최근 철도 민자역사 사업에도 민자유치에 대한 관심이 증가하고 있으나 체계적 사업관리방안의 미비로 인해 민자역사사업의 경쟁력 약화를 초래하고 있다. 본 연구에서는 이러한 문제점을 바탕으로 하여 철도 민자사업관리 활성화를 위한 개선방안을 제시하였다. 문헌 연구 및 전문가 면담조사를 통하여 국내 민자역사사업의 사업관리 및 수행의 문제점을 제도적인 부분과 업무상의 문제점으로 구분하여 $조사\cdot분석$하였다. 제도적인 부분에서는 민자사업의 수익성 저하와 사업자 선정방식이 도출되었고, 업무상의 문제점에서는 지자체 협의 및 인허가 행정 장기화, $사업 운영\cdot관리 미숙$, 타당성 분석의 미흡등이 파악되었다. 문헌고찰과 면담조사를 통해 나타난 문제점들을 근거로 하여, 사업관리의 효율화를 위한 사업수행체계 개선방안으로 투자비 회수 보장제도, SOC 민간투자사업과 동일한 제도적 지원, 사업추진의 전문성 극대화 방안, 사업주관자 선정방식 개선, 민자역사 협의기간 단축방안 등을 제시하였다.

An analysis of the railroad industry for R&D investments has been insufficient whereas there are lots of analysis of accumulation of technology, economic performances and ripple effects for macroscopic view and other industry of R&D investments. This study decided intellectual rights, patent, and paper as common indicators of scientific and technological performances for setting up performance targets through surveying and analysis of preceding study and verified a appropriateness of scientific and technological performances for railroad R&D 11 projects which were successfully finished. Preceding study has been set up performance targets by research investments as input, but this study made a performance target by model through a cross-sectional and residual analysis of performances of railroad R&D 11 Projects in applying research investments, capital investments, inner labor cost and inner labor cost per man and research time as inputs, and verified a validity and a empirical analysis through analysis of other project.

The rubber type AGT system is operated by driverless that signaling is CBTC type. The system function is acomplished exactly to obtain the safety and reliability of system and the system is designed to minimize risk. In order to design the system, the functional analysis is performed. Recently functional analysis is performed by RDD-100 which is used and verified by aerospace, military, etc. Therefore The design tool RDD-100 is used to perform functional analysis in AGT system development project.

According to the construction plan of Samcheok electric power complex from year 2009 to year 2020, many people are interested in this area. This national project which invests about 8.6 trillion won will have great influence to rail transport considering current depression days. Samcheok electric power complex will be the largest plan in Korea, and it is necessary to have railroad construction plan as soon as possible considering the route change of domestic coal transport and the possibility of coal transport by rail from North Korea, Russia and China after reunification of Korean peninsula. Also, Samcheok electric power complex will be located in the east area railroad route and it is important to study about this area. This study will mention about the railroad route of east sea north line and Pohang $\sim$ Samcheok line, and review the prospect and strengthening method of coal transport by railroad according to the construction of Samcheok electric power complex.

A multi-train operation simulation software is under development, in this G7 Project for a High Speed Train System, to simulate the running performance, power consumption, signalling and operation. In the first stage, a Train Performance Simulation (TPS) software is introduced in this paper. This is a core module of whole system and gives some parameters of a train, e.g., its position, speed traction and braking power and electric power system state, etc. In this paper, calculation technique was used for voltage drop at the train's positions and major posts along the catenary line. The final program will be used as an evaluation tool for system performance in constructing a new line or introducing a new train system.

Denoising, registering, and detecting changes of 3D digital map are generally conducted by skilled technicians, which leads to inefficiency and the intervention of individual judgment. The manual post-processing for analyzing 3D point cloud data of construction sites requires a long time and sufficient resources. This study develops automation technology for analyzing 3D point cloud data for construction sites. Scanned data are automatically denoised, and the denoised data are stored in a specific storage. The stored data set is automatically registrated when the data set to be registrated is prepared. In addition, regions with non-homogeneous densities will be converted into homogeneous data. The change detection function is developed to automatically analyze the degree of terrain change occurred between time series data.

It is expected that domestic railway vehicle operation companies may be subjected to GHG emission reduction when GHG emission system is enforced. This study aimed that reviewing on GHG emission system such as CDM, VCS and KCER, and analysing availability of GHG emission credit acquisition for railroad transportation sector. In order to estimate GHG emission credit, a GHG emission estimation methodology should be developed, which includes GHG emission baseline estimation and GHG emission monitoring method, MRV method and etc. Modal shift project, high speed train technology, straight lining project, mass transportation technology, operation optimization tehcnology and etc. may produce GHG emission credit.

The Seoul-Metro is the first city railroad corporation to operate RIMS(Rolling-stock Information Maintenance System). The development of "RIMS Project" and trial running task were started from Mar 29, 2001. Finally, this project was completed successfully on Dec 31, 2005, as integrated systems including light or heavy maintenance works in Ji-Chuk and Chang-Dong Rolling-stock Offices. After that, from 2006 to Dec 31, 2007, we promoted a this new program to other four rolling-stock offices (Su-Seo, Gun-Ja, Sin-Jeong) and the headquarter. For the duration of trial running, we developed and applied new complementary program having made up for the weak points or defects. The series of new program which were newly developed and applied are comprised of an operation management, trouble management, wheel management, heavy maintenance table automatic creation programs and ordering prediction programs to purchase goods smoothly. The Seoul-Metro have registered these programs(RIMS) to Computer Program Protection Committee. We'd like to introduce a composition of program for enhancement of a city railroad Information Systems.

To account for uncertainties involved in an economic analysis of project, sensitivity analysis are usually being done in Korea. Though useful for policy analysis, but it larks explicit consideration of probability of occurring certain events considered in the sensitivity analysis. Risk analysis otherwise can explicitly account for the probability of certain event which has dire impact on project viability, such as cost, discount rate, and size of benefit. This paper reports experience of applying risk analysis method for economic evaluation of railroad investment. Probability distribution of event has paramount impact on the risk analysis results, while not many prior researches dealt with these issues. Probability distribution of rolling stock cost and operating cost, in addition to those cost variables, are developed considering railway demand in this study. Case study results are reported. Issues in applying risk analysis are reported in addition to further research direction.
