Rail transport has grown over the Past decades, and rail networks have highly concentrated in urban area, and it is possible for rail passengers to choose a route anions a number of alternative routes. Analysis of factors influencing the choice of route, are required to estimate the rail travel demand of each route. In this paper, we describes route choice model for the transit assignment and characteristics of the route choice(i.e., by relative travel time and fares), and attempts to estimate travel demand of new rail transit based on the slated preference(SP) survey data of Nanko Porttown, which is located in Osaka, Japan.

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.

The objective of this study was to estimate the dynamic behavior of a personal rapid transit(PRT) track system using a rail of rectangular tube section and a rail joint of sliding type, and to compare the results with the normal rail and rail joint of a PRT track system by performing field measurements using actual vehicles running along the service lines. The measured vertical displacement of rail and sleeper, and vertical acceleration of rail for the normal rail and rail joint section were found to be similar, and the rail joint of sliding type satisfied the design specifications of the track impact factor for a conventional railway track. The experimental results showed that the overall dynamic response of the rail joint were found to be similar to or less than that of the normal rail, therefore the rail joint of sliding type for PRT track system was sufficient to ensure a stability and safety of PRT track system.

Metro, as a kind of city rail transit, is a modem city passenger transit system with mass transportation and independent special rails. It has become a backbone of the traffic in the metropolis and an important modern symbol of a city. A modem traffic system is indispensable for Shanghai to be an international metropolis of finance, trade and economy. At present, Shanghai metro line No. 1 and its extension have been put into operation, metro line NO. 2 will be put into trial operation by the end of 1999, the Pearl Line, an elevated rail transit system is under construction and other lines will be constructed later according to the plan. But the funding of the city rail transit construction (both metro and light rail) is a big difficult problem to the infrastructure construction of the metropolises either at home or abroad, which is also a problem to restrict the development of the city rail transit of Shanghai. We have learned from the internal and external experiences of the rail transit construction that it is an important means to deal with the funds of the city rail transit construction to actively utilize foreign funds. It makes up the shortage of the internal funds on the one hand, the external advanced science and technology and the management experiences can be introduced on the other hand. In order to discuss and study conveniently with you together the new problems appearing in the metro construction and to open up a new train of thought, this article will give out a certain analysis and description to the funding method in the metro construction of Shanghai and the characteristics of utilizing foreign funds in the rail transit construction as well as the problems which we are faced with.

According to the current eligibility criteria in Korea, only cities with populations of more than one million are eligible to carry out urban rail transit construction projects. This paper suggests measures for improving such systems by reviewing current eligibility criteria for the construction of urban rail transit including subway and LRT in Korea.

It is expected that standardized framework for urban rail transit system will contribute to more convenient and safe traffic service and ensure higher reliability and availability of urban rail transit rolling stock and infrastructure. Information and telecommunication system in urban rail transit consists of various subsystems, such as radio communication system, digital transmission system, integrated monitoring system and public addressing system and its standardization will be implemented based on these subsystem. Public addressing system is to provide information related to operation and emergency for passengers and operators. In this paper we suggest draft criterion of public addressing system for urban rail transit through functional analysis and comparison on the present state of the system.

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.

With designing alignment of railway for urban rail transit, a greater attention is paid to the riding safety and the comfort of the passengers. Especially, cant, transition curve, minimum curve radius are considered as very important alignment factors for the curve. For the above alignment factors, in this study, comparative studies on the design criteria of foreign rail transit are conducted. And reasonable design criteria of the alignment for urban rail transit are proposed.

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.

In the design of the light rail transit which is more reliable and economical, it is essential to develope a efficient third rail system. Especially, the analysis for the conductivity of conduct rail and the wear of collecting shoe is the first step of its development. In this paper, experiments for conductivity in conductor rail, wear in collecting shoe were performed respectively as different materials of conductor rail and current collector. Noise level and interruption, wear and contact resistance of collecting shoe were proposed as design parameters for the development of this system. Experimental equipment and methods of design parameter stated above were proposed, which is expected that analyzed results will be used as a basic data for the development of the system.
