  • This study will analyze what is favorable of urban structure in order to introduce new transit system like bi-modal tram. As a reasonable transport mode in a city, the bi-modal tram needs to be considered with respect to the space structural pattern and city growth process. The result of this study may provide the basic resource that helps transport decision makers to decide how to introduce bi-modal tram by considering the urban structural characteristics. Also, the results that analyzed a functional characteristic of a bi-modal tram with a effective urban polices will be informative for practical use.

  • In order to assure the safety of train operation, a safety function analysis corresponding hazardous events of railway accidents and a safety requirement review on operation & management of trains have been performed. The preconditions and train composition requirements such as safety principles and functions that should be essentially considered to enable the safety operation of Urban-Transit trains are clearly presented. On the basis of presented train composition requirements, a rational revise of Urban Railway Operation Rule is proposed. It will be helpful in accident prevention and safety improvement for railway operation.

  • It is one of the most effective method for improving the performance of electric railway vehicles to make better the wheel-rail adhesion characteristics. To study adhesion characteristic is to develop the equivalent reduction machine to experiment on the adhesion system. The experiment system makes it possible to change the wheel-rail adhesion force with various adhesion parameters, and therewith to test the adhesion control system with the reduction machine in a laboratory. In this paper for improving adhesion performance show actually control methods.

  • Urban transit consists of signaling system, railway systems, power facilities systems, information and communication system and the other complicated facilities. There are many new technologies to analysis the requirement of for information and communication system. The more system is complicate, the more system design error occur frequently in development of information and communication system. Now, we need to reduce the error by analysis the behavior of the requirements of it. Thus in this paper, we suggest the way to analysis the behavior of the requirements by using the computer aided design tools.

  • An Electric railway system has the characteristics. The train powered by substations generates regenerative power when it runs on railway of various slope. A regenerative braking is an ideal system on account of reducing mechanical braking as well as recycling the energy. This study dealt with the line gradient review, train running records and power data out of substations in a bid to establish the efficient regenerative energy storage system.

  • This paper presents an intersection of technologies of ITS (intelligent transport systems) and CBTC(communication based train control) in urban transit system. ITS is based on Information and communication technologies. And also these techniques are fundamental for railway system. ITS has some technologies useful in railways such as traveler information service, public transportation information service, and advanced vehicle control Systems. Therefore, both systems need to technological cooperation. In this paper, we proposed useful an cooperation method for both systems.
