A nonlinear programming model for evaluating public transit fare system is proposed. The model finds transit fare level and the structure that maximizes gross fare-box revenue subject to constraints on minimum ridership and the form of the fare equations. It is assumed that the demand for transit is a function of fare and its own-fare elasticity. It is assumed that the demand for transit is a function of fare and its own-fare elasticity. It is also assumed that the conditions including fare of the other modes are unchanged ; i.e., partial equilibrium. Empirical study has been performed for the case of Seoul subway system. This study includes an analysis of fare structure ; flat system and distance-based fare system. Sensitivity and comperative static analysis for elasticity has been also demonstrated.

This study shows the functional contribution into the public transportation system for congestion area. And there is a introduction for the rapid bus transit developed in Europe community. It can be classified the public transportation as urban transit, subway and bus. For a few years, it has been introduced the AGT system as a role of the alternative and lengthening system of subway line. Recently, there is going on construction of AGT system in some regional cities. The AGT system has advantages in terms of accessibility and cost-effective rather than subway. But the bus system is advantageous at the points rather than AGT system. It is obvious that the bus system is most cost-effective for infrastructure and system rather than any other public transports. If the bus system has punctuality and precise docking, that becomes best choice for public transportation scheme. There are tries to develop new systems by means of the f1les up the advantages in bus and AGT system, which can be classified as BRT(Bus Rapid Transit}. The idea is simple; 'Thirik rail, use advanced buses.' It is introduced the IRISBUS system at this article, which was developed in Europe community. And it is introduced the project architecture to develop the similar system to IRISBUS in KRRI through National Transportation Key Technology R&D Project

본 연구는 카셰어링의 대중교통 접근성이 카셰어링 이용수요에 미치는 영향을 분석하는 것을 목적으로 한다. 이를 위해 수원시에서 운영 중에 있는 그린카의 대여이력 데이터베이스와 대중교통 GIS DB를 활용하여 카셰어링 대여소별로 대중교통 접근성에 따른 카셰어링 이용수요 모형을 구축하고 이를 해석하였다. 연구 결과 카셰어링 대여소로의 접근수단은 도보가 73%로 가장 많으며, 자전거 3%, 버스와 도시철도는 20%로 나타났다. 버스와 도시철도의 접근성이 반영된 카셰어링 이용 모형의 적합도는 0.818로 대중교통 접근성은 유의한 변수임을 확인하였다. 즉, 카셰어링의 대여소는 대중교통과의 환승이 용이한 장소에 설치되는 것이 보다 이용수요를 증진시킬 수 있음을 확인하였다. 특히 대중교통 수단 중 버스 접근성은 유의한 변수로 확인된 반면, 도시철도 접근성은 유의하지 않은 것으로 나타났는데, 타 대중교통 수단과의 상호 이용수요 증진 측면에서 도시철도와 카셰어링간의 원활한 연계를 위한 환승할인 및 편도 반납 정책 등 다양한 보완적 정책이 필요할 것으로 판단된다. 본 연구 결과는 카셰어링에 대한 기초적 연구에 불과하지만, 대중교통간 환승수요를 증진시키는데 기여할 것으로 기대된다.

Pusan Metropolitan City has developed 'HANARO Card' system. It is a sort of multi-function card systems which has devised to resolve many traffic problems, to improve public transportation services, to build advanced transit information systems, to encourage reasonable operation of the public transit companies, and to obtain basic informations for devising transportation policies. This study aims at reviewing the systems of 'HANARO Card', analysing the situation of usage of the card, and suggesting some issues for improving the system. Main finding is that the major effects of the introducing HANARO traffic card are convenience (to pay a charge) in using transit, public parking lots, city freeway toll for citizens, and saving in personnel expenses, maintenance expenses for buses, subway and taxi companies. It is also found that HANARO traffic card system needs to be expended to be compatible with other fields of economic activities.

Metropolitan rapid transit system plays an essential role in the public transportation system of any large city, and its managing agency is usually charged with the responsibility of storing and managing the design drawings of the system. The drawings are important and historically valuable documents that must be kept permanently because they contain comprehensive data that is used to manage and maintain the system. However, no study has been performed in Korea on how well agencies are preserving and managing these records. Seoul Metropolitan Rapid Transit Corporation(SMRT) is the managing agency established by the city of Seoul to operate subway lines 5, 6, 7, and 8 more efficiently to serve its citizens. By the Act on Records Management in Public Institutions(ARMPI), SMRT should establish a records center to manage its records. Furthermore, all drawings produced by SMRT and other third party entities should be in compliance with the Act. However, SMRT, as a form of local public corporation, can establish a records center by its own way. Accordingly, the National Archives & Records Service(NARS) has very little control over SMRT. Therefore, the purpose of this study is to research and analyze the present state of storage and management of the drawings of metropolitan rapid transit in SMRT and is to find a desirable method of preservation and management for drawings of metropolitan rapid transit. In the process of the study, it was found that a records center is being considered to manage only general official documents and not to manage the drawings as required by ARMPI. SMRT does not have a records center, and the environment of management on the drawings is very poor. Although there is a plan to develop a new management system for the drawings, it will be non-compliant of ARMPI. What's happening at SMRT does not reflect the state of all other cities' metropolitan rapid transit records management systems, but the state of creation of records center of local public corporation is the almost same state as SMRT. There should be continuous education and many studies conducted in order to manage the drawings of metropolitan rapid transit efficiently by records management system. This study proposes a records center based on both professional records centers and union records centers. Although metropolitan rapid transit is constructed and managed by each local public corporation, the overall characteristics and processes of metropolitan rapid transit projects are similar in nature. In consideration of huge quantity, complexity and specialty of drawings produced and used during construction and operation of metropolitan rapid transit, and overlap of each local public corporation's effort and cost of the storage and management of the drawings, they need to be managed in a professional and united way. As an example of professional records center, there is the National Personnel Records Center(NPRC) in St. Louis, Missouri. NPRC is one of the National Archives and Records Administration's largest operations and a central repository of personnel-related records on former and present federal employees and the military. It provides extensive information to government agencies, military veterans, former federal employees, family members, as well as researchers and historians. As an example of union records center, there is the Chinese Union Dangansil. It was established by several institutions and organizations, so united management of records can be performed and human efforts and facilities can be saved. We should establish a professional and united records center which manages drawings of metropolitan rapid transit and provides service to researchers and the public as well as members of the related institutions. This study can be an impetus to improve interest on management of not only drawings of metropolitan rapid transit but also drawings of various public facilities.
