  • Test Results of noise, ride comfort and vibration tests are investigated for three kinds of light rail transit vehicles which have passed the performance test and the test criteria has been satisfied. Noise level of light rail transit vehicles was 64~69dB(A) at stop and 74~75dB(A) when operated at full speed. The ride comfort index according to UIC 513R was 2.02 to 2.45. Vibration level of rubber tired light rail transit vehicle was from 'normal' to 'good' and that of iron wheel light rail transit vehicle was 'good' to 'excellent'. These data are the results for three kinds of light rail transit vehicles and more data can be accumulated after further performance test. These data can be used for a reference for the design of light rail transit vehicles.

  • A linear induction motor have advantages for reducing mechanical frictions and noises because it has thrust force by induced torque instead of friction force between rail and wheels. An it has additional advantage for reducing volume of bogie frame for light rail transit. The small volume causes the cost of construction down. Recently, researches of linear induction motor for thrust force of the light rail transit have been actively studied. For the rail transit, vehicle is running as follow accelerating and constant speed, finally decelerating speed passing local stops between stations. The light rail transit have only these three patterns of operating. Thus, design of that has different design specifications from others. In this paper, the linear induction motor for the light rail transit was designed considering the goal speed, accelerating time, and accelerating distance for approaching the goal speed. The designed motor was proved that it could meet the requirement of accelerating performance by2-dimensional finite element method and mechanical dynamics equation.

  • In general, a third rail current collecting shoegear is widely used in the light rail transit system since it is more efficient and economical than an overhead pantograph. Therefore, its specification is prescribed in the Korean standard specifications for the light rail transit for its applications. This paper describes the development of the third rail current collecting shoegears which is suitable to Korean situation and satisfactory to the Korean standard specifications. Two types are developed for the steel wheel and the rubber tyred AGT system, and various experiments are executed. It is found that performance of the third rail current collecting shoegear developed is proved acceptable.

  • 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.

  • LRT(Light Rail Transit), which has many merits compared with Heavy Rail Transit, is an effective public transport. Therefore, many local governments are pushing ahead with LRT. Busan had already adopted LRT(AGT)s like Busan Subway Line 4(Bansong Route) and Busan Gimhae Light Rail Transit(BGLRT) domestically for the first time. This study analyzes user satisfaction about the services of adopted LRTs and set right priorities of remeding their shortcomings from the user's perspective. In this paper, we surveyed safety consciousness and services satisfaction of LRT(BGLRT) users, and made two User Satisfaction Models of each LRT(BGLRT and Bansong Route) using Structural Equation Model. With established User Satisfaction Models(BGLRT Model and Bansong Route Model), we compared BGLRT and Bansong Route. Finally we found the measures and priorities for the improvements of LRT's services in the aspect of LRT users.

  • Many services have been served by the exiting subway systems since they have opened in 1975. But its efficiency and competition were going down because of the high construction cost and difficult connection with other transportations, etc. Otherwise, the light rail transit system is much lower construction cost than the subway and the high way building. Also those systems are good at the inexpensive operation cost, the fixed time and safety, the easy access. Recently, the several provinces are planning or advancing the light rail transit system because of these many benefits. Consequently, those system's economical feasibility analysis is required rapidly to show the resonable construction's cause and to get the private investment. This paper offers the system's economical feasibility through the several benefit analysis after the light rail transit system's construction.
