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.

Light rail transit system has many characteristics of better accessibility, frequency service, low construction cost, reduced air pollution and medium-capacity public transport etc. Light rail transit system as a urban transportation system has been growing worldwide since the late 20th century. More than 300 cities around the world have light railway systems. Many medium-size cities in domestic site is planning the construction of light railway. This paper describes the development strategies for the light rail transit industry.

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.

경량전철(LRT: Light Rail Transit)은 중량전철에 비해 많은 장점을 가진 효과적인 대중교통수단이다. 따라서 많은 지자체에서 도입을 추진하고 있고, 부산광역시에서는 이미 반송선과 부산김해경전철 등 2개 노선을 국내 최초로 무인운행방식으로 도입하여 운행중에 있다. 본 연구는 이렇게 도입된 경전철과 관련한 이용자 측면의 서비스 만족도를 분석하고, 부족한 부분을 보완하여 경전철의 서비스를 개선해 나가는 데 우선순위를 제시하였다. 본 연구에서는 실제 무인자동운전 경량전철(부산김해경전철과 반송선)의 이용자를 대상으로 설문조사를 실시하여 경량전철에 대한 안전성 의식과 서비스에 대한 이용만족도를 파악하고, 구조방정식 기법을 활용하여 두 개의 서비스 이용만족도 모형(반송선모형과 부산김해경전철모형)을 구축하여 비교 분석하였다. 분석 결과 이용자 중심의 경전철 서비스 개선대책과 우선순위를 도출하였다.

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.
