The PRT(Personal Rapid Transit) system has been being researched and examined to efficiently provide high quality services to passengers against the traffic congestion of the capital region. With concept that PRT differentiated from GRT(Group Rapid Transit), PRT generally is a tracked vehicle system operating with unmanned. The embedded software of PRT Automated Control system generally is comprised of the central software, stations software and vehicle software. The controllers of these software interface to each other using its RF communication antennas. In this paper, each embedded software of the PRT system should be applied to an incremental and systematic test approach technique in the design and implementation phase, because the reliability and safety of the PRT system should be assured

Many structural engineers believed that RC underground structures like subway system might not be seriously damaged during earthquakes, until the Great Hanshin earthquake(a.k.a Kobe earthquake). But there is only one domestic seismic code of rapid transit system that established by Ministry of Construction & Transportation in 2005. Therefore, to investigate of current status on seismic design and evaluation method of rapid transit system is essential to estimate seismic performance of subway structural systems. In this study, comparing domestic codes and seismic evaluation methods with foreign system is performed.

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.

PRT(Personal Rapid Transit) is alternation mode of auto and advanced transportation system as future transportation mode cope with the situation caused by increasing traffic demand, vehicle, environment, energy problem. but there is no place where PRT is operated therefore it is necessary of study on application of PRT The purpose of this study is putting into shape of fundamental notion and role of PRT as transit system and studying of domestic application possibility We expect that PRT make transit will make variety and be able to connect with mass transportation facility, have a connection between trunk line and branch line, be a effective local transportation system within CBD, be a transportation system within leisure complex. This study focus on connection with mass transportation facility in the middle of 5 type, we class as. and we investigate application of PRT by process of making a choice applicable case area

본 연구는 Labview Simulation Interface Toolkit과 Matlab/Simulink를 조합한 제어 시스템을 매우 짧은 차간 간격을 요구하고, 차량 간의 충돌을 피하기 위해서 매우 정확한 속도제어를 필요로 하는 개인 고속 이동 시스템에 응용하는 것에 대해서 다룬다. 간단한 차량의 운동방정식을 유도하기 위해서 선형모터를 도입한다. 후미 차량에 의해서 추종되어 져야하는 속도 프로파일은 두 차량(선행차량과 후미차량) 간의 상태정보를 기초로 해서 생성된다. 속도 프로파일 추종을 위한 제어 시스템은 Matlab/Simulink 에 의해서 설계된다. 모의시험 결과는 제안된 제어 시스템이 속도 추종 특성을 평가하는데 효과적임을 보인다.

As the increased importance is placed on the new transit systems owing to the environmental pollution caused by the road traffic congestion, the policy for the introduction of the new transit systems as an alternative solution to ease the heavy burden of the construction expenses is being actively established. Since the explicit recognition of such transit systems and the review on the method of its adoption have been a pressing matter in the light of reducing the pending traffic congestion, the development of the rolling stock systems in modes of new transportation has been made in various ways taking into consideration the regional circumstances to alleviate traffic congestion, and offer a more efficient service with the application of their intrinsic characteristics. Such systems also have been developed as a mix of punctuality for railway systems operating on the runway and flexibility for buses. This paper, therefore, deals in more detail with 3 modes of systems such as low-floor articulated buses, GRT(Guided Rapid Transit) and tram cars, and studies the overseas cases of the operation of those systems involving both negative and positive aspects.

These days, in Korea, according to improving the standard living, people generally work 5 days a week and it results more leisure hours. On weekends or in specific season, travel to mountain region around the major city is much in demand, and, in case of public transportation, the demand exceeds the supply. So, people tend to go other places, even overseas, for their holidays. The situation in Korea reflects the needs for mountainous light rail transit system with the object of convenient and rapid transport of passengers. In this paper, the guideline for mountainous light rail transit planing is proposed, and the representative mountainous light rail transit system is analyzed to choose the proper mountainous light rail transit system which adapts the demand for transportation and the terrain in Korea.

Guideway Transportation will provide the break-through to solve the traffic problems, which a lot of big cities have over the world. APM (Automated People Mover) system, Guideway Transportation, is classified by PRT, GRT, and MRT according to the capacity of passenger to be carried by its system. In the Application of PRT (Personal Rapid Transit) system, the enact analysis of the traffic problem on the area to be applied should be preceded. PRT system is characterized by Off-Line and Demand Operation. The Network of PRT system depends on the Load Time and Load Pattern. The operation of PRT system will have move efficient way when it is applied to the network with evenly distributed Load Time and Load Pattern.

Railway is huge traffic system which is operated organically combining all the elements; vehicle, track, electric power, signal/communication, operation, etc. Safety level has ben improved steadily by learning lessons from past accident. But with rapid progress in high-speed, massive, high-frequency transit fresh idea of accident prevention is now in order. In quest of effective and efficient countermeasure, we aim to establish an adequate safety evaluation/management method. Our proposals are basic concept relating to safety analysis of fatal accidents, AHP of Saaty, Fuzzy AHP.
