The personal rapid transit (PRT) system is a small scale transportation system that employs a novel concept to solve the traffic congestion problem in the city area. The PRT system is a driverless on-demand system that a passenger calls a vehicle rather than waits for the vehicle. Therefore, one of the most important issues in the PRT system is how to control the vehicle with the satisfaction of the basic concept of the PRT system. In this paper a computer simulator is introduced to evaluate the vehicle. operational control algorithm of the PRT system. The. computer simulator has the commercial embedded processor boards that operate in the real time operating system and pre-designed vehicle control algorithm is coded into the processor boards. The experimental results present the effectiveness of the proposed evaluation apparatus.

소형궤도 차량 시스템(PRT: Personal Rapid Transit)은 짧은 거리에 비교적 많은 승객을 수송하기 위하여 매우 짧은 차간 간격을 요구하며 또한 차량 간의 충돌을 피하기 위해서 매우 정확한 차량 속도제어 알고리즘을 필요로 한다. 본 논문에서는 소형궤도차량 시스템의 차량의 충돌회피 알고리즘 개발을 위한 장치의 구성에 대해서 다룬다. 개발 장치는 모의 차량, 중앙제어 시스템, 모의지상설비, 모니터링 장치로 구성되며, 설계된 알고리즘의 모의시험을 위해서 Labview Simulation Interface Toolkit과 Matlab/Simulink가 결합된 모의시험 환경을 이용한다.

Railway has been pointed to the efficiency of transportation, rapid transit, and comfortable train ride. the construction of railway near the downtown area and station building are increasing for maximization of utilization and convenience. but the heavy of transportation and rapid transit lead to increase noise and vibration. the noise and vibration of railway may cause the civil appeal, decline in the serviceability and insufficiency of environmental standard. In this study, floating slab system which is one of the solution to avoid noise and vibration in railway has been introduced, and analyzed floating Slab Track into arrangement of reduction material of vibration. As a result of analysis, It was estimated the bearing installation though slab have not a negative factor and terminal arrangement of reduction material of vibration have advantage for static behavior.

On December 2001, Yongin Light Rapid Transit was started with the Notification of Basic Plan for Private Infrastructure Investment Project and promoted as BTO configuration to effectually cope with the rapid increase of traffic demand in Yongin City and establish pleasant and green urban traffic system to connect with New Boondang Line to diversity traffic demand around roads. On May 27th, 2005, it was applied authorization of detailed plan and the .First Light Rapid Transit in Korea shall be started construction on Nov, 2005, and completion on May. 2009. This Thesis will introduce the Detailed Design for Yongin Light Rapid Transit.

Lightning is one of hazards affecting the rapid-transit railway system. There are two effects, which are direct lightning surge to electric car line and induced lightning surge. Protection methods for the direct lightning surge are studied with various occasions, however, study of induced lightning surge is insufficient in spite of a large or small effects. In this paper, it is analysed the way that serge voltage is induced to electric car line by lightning strikes. By modeling the propagation process and the coupling phenomenon of electromagnetic wave produced by lightning strikes, it is achieved to make integrative circuit model combined with existing electric car model. The study is conducted into three different waveform of electromagnetic wave produced by lightning; rectangular wave, double exponential distribution wave, triangle wave. It is also simulated that the inducing serge is coupled to electric car line in an arbitrary location. The simulation results in that, when rapidly changing rectangular wave is supplied, maximum power is induced to electric car line.

The noise and vibration of railway may cause the civil appeal, decline in the serviceability and insufficiency of environmental standard. In this study, floating slab vibration and repeated connection of devices to support joints and fatigue stress analysis of punching shear performance review was conducted to evaluate the safety.

We need to make the standards of maintenance information for urban transit to reduce the cost to maintain the information and to share the information with maintenance workers. It is enable to do systematic maintenance for urban transit by using the information system based on the standardized information. In this paper we propose the major items to standardize and the methods to lay out the standard schemes to enable structured maintenance. We present the 4 items, bill of material, material classification, accident/fault classification, electronic document, to standardize. And we propose how to implement the information system for urban transit based on the standardized information. We describe the implemented information system in two parts; a rolling-stock and an infrastructure part. And also we describe the result of survey to evaluate the system installed at Seoul Metro and Seoul Metropolitan Rapid Transit.

최근 철도는 운송수단으로써 그 역할이 증대되어 대량화, 고속화, 쾌적화를 지향하고 있다. 나아가 활용성의 극대화, 이용자 편의성 증대 등 다양한 목적을 위해 도심지 및 건물인접구간을 통과하는 철도 및 역사부설도 증가되고 있는 실정이다. 그러나 열차의 대량화, 고속화는 기존에 비해 증가된 소음 및 진동을 유발하며, 이러한 소음과 진동은 인접지역의 민원유발, 구조물의 사용성 저하, 소음진동관련 환경기준치 초과 등 다양한 문제를 야기할 수 있다. 따라서 철도의 소음 및 진동저감 관련기술개발은 철도건설에 있어 필수적이며, 향후 고속철도노선의 확대로 그 중요성은 더욱 증대될 것이다. 본 논문에서는 철도 및 선하역사의 소음 진동저감을 위해 플로팅 슬래브 궤도시스템(floating slab track system)을 소개하고자 하였으며, 이와 관련된 방진재의 개념도를 작성하고, 시스템의 기초해석 및 기본설계를 수행하였다.

Small Rapid Transit System(SRTS) will be defined fully automated urban transit system providing a rapid and personalized door to door transport service. Conventional forms of public transit require passengers to collect in groups until a large vehicle is scheduled to travel on predetermined routes. In contrast, SRTS offers personal transport with no waiting, and takes passengers non-stop to their chosen destination. This is a transport system which is as convenient as, or in congested environments more convenient than, the car, but with minimal environmental impact. Accordingly the foundation study of choice system size for development of SRTS
