The saloon light is the device that can offer convenience and comfort to the driver and passenger when the train is operated at night or in the tunnel. Generally, The fluorescent type saloon for the rolling stock have been used, but the problems that are short life and the generation of heat have been brought about because the saloon lihgts of rolling stock are supposed to operated continuously long time, and high power consumption. So, the development of new type of saloon lights has been requested in order to solve these problems. And recently the various LED type lights have been developed and LED type saloon lights for rolling stock also has been developed. Therefore, we survey the characteristic, function and needed condition of the LED type saloon lights for rolling stock, and analyze the good and bad point, and then research the complement of weak point. We want to find the direction and develop the design of future LED saloon light type.

The "standard regulation" of the vehicles from "urban transit law" are being adopted to electric multiple unit in domestic. In the standard regulation, there are two types for EMU. One is heavy EMU for Seoul. The other is large EMU for Pusan, Daegu, Gwangju, Daejeon, Incheon. Korea Railroad Research Institute, with the assistance of the Ministry of Land, Transport and Maritime Affairs, "advanced EMU development project" are progressed, and 6th year started at September, one unit to six cars is completed. Now "urban transit vehicle performance tests are on the current progress. The main characteristics of AUTS(Advanced Urban Transit System) are as follows. One inverter control one motor, DDM(Dircet Drive Motor), no driving gear, plug door and steps, mounting and maintenance costs down, passenger convenience improvement. This paper describes the key features the next generation EMU, and performance test results, and the commercial success method of national R&D business.

Proper door effort is required for the safety of passenger and pedestrian while securing door operating convenience. 3D finite element analyses for a hybrid door checker were carried out to estimate door checker arm resistance force. And, from the estimated door checker arm resistance force and theoretically calculated self-closing force, door effort was predicted. The analysis results at checker arm peaks showed excellent correlation with the test results. Also, in order to reduce solving time, a modified model with simple spring element was investigated. Finally an equation to easily calculate checker arm resistance force from checker arm shape and spring constant was suggested and its usefulness in early design stage was discussed.

Ergonomic ship design aims to improve the safety and convenience of crew and passenger. Recently, ergonomic design is a key issue in the warship design, as a basis of analysing and evaluating ergonomic design and evaluation methods for warship, existing military design guidelines and navy criteria in the fields of ergonomics were surveyed. Also, the methodology including ergonomic human model was introduced. Finally, it is shown that the ergonomics evaluation of a design at the early stage of warship design can be performed using commercial ergonomics evaluation model such as Delmia's ERGO.

Recently interior of a country have been innovated driverless LRT(lightweight railway train) that has a virtue of reducion of payroll cost, decrease of headway and improvement of speed. But, if driverless LRT will be happened a accident, response capacity considerably have low. And then passenger will have feel fear. This thesis had examination a IEC 62267 : AUGT safety requirement and analyze safe facilities of the inside and outside of the country. Later on, this result will have not only increase economics, reliability, convenience and safety but also set standardization standard.

ISO6954:2000 (Mechanical vibration - Guidelines for the measurement, reporting and evaluation of vibration with regard to habitability on passenger and merchant ships) has taken effect as the governing body for vibration regarding habitability due to ship vibration. However, ISO6954:2000, when compared ISO6954:1984 (the first draft of ISO6954), needs to clear some deficiencies concerning convenience and reliability during field applications. In this paper, ISO6954: 1984 and 2000 are proposed on their revisions in the future.

Based on fuzzy logic algorithm this paper constructed fuzzy logic controller for automated vehicles. For passenger´s convenience especially comfortability controller need to reduce the frequency of input variable´s changing. So we established membership functions for comfortability as well as speed following. It made possible to control comfortability directly. To demonstration the efficiency of fuzzy logic controller, we carried out simulation with a automobile´s transfer function. First, we designed the PID controller by using Ziegler-Nichols tunning method. Second, we calculated time response for each controller, then we compared the speed patterns of fuzzy controlled system and PID controlled system. Also we compared the difference of input variable ...

There should be a need for measures to build up environmentally friendly transport system with new town for residence being built near metropolitan area. In order to promote the development of station influence area, convenience for public transport users and LRT(Light Rail Transit) construction, request for the speed improvement of urban transit is on the rise for easy access to the metropolitan area. This paper delves into the efficient operation of high speed train suitable for passenger demand estimates, and seeks to ensure integrated transportation system with subway Line 9 following the construction of Gimpo urban railway.
