Both traffic congestion and air pollution in the metropolitan area can be greatly relieved by promoting the use of public transportation with zero emission system. Bus and subway are very convenient means for the people moving in the route areas. But they are not enough to satisfy handicapped or old people to have access to them and also do not solve environmental problems completely. New vehicle system, fuel cell track rapid transit, will be introduced as a countermeasure for such problems in the present paper.

수요응답형 순환교통시스템(Personal Rapid Transit: PRT)은 자동차에 버금가는 승객의 요구 대응성 및 최적경로 운행으로 인한 높은 효율성 등의 특징 때문에 미래형 신교통수단으로서 많은 주목을 받아 왔다. 하지만 수송 분담 능력(4~6명)에 비해 건설비가 많이 들어가고 기존에 운용되고 있는 타 대중교통시스템과의 역할 분담 문제 때문에 적용에 한계가 있는 것도 사실이다. 따라서 본 연구에서는 도시 내 유연한 운용과 타 교통수단과의 연계를 목적으로 PRT 차량을 위한 수직이송장치를 개발하였다. 기존의 물류 분야에서 많이 채택되고 있는 순환 컨베이어 방식을 응용하였으며, 특히 연속이송이 가능하며 사이클 타임이 적은 장점이 있다. 이와 더불어 1/10 스케일의 모형의 제작을 통하여 장치의 기술적인 운용 가능성을 확인하였으며, 이를 통해 구조적 안정성을 확보하기 위한 방안을 도출하였다.

This study proposes a new methodology to estimate the traffic capacity of a personal rapid transit(PRT) system. The proposed method comprises three steps. The first step models the guideway network(GN) of PRT as a digraph, where its node and link represent a station and a one-way guideway link between two stations, respectively. Given local vehicle control strategies, the second step formulates the local traffic capacities through the nodes and links of the GN model. The third step estimates the worst-case local traffic demands based on a shortest-path routing algorithm and an empty vehicle allocation algorithm. By comparing the traffic estimates to the local traffic capacities, we can determine the feasibility of the given GN in traffic capacity.

PRT(Personal Rapid Transit)는 유형 또는 무형의 전용궤도에서 자동으로 승객의 요구에 따라 출발지에서 목적지까지 최적의 경로로 논스톱 운행하며, 높은 접근성과 프라이버시 보장 등 자가용 수준의 서비스 제공이 가능한 대중교통수단으로서, 최근 새로운 미래교통시스템으로 재조명받고 있다. 본 논문에서는 PRT 시스템의 연계 운행 효율성 극대화를 목표로 수직이송장치를 연동제어하는 PRT 운행제어시스템의 제어모듈 및 시뮬레이터의 설계 및 시험결과를 제시하였다. 수직이송장치부의 PLC는 운영제어센터 또는 역제어시스템과의 인터페이스를 위해 Modbus 프로토콜을 적용하여 설계되었으며, 원격제어시스템으로부터 명령을 전달받아 동작하는 자동모드와 수직이송장치에 설치된 센서검지 상태에 따라 독립적으로 동작하는 수동모드로 구성하였다. 또한, 실제 차량이 운행하는 환경에서 가상의 차량운행 시나리오를 적용하여 실제 차량과 가상 차량을 혼합하여 운행할 수 있는 3D 그래픽 기반 PRT 운영제어 시뮬레이터를 구현하였다.

Promote competition in local government and the construction of a subway construction in the vicious cycle of debt due to the operating deficit as a greater burden on local finances was leave. This government policy of public transport in the center of the metro construction costs affordable and to respond appropriately to public transport demand new transit LRT(Light rail Transit) by introducing the current Busan was the opening of Line 4, yongin line, Busan - Gimhae line, parliamentary and barge construction or ready for the opening. What is light rail, compared to the existing subway and cheaper construction cost, the existing road or bridge that runs along the track is installed, etc. Manless system construction cost and operating expenses as a possible new railway transportation has been a leading state-of-the-art mad. However, the domestic business system engineering of light rail-related companies in the developed countries are doing to advance to the national to the local engineering skills of the self-free, hurry will have to be secured. Therefore, this paper applies local light rail project on the status of the systems engineering analysis and based on this source of the latest engineering technology-intensive systems engineering to provide direction to the development of technology.

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

While the environment of usage of information and technology is getting stable and technology is being developed more deeply due to the globalization, making information, standardization, in order to make a fast response to the new industry strategy and business environment, mutual communication and management of correct and fast information are focused on as fundamental elements of keeping competitive power. Accordingly strategic development of urban transit operation organization, storage of information technology of urban railroad, and buildup of standard information infra are very important, so that computerized information system has been built up standardizing efficient maintenance framework of urban transit facilities. To maintain these facilities efficiently, storing the real-time information by standardizing the maintenance organization and building up computerized information system are very important with management of information history of existing maintenance work. Therefore, for the efficient maintenance of civil facilities among urban transit facilities, standardized facilities classification and definition of management elements, and the plan of designing and building standardized database about civil facilities through standardizing technology resources are described in this paper.
