaster in February 2003, the Railway Safety Act was enacted in October 2004 and the 'Train Drivers' Licensing System' was introduced by the National Railroad Administration in July 2006 to secure and improve protection. This study was conducted to investigate and evaluate the effects of the Train Drivers' Licensing System since the Licensing System was first introduced eight years ago. In addition, the analysis will suggest better policies for the effectiveness of the 'Train Drivers' Licensing System'.
