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

In this paper we deal with a design of the evaluation system to assess the vehicle operational control algorithm for Personal Rapid Transit(PRT) system. PRT system is different from the conventional rail traffic system in such that the station is off-line so as to guarantee a very short headway. In this study we propose an evaluation system to assess the performance of the proposed vehicle control algorithm. The evaluation system is composed of virtual vehicles, central control system, virtual wayside facilities, monitoring equipments. The virtual vehicles are made up by the laptop computers and the central control system employs Power PC process of Motorola Inc. The wayside facilities are implemented by employing the PXI module of the National Instruments Corporation. In order to test the proposed evaluation system a test algorithm is used, which has been simulated in the combined simulation system between Labview Simulation Interface Toolkit and Matlab/Simulink.

Personal rapid transit (PRT) is getting attention as a new form of transportation. It is energy efficient and provides the high level of passenger service. In this study, the dynamic PRT dispatching and routing problem is dealt with. Passengers request transportation service on a complex network, and an operating system monitors passenger arrivals and coordinates vehicles in real time. A new online dispatching and routing algorithm is proposed, which minimizes the total travel distance of vehicles and the waiting time of passengers. The algorithm dispatches vehicles by considering multiple vehicles' state and multiple passengers at the same time. In particular, finding the shortest-time path is attempted by taking into account the future congestion on lanes. Discrete-event simulation is employed to validate the performance of the proposed algorithm. The results show the algorithm in this study outperforms others.

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

Personal Rapid Transit (PRT) is the emerging personal transport vehicle operating on the loop automatically. The PRT system utilize the electrical power from super capacity or battery, it is important to manage the power or energy. In this regards, the management of high temperature occurred by the operation of system is significantly important to prevent from serious damage of component. In this study, we studied the adequate shape of underbody which can reduce the heat accumulation by pickup coil and condenser using natural air cooling. We suggested the additional air pathway, air inlet and flow separator to decrease the temperature of the heat source components. It was found that suggested system can decrease the temperature of PRT under body by 16% during the static mode and by 10% during the running mode at 30km/h. It is expected that the findings of this study will feed into final design of newly built Korean PRT vehicle.

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

To solve the traffic problems increased in the big cities, a lot of local transportation authorities are taking into account the New Transit system. But most of projects are pending due to the financial and technical issues. New Transit system has various kinds of characteristics in the view of system technology and operational features. The introduction of PRT system into the Korean market can be investigated through the comparison with other new transit modes.

PRT(Personal Rapid Transit) system is a new transportation system which will meet increasing demands of traffic in Korea. It is also an environment-friendly transportation and automatically operated. For these reasons, researches on the PRT system are actively undergoing, but the PRT vehicles have different forms of subway, bus, etc. There are no design standards to evaluate structural integrity, yet. In this paper, Structural design specifications are derived, which are based on the performance test standard for EMU and the ASCE-APM standards. We also perform the static and fatigue analyses by FE simulation and suggest strategies to improve an initial structure design. In addition, we derived the design specifications for energy-absorbing structures to meet the conditions of the collision scenarios predefined from a view point of operation safety.
