The intelligent railway operation information architecture is to provide the railway passengers with the intermodal transportation information service. The purpose of the information architecture is to suggest the information service architecture of the intermodal transportation structurally. First, the architect procedure is to analysis the user requirements and according to these requirements, is to make the description of service requirements. Then secondly, it decides the service items and based of these items, it is to construction of service architecture. Finally, service package provide an accessible, deployment oriented perspective to intelligent railway operation information architecture

At present, European railways in U.K., Sweden, and Belgium have taken serious efforts to improve railway services by implementing a service evaluation system. Not only do they measure the service-related performance of a railway system, but also operate an incentive system according to the results of service-related performance. This performance evaluation system can be also used to provide basic data for other policies such as fares, subsidies and track user charges etc. After the restructuring process of Korean national railways, therefore, although it is expected to face many difficulties in the future, it is desirable to implement a performance evaluation system for securing the long-term growth of Korean railway industry.

The purpose of this thesis is to know and understand the user requirements to provide with intelligent railway information service in response to the Ubiquitous environment. The railroad specially has a disadvantage of door-to-door service, however by using the information and communication techniques, we can provide the passengers who are using the intermodal transportation means with the realtime information, therefore we can overcome the above disadvantage. To deduce the passenger's needs for providing the future-type railway information service, we introduce the results of the questionnaire. In chapter 2, we studies on the concepts of intelligent railway information service, and in chapter 3, we investigate the cases of Japan and China, and in chapter 4, we study the passager's satisfaction by the questionnaire concerning the railway information service and suggest the needs for information offering.

Now operating lines of many urban railway are currently in progress in the Seoul, but the inadequate consideration of links between different lines could create inconvenience as the public transport. This paper is studied about the connection service design of urban-railway convinced for other metropolis railways forms and propose the base pilot plan of the railway network linking system in Seoul Metropolis.

According to separation policy between rail infrastructure and operation, the National Railroad Administration was converted to Korea Railroad Cooperation on Jan, 2005. That makes railway service assessment regarded as essential. About this matter, Section 15 of the Framework Act on Rail Industry Development and section 26 of the Rail Business Act shows that the railway service assessment should be conducted every 2 years. The government can officially announce the result and give orders operation company to improve service level. In the first railway service assessment in 2006, the principal railroad lines and stations were investigated. Rail supply service index and customer satisfaction index are introduced. It includes service items of supply, reliability, convenience, safety and customer satisfaction. This study presents the contents of 2006 rail service assessment. Some points of assessment which should be improved are analyzed as well.

Recently, there are many problems of service qualities such as regular-rapid-safe -comfortable transport, that was traditionally advantages in urban railway transportations. These problems cause train delays that affects consecutive schedule, capacity, operation plans, and it is hard to prevent the propagation of delay and find the recovery solution. Because the urban transport demands is continuously increased and the railway service is also expanded, the railway operation company makes efforts to improve operation performance and efficiency for passengers. In this paper, we analyse the issues and problems existing in the major operation line of high-density urban railways, and suggest the development direction of intelligent operation technology to improve the urban railway service by minimizing the occurrence and propagation of delay. And the result of numerical case study is also presented.

The purpose of this study is to prioritize the importance of urban railway service quality through statistical analysis. This was done to maximize customer satisfaction by providing customers of urban railway services (including LRT), operated by the local government, with a better customized service quality. It was hoped that this project would boost the need for public transportation by increasing customer satisfaction, which would eventually lead to more profitable revenue. The results of validity certification of expectations and perceptions before and after the use of government funded urban railway and private sector invested urban railways show that there are gaps for 18 items for the government funded urban rail projects (p<.01), while there is no significant difference for 2 items between expectation and perception (p>.05); private sector invested urban railway projects show differences for all 20 items (p<.001). Therefore, IPA analysis is conducted to improve the service quality; this should lead to a remedy that focuses on service quality. The findings of this study will contribute to providing management strategies for boosting customer satisfaction and creating revenue through customized service quality in the urban railway operating industry (including LRT), which is currently suffering from chronic deficits.

This paper shows the institutional limits of technological innovation at the railway package service, that is the limits of introducing the package express system. The railway package service, owned by government and operated by D company, has been suffered severe operating loss since early 1990's. The package express system supported by information network and co-working with inner city quick service might be an solution for the railway package service. But there are several obstacles such as labor union and the rigidities of the Korean National Railroad of government agency.

It is very important to delivery timely and safely items in logistics. So, the home delivery service system is introduced by many enterprises. Also, the beginning in 1990's, the rapid increase of automobile increased logistics cost and led to road stagnation. So, the railway transportation use in logistics can be considered. The railway transportation in home delivery service system can overcome the limit of transportation by land. This study evaluate railway transportation in home delivery service system by economical efficiency and timeliness.

One of railway communication technology, LTE(Long Term Evolution) based LTE-R(LTE-Railway) is rapidily adopted to supply various control signal and to supply diverse communication service be needed for safety operation of train. In this paper, railway communication technology and service based on LTE-R is studied. And domestic an international standardization trends of related on railway communications are investigated. Results of this study can be used as basic data for research of railway communication based on LTE-R and development of railway communication systems.
